Development of a protocol for practical trials of food waste disposers - WR1308

Project WR1308 forms part of project WR1301, which is an overarching programme of research on food waste disposal. The programme is investigating the use of FWD units to discharge food waste to sewers, where it could be co-treated with domestic sewage.

The UK produces an estimated 6.7 million tonnes of food waste annually and historically most of this has been collected together with municipal solid waste (MSW) for disposal to landfill. Meeting EU landfill reduction targets has prompted significant changes to the practices for collection, treatment and disposal of MSW and separate collection of food waste with treatment in dedicated composting and/or digestion facilities is an emerging approach.

In aiming to meet landfill targets, the diversion of food waste to sewer for co-treatment with domestic sewage is an approach which needs to be investigated to determine viability and sustainability, taking into consideration that significant investment in the existing infrastructure could be required to increase capacity. Defra needs to investigate the options for food waste disposal in order to balance the needs of sustainable waste management with potential impacts on the environment and the waste water treatment system. This will include assessing the financial and environmental costs and implications of the different options.

Project WR1308 will develop a protocol for local authorities and water companies to assess the environmental impact of using FWD to dispose of food waste to sewers in their area. The protocol will identify all measurements and records required, how these should be achieved and set minimum levels of accuracy required to ensure a successful outcome for a trial.
