Methane Extraction from Househod Waste

Extraction Methane

We can make methane gas from our household waste like our pup, garbage, dry branches and leaves, and etc. Firstly, we must put the waste into one kind of tube that we called ‘warming bed’. After we put into the warming bed, the water will be fertilized and the residue from fertilization, which is methane source, will go to the dirt part. In the dirt part, the methane source will be divided into dirty methane gas and the garbage which is no longer contains methane. The garbage can be taken from ‘release cap’ in the bottom of dirt trap. Then, the dirty methane gas will go to ‘gas indicator’. This indicator contains water which will be given with dirty methane gas and then the liquid will be separated into dirty water and methane liquid. Because of the mass difference, the methane liquid in the top of the water and this liquid will flows and divide into two pipes. The first pipes bring the methane liquid into the ‘pressure release’ which contains water. The water in this tube will contain methane liquid and methane gas will be produced when the temperature rising to the methane‘s boil point. The other pipe will bring the methane liquid into the ‘gas holder’ which contain tap so methane liquid can flow.

Working Children

Nowadays, we can see many underage workers in our surrounding. We can see in the streets, and public facilities. Commonly, they work as lift laborer in the market, or as streets beggar.

Based on sheet from PUBH in 2005, there are 200000 working children have bad injury when do their work, from the entire world.

Now, what we can do to help them are minimalism the amount of underage workers like giving scholarships to children from poor family and giving economic aids to poor family. Government must be responsible and not closed their eyes to this affair because their acts will make international party give our country bad opinion. This problem will ashamed our country in the eyes of international
