Canadian biogas firm and CBA member Greenlane Renewables has won an $8.3 million biogas upgrading contract for a landfill gas to renewable natural gas (RNG) project in California. The company announced that its wholly-owned subsidiary, Greenlane Biogas North America, secured the contract with the customer whose name has not yet been revealed. Engineering work will begin immediately on the project upon completion of permitting and approval of submittals by the customer, expected by early-to-mid 2020. The new facility is expected to process 1,600 standard cubic feet per minute of landfill gas to produce roughly 97% pure biomethane, or around 360,000 MMBTU annually of clean RNG, for direct injection into the local gas distribution network owned and operated by SoCalGas.
A lot of media attention is currently given to the issue of per- and polyfluoroalkyl substances (PFAS). The issues for composting and anaerobic digestion facilities are the presence of PFAS in finished compost or digestate products, and the presence of PFAS in facility storm water runoff. Composting or digestion facilities that take in biosolids, industrial residuals, and food scraps containing grease-resistant food packaging are receptors of PFAS chemicals. Read Part 1 of a new BioCycle series that explores ramifications of PFAS in recycled organics and process storm water — and technology options to treat the contamination.
An article in The Western Producer on CBA member Greenholm Farms features the farm’s sustainability and digesters. The reuse of material is a key tenet of sustainability in agriculture, and Greenholm Farms, in Embro, Ont., just northwest of Woodstock, has taken that to heart. The owners, Gord and Laura Green, along with their son and business partner, Dave, have discovered that producing methane to generate electricity on their mixed dairy and crop farm creates what Dave calls the “circle of agriculture,” while offering good financial benefits as well.
