A Solarpunk-compatible use of AI: using AI powered robots to fix the problem of sorting of recyclable materials from our waste stream

A Solarpunk-compatible use of AI: using AI powered robots to fix the problem of sorting of recyclable materials from our waste stream

To reduce our impact on the earth, the correct order of priority is to reduce waste, reuse what we can, and then recycle. Washing and reusing a water bottle or a grocery bag will always be less energy intensive and less wasteful than melting it down / shredding it down to pulp to re-make another bottle or bag. But as long as we will have some form of waste, the problem of making recycling cost effective and thorough will be with us. One of the biggest problems facing the task of recycling is to correctly sort all the recyclables out of our trash, into their respective categories.

Sorting through waste is tedious and error prone drudgery, and is relatively low value work. Enough people are not conscientious about sorting their trash that we end up with recyclables in our trash and trash contaminating our recyclables. This is the perfect kind of job to automate with AI. This doesn't require massive resource-draining data centers; this just requires localized trained machine vision systems. It is also the kind of drudgery that people typically don't want to do if it were not paying sufficiently. I doubt any child dreams of being a trash sorter when they grow up.

With AI powered robots sorting through our trash, rates of recycling loss and rates of contamination (that can ruin entire batches of material at worst or lower the quality of recycled materials at best) can be reduced as low as possible.

IMHO, this is the sort of AI that should have been prioritized. Somehow we had to wait for this while AI ruined so many other things with catastrophic developments nobody was really asking for.

What did the confused tourist say when he exchanged currency for an unknown exchange rate while visiting Seoul?

“I have won, but at what cost?”

I saw this in an elevator in Emeryville CA in a new building that was built this past year. I don't know if that makes a difference. The elevator has a pair of buttons that seem to indicate "open door" and another pair that seem to indicate "close door", but the pair on the left have a vertical bar between the arrows, and the pair on the right do not.

I've pushed the buttons, and maybe I'm not astute enough to notice some subtle difference in function, but as far as I can tell, they just open and close the elevator doors.

What is the vertical bar between the arrows supposed to indicate? Is one supposed to close the door harder or more emphatically?

Just wrapped Day Zero Festival 2026 in Bali. Thought this community might appreciate the numbers.

The setup: 60 dry-composting wooden toilets. No plumbing. No chemicals. No water connection whatsoever. Just the toilet, local Balinese sawdust (0.5 kg added after each use), and a sealed container underneath.

What came out the other side:

  • 36,000 total uses across the festival
  • 18,000 kg of compost produced
  • 0 litres of water used (standard flush would have used 216,000–360,000 litres for the same number of uses)
  • ~27 tonnes CO2e avoided vs. chemical toilets — equivalent to about 1,240 mature trees working for a year

The compost goes straight to our flower farm. The flowers grown from it get gifted back to festival guests at the next event. The loop closes completely.

Sawdust sourced from local Balinese woodworking workshops — material that would otherwise be discarded.

I'm the founder of the company (Ecoranah, based in Bali) so obviously I'm biased — but happy to answer any questions about the system, the composting process, how we handle pathogens, logistics, anything.
