Garbage is a problem in big cities around the world . Particularly in Indonesia such as large amounts of waste in the streets . Not to mention the conflict between the government and citizens , which are located into landfills.
In developed countries such as Denmark
, Switzerland, USA and France . They have to maximize the sewage treatment
process . Not only conquer the stench, but has changed the garbage into
electrical energy . Specifically in Denmark 54 % of the waste is converted into
electrical energy .
Processing to change garbage into an
energy is easy , here's how to change it :
1. Garbage burned to produce heat (
thermal conversion process )
2. Heat from the combustion is used to
convert water into steam with the help of the boiler
3. The high-pressure steam is used to
rotate the turbine blades
4. The turbine connected to a
generator with the help of the shaft
5. The generator generates electricity
and the electricity goes to the houses or to the factory .
Thermal
Conversion Process
Thermal conversion process can be
accomplished in several ways , namely incineration , pyrolysis , and
gasification . Incineration is essentially the process of oxidation of organic
materials into inorganic materials . The process itself is a rapid oxidation
reaction between the organic material with oxygen .
Garbage from garbage trucks unloaded
and moved to inserator . In inserator the garbage is burned . The heat
generated from the combustion is used to convert water into high pressure steam
. Steam from the boiler directly to the turbine .
