People turn pig manure into ... electricity

Using emissions in livestock to produce bright electricity is the initiative of Mr. Bui Minh The in Long Than hamlet, Long An commune, Chau Thanh district, Tien Giang province.

We went to his house when he was plying the generator completely. He said, this is his 200th generator.

Electromagnetic currents . waste

In order to successfully build a generator, Mr. The has researched and transformed the operation principle of an internal combustion engine by replacing fuel (gasoline, oil) with flammable emissions. When the engine is running, he converts the energy into electricity through the power generation system; using exhaust gas from animal husbandry contained in biogas digester, with air inlet system. According to him, it is important to build a carburetor for the engine to operate continuously and create a stable current.

In order to reduce investment costs, he took advantage of used 4-wheel motor vehicles to pull away - na generator. When fully assembled devices together, the engine is started with battery. Emissions in livestock are very sensitive, so the engine runs very "sweet ", thereby generating good electricity.

Generator of Mr. Bui Minh The.

Mr. World said: 'I have some knowledge about the mechanical field and love to build machines. In 2005, I happened to discover that imported cars have the ability to operate on gas. I think if using "mixed gas" of biogas digester in livestock can also explode the engine and easily make a useful power source. I brought this idea to the table and was supported by family members. I experimented at the family's mechanical facility in Dong Nai '.

At first, Mr. The experimented on a small engine. After many failures, he succeeded. When the engine worked, he thought of installing a diesel system to generate electricity.

In current large-scale animal husbandry, the power source is very important, if this cost is saved, the interest will increase. Mr. So reckons, a farm raising pigs over 50 can install a generator. His generator has a capacity of 4-5kW (equivalent to 70 neon bulbs). About 10 days of assembly, he completed a generator. The price of each machine is currently from VND 15-100 million (depending on capacity).

Dual benefits

According to the calculation of livestock households, a farm raising 500 pigs, one day and night consuming at least 50kWh of electricity, the price of business electricity from this time is 1,500-2,000 VND / kWh . If using biogas generators, then The cost of electricity is significantly reduced. With the VAC model, the power source can be lighted, and it can run the water pump . With farms that combine milling or food processing plants, this power source can also replace electricity. career .

Mr. Le Minh Quang - pig farm owner in Luong Hoa Lac commune, Cho Gao district (Tien Giang) confided: "My family always raises more than 100 pigs, since buying his generator, I save quite a large amount of electricity costs, reducing the environmental pollution ".

Mr. Nguyen Tien Linh - official of Tien Giang Agricultural and Fishery Extension Center said that the Center is recommending to farmers using his biogas generator. Recently, many cassava flour production facilities in the eastern provinces have come to order his biogas generator. Emissions from tapioca waste can run biogas to generate useful electricity .
