British supermarket chain, Waitrose, which was named the most environment-friendly store in 2006 by the U.K.’s National Consumer Council, continues to impress the environmentalists with its green grocery practices. In its latest eco-friendly initiative, the company has decided to operate delivery trucks entirely powered by gas produced from rotting vegetable matter and food scraps.
Waitrose, which has collaborated with C.N.G. Fuels, a supplier of renewable biomethane gas, will also be a beneficiary of this fuel switch, reports Martha Stewart. The delivery trucks mileage almost doubles when powered by biomethane gas and also, this biofuel costs 35-40 percent less besides reducing carbon emissions by 70 percent.
Two factors that have kept the companies reluctant in switching to biomethane-powered trucks are the high cost of such modified vehicles and the scarcity of refueling stations, notes Seeker. However, improved mileage combined with more refueling stations and better pipeline infrastructure, have made these trucks genuinely competitive, pushing higher demands recently.
