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. —Miettinen et al. Earlier post.).

Understanding the variability of GHG life cycle studies of oil sands production

Green Car Congress

In a paper published in the ACS journal Environmental Science & Technology , Stanford University assistant professor Adam Brandt reviews a number of recent life cycle assessment (LCA) studies calculating greenhouse gas (GHG) emissions from oil sands extraction, upgrading, and refining pathways—the results of which vary considerably.

Microbial Capacitive Desalination Cell could make treatment and reuse of oil and gas wastewater simpler, cheaper

Green Car Congress

Oil and gas operations in the United States produce about 21 billion barrels of wastewater per year, with accompanying disposal costs of about $5 billion per year. The saltiness of the water and the organic contaminants it contains have traditionally made treatment difficult and expensive. 1 activated carbon cloth (ACC) was harvested.
