A national study by MIT researchers provides one of the first in-depth looks at the characteristics of places that have adopted food recycling, revealing several new facts in the process. For instance: The places deploying food-scrap recycling programs are located throughout the country, not just in well-off coastal areas with popular environmental movements. Significantly, cities with food-scrap recycling often have “pay as you throw” garbage collection policies (PAYT), which typically charge residents for exceeding a certain volume of trash. These programs make people more active participants in waste collection by having them limit and sort garbage. Thus, adopting PAYT paves the way for food-scrap recycling.
