In the previous post I did not discuss particular technologies to purify waste water and to turn it into clean water. One way to remove minerals from waste water are algae.
As orbital space settlements will get most of the energy from solar power, there is little use for biofuel. However, algae have a lot of other useful applications. Continue reading Sewage and Algae
Sewers are the summit of human civilization and taxation is the price of civilization. So we are supposed to pay sewer tax, right? No, not really. In this post I will explain how space settlements could fund a sewage and waste water treatment system without having to collect sewer charges. Continue reading Sewers and Taxes
Here another use of a fungal materials. Ecomotive is using organic waste and fungi to make a bio-degradable alternative for plastic packaging materials.

Previously we discussed the concept of barter shops. In this we will look to develop the basic idea even further. Continue reading Barter shops 2
In waste management people often talk about the “three Rs”: reduce, reuse and recycle. The second “R”, reuse, refers to the fact that much “waste” consists of things that is still usable, but is nevertheless thrown away because the owner does not need it any longer. Reuse seeks to find new users for goods which are not broken. Continue reading Barter shops
Around the world underground waste containers are an increasingly common feature of the street scene. These containers allow people to dispose of their domestic waste when needed rather than having to wait for the garbage truck. Continue reading Waste collection in space settlements
Many years ago the city where I lived at that time, had a nice initiative: a recycle bank. People could earn and save money by “depositing” trash. There were three categories of trash which could be turned in: paper/cardboard, plastic and textile. Each category had its own price. Continue reading Trash for Cash
In many civilized countries households pay a fee for funding the public waste disposal service. This system, however, stems from the age when garbage was dumped at landfills and waste was considered as a valueless annoyance. 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. Continue reading Should households pay for waste disposal?
In space settlements recycling will be an essential part of their waste management system. In case of durable consumer goods, such a washing machines and refrigerators, we advocate a system in which these goods are leased rather than purchased. And at the end of the lease term or end of life time, the goods are returned to the manufacturer for recycling. Continue reading Recyclable clothing
One of the most important issues in any given human society, is the management of its waste disposal. And space settlements will be no exception. 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.
