Can Robots Solve America's Recycling Crisis? (cnbc.com) 148

Posted by EditorDavid from the robo-recycler dept.
CNBC reports that to solve America's recycling crisis, "companies and municipalities are turning to AI-assisted robots." The problem began last year when China, the world's largest recyclable processor, stopped accepting most American scrap plastic and cardboard due to contamination problems, and a glut of plastics overwhelming its own processing facilities. Historically, China recycled the bulk of U.S. waste... The situation is dire for many local economies as recycling costs skyrocket. It's forced many cities and some small communities to stop recycling all together. Now more waste is ending up in landfills and incinerators.

To tackle this environmental catastrophe, U.S. companies and researchers are developing AI-assisted robotic technology that can work with humans in processing plants and improve quality control. The goal is to have robots do a better job at sorting garbage and reduce the contamination and health hazards human workers face in recycling plants every day. Sorting trash is a dirty and dangerous job. Recycling workers are more than twice as likely as other workers to be injured on the job, according to a report at the University of Illinois School of Public Health. The profession also has high fatality rates.

The way the robots work is simple. Guided by cameras and computer systems trained to recognize specific objects, the robots' arms glide over moving conveyor belts until they reach their target. Oversized tongs or fingers with sensors that are attached to the arms snag cans, glass, plastic containers, and other recyclable items out of the rubbish and place them into nearby bins. The robots -- most of which have come online only within the past year -- are assisting human workers and can work up to twice as fast.

    Yes, robots absolutely could enable better recycling. However, no, they won't solve our short-term crisis because of the investment cost. This said, the current situational change ("crisis") is just a hiccup compared to the real problem. The real problem is that it doesn't cost much money to just throw things away and there is entirely no penalty for making products that are difficult to recycle. Eventually, humanity will be forced to face this fact and either start charging companies the cost of recycling or heavily subsidize it.

    The other possibilities is we create recycling that is less costly than using new material (unlikely/very far off/100% automation), there is an enormous culture shift that changes corporations (exceptionally unlikely) or humanity goes extinct (maybe).

        The problem with plastics - the hard part - is that there's not just one substance known as "plastic". There's numerous different kinds in consumer products, which cannot be recycled together (and some can't be recycled at all). Many times there will even be multiple types of plastic used in a consumer product (for example, water bottles made out of PET with polypropylene caps and rings). There's no way you're going to teach consumers how to sort different types of plastics from one another.

Aluminium is the most energy intensive raw material to mine and process. Which is why we have always recycled Al cans. Other materials take less energy to mine and process than recycling needs quite often. When it doesn't, recycling has a chance but the energy needed to sort and separate out the desired materi

    Specifically, how to recover valuable elements left over from the ~5% of mixed, unprocessable waste that even a good recycling plant will leave behind. I was thinking a resurrection of the old peroxydisulfuric acid (Marshall's Acid) process for electrolytic hydrogen peroxide production that was replaced by the anthraquinone process. You have Marshall's acid, converting to piranha solution - an intensely aggressive oxidizer of organics, to the point that it will even break down soot / graphitic carbon, eliminating essentially all organics except fluorocarbons. Non-noble metals would be dissolved and deposited at the cathodes (selective electrodeposition isolating individual metals) in the electrolytic cell that generate the peroxydisulfuric acid. The remaining waste should be noble metals, fluorinated hydrocarbons, ceramics, glasses, and other resistant oxides. Noble metals could be extracted by a followup bath a similarly regenerated hot HCl + H2O2 bath, HNO3 (limited concentration) + H2O2, or aqua regia. Smelting or simple high temperature incineration of the tailings should yield fluorine recovery in the flue gases.

    It wouldn't be an efficient way to deal with bulk waste, but for difficult waste streams... I don't know, just something I've been idly thinking about.

    The long-term, permanent solution is to prevent the waste from being created in the first place. Find replacements for all this plastic, something that either can be recycled easier, or that degrades safely into something non-toxic (preferably good for the soil) in a landfill.

      But it is all doable. The more difficult thing is likely to be rejecting dirty items. Or more realistically, identifying the small percent of items that are clean.

          For glass and metal recycling it is less problematic, because they're processed at high temperatures anyways.

    So when I was in school, the mantra was "Reduce, Reuse, Recycle." The words were in that order for a reason, but everyone focused on the "Recycle" part which doesn't really solve the problem all on its own. Reduce the amount of material you use (and thus trash you generate). Reuse as much of the material as you can yourself; jars, bottles, bags, boxes, packing material, and so on. Recycle as much of what's left as you can.

    I think another PSA campaign to reintroduce and push this concept would be a very good thing.

    On top of that, some consumer education on exactly what contamination is in (terms of recycling) and how to avoid it would also be helpful. Really simple things like not putting plastic bags in the recycling - "but they're plastic! You recycle plastic!" - Nope, plastic bags and films are not recyclable! They just clog up the machines and need to be removed by workers.

    I think there's enough people who care to make a difference, but they just need to be reminded what to do.
