New study finds GHG emissions from palm oil production significantly underestimated; palm oil biofuels could be more climate-damaging than oil sands fuels

Green Car Congress

The majority (62%) of the plantations were located on the island of Sumatra, and more than two-thirds (69%) of all industrial plantations were developed for oil palm cultivation, with the remainder mostly being Acacia plantations for paper pulp production. Earlier post.).

Study finds that native microbes biodegrade longer-chain hydrocarbons in oil sands tailings to methane; implications for management of tailings and GHG emissions from tailings ponds

Green Car Congress

Proposed anaerobic hydrocarbon biodegradation pathways in oil sands tailings. The researchers now report that higher molecular weight n -alkanes (C 14 , C 16 , and C 18 ) are also degraded under methanogenic conditions in oil sands tailings, albeit after a lengthy lag (180 days) before the onset of methanogenesis.
