Utilizing waste from rice such as straw, rice husk ash ... helps farmers earn more income while contributing to the protection of living environment and production. However, in An Giang in particular, in the Mekong Delta and in the whole country in general, this activity has not fully brought into full play its inherent value.

In the period 2012 - 2014, the cooperation project "An Giang and Pitea - Sustainable Communities" will be implemented. The goal is to develop An Giang into a province that produces green rice and has sustainable agriculture, in parallel with raising people's incomes. Through it, help farmers better aware of the value of agricultural byproducts, especially from rice. Many demonstrations on straw collection, straw mushroom cultivation and straw incubation as feeds in livestock support have been implemented and have a high spillover effect. Not stop there, the regeneration of energy from rice husk (production of rice husk firewood, rice husk power plant), utilizing rice husk ash as fertilizer, used in construction ... has been formed, expanding more and more.

According to statistics, An Giang has more than 700 thousand tons of rice husks per year. Every 5kg of rice husk will generate 1KW of electricity, so with the amount of rice husk, the amount of electricity is very large. However, nowadays, husk is being used very waste for cooking fuel for cooking, burning bricks ... and the waste is polluting the environment. Therefore, the source of rice husk material obtained in rice production should be processed into electricity materials, in particular, rice husk into rice husk as raw materials for rice husk plants. According to Dr. Nguyen Trung Thanh (An Giang University), about 1,000kg of rice will mow 600kg of rice (60%), 140kg of bran (14%) and 260kg of rice husk (26%). Meanwhile, rice hulls can be used as fuel for incinerators; Production of handicrafts, biogas, materials in construction, production of water treatment materials, other applications such as biochar, thermoelectric ... Not to mention the amount of rice husk ash obtained from the rice husk. This is also a source of material for agricultural production, construction additives, silicagel production (desiccant) ... bring many benefits to people.

Director of the An Giang-Sweden Project Management Board Pham Ngoc Xuan said that the contents of the project have been implemented up to now. Many agricultural experts from the city of Pitea (Sweden) went to An Giang to organize many training courses on demonstration models utilizing waste from rice. Accordingly, to achieve the goal of not burning straw under the Strategy for management and efficient use of rice biomass to produce energy in climate change conditions for An Giang province until 2030; The groups proposed the addition of a straw manure in the field using a bio-product (Trichoderma).

Farmer support schemes within the framework of the project have been implemented, including the model of rolling straws, composting straw for cattle feed and growing mushrooms. The team members in charge of the demonstration models also trained people on technical methods of ure straw incubation; Methods of processing mushroom growing medium for high productivity; Outdoor and indoor mushroom cultivation. Besides, they also teach people how to preserve straw rolls. Since then, farmers involved in the project can apply and guide the surrounding farmers. The family of Pho Van Toi (Phu An I hamlet, Binh Hoa commune, Chau Thanh district) farmed about 50 breeding cows and 200 goats. Finding food sources for livestock is always a concern for family members, especially in rain. Later, thanks to the project supporting straw paper machines, plus training on straw incubation with ure has partly resolved the anxiety of the family. When the straw rolls back, just 4% urethane broth, in a week can be used for feeding cows. Want to shorten the time just add more molasses to the straw can be fed to the cow immediately. Previously, I and local breeding herders collect straw manually, cost a lot of money, "- said Mr. To share.

Thus, just as people change their minds, along with the entry of related industries, rice milling companies and companies in the province, it is entirely possible to turn things into "Leave" from rice to a significant source of revenue. Besides, it helps to protect the environment, reduce the greenhouse effect.
