Bioenergy Producers comment on California's Climate Change Scoping Plan

California Senator David Roberti (ret.) is a public servant of the first magnitude for California. I have met Sen. Roberti several times and hold him in highest esteem for his intelligence, his leadership, his respect for the lawmaking process, and socially sensitive policymaking. During his 28 years of service in the California legislature and 13 years of service as President Pro Tem of the California State Senate he provided superior understanding of the nature and process of governmental actions.

Relevant to California recycling and waste management law, he is also intimately familiar with issues that permeate the waste, recycling, and hazardous waste industry. David was chief Senate negotiator of AB 939, California’s landmark waste management legislation, and the author of California’s Hazardous Waste Management Act of 1986, the Hazardous Waste Reduction Act of 1989, as well as legislation establishing the California Hazardous Waste Hotline. After retiring from the Senate he was a member of the California Integrated Waste Management Board for four years. He is an innovator and friend of recycling who seeks to expand it in a clean and sustainable way.

Besides his law practice Roberti is also President of the Bioenergy Producers Association.

The mission of the BioEnergy Producers Association (BPA) is to advance the development and commercialization of sustainable, environmentally preferable industries that produce power, fuels, and chemicals from agricultural, forestry, and urban sources of biomass and plastic wastes.

Founders of this organization include some of the top waste management experts in California as well as two of the cellulosic ethanol technology pioneers - BlueFire Ethanol and New Planet Energy.

With such an experienced brain, law, and business trust at its disposal, the California Air Resources Board should take special note of the following comments submitted by Sen. Roberti on behalf of the BPA concerning the "Recycling and Waste Management" section of their California Climate Change Draft Scoping Plan.

--------------------
COMMENTS ON CARB CLIMATE CHANGE DRAFT SCOPING PLAN
(June 2008 Discussion Draft)

The BioEnergy Producers Association (BPA) is a coalition of private companies and public agencies dedicated to the development and commercialization of environmentally preferable industries that produce renewable sources of power, fuels, and chemicals from agricultural, forestry and urban biomass wastes and other carbonaceous materials. Our membership includes bioenergy firms, electric utilities, and waste management companies.

The BPA has reviewed the “Recycling and Waste” section of the Climate Change Draft Scoping Plan, and requests CARB’s consideration of additional measures for Landfill Methane Control. Landfill Methane can be controlled by disposing of carbon-based materials that would otherwise be landfilled in the process of producing liquid and electric energy using clean thermochemcial conversion technologies.

Specifically, the Recycling and Waste Sector Preliminary Recommendation should mirror and complement strategies outlined for the agricultural sector by encouraging the use of urban biomass wastes for sustainable energy production. Deployment of bioenergy strategies is consistent with the Bioenergy Action Plan, the Low Carbon Fuel Standard (LCFS), and AB 32 GHG reduction goals for the following reasons:

Landfill Abatement Potential

The Draft Scoping Plan recognizes fugitive landfill methane gas emissions as a major GHG precursor, and calls for measures to reduce the volume of materials flowing to land disposal. Existing source reduction, recycling, and composting programs are credited with attainment of the state’s 54% diversion rate, and the Plan places principal reliance upon the expansion of these programs to reduce disposal tonnages in the future, virtually ignoring the potential to use these waste resources in the clean production of liquid and electric energy.

Despite the success of its recycling and composting efforts, California’s high disposal rate has remained virtually unchanged for the past 20 years. 40 million tons of municipal waste were landfilled in California in 1989, the year AB 939 was passed. This year, despite the progress of recycling, 42 million tons of waste will be placed in the state’s landfills. As the state’s population is expected to grow by some 10 million people over the next 25 years, this trend is expected to continue.

It is folly to adopt the position that the volume of material that is being placed in California’s landfills can be significantly reduced through source reduction, traditional means of recycling and composting alone. All methods of disposal must be incorporated in any effective plan, and this includes the complete disposal (i.e., destruction) of carbon-based wastes in the process of producing the liquid and electric energy so desperately needed by the state.

Approximately 70% of the residual materials placed in landfills consist of various types of biomass, only a portion of which may be feasibly composted or recycled. In short, new tools are needed. For example, compostable organics (i.e. food and vegetative wastes), comprise only about 25% of this stream. Similarly, there is no estimate of additional biomass materials, such as paper, which may be recovered through intensified commercial recycling efforts, although markets for the major portion of this stream may have already been optimized, with residuals having limited commodity market value.

In contrast, new biomass conversion technologies, such as in-vessel hydrolysis/fermentation and thermal/fermentation processes, have the potential to convert the full spectrum of landfill-bound carbonaceous waste materials into renewable energy products, including power, fuels, and chemicals. Because of their unprecedented potential to divert waste materials to beneficial use, the development of clean technology bioenergy facilities is an essential and necessary component of future landfill abatement strategies.

GHG Reduction Potential

The Draft Scoping Plan notes that commercial recycling and composting programs “could have substantial greenhouse gas benefits but their in-state reductions have not been quantified at this time.” Indeed, data on the effectiveness of current waste management practices as climate change strategies are both inconclusive and incomplete.

Composting operations, for example, have their own set of air quality concerns, including VOCs and GHG precursors. In fact, an independent study recently completed by the Los Angeles County Sanitation Districts1 concluded that placement of urban green waste in landfills as alternative daily cover was superior to composting these materials in terms of net GHG emissions.

The climate change benefits of recycling are generally assumed to derive from the avoidance of virgin material extraction and reintroduction of recovered materials with “intrinsic energy value” back into the remanufacturing process, although the Draft Scoping Plan admits that such benefits may not occur in California. Indeed, the majority of California’s recyclables leave the state for distant domestic or foreign markets, with the largest volume of these commodities, namely paper and plastics, being shipped to China.

The life cycle analyses on which recycling climate change benefits are based seldom calculate the global GHG impacts of trans-Pacific shipping, or of transferring the remanufacturing burden to developing nations where environmental controls are minimal or nonexistent. These atmospheric industrial pollutants drift eastward and find their way back to California in a matter of days, contributing further to the state’s GHG reduction challenge.

The CIWMB’s own studies point out the critical need to both reevaluate and expand the range of technologies employed to meet future landfill abatement and climate change objectives. For example, a comprehensive life cycle analysis of waste management practices completed in 2004 by the Research Triangle Institute2 concluded that new waste conversion technologies (acid hydrolysis, gasification, and catalytic cracking) were superior to recycling and composting with regard to energy balance, NOx emissions, and carbon emissions. Similarly, a 2006 study of thermal waste conversion technologies prepared for the CIWMB by UC Riverside3 stated:

“If conversion technologies were able to process a significant portion of California’s waste that is currently landfilled, benefits could be realized in a number of areas. These include reductions in overall greenhouse gas emissions, fugitive landfill gas emissions, and diesel truck emissions. On the energy production side, the avoided costs and impacts in exploration, production, and transportation of traditional fuels could be substantial.”

This same study concluded:

“Thermochemical technologies can process a wider variety of feedstocks and can have a greater effect on landfill reduction. Thermochemical technologies can also produce a larger variety of products, which can displace the need for non-renewable sources of energy and fuels. Other indirect effects include eliminating diesel truck trips and reducing landfill gas emissions.”

Thermochemical conversion technologies are clean technologies because nothing enters the atmosphere as a result of the gasification (waste disposal) step. The resulting synthesis gases and waste heat from the processes can be converted to liquid and electric energy. The opposition to conversion technologies that is influencing legislative and administrative policy in California stems from those who refuse to accept that 21st century technology can achieve environmentally superior waste-to-energy technologies; from the traditional recycling industry which wants to suppress competition for the state’s waste streams and from waste management firms that view conversion technologies as threats to landfills.

It is time for the state to look past these short-sighted positions and embrace these emerging technologies with the same commitment as the federal government, other states and nations. More than 100 of these plants are now operating or will be constructed in Europe and Asia during the next decade.

California should be a leader in encouraging such technologies.
However, private enterprise will continue to take these projects elsewhere until the state adopts a practical, efficient and supportive statutory and regulatory environment for their implementation and operation.

Recommendation

The BioEnergy Producers Association supports the expansion of California’s source reduction, recycling, and composting programs. At the same time, we urge that new clean-technology bioenergy strategies be applied to the state’s growing post-recycled waste stream in order to meet urgent landfill abatement and climate change goals. Timely deployment of waste-based biorefineries can provide a vehicle for integrating California’s renewable energy, AB 118, and AB32 policy objectives.

CA Draft Scoping Plan comment: Recycling and Waste

This is one of a series of comments submitted to the California Air Resources Board for their draft version of the California Climate Change Draft Scoping Plan. Other BIOenergy BlogRing comments are linked here:
• Challenge the Status Quo
• Recycling and Waste
• Sustainable Forests
----------------

The Draft Scoping Plan correctly identifies recycling and waste management as a focus area for mitigation of greenhouse gases. According to CARB's own estimates, there are 40 million tons of unrecycled waste pouring into California's landfills each year. This is roughly equal to the amount that was accumulating before California's very successful recycling policies were enacted twenty years ago.

The California Integrated Waste Management Board (CIWMB) needs to pursue a more aggressive approach than merely extending methane capture and composting solutions. California's waste management companies already lead the nation in their efficiency for capturing methane from landfills. The closure of landfills, not methane capture, is the urgent problem that requires attention.

Composting is not a solution for two reasons: 1) the resulting compost does not meet a consistent purity standard to make it marketable and 2) the demand for compost is so low that these programs are not economically sustainable.

Environmental sustainability will only come with economic sustainability. For this reason Zero waste as currently defined by some recycling groups is an unattainable idealistic vision for which the costs will grow geometrically as it approaches zero percent. The biggest reduction in the rate of landfilling will come if clean conversion technologies, which are economically sustainable, are developed as an extension of recycling.

Most unrecyclable trash can be used for generating renewable electricity or converting into carbon-neutral biofuels. Some of our biggest landfills in our largest cities are scheduled to close within the next decade necessitating trans-shipment to other sites - sometimes hundreds of miles away. This is a waste of GHG emitting trucking and rail energy (see independent 2005 UC/Riverside analysis). Instead, conversion technologies sited at waste sorting facilities, a plan already under development in Los Angeles, can cleanly reduce the volume going to landfills by approximately 85%.

Without question, municipalities should receive diversion credit for redirecting unrecycleable biomass from landfills to conversion technologies that can cleanly produce bioenergy and bioproducts from the refuse.

I personally believe there should be a recycling integrity clause in the Scoping Plan that insures that all recycled waste is turned into products within California to reduce and control global GHG emissions. That is the only way that the hard choices about waste stream recycling, greenhouse gas emissions, and economic sustainability can be honestly addressed. Currently most recyclables are shipped to China (at great GHG expense) because of that country's poor wages, lack of workers rights, and appallingly low pollution standards.

Capturing energy from unrecycleable waste

Implementing new technologies to solve chronic problems is hard work. A generation filled with expectations of instant gratification is sure to be frustrated by the seemingly slow pace of change to correct obvious environmental challenges.

Take recycling for example. In the last twenty years we have made great strides to reduce, reuse and recycle trash from our waste streams as we hover around 50% diversion from landfills throughout major portions of California. And yet, with the simultaneous growth of volume of trash, we seem unable to reduce beyond that threshold.

Beginning in 2004 the County of Los Angeles engaged in a program to take a major leap forward in reducing the accumulation of seemingly unrecycleable waste that ends up going from county material recovery facilities (MRFs) to landfills. Their vision is to deploy emerging conversion technologies at the MRF that can cleanly reduce trash volume by as much as 85% without emitting toxins or greenhouse gases into the atmosphere. As a substantial bonus, renewable bioenergy could be captured through the generation of green electricity and/or biofuels - depending on which specific technology is chosen.

A team of seasoned experts have just issued an evaluation report of their progress to date. Titled the Los Angeles County Conversion Technology Evaluation Report: Phase II - Assessment it details the thorough screening and evaluation of technologies from throughout the world - Israel, Japan, Europe, and the United States - that are competing for deployment at one of the county's best suited MRFs.

In recognition of the public's interest in the program's operations and environmental sustainability, public outreach programs and state regulatory reform efforts are already underway. A decision on the final site and technology to be funded will be made in early 2008. In view of the environmental costs of doing nothing and the painstaking efforts the Department of Public Works and allied agencies are making to deploy a solution that is in the best interest of all stakeholders, the decision by the parties involved in this effort is certain to be one that deserves public support.

Below is the latest (October 31, 2007) press release on the report.

------------------------------
COUNTY OF LOS ANGELES RELEASES FINDINGS ON NEW ALTERNATIVES TO LANDFILLS
County report finds viable conversion technologies to tackle Southern California's looming trash problem

Los Angeles - 36,000 tons per day! That's how much trash is deposited into landfills on a daily basis from Los Angeles County. Within a few short years, many of those landfills will be reaching capacity. This includes the Puente Hills Landfill, currently the largest operating landfill in the United States, which will close in 2013. That leaves Los Angeles with one very large problem.

After years of exhaustive research and evaluation of conversion technology facilities from around the world, the County of Los Angeles has announced the official release of a report summarizing its findings and outlining the next steps in its conversion technology program. In the next year, the County will select one or more projects to be among the first commercial-scale demonstration facilities in the United States, laying the groundwork for a fundamental shift in how the region deals with its garbage.

"Los Angeles County is promoting cutting edge technologies that have been proven effective in Japan, Israel and Europe. Trash doesn't have to be a problem, it can be a resource for clean energy and other marketable products," stated Paul Alva, chair of the County's Alternative Technology Advisory Subcommittee.

Conversion technologies encompass a variety of advanced processes that convert normal household trash into renewable energy, biofuels and useful products. These technologies provide an alternative to landfills by offering a clean and safe way to turn residual trash (which cannot be recycled economically) into a valuable resource.

"Through first hand evaluations of operational facilities in Europe, Israel, and Japan, we have found that conversion technologies are viable and environmentally friendly means of managing our solid waste," said Alva. "These technologies offer real solutions to California's waste and energy crises."

The report identifies four viable technologies that are capable of managing Southern California's residual waste in a cost-effective and environmentally sound manner. In addition, the report identifies four recycling facilities where a conversion technology facility could be co-located. The County will request that these "short-listed" technology developers and recycling facilities form partnerships and submit formal proposals to be among the first commercial-scale conversion technology demonstration facilities in the United States. Early next year, a competitive bid process will determine which project will receive the County's support. A final decision will be announced by mid-2008.

The technology finalists are: Arrow Ecology (anaerobic digestion); International Environmental Solutions (pyrolysis); Interstate Waste Technologies (gasification); and Ntech Environmental (gasification). The site finalists are: Del Norte Regional Recycling and Transfer Station (Oxnard); Perris MRF/Transfer Station (Perris); Rainbow Disposal (Huntington Beach); and Robert A. Nelson Transfer Station and MRF (Rubidoux).

In conjunction with the report's release, the County has launched a new and improved conversion technology Web site. The www.SoCalConversion.org.

The mission of the Southern California Conversion Technology Demonstration Project is to evaluate and promote the most promising conversion technologies from around the globe, and work with communities throughout the region to develop demonstration facilities that showcase the technical, economic and environmental viability and benefits of conversion technologies.

Creating products from the residuals of bioconversion

One of the true achievements that came from the development of the petroleum industry is the creative ways that have been found to dispose of refinery residuals. The entire plastics industry owes much to the innovation of chemical companies like DuPont who found ways to take the "sows ears" of petroleum and make "silk purses" out of them - fibers, plastics, fertilizers, and chemicals. Unfortunately, many of these products are not biodegradeable.

For biofuels to compete successfully with fossil fuels, every part of "the pig" will have to have a separate profit stream. Distiller dried grains (DDG) is a good example since it is the primary byproduct of the corn to ethanol fermentation process. But researchers are looking to see if there are more profitable byproducts than DDGs. And what about the residuals of emerging processes like gasification, enzymatic hydrolysis, depolymerization, biodiesel production, etc? Can we sequester carbon in some of these products?

Biopact has an excellent update on new research that seek to expand the number of profit streams that make bioconversion development more financially viable.

Steps to biorefining: new products from biofuel leftovers

The vision behind the emerging bioeconomy is the creation of integrated biorefineries that turn any given stream of biomass into an optimal range of finished products, green platform chemicals and specialty chemical compounds. The goal is to make the processing steps as efficient as possible, and to have them 'cascading' so that one bioconversion step's 'waste' stream becomes an input for a next step. Ultimately, biofuels will be just one of the many renewable, low-carbon products and compounds manufactured in the biorefinery.

Many researchers are pursuing on this concept, and the most common approach is to utilize currently available byproducts from biofuels - distillers’ dry grain from corn ethanol, lignin from cellulosic ethanol or glycerin from biodiesel - as a starting point for research. But some scientists are going further already, and are adapting the biofuel production process itself in such a way that it may yield more interesting co-products. This is the way forward to genuine biorefining.

Navigating to Zero Waste in California

The non-profit California Resource Recovery Association (CRRA) recently held its 31st annual CRRA Conference and Trade Show in the coastal city of San Pedro in Los Angeles County attracting recycling professionals from throughout the state. The theme of this year's event was "Navigating to Zero Waste." As a global leader in the environmental sustainability field...

The CRRA works to expand markets for recycled materials, promotes sustainable materials policies and is a clearinghouse for information, innovation, and industry and governmental initiatives. CRRA newsletters, workshops and conferences provide up-to-the-minute information on issues that shape the recycling and composting fields.

Responding to the goals of California's landmark Integrated Waste Management Act (AB 939) of 1989 the CRRA is to be credited for helping communities throughout the state divert over 54% of its urban waste from landfills through recycling. What goes unrecorded is the amount of waste that never makes it to the municipal recovery facilities (MRFs) through many of the coordinated programs it has helped to foster and implement to significantly reduce the source of waste. This is achieved by identifying major sources of waste production and helping the producers recognize their responsibility to streamline wasteful and waste producing practices.

Unfortunately, "Navigating to Zero Waste" will never be reached simply through application of the 3 R's (Reduce, Reuse, and Recycle) using existing technologies at the rate at which waste grows in the state. Even if 60% of waste is diverted, the same principal volume is likely to remain. This threatens urban landfills like L.A.'s vast Puente Hills landfill (which will close in 2013) and a San Diego landfill (which will close in 2012) and other close proximity urban repositories. The remaining refuse will then be shipped at great expense and fuel usage to outlaying landfills as far as 200 miles away.

So it was heartening to see that two of the plenary speakers were Councilmember Greig Smith and California Integrated Waste Management Board (CIWMB) member Rosalie Mulé.

Greig is a refreshing example of a local politician who responds to the voting public by listening to their concerns, enlisting professionals to create a solution, and making sure that the solution gets significant political support that will outlive the terms of the signatories. L.A.'s 20-year RENEW LA plan obligates the Los Angeles Bureau of Sanitation to divert unrecycled trash to biorefineries located at MRFs thereby reducing waste volume by 85% while co-generating electricity and very possibly producing biofuels (biooils and ethanol). He reported that selection of the exact technology to be implemented at the first site will be made later this summer.

Rosalie Mulé was appointed to the CIWMB by Governor Arnold Schwarzenegger because of her experience working in the private sector waste industry. She reiterated the Board's commitment to advancing programs that minimize waste, manage landfills, promote producer responsibility, and maximize waste usage. She applauded the efforts of organizations such as CRRA to make California a leader in the world for how to create and implement recycling programs. During her speech she stated:

We also want to encourage innovations and technologies that will provide for the most efficient and effective management and reuse of material. There are a lot of new technologies on the horizon, some of them are proven and some of them are not but I like to compare them to space exploration. We would not have the things we have today had we not gone out there and conducted the research and done the exploration and navigated the uncharted waters.

It is time to move beyond the current established methods of waste reuse to develop new waste conversion alternatives. Many of these practices are being employed successfully in Europe and Japan where population density mandates technological solutions that place waste conversion facilities within close proximity to populated areas. We have the luxury of space but new popular standards, like AB32 the Global Warming Solutions Act, require renewed industry action on a timely basis.

Biomass and BioWaste Conference in Pittsburg this September

I have been in touch with Dr. Ines Freesen about a new conference that her company is co-hosting that will take place between September 25-27th in Pittsburg, PA. While there is plenty of excitement about corn ethanol and the emerging technologies surrounding cellulosic ethanol, there is a dearth of press and conference content about the most revolutionary concept of all - converting municipal solid wastes, sludge, factory smoke, agricultural, and forestry waste into biofuels and electricity.

This blog is an attempt to partially correct that media deficiency but the real headway will be made when pioneers in the field of waste-to-energy congregate, network, and fully explore the potential.

According to the conference website:

"energy from biomass and waste" can make a significant contribution to oil-independence and climate protection with clean power, heat, and vehicle fuels. The technology opens up new earning potentials and markets (domestic & international) for the waste management & power generation industry, as well as for new market players such as the agricultural sector. With this event we want to create the leading North American showcase and educational forum for this growth business.

Here is the press release from last February (posted on the Renewable Energy Access website) about the German/American collaborators behind this event.

-------------------
German-American Partnership To Promote Energy From Biomass and Waste
Freesen & Partner and Steel City Biofuels sign agreement to promote green energy, create international marketplace
Press Release from Freesen & Partner GmbH
Alpen,NRW, Germany / Pittsburgh, PA, USA, 21-Fe-07

The benefits of biofuels seem clear enough: they can provide a safe, sustainable domestic resource. But what does this mean for the business owner, for municipalities, the farm economy? How can the utilization of oilseed crops, switchgrass, manure, landfill gas, or residential waste make a significant contribution to save on energy and recycling costs, to reduce harmful emissions and create jobs?

Two partners from both sides of the Atlantic have joined forces to raise visibility for these issues and to create a forum that provides answers and practical assistance. Freesen & Partner GmbH, a Germany-based trade show organizer, and Steel City Biofuels, a Pennsylvania non-for-profit organization signed an agreement to use the EBW Expo & Conference, held on September 25-27, 2007 in Pittsburgh, PA to create an educational forum tailored to the information needs of multiple stakeholders.

The agreement was signed on February 15 as part of a ceremony for the signing of a Declaration of Cooperation between the Commonwealth of Pennsylvania and the State of North-Rhine Westfalia (NRW). Dr. Ines Freesen, Managing Director of Freesen & Partner, and Nathaniel Doyno, Executive Director of Steel City Biofuels, were joined by Pennsylvania Governor Edward G. Rendell and NRW Minister President Dr. Juergen Ruettgers.

"We are very excited about this new venture", comments Ines Freesen. "The time is right to think about what can be done with biomass and waste to reduce the world's unhealthy dependence on fossil fuels, and there could be no better place than Pennsylvania to hold the EBW Expo & Conference. Together with Steel City Biofuels we will create a truly international forum that offers hands-on information to a wide range of energy users and 'waste producers'."

"Thanks to the leadership of Governor Rendell and DEP Secretary McGinty Pennsylvania is poised to become a national leader in the production of energy from biomass and waste", says Nathaniel Doyno. "Steel City Biofuels is very excited to partner with Freesen & Partner on this venture because we feel that the EBW Expo provides an ideal platform to bring together the technology providers, energy users, investors, policy makers, and researchers that can really launch these industries."

The agreement is focused on:
- creating educational forums during EBW tailored to the needs of multiple stakeholders, including investors, farmers, green energy producers, cities and municipalities, businesses, students, and university researchers
- determining different options and media to promote the expo and conference to all relevant stakeholders in Pennsylvania, the United States, North-Rhine Westafalia, Germany, and other regions
- organizing site tours to bioenergy and energy-from-waste projects in South Western Pennsylvania during EBW
- develop business opportunities for Pennsylvania and German companies

Envirepel: Gasified waste-to-electricity in San Diego

I received a welcomed message from Anthony Arand, CEO of Envirepel Energy, Inc. who wished to clarify and expand on what has been reported here on the SDG&E press release:

I enjoyed reading your columns in trying to figure out what is our company really up to. Biomass diversion contracts? Honestly, that is the first time I have heard that terminology applied to a utility or us. Please allow me to fill you in on some of the specifics.

In San Diego County green waste is diverted as is all MSW waste via recycling, it has nothing to do with the Utility. SDG&E is after Renewable Portfolio Standard qualified suppliers of electricity, plain and simple. The connection of green waste and energy projects being restricted to green waste is incorrect.

There hasn't been a new combustion design for any type of solid feed stocks in over 50 years, the one we selected was first published in 1912, and this is where people tend to focus the discussion, on the technology. Think of it this way, people compare cars for horsepower, performance and emissions in a discussion about the type of engine the car has.....how many times have you heard them discuss the suspension, braking system, catalytic converter material selection, radiator size, or pressure drop across the system that allows the "car" to perform ?

You really don't care what technology you use, you care that the integration of those technologies (the system) works together to deliver the goals of the project. The key to clean energy generation with low emissions is to design a facility from top to bottom for that purpose using multiple technologies that when combined deliver what you want. That is what our company has done, and it is not typical to an industry controlled by bankers who don't care about the environment, and don't want to spend a nickel more than absolutely necessary to make money from a project.

Here are the design targets we set out to deliver with our facility design:

1. It can't produce emissions numbers above 15 ppm of regulated pollutants to stay under the air emissions offset thresholds for a 60 MW facility
2. It can't produce noise emissions (it has to be quiet and not bother the neighbors)
3. The fuel can't smell up the neighbor hood (ie, keep it inside the building)
4. The building has to stay under 45 feet tall from a land use building code perspective with all the equipment inside
5. After initial start up and capacity testing is complete, the solid fuel facility has to be dispatchable from zero capacity to full capacity in under 10 minutes
6. The facility has to be able to process and operate on any fuel stock (biomass includes wood, green waste, MSW, and non-recyclables)
7. A structural safety factor of three on all designs (earthquake country), and a performance safety factor of two on all system components, especially the emissions systems (reliability through redundant capacity)
8. All equipment, facility layout, and employee related safety issues are compliant with OSHA
9. Zero discharge facility from a water use or rainfall run-off facility.
10. Harvest as many pollutants and green house gases in the exhaust system as can be collected for re-use and resale (don't let money go out the exhaust)

We selected a modified gasification combustion system capable of running on any feed stocks to meet the needs of the facility design and are permitting the first ones on green waste to prove out the facility design before we construct facilities on landfills that run on post-recycled MSW.

Normally a developer only develops the site, somebody else builds it, a couple of banks then own it, and some poor schmuck gets selected to operate it and prays to the heavens that the guys the "developed" it didn't forget crucial issues on the equipment design and layout.

We chose not to go that route and went down the path to design, build, own and operate our facilities. That means we staffed up with engineers, planning, fabrication, machine shop equipment, and set about building our own equipment for our own projects.

We have operated our one to one scale demonstration test cell to show that the combustion system produces the low emissions we claimed, and our first facility in Vista will demonstrate how the system works when producing electricity with all the rest of the system equipment hooked up. The next three smaller projects are also all on green waste (easy to get and no significant air emissions issues) that allow us to flush out any design problems with the system (i.e are the bearings big enough on the conveyor belts, or is one grinder really capable of holding up to the load or should we use two types of operational and reliability issues).

After that, the system fuel stock shifts to post recycled MSW on all future sites, which happen to be landfills, and we help California truly become a Zero Waste State.

I hope that helps shed a little light on what we are doing.
