Renewable Energy has for many years installed composting toilets in Denmark – despite of the nervousness and opposition of the Danish authorities.

Composting toilets remove the “black wastewater”, and safe the water for bad nutrient salts and reduce the use of our water resources.

The global perspective

In Denmark we can easily dig wastewater pipes in the underground. In our neighbor countries Norway, Sweden and Finland, they have the solid rocks under the houses and cities, why it has been so difficult to create all the drains and pipes to send everything mixed with water to the sewage plants. In Finland there are more than 400.000 toilets without water, here different types of composting / dry toilets is daily praxis for nearly 1 mill. People.

In India 70% of the population have no toilets (this is a special problem for the women, f.in. the girls cannot go to the school, if there is no toilet at the school). In USA MacDonald’s build composting toilet in the areas outside the public sewage systems. Also in the states there are a lot of home-build composting toilets. In Japan the universities have research teams lead by a professor in composting toilets. In Japan very many people live on little space and of course clean drinking water is a huge problem.

Many places in Africa the women spend the day walking hours and hours for water – at the same time the rich consumer consumes more and more water in their toilets.

At water flushing toilets has been a status symbol in the poor part of the world is absurd.

If you ever have stayed at a resort in Asia and seen how the coral reefs are spoiled by the water flushing toilets of the tourists, you might consider if you want to continue to flush water in your toilet, or rather be a good composter !

Underneath you see 2 pictures of a composting toilet building we build on a workshop in Kerala, India. There is an extra hole for washing water (no use of toiletpaper)
