Heating with pellets, heat of the earth, the garbage waste and crematoria - Here's a she, Sweden
Do not be put off by such a title, it's not as scary as it seems at first glance. Pellets, it is just compacted sawdust. Most towns in Sweden are heated this way. Of course, there are still found homes with wood, coal and fuel, but they are getting smaller. The Swedes are very sensitive to the environment and wasting trees so spoil the air for them too painful. In addition, there is the principle of the two "E" - ecology and economy. Not only do you need to protect nature, so also want to use the least expensive way of heating.
Therefore, it is thought up the engineering systems "heat hot" or "warm land". Both systems are based on the accumulation of land and mountain rocks solar energy. In the first case, the energy produced by breaking through the well to the ground water, the movement of which stone hole causes heating. In the second case, a layer of soil freezing, by which the long hose is laid with the circulating liquid (ethyl alcohol). Ground heat brings home the Swedes heat up to 20 degrees.
Sweden is also famous for the fact that there is almost no waste. All waste recycling are like, and often more than once. Something that can not be recycled - incinerated. And there is some warmth to their homes, mostly in high-rise buildings. But here there was one problem - the country is so fascinated by separate collection, that it was sorely lacking. At the government level there has been talk about the purchase of garbage in neighboring countries.
But the story of the crematorium, to be honest, a little surprised me. Indeed, in August 2019 the leadership of the city crematorium Vestenfors announced that will now heat the local school. The principle of the two "E" also applies here. But all the same, from the latest news to me as it is not on its own. And how do you feel about such an economical ecology?
