Recycling
Where does your recycling go after you throw it away?
Recycling from individual bins across campus are collected and emptied into the compactor.
When the compactor is full, Recology picks it up, dumps them at their Materials Recovery Facility (MRF) in the Industrial District, and returns them to campus.
The recycling is sorted at the MRF depending on its material make up.
First, the product is sorted on giant rollers, separating out paper, cardboard, and glass from the rest.
Paper and cardboard are light so they float to the top of the rollers,
Glass is the heaviest and falls to the bottom of the rollers,
Plastic and aluminum make up a majority of the remaining products.
Glass is added to a large, spinning drum that removes dust, paper scraps, and other light materials.
Plastic products are hand-sorted. #2 plastics are separated out and an optical sorter further separates plastics by their numerical type.
Metal products, excluding aluminum, are sorted using a magnet.
Aluminum is extracted using an Eddy current separator which temporarily magnetizes aluminum, making it easy to sort.
Once sorted, the materials are redistributed across the globe to be repurposed.
Glass products stay local due to its weight. Strategic Materialstakes most of Recology’s glass product and uses it to make wine bottles for local wineries.
Aluminum is shipped to Anheuser-Busch in Texas where it is reprocessed into new cans. Often an aluminum can can go from the recycling bin to the MRF to a grocery store shelf within 90 days!
Some plastic, paper, and cardboard wastes stay in the United States forremanufacturing, while others are shipped internationally to be made into new products.
For example, Green Toys turns plastic milk jugs into 100% recycled toys for kids! Learn more about their process.
