FUEL FROM THE CORNCOBS : SOLUTION TO RESPOND POSITIVELY CONTRIBUTE

According to the General Statistics Office , the country currently has about 800,000 ha of corn . Processing of agricultural products were discharged approximately 1 million tons of corn cobs per year . The amount of new cob people use as fuel part , a very small fraction is used for growing mushrooms , remaining essentially discarded out of the road , causing stream pollution .

CongThuong - To make use of waste go to waste , and contribute to overcome the environmental pollution , Dang Van Cong , lecturer Warehouse

a Agro - Forestry , Northwestern University studied solutions produced using corn cob briquettes and fuel rods . The idea proposed by Mr. The idea is one of 16 World Bank in Vietnam Award for innovative science and technology in 2011. This is a new solution generate high heating fuel , replacing coal used in the drying of agricultural products , tile stoves and cooking needs of the people . This idea is also considered to contribute positively to cope with climate change , solve problems using sustainable energy , fight against pollution and climate change .

Dang Van Cong , nearly 1 million tons per year cob can create a cake of coal , large fuel rods , fuel used for cooking , drying agricultural products , burning brick ... There are 2 directions Manufacturer: First, cob after collection from the mill will bring crushed and mixed with some additives to coal agglomerated . Second, cob after being crushed in presses for forming the cob sticks ( similar to rice husk firewood ) .

Agglomerated molding process and will create a great force , making the density increases, the more mixed the additive will increase fire and completely burned , create toxic gases . According to Gong, the solution here is not only to create new fuel sources to replace high heating coal , but also solve the waste volume cob . In addition to a good fire , high heat , less smog , less harmful emissions , producing fuel from corn cobs also contribute to solving the problem of environmental pollution , the initial investment is not large , the source material is readily available and cheap , factory machinery and simple one-time investment and long-term use .

These products are sold to agricultural ovens , furnaces producing handicraft and people with cheaper third honeycomb coal prices than usual . The project is being implemented in Thuan Chau district , Son La province ... If production models and fuel briquettes from the cob is done on a large scale will contribute to limit the use of coal in technology brick burning , drying agricultural products. That not only meet the demand for fuel , but also contribute significantly to environmental pollution and combat climate change .
