www.food-waste-disposer.org.uk THE SCIENCE Page 1 of 6 There have been numerous independent scientific studies across the globe that have proven that food waste disposers (FWDs) play an important role in solving the food waste management challenge. This page gives a summary of 15 years of findings… United Kingdom 2012 – STRONG BODY OF EVIDENCE Recent report by Local Government Association (LGA) reviewed 147 pieces of literature available on food waste disposers (FWDs) in preparation for their forthcoming pilot study that will investigate the effects of domestic FWD usage in newly built homes. Out of 95 pieces of relevant research they found 60 that reported a positive impact from the use of FWDs. There were 23 pieces of primary research that concluded FWDs have a positive impact on the environment and do not have a negative impact on the sewers or waste water treatment plants. Key findings relating to the sewer network were: most studies found there to be no clogging; evidence on sewage settlement indicated sewage with ground solids may ‘settle better’; anaerobic evidence pointed to increase in biogas production and enhancement of biological nutrient removal; and data on residual waste saw a fall in volume of the general refuse stream.
