China has done a great thing in Africa, 1,400 tons of garbage turned waste into treasure!

As a fast-growing African country, Ethiopia is moving rapidly from a backward country to a developing country. At the same time, it also encounters various

troubles that a developing country will inevitably encounter: a fast-growing city and a relatively backward country. The gap between the supporting service

facilities in the country has caused huge troubles for this country. In this regard, China has once again acted to turn at least 1,400 tons of waste produced by

Ethiopia into treasure, and turn it into electricity and other resources for the country. Very useful recyclable materials.


Because the waste-to-energy plant looks like burning waste, boiling water and then driving the steam turbine to drive the generator to run, but the boiler

structure of this power plant is actually much more complicated than ordinary coal-fired or oil-fired power plants: because Most of the garbage is highly

unstable in calorific value, and it cannot be a fuel resource that can be easily used by boilers like ordinary coal or liquid fuel.


As a mixture, the components in a pile of domestic garbage may be waste clothes that can be easily burned, or it may be waste plastic packaging that can

be ignited, but will generate a lot of toxic gas, and may even be mixed with Inflammable and explosive materials like discarded lithium batteries or heavy

metal wastes that cannot be burned at all. Therefore, before disposing of these garbage as fuel, Ethiopia must first inspire its citizens to carry out a garbage

sorting operation to ensure collection. The combustion efficiency of garbage returned as fuel can be guaranteed to a certain extent.


Secondly, the garbage must be matured before being incinerated, and the organic matter in it must be converted into flammable gas like methane as much

as possible to separate it for use as fuel. After the incineration process contains a large amount of toxic components and carcinogens, the furnace is discarded.

After a series of treatments such as alkaline washing and filtration, it can be discharged as harmless waste gas and waste water, so as to ensure that the

waste-to-energy plant can effectively clean up urban waste without causing secondary pollution to the local environment.


Therefore, the development and construction of waste-to-energy plants is not as easy to solve as it seems. If it weren’t for China’s support and Ethiopia’s own

strength, it would be impossible to develop and build a waste-to-energy plant with truly environmentally friendly characteristics. Although it is not too difficult

for Ethiopia to ignite and burn waste to generate electricity, how to ensure that all kinds of waste slag produced by power plants meet environmental protection

requirements and ensure that the exhaust gas from power plants does not poison local residents is the country itself. Ways to solve the problem.


Therefore, they will choose to build such a waste incineration power plant with the help of China to ensure that the residents' daily use of electricity is guaranteed,

while reducing the generation of garbage around as much as possible.
