Recycling

A colony on Mars uses a number of materials to build everything they need for living. Mining is one way to acquire new materials - and a pretty laborious one.

A lot easier is the Recycling of litter, especially if the litter consists of only a few materials, and most easy if the pieces of litter are made from single material. The concept requires special manufacturing, that takes care to use pure single material if possible.

Things made from single material

• Bottles from glas
• Boxes from plastics (e.g. polyethylene)
• Tins from stainless steel
