Philadelphia recently introduced its green garbage disposal pilot program to residents of the city in an effort to reduce the trash stream in the city by 10 percent.

Emerson, a Wisconsin-based company famous for making the InSinkerator, donated 200 units of the new disposals to apartment buildings in West Oak Lane and Point Breeze, according to CBS Philly. The aim is to test out the program and see how much of an effect it has on the city's conservation efforts.

“We’re going to install a couple of hundred of them for free, in two specific garbage truck routes, so that the city could do a test to see how much good we could accomplish keeping food out of garbage trucks and out of landfills,” said David MacNair, spokesman for the InSinkerator company, according to the news source.

Philadelphia's goal is to convert trash into green energy and fertilizer after it's processed by wastewater treatment plants, CBS Philly stated. According to Carlton Williams, deputy streets commissioner, close to 40 percent of Philadelphia households already have food waste disposers.

Springfield, Illinois, is also looking at different ways it can cut down on the stream of trash in the city, altering recycling-oriented services and designating specified days for yard waste and garbage pickup, according to local news source the State Journal-Register.
