Waste Management first In Ottawa with natural gas fueled waste collection vehicles

Green Car Congress

Waste Management (WM) is introducing 25 new Compressed Natural Gas (CNG) fueled trucks to collect waste and recycling in 2012 as a result of being awarded a collection district by the City of Ottawa. This means fewer miles driven and fewer emissions. —Sherry Stevenson, municipal affairs manager for WM.

Lufthansa, ETH Zürich, Climeworks & Synhelion to cooperate on Sustainable Aviation Fuels; CO2 capture & solar thermochemical conversion

Green Car Congress

Climeworks direct air capture machines are powered solely by renewable energy or energy-from-waste. Grey emissions are below 10%, which means that out of 100 tons of carbon dioxide that the machines capture from the air, 90 tons are permanently removed and only 10 tons are re-emitted.

Study finds renewable fuels from hydrotreated vegetable oils outperform transesterified lipids and BTL from woody material in environmental lifecycle impacts and costs

Green Car Congress

GHG emission comparison between fossil diesel, transesterified lipids, HVO and woody BTL. If HVO is produced from waste feedstocks with low upstream impacts, the high conversion efficiency of the HVO production process will make HVO the preferred fuel to BTL from any woody feedstock, even woody waste.
