📘 How does recycling actually work?
You drop the bottle in the blue bin and walk away feeling finished. You just started a shipment — not a recycling. EPA's definition is industrial, not moral: collect the thing, sort it, process it into a raw material, remanufacture that ma
What you’ll learn
- The bin is not the factorySeparate putting something in the bin from EPA's industrial definition of recycling, using the 2018 national numbers.Collection is not recycling. EPA's 32.1 percent is recycling plus composting. Recycling alone is about 24 percent, half of MSW is landfilled, and most recycled tons are paper.
- Collection is a productTreat single-stream, dual-stream, and deposit-return as collection designs, and treat contamination as a mill problem.The truck is a product. Bags, batteries, and food wreck bales. Your town's list is a list of current buyers.
- Materials are not equalCompare 2018 EPA rates for batteries, boxes, cans, glass, PET bottles, and all plastics.Lead-acid batteries and cardboard loop. Aluminum cans sit near 50 percent. All plastics sit at 8.7 percent because most plastic is not a bottle.
- The triangle is a resinRead a resin identification code as a plastic name, not a pickup promise.EPA and ASTM: the number is not recyclability. 2013 swapped arrows for a solid triangle. Bags and many 3-7 items need a different door.
- A mill has to want itFollow EPA's sequence through a mill sale, National Sword, the hierarchy, and a local-list check tonight.Recycling ends when someone buys the new product. China left as the buyer of last resort in 2018. Reduce sits above recycle. Check the hauler, not the arrows.
Questions this course answers
When you put a bottle in the recycling bin, what has usually happened?
EPA defines recycling as collection, sorting and processing, remanufacture into new products, and purchase of those products. The bin is the first step.
Match each 2018 EPA recycling rate.
The plastics average is low because most plastic is not a PET or HDPE bottle. Cans sit much higher because the metal is valuable to remelt.
Order EPA's recycling sequence.
Without the last purchase, the earlier steps are inventory. EPA names consumers buying recycled-content goods as the last link.
