Food Waste Disposers (FWDs) are units used by householders or commercial food operators to dispose of organic kitchen waste down the sinkhole to the sewer system.
FWDS are easy to install to a premise’s water outlet and can be retrofitted in buildings.
Powered electronically, the units contain spinning metal plates to grind the food into particles varying in size from 2 mm to 50 mm on average.
Currently, over one-third of waste generated from households and almost half of waste generated from the commercial sector (in particular, food service establishments) in Ireland is organic.
The policy for organic waste management in Ireland is to implement source-separate collection of this waste. FWDs transfer the management and treatment of organic waste from the solid waste stream to the wastewater system.
Food wastes disposed of to sewer by FWDs have to be treated at a wastewater treatment plant (WWTP) rather than composted at home or collected separately and treated biologically.
There are no FWD manufacturers based in Ireland, so these units are imported into the country. To estimate the number of domestic and commercial FWDs that may currently be in use in Ireland, importation data was sourced and examined.
A classification code for domestic FWDs was identified through Customs and Excise data and, using this code, the Trade Section of
the Central Statistics Office (CSO) was able to determine the number of these units imported to Ireland since 1992.
It was not possible to determine this information for commercial FWDs. Typical urban wastewater characteristics were used to determine the potential estimated loading of suspended solids at Irish WWTPs.
