Wastes Helping the Future

By Beatris Bogomilova

China is a highly populated country where people are not very wealthy and many live in substandard housing. Rural areas in China are very common and unfortunately a large part of China’s population consists of farmers. In order to assist farmers with a more financially pleasing lifestyle and to prevent some of the world’s greenhouse gases, the ancient ways of biogas digesters are brought back. Biogas is a combustible composition of gases created by organic wastes that can ferment in the absence of oxygen. The use of simple biogas digesters began in 1920 and slowly progressed to the 1980s and solved minor problems such as manure disposal and hygiene improvement. In China, biogas is now used as anaerobic digestion (also called biogas digestion) that manages wastes and results in beneficial results.

Farmers create human and animal wastes on a daily basis and those wastes often end up in water bodies, which then pollutes the water for used for agriculture and human necessities such as drinking or hygiene use. In order to prevent the waste disposal discarded into the rivers and lakes and keep the reusable substances from the waste, biogas digesters are created. Biogas digesters take the different wastes and break them down into components that can be used for types of energy and agriculture. Biogas digesters provide methane that can be used for fuel for cars, cooking and heating water, as well as providing a great organic fertilizer with major nutrients such as nitrogen or phosphorus for crops to grow faster. “Using the biogas digesters to deal with the pig and poultry wastes, biogas energy becomes available for processing tea and heating the chicken coop, and there’s a fodder for fish and pigs and fertilizers for tea trees and the paddy fields, and no pollution is exported to surrounding areas.” This reuse of wastes really makes wet waste a great thing for future of our world since it will save the world’s most useful natural resource - water.

The biogas digester helps the living conditions of farmers in many ways. Farmers do not have a lot of fresh vegetables in the winter and the pigs in the farms do not fatten in the winter either. The digester gives energy through biogas, slurry and residue as fertilizers while the pigs enrich the greenhouse by producing quality to the vegetation through carbon dioxide. This then results in a longer spam for storage of fruit and grin and destroys unwanted insects, mould and bacteria that cause diseases.

Since biogas technology is very efficient, the Chinese have tried to make it more popular by holding classes that result in professionals who would introduce and encourage the technology to the rest of the world. In 2005, six thousand farmers were trained in Shanx Province and four thousand of them got National Biogas Professional Technician Certificates that then provides international training.

In conclusion, biogas digesters help farmers with disposing the waste from human sewage and animal wastes in a way that will not pollute the waters or affect the agriculture. Waste can be seen as a positive aspect to the world if reused for its beneficial substances and biogas digesters are invented just for that reason. Farmers profit from selling fuel and valuable crops thanks to the fertlizer produced and they also take part in saving the future of the earth’s waters, agriculture and wastes. Today, a lot of the Chinese population is moving from rural areas to the urbanizing cities, which helps to decrease the slums in China due to the high population rate and wastes. ...On the way to a better world!
