Its latest initiative involves the use of sustainable fuel made from landfill gas to run five of its home delivery vehicles in central London. The liquid Biomethane fuel for five Mercedes Sprinters that Waitrose uses to deliver groceries is being supplied by UK company Gasrec - the first commercial pr http://www.ecofriendnews.com/environmental_article9820.htmlTue, 3 Aug 2010 17:50:02 GMTThe Oil Firing Technical Association (OFTEC) have tested fuels which blended either 30% or 50% of the bio element, fatty acid methyl ester (FAME) with either kerosene or gas-oil. The FAME was derived from used cooking oil. The fuel that blends 30% FAME with 70% kerosene (B30K) has been accepted by the Government as eligible for the proposed Renewable Heat Incentive (RHI). If this is introduced http://www.ecofriendnews.com/environmental_article9818.htmlTue, 3 Aug 2010 17:44:08 GMTWith the escalation of landfill tax, a growing emphasis on recycling and recovery, new government incentives to encourage renewable energy from waste, and new technologies coming on stream, the opportunities for small and medium sized waste contractors have never been greater, especially in the area of commercial and industrial waste, where the volumes being generated in the UK are four to five ti http://www.ecofriendnews.com/environmental_article9806.htmlWed, 14 Jul 2010 14:07:42 GMTOriginOil, Inc. has announced a new invention that generates hydrogen from living algae, providing an additional energy source from bioreactors. In contrast to previously reported developments in the area, the new Hydrogen Harvester uses little or no external energy inputs, requires no sulfur deprivation or other "stressing" of the algae, and no genetic modification. The process employs viable, h http://www.ecofriendnews.com/environmental_article9805.htmlWed, 14 Jul 2010 14:05:49 GMTCurrently, most of the proposed methods in the biofuels-from-algae space require the extraction of immobilized oil from algal biomass. However, regardless of the oil extraction technique used, and some are more efficient than others, getting to the oil is usually very expensive in terms of capital and energy costs. In some instances, the amount of energy consumed to extract the oil can actually ex
