UK-based TMO Renewables has announced that it has entered into a 20-year contract with U.S.-based Fiberight to design and build waste to ethanol plants in the U.S. The contract is estimated to be worth more than $25 million per year. The new plants will combine the TMO Process, which optimizes waste feedstock conversion using a specialty bio-organism, with Fiberight’s fractionation and digestion technology. The two technologies working together are anticipated to improve the conversion of municipal solid waste (MSW) and other types of cellulosic waste into ethanol.

As part of the agreement, the two companies anticipate that they will design and construct 15 plants throughout the U.S. over the next five years. According to TMO, for each plant they will receive an initial, one-off design fee plus recurring annual revenue. The site and funding for the first plant has already been secured and construction is expected to begin in 2011. The next five sites have also been identified with the remaining plant locations yet to be determined.

“This contract is a landmark in the development of TMO’s technology on a commercial scale to produce an economically sustainable source of renewable biofuel,” said Hamish Curran, CEO of TMO. “In adopting the TMO Process Fiberight has proven the ability to use waste stream feedstock, net of all recyclables, for the effective conversion to cellulosic ethanol via a novel, low cost and fully integrated bio-process. Replication of similar waste to ethanol bio-refineries, across all regions of the U.S. and globally, can drive significant green job creation and community economic development. We look forward to working with Fiberight’s pioneering team to drive forward our joint plant development program.”

Last year, Powers Energy of America announced that it would build a $254 million waste-to-energy ethanol plant in Schneider, Indiana. According to an article published in the Post-Tribune, the bioethanol plant has received full commitments for funding. In addition to funding this plant, the investors have also now committed to supporting a $75 million solar plant. The solar plant will not be fully completed for five years, but upon completion will produce nearly 100 megawatts of electricity. According to the company, this will be one of the largest solar facilities in the country.

According to company President, Earl Powers, the solar plant could be operational by early next year. However, it will take some time yet for the bioethanol plant to break ground since it has yet to receive the appropriate environmental approvals. Regardless, Power notes that the two projects will provide much needed employment opportunities for the community.

A subsidiary of garbage giant Waste Management is buying a public utility’s waste-to-energy facility.

Wheelabrator Technologies Inc. has acquired the Southeastern Public Service Authority’s Refuse Derived Fuel (RDF) plant and adjacent waste-to-energy facility in Portsmouth, Virginia for $150 million:

The purchase concludes a lengthy process that commenced more than two years ago when SPSA began consideration of a proposal to sell the two plants in order to reduce debt and operating costs and draw on the expertise of a private vendor. Three other companies submitted competing bids. After narrowing the candidates to two, the Authority chose Wheelabrator on November 17, 2009. A newly constituted SPSA Board, which took office January 1, 2010 as a result of a change in state law, continued the sale process, ending with the Board votes on April 28.

SPSA will use the $150-million from the sale to pay down debt to the Virginia Resource Authority (VRA) and other lending institutions, and repay money owed to the City of Virginia Beach.

The 164 SPSA employees will now become Wheelabrator employees. The waste-to-energy facilities turn up to 2,000 tons a day of municipal solid waste (MSW) into 600,000 pounds of steam per hour and 60-megawatts of electricity. The steam will go to the Norfolk Naval Shipyard repair operations, with the electricity going into the grid.

S4 Energy Solutions has recently announced plans to develop a plasma gasification facility at Waste Management’s Columbia Ridge Landfill in Arlington, Oregon. The facility will covert municipal solid waste into clean fuels and renewable energy. Construction is beginning in early summer and the plant will be online by the end of this year. During construction, 28 people will be employed with 16 being permanent once the facility is operational. S4 is a partnership between Waste Management and InEnTec, a deal that was solidified in May of 2009.

“Our goal is to extract as much value as possible from waste and this project will help us recover valuable resources to generate clean fuels, renewable energy and other beneficial products,” said Dean Kattler, area vice president for Waste Management Pacific Northwest. “This project strengthens our focus on renewable energy and new technologies that use waste as a resource. We are committed to growing our business in this region in innovative ways, bringing green jobs to communities where we already have operations and community relationships.”

Using S4′s PEM process, waste materials are prepared and fed into a phase gasification chamber that operates at nearly 1500 degrees Fahrenheit. Once this phase is complete, the waste materials flow into a second closed chamber where they are superheated using plasma, an electricity-conducting gas. Ultimately, the intense heat rearranges the molecular structure of the waste converting it into syngas. From here, the syngas can be converted into ethanol or diesel or into industrial products like hydrogen or methanol.

This site also features a landfill gas-to-energy (LFGTE) facility which captures methane gas created during decomposition and to use for electricity which powers 5,000 homes in Seattle. Sixty-seven windmills also generate 100 MW of electricity at the landfill and the power is sold to PacifiCorp.

Jeff Surma, president and chief executive officer of S4 Energy Solutions, concluded, “Plasma gasification has garnered a lot of attention recently, as we look for new ways to sustainably manage waste while recovering valuable resources. We believe the project will demonstrate commercial viability of the new S4 integrated system, so that we can implement this technology at many other locations for a wide variety of applications.”

Waste Management Inc. has inked yet another deal to produce biofuels from waste. Today, they announced an investment in Montreal-based Enerkem Inc., as part of their new financing round. A portion of the CDN $53.8 million raised will be used by Enerkem to support the construction of its second waste-to-biofuels plant in conjunction with the City of Edmonton and Alberta Innovates. The funds were raised in combination with current investors and new investors Waste Management and Cycle Capital.

Back in December 2009, the U.S. Department of Energy awarded Enerkem US $50 million for the plant planned in Mississippi. Also in 2009, the company’s commercial-scale demonstration plant in Westbury, Canada went online and reached 1,000 hours of production.

“This financing round validates Enerkem’s business and advances our path towards leadership in the waste and advanced fuels markets,” said Vincent Chornet, President and Chief Executive Officer of Enerkem. “The financial and strategic support of these world-class investors, bringing together our existing investors with Waste Management and Cycle Capital, will accelerate the transformation of the waste-to-biofuels industry that Enerkem is marshalling.”

Enerkem’s  proprietary thermo-chemical technology helps convert waste materials into biofuels such as ethanol. According to the company, its technology is able to process diverse carbon-based feedstocks, including sorted municipal solid waste, construction and demolition wood, as well as agricultural and forest residues.

Tim Cesarek, managing director of Organic Growth at Waste Management said of the strategic investment, “We want to extract more value from the materials we manage than anyone else in our industry through new and emerging processing and conversion technologies. Combining Waste Management’s industry leadership and expertise in the collection and management of a wide range of segmented waste streams with Enerkem’s leading clean technology solutions, we are broadening our portfolio of conversion technologies in the waste-to-biofuels market which is key to developing new, higher value added end markets for materials.”

Waste Management continues to build its reputation in the development of alternative energy with the announcement that they have partnered with Harvest Power to expand next generation organics recycling facilities across the United States and Canada. Waste Management now joins founding investors Kleiner Perkins Caufield & Byers and Munich Venture Partners, as investors in the project.

The largest food and yard waste composting facility in North America, located in Richmond, British Columbia, is owned and operated by Harvest Power. In addition to building and operating large-scale organics recycling facilities, the company is also developing several high-solids aerobic and anaerobic digestion and composting technologies which will accelerate the decomposition of organic materials to produce renewable energy or biogas. Once the biogas is formed, it can be converted into electricity, liquefied natural gas (LNG) and into high quality, nutrient-rich compost products.

In a release today, Tim Cesarek, Managing Director of Organic Growth at Waste Management said, “We want to extract more value from the materials we manage than anyone else in our industry through new and emerging processing and conversion technologies. Combining Waste Management’s industry leadership and expertise in the collection and management of a wide range of segmented waste streams with Harvest’s leading technologies and industry knowledge will be key to developing new, higher value added end markets for organic materials and accelerating the growth of organics recycling across North America.”

North America generates over 180 million tons of organic waste each year and is a valuable resource for the production of renewable energy.

“Through partnerships with leaders like Waste Management, and by designing, building, owning and operating our own facilities, we will be turning more organic waste into renewable energy and high quality compost,” added Paul Sellew, Co-Founder and CEO of Harvest Power. “Our goal is to harvest the power in organic materials to create more sustainable communities, and we look forward to expanding our business with our new partner.”

Several ethanol plants have been changing hands and one of the more recent was the purchase of Xethanol LLC, based in Blairstown, Iowa, by Fiberight LLC, based in Virgina. Fiberight purchased the plant with the intent of converting it into a cellulosic ethanol demonstration plant. The fuel will be produced through the conversion of municipal sold waste (MSW) to ethanol. The company acquired Xethanol for $1.65 million and the conversion is estimated to be around $20 million.

The technology is not new to Fiberight which for three years has been operating a pilot-scale plant in Virgina. In an article published by Biomass Magazine, Fiberight CEO Craig Stuart-Paul said of their technology, “We’ve been operating in stealth mode because we don’t want to make claims until we can prove them.” They plan on doing just that in Blairstown.

While there are several MSW technologies, Fiberight says that its process is unique for several reasons. One is that their technology, “has the ability to fractionate the waste stream into various forms and then create a homogenous feedstock.” Stuart-Paul notes that this is the biggest hang-up for MSW technologies to date.

Second, Stuart-Paul said that their proprietary process allows the recycling and re-use of enzymes. This lowers costs and speeds up commercial competitiveness in that their fuel will be more cost-competitive with alternative fuels already in the marketplace.

According to the company, they are in negotiations to secure the waste from nearby Cedar Rapids, Iowa a community of 150,000 people that is less than 30 miles from Blairstown. These are the ideal communities for the company’s mini-mills and once the Blairstown plant is successfully running, Fiberight plants on siting additional plants in similar communities.

CE-CERT development engineers Junior Castillo (left) and Eddie O’Neil (right) display the results of the steam hydrogasification process that converts urban waste feedstock (rear container) into clean synthetic diesel fuel (foreground container). The fuel was produced in the lab-scale reactor behind them.

University of California, Riverside’s College of Engineering-Center for Environmental Research and Technology (CE-CERT) has been awarded a $1 million grant from the California Energy Commission to build a demonstration plant to convert biosolids to clean synthetic diesel fuel. As evaluated by the National Energy Technology Laboratory of the U.S. Department of Energy, this process is 12 percent more efficient and 18 percent lower in capital costs than all other mainstream gasification technologies.

The plant will use a steam hydrogasification process coined the “CE-CERT Process,” to convert biosolids from the the city of Riverside’s wastewater treatment facility, along with other ‘waste’  feedstocks, to produce energy. The state of California has committed to reducing its petroleum use by 2.4 billion gallons per year, and the intent for the fuel produced using this process is to be integrated into the transportation mix as a clean alternative to fossil fuels.

According to a UC Riverside news statement, California produces an estimated 83 million dry tons of biomass wastes per year, including agricultural and forestry wastes and wastewater treatment biomass that must be disposed of. Virtually 32 million dry tons of this biowaste are estimated available for fuel production.

According to researchers, the advantages of this process are many including access to a diversity of feedstocks that typically go to landfills, lower capital investment required to build a plant, and smaller plants can be located near the feedstock sources for an economic and environmental advantage.

Proof of technology of the pilot plant is the last step before full scale commercial production.

Using landfill gas to produce energy is real! Waste Management, in conjunction with Linde North America, has begun to produce renewable vehicle fuel at its Altamont Landfill near Livermore, California. The facility is the world’s largest landfill gas (LFG) to liquefied natural gas (LNG) plant.

The plant which was built and is operated by Linde, purifies and liquefies landfill gas that Waste Management, the largest services waste company, collects from the natural decomposition of organic waste in the landfill. The plant was built to produce up to 13,000 gallons of LNG per day. This is enough to fuel 300 of Waste Management’s 485 LNG waste and recycling collection vehicles in twenty California communities. Since the plant went online in September, it has produced 200,000 gallons of LNG.

Duane Woods, senior vice president for Waste Management’s Western Group said in a company press statement, “The Altamont LFG-to-LNG facility enables us to recover and utilize a valuable source of clean energy in another practical way, reducing our dependence on fossil fuels. Conventional LNG is already a clean-burning and economically viable alternative fuel for our collection trucks. The ability to use recovered landfill gas to fuel our hauling fleet offers significant environmental benefits to the communities we serve in California and is a great example of how we are committed to recovering resources in waste.”

The Altamont LFG-to-LNG facility meets two of California Governor Schwarzenegger’s environmental directives: the Bioenergy Action Plan, which seeks to advance the use and market development of biomass as a transportation fuel, and Executive Order S-3-05, which aims to reduce the state’s greenhouse gas emissions by 25 percent by 2020.

“Linde is proud to create a clean and green energy solution for residents of California. Landfill-gas-derived LNG is a super ultra-low carbon fuel, as designated by the Air Resources Board and the Altamont project is expected to reduce carbon dioxide emissions by nearly 30,000 tons a year,” concluded Pat Murphy, president of Linde North America.
