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."

      It's the same reason Twitter couldn't implement a screening for white nationalist and Nazi comments like they did for ISIS. Republicans would be classified as well.

    Being able to have machines do an arduous, dangerous, disgusting task that most human beings really would not want to do on a large scale in a facility because too many humans can't be bothered to do it at the point of disposal is a perfectly acceptable use of AI to replace human labor.

    • Sure, until it costs $100 per pound of garbage.

      • Why would anyone make the capital investment of machines when they would cost more to operate than paying people? (assuming $100/lb is more expensive than people)

      • Okay, except that humans doing it costs a *vast* sum of money. Thatâ(TM)s the primary reason why almost no plastics are recycled.

      • Citation, please?

        This thing will never get distracted or tired of the tedium of accurately sorting the garbage. The economy of scale is going to be huge.
      • Why would it ever cost $100 per pound of garbage? That doesn't make any sense, and the article certainly doesn't state this.

        The whole point is to develop a system that is cheaper than human labor, not more expensive.

    • This is pretty much what AI is good for. Even the ChatGPT and Copilot varieties are all about doing arduous, repetitive work that regular humans don't want to do.

  • This is surely not the first time image recognition is used to run task pocket robots. Is this significantly better than existing systems, or is it just news because a startup says "AI"?

      Actually a large portion sorting systems rely on physical properties to separate trash. Also I assume you were trying to say "trash picking robots", for the most part trash processing facilities haven't used picking robots, rather they use conveyor systems with separation elements to it, think something as simple as a jet of air to separate light plastic bags or magnets for iron.

      I'm sure there are some plants with picking robots and I'm sure it's not the first time image analysis has been used, but it certa

Every nonzero finite dimensional inner product space has an orthonormal basis. It makes sense, when you don't think about it.
