Different municipalities and companies have different guidelines for sorting and cleaning recycling materials before pickup. The tools and machines at the facility, as well as how they collect and process the materials, will dictate these standards.
Whatever the guidelines are, you need to follow them regularly if you want to minimize your own environmental impact and ensure that as much of your waste as possible actually gets recycled. Here are four reasons why it's important for consumers to follow the guidelines.
Recycling facilities have conveyor belts where the recycled materials slowly move past workers who have to pick out anything that doesn't belong. The more items that end up in the wrong waste stream, the more time employees have to spend sorting the recycling, which equates to a waste of resources.
In addition, misplaced items can further slow things down by getting jammed in the machines. Plastic bags, for example, can jam up machines, which wastes even more time. Some non-recyclable materials can even damage machinery.
Not only is not sorting items inefficient because workers have to sort that item out, but not sorting could result in items ending up in the wrong recycling room or even the wrong facility. Often, the recycling plant will simply regard misplaced items as contaminants and simply send them to the landfill. It's just too inefficient to collect them, resort them, and send them to the proper area for recycling.
In essence, your items often have one chance to end up in the right spot for recycling. If you're asked to collect plastics and paper items separately, putting something in the wrong bin can equate to sending it to the landfill.
If you have single-stream recycling, you don't need to separate papers from plastics, but you do need to be aware of just what the company accepts. If number 7 plastics aren't accepted, you may still be able to collect those and recycle them via a mail-in program. But sending them in with the recycling would just be giving them a ticket to the landfill.
