Waste Management and Enerkem Announce Strategic Investment - Waste Management Joins Rho 
Ventures, Braemar Energy Ventures, BDR Capital and Cycle Capital as Investor in Enerkem 
 
HOUSTON, TX, and MONTREAL, Feb. 24 /CNW-AsiaNet/ -- 
 
     Waste Management, Inc. (NYSE:WM) and Enerkem Inc., today announced a strategic 
investment by Waste Management in Enerkem, as part of Enerkem's new financing round. 
 
     The closing of this new round of financing which generated CDN $53.8 
million comes from Enerkem's existing institutional investors, Rho Ventures, 
Braemar Energy Ventures and BDR Capital as well as from new investors, Waste 
Management and Cycle Capital. The new funds raised will be used to support 
Enerkem's growth plan, including initiating the construction of its second 
waste-to-biofuels plant. Morgan Stanley acted as Enerkem's agent. 
 
     Enerkem's proprietary thermo-chemical technology helps convert waste 
materials into biofuels such as ethanol. 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. 
 
     "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," said Tim Cesarek, managing director of Organic Growth at Waste 
Management. "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." 
 
     "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." 
 
     In December 2009, Enerkem was awarded US$50 million in funding by the 
U.S. Department of Energy for development of its planned Mississippi plant. 
Its commercial-scale demonstration facility in Westbury, Canada, which was 
completed in 2009, reached 1,000 hours of operation. The new funds raised will 
be used to support Enerkem's growth plan, including construction of its second 
plant, in partnership with the City of Edmonton and Alberta Innovates. 
 
     The investment in Enerkem complements Waste Management's comprehensive 
waste services in the areas of recycling, landfill, waste-to-energy and 
landfill gas-to-energy. This investment will also help move Waste Management 
toward meeting three of its sustainability goals: doubling its renewable 
energy production and tripling the amount of recyclables processed by 2020, 
and investing in emerging technologies for managing waste.
