Collection Models Best Practices
-
Most single-stream recycling programs include glass bottles and jars along with all recyclables mixed in a cart or bin. This is currently the most preferred method to provide the environmentally-friendly and convenient glass recycling access to residents. However, in this collection model the quality of glass can suffer due to breakage from compaction which causes contamination with other materials.
-
Residents still have the convenience of a curbside cart for their traditional commingled recyclables with a separate bin for their glass recyclables. This enables residents to have curbside access while keeping single-stream items free of potential contamination from broken glass. This also allows glass to be recoverable at a higher rate.
-
Dual-stream programs will often feature two bins or carts one for fibers (paper, paper board, mixed paper and cardboard) and another for containers to include plastic bottles and containers, metal or aluminum cans and trays, and three colors of glass bottles and jars. This is effective in reducing glass contamination to paper products. Higher compaction of the materials could lead to greater loss of recoverable glass.
-
Many communities already have drop-off centers for all recyclables providing containers for single-stream, dual-stream or source-separated material. These centers offer an option for multi-family communities and businesses without recycling collection drop-off recyclables. In these centers, glass could be collected commingled with other recyclables or separated by color or mixed colors. Check with your end user for best collection options.
Note about drop-off programs: Without the convenience of curbside collection, some glass bottles and containers may still end up in the curbside recycling or worse, the trash can.
-
Some communities have opted to keep glass in their program through a drop-off only program exclusively for glass. These programs are successful at collecting glass from motivated glass recyclers and should be offered as an alternative to removing glass all together. Consider placing glass collection containers where glass is purchased, liquor and grocery stores.
