The City of Philadelphia signed into law a new building code amendment requiring residential construction to include in-sink food waste disposals.
In a test conducted between 2012 and 2013, in-sink gargabe disposals were installed in 175 homes in two neighborhoods, which revealed the disposers reduce food waste by an average of 35%.
"The city concluded from that pilot that it could significantly reduce the city’s trash while improving the quality of life, by reducing odors and vermin," writes Allan Gerlat for Waste 360.
The movement to require in-sink garbage disposals is being debated across the country. Rep. Chellie Pingree of Maine is sponsoring a bill in Congress aimed to reduce food waste at both the consumer and commercial levels and encourage composting or waste-to-energy initiatives.
California started off the year with five new laws, involving mandatory commercial organics recycling, tax exemptions for recycling and composting equipment, detailing organics infrastructure, recycling and composting reporting requirements and composting promotion.
New York City is also looking into the possibility of requiring in-sink food disposals in certain multifamily districts.
