Food waste in the United Kingdom 46% increase in biogas. Food waste remains primarily disposed to landfill (54 per cent of total municipal waste was disposed of in this way in 2007/8), although year-on-year the amount being sent to landfill is decreasing. Composting, the purposeful biodegradation of organic matter by microorganisms, is among the most simple ways of treating food waste and thereby preventing it being sent to landfill. Since all biodegradable materials will eventually oxidise to become compost, the process can be undertaken at home with no running costs, although equipment can accelerate the process. Most components of food waste are putrescibles and will be
