An innovative program in Melbourne, Australia is tackling greenhouse gas emissions associated with food waste while cleaning up popular restaurant areas. The 90 businesses in the well-known Degraves street area are switching from compost-only to a food recycling program that dehydrates food waste and turns it into fertilizer. The fertilizer is then used in local parks as well as farm in the surrounding area.
Invented in Korea, this process of dehydrating food waste results in less methane and CO2 emissions than standard composting. The smell that the dehydrating produces is much less imposing than composting food, which will be appreciated by the restaurants who currently compost outside of their buildings.
The city hopes to install similar dehydration machines in apartment buildings, which may encourage residents to recycle more of their food waste scraps.
