Bui Thi Phuoc's family (Cam Binh, Cam Xuyen) saved more than VND300,000 per month when using gas from biogas tanks.
After raising the total number of breeding herds from 3-5 children per litter to 20-25 litters, Mr. Nguyen Viet Thuy (Binh Phat Hamlet, Cam Binh) invested in a 10 m3 biogas tank with a total investment of over 13 Million dongs (of which 3 million dong is supported by the Asian Development Bank (ADB). According to Mr. Thuy, the use of biogas systems is very useful for agricultural production. Animal waste after incubation, microorganisms disintegrate into humus and gases, creates gas for domestic use, and the waste after biogas digestion is quite clean and there is Can be used to irrigate crops, fertilizer. "In addition to limiting the environmental pollution, the use of biogas tanks for cooking daily helped my family save a bit of fuel and gas," she said. In 2011, supported by the Dutch government's biogas project, Bui Thi Phuoc and other livestock producers in Binh Trinh village - Cam Binh district (Cam Xuyen) constructed biogas tanks using technology. Biogas waste disposal in livestock. According to Phuoc, instead of discharging waste into the garden as before, after the application of biogas technology, the entire waste of livestock herd was loaded into biogas reactors with a capacity of more than 7.5 m3. Through the process of immersion, treatment, the entire waste is recreated as a source of energy for cooking, lighting in the family.
Being the "fastest" growing area of livestock, in recent years, Cam Binh commune has always faced environmental pollution. According to statistics, there are more than 600 households involved in raising pigs in the household with a total of nearly 18,000 children. In addition to the economic benefits of livestock production, in recent years, farmers in Cam Binh often suffer heavy losses caused by disease. According to the Vice Chairman of the People's Committee of Nguyen Thien Toan, to limit the epidemic, to increase the resistance of animals, the localities have mobilized and encouraged local people to invest and build biogas tanks. Using biogas technology to solve the problem of environmental pollution in livestock. Throughout the implementation process, the use of biogas waste water treatment in livestock has not only brought economic benefits to the families, but also helped the local fulfillment of environmental criteria in the construction of new countryside.
According to statistics, our province now has more than 200,000 small and medium scale breeding households, accounting for 80.3% of the total livestock sector. Accounting for 75% of the total. Most of the small models are located in residential areas, waste treatment is not paid due attention, proper investment (using biogas tanks for waste disposal is too little, 5,000 biogas tanks / 200,000 households) feed); Some areas have high stocking density such as Cam Binh; Thach Hoi, Thach Thang (Thach Ha) ... make the environment polluted, affecting the life and activities of people. Dangerous diseases such as foot-and-mouth disease, blue ear in pigs, bird flu, etc. often occur, causing considerable economic losses for the people.
In the face of such situation, the use of biotechnology in animal husbandry is considered as the optimal solution to reduce environmental pollution, helping households to treat waste, protect public health and reduce house gas emissions. Glass, contributing to the development of sustainable livestock, biosecurity. According to experts, in order to maximize the efficiency of the use of biotechnology in waste treatment, localities need to apply multi-purpose technology in animal waste treatment, providing Electricity, gas, clean fertilizer; Full transfer of biogas technology, biowaste, micro-biological technology ... suitable for medium and small scale animal husbandry. At the same time, technical support and policy support will be provided to support farmers to build and renovate their housing and appropriate environmental treatment systems to reduce pollution.
