Our needs are small:
Some used IBC tanks with intact lids. A drill with appropriately sized hole saws. Plumbing materials (pipes, valves, elbows, Ts and fittings). Black paint. Insulation materials. Gravel or stones. About 100 kg of some kind of animal manure as a starter inoculant to introduce the microbes. That's it. We've done this in remote villages in Africa and in the streets of Istanbul and everywhere in between. This ain't rocket science; we just need it to take off!
Do you need CNC machines, 3D Printers, wood, metal, tape etc.?
