The municipality of Rüti operates a wastewater treatment plant (WWTP) in Gruebensteg for about 14,500 inhabitants (approx. 16,750 population equivalents, including industry and commerce). The municipalities involved are Dürnten, with the village part Tann (2,650 PE) and Bubikon, area Kämmoos-Egelsee (350 PE).
In rainy weather, up to 250 l/sec of wastewater can be fed to the WWTP. Larger quantities are retained in stormwater tanks and later fed to the WWTP. After the 3-stage, i.e. mechanical-biological-chemical treatment, the wastewater is discharged into the Jona. Every year, about 11,500 m3 of digested sludge is dewatered and sent for incineration. The digester gas produced is processed in a combined heat and power plant and the electrical energy generated, approx. 250,000 kWh per year, is fed into the Rüti public utility grid. The waste heat is used to heat the digester rooms and the plant operation.
The WWTP was expanded between 1989 and 1994 and has been adapted to the new regulations to date. In the future, too, adjustments and renovations will be necessary on an ongoing basis due to new findings. Current planning goes up to 2020 and expects a load of up to 20,000 PE.

Nils and I wanted to find out how long you need to run at a constant speed to produce enough energy to bake a cake.
We've found out that a human being is able to produce 80 Watt hours, if he trains one hour on the dreadmill.
To bake a cake for 20 minutes the oven needs 950 Watt. So we calculated the number of hours you need to run.
Energy wood is the most important renewable energy source in Switzerland. Unlike oil, gas and coal, the combustion of wood as firewood, pellets or wood chips takes place in a CO2-neutral cycle. The carbon dioxide released during combustion is reabsorbed by the renewable forest.
Burning wood as firewood can probably be considered the oldest use of wood. Worldwide, the use of the forest as a supplier of firewood still ranks first. In Switzerland, too, energy wood is experiencing a renaissance. After hydropower, biomass is the most important regenerative energy source in Switzerland. Wood is by far the most important biofuel. In Switzerland firewood is burned in almost 1.8 million stoves.
Why should you heat with wood?
Wood accumulates in sufficient quantities during forest management and is constantly growing back on our doorstep.
Quiz
How many litres are being saved per year?
• 100 Mio.
• 5 Mrd.
• 2 Mrd.
• 50 Mrd.
Biomass
Discarded orange peels, cow dung or wood - there is valuable energy in numerous organic wastes and in forest and residual wood, so-called biomass. Among renewable energy, biomass is considered the all-rounder: it can be used to produce electricity, heat and fuel.
Carmen R. / D. and Jana
This project idea made us think a lot about our environment and how easy it sometimes is to make an impact or to try it like our parish kind of does. We really hope that using bicycles is going to be a topic we’ll talk more often about in the future. Also we’ve decided to use our bicycles more often in our free time and we even started to go to work with them sometimes.
Our Project : Cycling for a better environment
Introduction
Our environment is in great danger and it is getting worse and More...
Our next step will be to collect some pictures and maybe take some on our own, if possible.
XOXO
We asked our community for documents concerning the cycling project and they’ve sent us some documents and now we just uploaded the draft onto dontwastemyenergy.
XOXO
So the next thing we are going to do is talking to our community about our project idea. Because Carmen is working for our community she is going to ask them, if there are some documents we could use for our project. Furthermore she is going to find out a little bit more about the planned project, which they‘ve had in mind.
Gracias!
Cycling for a better environment
Cycling is something that most people are able to do. Most people are able to ride a bike from a very young age and most of us aren’t too bad at it. So why not do it more often? It’s not just good for your health, but also for our environment. That is why we want to start this project and encourage people to use there bikes more often. We want to start with building new paths, new options for your bike tours and more options for your safety on the streets. Start now and help us to turn our idea into a project.

Concept:
Our concept is to pretty much cooperate with different people of our hometown, because this is going to be one of the main points of our project. We want to do surveys with pedestrians and also talk with our parrish. We want to compare the surveys we do with the articles we find about our project idea on the internet.
Time plan (still in progress)
Imagination
We hope that with this project, that there will be some kind of change in the near future and that we all think about more economical transport options like using our bikes more often.
