Recycling Plants Start Installing Trash-Spotting AI Systems (yahoo.com) 60
The world's biggest builder of recycling plants has teamed with a startup to install AI-powered systems for sorting recycling, reports the Washington Post. And now over the next few years, "The companies plan to retrofit thousands of recycling facilities around the world with computers that can analyze and identify every item that passes through a waste plant, they said Wednesday."
"[S]orted" recyclables, particularly plastic, wind up contaminated with other forms of trash, according to Lokendra Pal, a professor of sustainable materials engineering at North Carolina State University... [W]aste plants don't catch everything. [AI startup] Greyparrot has already installed over 100 of its AI trash spotters in about 50 sorting facilities around the world, and [co-founder Ambarish] Mitra said as much as 30 percent of potentially recyclable material winds up getting lumped in with the trash that's headed for the landfill. Failing to recycle means companies have to make more things from scratch, including a lot of plastic from fossil fuels. Also, more waste ends up in landfills and incinerators, which belch greenhouse gases into the atmosphere and pollute their surroundings.
Mitra said putting Greyparrot's AI tools in thousands of waste plants around the world can raise the percentage of glass, plastic, metal and paper that makes it to recycling facilities. "If we can move the needle by even 5 to 10 percent, that would be a phenomenal outcome on a planetary basis for greenhouse gas emissions and environmental impact," he said. Cutting contamination would make recycled materials more valuable and raise the chances that companies would use them to make new products, according to Reck. "If the AI and the robots potentially helped to increase the quality of the recycling stream, that's huge," she said...
Greyparrot's device is, basically, a set of visual and infrared cameras hooked up to a computer, which monitors trash as it passes by on a conveyor belt and labels it under 70 categories, from loose bottle caps (not recyclable!) to books (sometimes recyclable!) to aluminum cans (recyclable!). Waste plants could connect these AI systems to sorting robots to help them separate trash from recyclables more accurately. They could also use the AI as a quality control system to measure how well they're sorting trash from recyclables. That could help plant managers tinker with their assembly lines to recover more recyclables, or verify that a bundle of recyclables is free of contaminants, which would allow them to sell for a higher price.
GreyParrot's co-founder said their trash-spotting computers "could one day help regulators crack down on companies that produce tsunamis of non-recyclable packaging," according to the article.
"The AI systems are so accurate, he said, that they can identify the brands on individual items. 'There could be insights that make them more accountable for ... the commitments they made to the public or to shareholders,' he said."
