The tapioca starch industry has been aiming for sustainable development in its production process, to take responsibility for the environment, society, and economic development. Because the starch industry will cause bad impacts on the environment if they do not strictly manage solid waste and wastewater.

1. Why should efforts be made to go green in production?

Wheat starch is known as one of the main sources of raw materials serving a variety of fields and industries such as food, pharmaceuticals, textiles, etc. There is a huge demand for the consumption of this product. However, along with the current trend of a green economy, partners are also gradually paying more attention to input materials in setting standards for protecting human health and the living environment. Therefore, greening efforts in the production process not only meet new trends in the market but also bring prestige to the business’s operation.

In addition, greening is also one of the conditions to promote the sustainable development of starch enterprises, limiting the exploitation of natural resources, and reducing risks to the environment in the production process. It creates favorable conditions to bring domestic orders to international markets.

2. How have businesses greened the tapioca starch industry?

• Compliance with planting regulations

To produce quality flour, and meet the requirements of domestic and foreign markets. The growing tapioca starch process must be taken care of strictly. Therefore, currently, farmers, who have been cultivating and producing tapioca starch, are moving towards the green stage in cultivation such as: not using chemical fertilizers, stimulants, and food preservatives.

• BioGas tank wastewater recirculation

Because high organic matter content is in tapioca starch wastewater. Enterprises can recirculate wastewater in anaerobic tanks to produce biogas and serve other stages. With about 60% of methane CH4 obtained from the above process can be used as fuel for boilers in the drying process or run generators. It replaces fossil fuels such as coal and reduces pollutant emissions from coal burning. It helps businesses optimize production costs and develop sustainably.

In addition, we can also promote organic matter decomposition in anaerobic wastewater quickly by using microbial products BAC AD-1005. It strengthens and increases beneficial microflora, promotes biomass growth, and generates circulating energy.

• Composting from wheat residues

In the production of tapioca starch, the tapioca residue is a source of green by-products used to make compost. The main ingredients are organic matter and high fiber in the product, creating ideal conditions for fermentation to make microbial fertilizer. However, if applied directly, it will not bring high efficiency and also cause unpleasant odors.

Therefore, the quality of the finished manure is optimized, and controlled the pathogens present in the wheat residue compost. It is necessary to add additional sources of organic fertilizers such as BAC CS 1401 to boost the productivity and quality of agricultural products to bring economic efficiency while minimizing environmental pollution.
