SINGLE STREAM VS. SOURCE SEPARATED RECYCLING.

Most discussion and debate about respective merits and drawbacks of various collection methods, schedules and tools have been based on opinion and anecdotal evidence. Eureka Recycling, a nonprofit based in Saint Paul, Minnesota, took an empirical approach to checking the system of collecting recyclable materials in residential neighborhoods, with a 14-month study to determine the best method for the city to increase recovery and improve efficiency. The study done with the city of Saint Paul through a grant from the Minnesota Office of Environmental Assistance, compared five recycling collection methods, which varied by frequency, type of containers used, types of materials collected, and how materials were separated.
