I agree. Costing on the proposed model is one of the largest caveats as I pointed out in my first post. Determining whether a centralized or decentralized model is “greener” or just greenwashed is another. The third, but certainly not the least is who is the entrepreneur driving the development process.
And maybe the manufacturing processes are limited, but you can get a lot of things made without molding, it all starts with that initial design. Some designers will complain about limitations, but I for one would like the challenge.
