Dutch Sewage Treatment Plants Produce Energy from Waste

It takes a lot of energy to turn sewage into potable water but the times are changing. In a new development, Dutch water treatment plants will start producing their own energy.

In Holland, at least 750 GWh of energy is used to treat sewage waste every year. This ammount of energy is comparable to the ammount that a city of a million people uses in a year. Of the 750 GWh, the sewage treatment plants produce only 150 GWh from the biogas produced in the internal treatment process. In the near future and with current technology all 750 GWh will be produced from the interal biogas produced. And this is only the beginning.

The ambition is that a sewage treatment plant that serves 100,000 people would produce not only the energy for the plant itself but for a further 225 households. This would mean that 36,000 households would be powered from waste treatment every year.

The website http://www.energiefabriek.com/ has produced a map of the energy that can be produced in this way.

Back in business

I'm back in the Blogging business. Let's see how long this time lasts.

Hmm. Let's start with a blog on one of the things that'll probably be filling up my blog a lot.

Introducing GIS!

A Geographic Information System (GIS) is a computerized system of containing geographic information. Quite often (and most often is the case) this means making informative maps.

Step one: The best known software system for GIS is made by ESRI. So here's a little film on ESRI's very popular product ArcGIS. http://www.esri.com/what-is-gis/index.html
