Alison Austin, Sainsbury's environment manager, above, said: "This move underlines our commitment to the Scottish Government's zero waste ambition. "Each tonne of food waste diverted from landfill by Sainsbury's will generate enough power for 500 homes and will save three tonnes of CO2 compared to fossil fuels. "Scotland is at the forefront of our wider UK plan to completely cut our dependence on landfill. This is the first step in a plan that will see Sainsbury's stop using landfill for food waste by this Summer and stop using landfill completely by the end of the year. "Businesses throughout Scotland and the rest of the UK need to demonstrate their commitment to finding workable, commercially sound solutions to today's environmental problems." "The plan that we have developed will not only substantially reduce our landfill usage in Scotland, it will also cut our CO2 emissions as we will be putting far fewer trucks on the road."
