Though many developed countries has switched to incineration as their primary method of waste disposal, waste was and is still seen as the useless by-product of consumption.

Of course space colonists could simply dump their waste into outer space, but this will be inefficient since this also means the loss of valuable resources. Waste management of space colonies should be based on reduce, reuse and recycling. In this post we will discuss several policies which could be implemented to achieve these 3 R’s.
