There are 3 basic types of MRFs: Single-Stream MRFs take commingled
materials like paper and plastics. These were developed to make it easier for the public to recycle and increase public participation.
Dual-stream MRFs are where paper goods are brought in separated from glass, tin cans and plastics. In general, dual-stream MRFs can produce cleaner end-products. Because pre-sorting is done at home, and citizens are more involved, there are fewer contaminates.
