In order to keep the power consumption very low and maintaining a high torque we chose a stepper motor with a planetary gear. We are happy to share detailed information upon request.

We developed this workspace in cooperation with Mojo Fullscale Studio and with support of Sei So Frei and fair Styria from Austria. We are working with a manual shredder and an injection machine developed and produced by plasticpreneur, also from Austria. Recently we developed an innovative electrical shredder, operated by solar power. We are producing small goods for the local market for affordable price. So far we are able to produce: abacus, rulers, spinners, hooks, bowls, cups, plates, tiles, clothing pegs, carabiners, buttons, shovels and pearls. This project gives underprivileged people a chance to gain practical skills and an income. We are steadily training our staff and building up their abilities to develop and strengthen this project for the goal of a clean environment and a local generated value – out of waste!
