The factory was established in 2003, belonging to Agricultural and Power Machinery Company. The Initial capacity was 50 tons of product/day with the materials consumption of 200 tons/day. The capacity is now increased to 60 tons of product/day and to 80 tons/day in near future.

Before applying cleaner production, the factory often faced the problem of wastewater pollution. The wastewater derived from filtering, settling processes contained BOD5 content of 2.5 times higher than Vietnamese Standard 5945-2005 (level B), and COD content of 2.11 times higher. At that time, AES Corporation (U.S) was constructing the wastewater treatment system to recover biogas applying the principle of CDM projects. However, the leaking of starch and water from residues was also cause to pollute the environment and material loss. To solve this problem, in 2008, the factory accessed the component of Cleaner Production in Industries of Ministry of Industry and Trade.

With the support from Nghe An Department of Industry and Trade, and Vietnam Cleaner Production Center, in 2008, the factory carried out the cleaner production assessment. In stage 1 (from September 2008 to May 2009), the factory established the cleaner production team led by Mr.Tran Van Long – Director of the factory - and other 6 members to carry out the cleaner production assessment on the whole of production line.  The assessment of the production processes, the verification of waste streams, the balance of materials and energy were worked out. Then all data collected were used for analyzing to find out the cleaner production options for each production processes.            

After the assessment and the determination of improving solution options, the factory conducted some house keeping options which required low cost and no cost with the total investment of 9.8  and brought in 310 /year. From June 2009, the factory conducted big investment options with part of expenditure sponsored by CPI. In stage 2 (from October 2008), the factory took the initiative in big investment solutions to thoroughly solve the environmental problems, viz. investing 6 billion (including 2 billion dong from CPI) in using peel and heads waste to produce bio-fertilizer supplying the tapioca farm and markets; constructing residues separating system combined with drying process to reduce the moisture content in the residues used for breeding food. These solutions helped the factory to save 3.1 billion dong per year as they reduced the material and fuel consumption, reusing solid waste, and reducing negative impacts to the environment.

The benefits brought in to the factory from cleaner production are detailed as follows:
