The article is full of "community" this and "local people" that, and very low on details. The little that is there raises red flags. For example: The fact that their rented machine shop had to close down is given as an explanation for them having to sell all their machines below cost and then not having the money to buy the machines back when they found a new place. That doesn't add up: temporary storage spaces exist and aren't even expensive, given that you can choose a remote location. It seems like a crucial detail was left out, maybe one that would paint them in a bad light.
I gather that they sell (apparently unsafe?) wood chippers, presses and some injection moulds, probably at cost. I don't understand what else is there. The "version 4" release thing mentioned in the article might be their open-source "academy" [1, 2] that's supposed to teach you how to start your local recycling shop. It includes valuable tips like "add all your expenses" and "don't forget to include taxes" and comes complete with an empty Excel sheet -- I'm sorry, a "Business Calculator". No commits since 2020, so the "version 5" of this guide that they claim to have been working on for five years must be hosted somewhere on a private GitHub fork instead. I'm sure it's awesome. Best of luck.
