- rm_-rf_slash 10y agoI wonder how useful this technology could be to zero-sort recycling. As much of a hippie as I am, I don't think recycling can be solved by green bins and awareness campaigns, but instead by the simplicity of throwing everything into one bin that gets sorted when it reaches the processing plant. It would also be helpful if this could sort organic material for use in compost and sell it. Maybe even brand it. How much do you think people would pay to use compost from Beverly Hills celebrities in their garden?
- hanniabu 10y agoAll your organic material would be contaminated by toxic material by the time it gets to the plant. People throw out all sorts of things...leaking batteries, car oils and fluids, electronics, and even salts wouldn't be great when talking about using it as compost.
- blacksmith_tb 10y agoI suspect it could be useful for some types of recycling, but there are already a lot of tricks employed to separate dissimilar materials - metals and paper products sink, plastics float, field effect and or magnets can move metals, etc. Using CV to recognize materials would be overkill by comparison. But I find watching the bot sort soothing...
- jarvist 10y agoI believe WEEE (Waste Electrical and Electronic Equipment) recycling plants use computer vision directly. Recycling plans having multiple optical units with compressed air to then redirect the route of identified items, but I don't know whether this is image recognition or Raman / IR to identify the material. Certainly to differentiate plastics, it will be Raman / IR. An info vid on a recycling plant, showing the sort of scale and speed of sorting:- https://youtu.be/SIVKmwzWSuc?t=1m14s https://youtu.be/SIVKmwzWSuc?t=1m14s
- ZeroGravitas 10y agoThere's similar tech already in use. Sorting flakes of different plastics can be done by "vision" if you have different wavelengths of light, then tiny air blasts can direct them into the right hopper. Though, the more raw sorting that can be done the better for the system. Where I am, we put food waste in its own bin, and frankly it just seems natural after a very short time.
- jonnycowboy 10y agoAlso for berries, waves of berries are visually identified and blasts the "bad ones" out of the stream. Very impressive (and fast) to watch.
- wickawic 10y agoI can't find the video, but apparently at some canneries there used to be a person who would very rapidly hit the tops of cans with a metal rod and listen to the noise that it made. "Bad" cans sounded different and would be removed from the line. After years of practice these workers were inhumanly fast at the job.
- igravious 10y agoAnd dead inside.
- rtkwe 10y agoIt's used for a lot of food products like chips too.
- wlesieutre 10y agoNot berries, but here's the same sort of machine: https://youtu.be/7nTtjVFuY6M?t=47 https://youtu.be/7nTtjVFuY6M?t=47 Some false positives, but it's incredible how fast those can run.
- Animats 10y agoIf you haven't seen a high speed visual sorter, it's impressive.[1] It's economically feasible, and routine, to inspect each individual berry with cameras, lasers, and computers. Size, shape, and color are all checked. Some plants even look at every grain of rice. The items are sorted with air jets.

- tanker 10y agoI think the organic material idea is good, but not at a distant collection point. If you throw organic material away --> transport to site --> sort it --> delay --> transport to stores --> transport back to garden I think you lose the energy battle. If you created local dump sites where trash could be sorted and composted, it could work. You also cut down on the amount (and as a result the energy) of trash that gets thrown in the dump. Obvious obstacles are the inability to get people to use the local sites, the initial costs / availability of land, and the resistance to dumps in neighborhoods. A potential 2nd level effect would be the long term state of trash dumps. At least some dumps are eventually reclaimed. Would reducing or eliminating the organic content prevent that from happening?
- rm_-rf_slash 10y agoIt takes a lot of cultural engineering to get people to be that diligent. I'm from an ultra liberal college town and I'll never forget going away to college and spending 15 minutes looking for the compost bin in my freshman dorm. No dice. Then you have places like Florida, where nobody recycles. Trash is trash. Throw it away and take it to the curb. Even the most elegant and energy-efficient local dump system would go nowhere with a culture that would rather throw away and forget about it, and this is coming from a state that is most vulnerable to climate change yet is full of beach house-owning republicans who think climate change is a hoax.
- soperj 10y agoVery soon here they're not going to accept garbage with compostable material in it. It'll be interesting how big of a push back that gets, but there is definitely ways to make people feel a bit of pain for living a throwaway culture.
- mcculley 10y agoAs a Floridian, I'm curious how it works elsewhere. In what ways are systems in other places better? I live in Seminole County and we have recycling bins. It sounds like you think it should go further.

- TheSpiceIsLife 10y agoI need this to help me deal with this problem at work https://imgur.com/HM8euP8 https://imgur.com/HM8euP8 The laser cutter is capable of more product output than I have time to deal with sorting and stacking them on to pallets. There's another 400 parts behind me waiting to be broken free from their retaining tabs. Each item is etched with a part ID. Some sort of computer vision + robot should be able to do the job for me. I have the tools to put something like that together. Any leads?
- huuu 10y agoSometimes this can be done by simply trowing them in a funnel and let slots of different sizes sort them. Just like those coin sorting machines. But in your case a sorting conveyor belt could be the easiest way. The right items are pushed off the belt at the right time. Edit: an example: https://www.youtube.com/watch?v=Ajxs6_V8KJM https://www.youtube.com/watch?v=Ajxs6_V8KJM And by the way: if you got 50 unique items it doesn't mean you need 50 slots. You can also create 10 and repeat the process for the unsorted items. But you need to reprogram the system each run.

- justzisguyuknow 10y agoI forget where I heard it, but I recall a saying something along the lines of, "The two most meditative things a person can watch are fire, and other people working." I think this also kind of falls into that category. PS if anyone knows the actual source of this saying please do comment
- 11thEarlOfMar 10y agoDon't know the source, but as far as 'watching other people working', here are two of my favorites: https://www.youtube.com/watch?v=8VGjA66RSm0 https://www.youtube.com/watch?v=8VGjA66RSm0 https://www.youtube.com/watch?v=P73REgj-3UE https://www.youtube.com/watch?v=P73REgj-3UE
- twidlit 10y agoCrossing my fingers for a Lego sorting robot...
- bbcbasic 10y agoHa ha yes a kids toys and clothes sorting robot.
- donquichotte 10y agoAt first glance I read the title as "A Sock-Sorting Robot", something I'm totally going to build.
