Some snippets from the below linked article: One reason for the can shortage: “California’s creaking recycling system can’t collect enough cans, one consequence of a program that has been crippled by redemption center closures and out-of-date policies that have made it harder for people to recycle effectively.” And: “The chronic shortage highlights how an overlooked link in the supply chain — trash — can hamstring a beloved, and booming, industry. About 73% of an aluminum can comes from recycled scrap. As demand for canned beverages boomed in recent years, the state’s patchwork of recycling centers and recovery facilities just couldn’t keep pace. In the last five years, California’s recycling rate for aluminum cans has fallen 20%, from 91% in 2016 to 73% in 2021, according to data from the California Department of Resources Recycling and Recovery, or CalRecycle.” Also: “In 2015, there were 2,245 buyback centers, or places where consumers could go to claim their nickel deposit on a bottle or can in the California Refund Value program. Those centers make their money by selling aluminum — as well as paper, glass and some plastic — on the scrap market. The price of scrap metals caved that year, falling 30.8%, and the centers began to close en masse. Some 420 centers couldn’t pay their bills and closed. An additional 600 shuttered during the next five years. CalRecycle, the state agency in charge, did little to stem the tide, according to critics.” https://www.yahoo.com/finance/news/brewers-cans-californias-broken-recycling-120055216.html Cheers!
