Photo: B.Nguyen In Dong Nai, many production models applying biotechnology to recycle waste into input materials for other production processes, minimizing the amount of waste discharged into the environment are gradually being replicated. * Green production At the forefront of the movement to turn harmful wastes in agricultural production into raw materials for processing into other high-value economic products are enterprises with large investment capital. Viet Farm Trading Co., Ltd chose to invest in Xuan Truong commune, Xuan Loc district because this is a thriving locality in livestock. Starting a business, the business mainly manufactures livestock equipment and designs and constructs livestock barn systems. The barn system designed by the company is fully automatic from the feeding system to collecting chicken manure, cooling system… In which, the enterprise is very interested in waste treatment so that it can earn money. money instead of having to spend a lot of money to treat this waste source. Mr. Tran Quang Tinh, Director of Viet Farm Trading Co., Ltd shared: “The enterprise has invested in an organic fertilizer factory with a capacity of 200 tons/day and signed contracts for waste treatment for a number of corporations. large foreign-invested livestock groups in Dong Nai. In particular, livestock waste is used as a raw material for the production of organic fertilizers, bringing high economic value. Production of organic fertilizers from livestock waste of Viet Farm Trading Company Limited (Xuan Loc District) The story of sustainable agricultural production in a closed chain that takes advantage of all agricultural wastes and by-products, without creating environmental pollution is being replicated in farmers’ production. In the past time, H. Vinh Cuu is promoting a program to mobilize and support farmers to apply probiotics as pesticides, organic fertilizers from domestic waste and waste in agricultural production with the goal of achieving the goal. reduce production costs, increase added value for key agricultural products, local strengths. Here, agricultural waste becomes a resource, a natural organic substance that can help plants grow. Ms. Bui Thi Thuy, a farmer in Vinh An Town (Vinh Cuu District), said that after participating in a number of local training courses on organic farming, she applied biotechnology. Make your own organic fertilizers and use probiotics to create biological products that kill insects. She has improved the productive land more and more fertile thanks to this method. “The natural production method I am doing makes full use of all agricultural waste such as manure and organic waste to make fertilizer for plants, so the cost is very low. I am trying to perfect the chain of cultivation and processing according to a closed process, using fruit trees grown in my home garden as raw materials to make handmade products that are both unique and environmentally friendly,” said Ms. Thuy. * Zero-waste processing Trong Duc Cocoa Co., Ltd (Dinh Quan) has cooperated with a group of Assoc., PhD students of the International University of Ho Chi Minh City to carry out research projects on processing foods and drinks of economic value. benefits from cocoa fruit waste products. New product lines under investment include: production of cookies and non-fried instant noodles supplemented with cocoa pod powder; production process of vegetarian sausage and pectin from cocoa powder; the production process of nutritious drink from cocoa fruit flesh… The highlight of these products is the use of raw materials such as waste from the skin, cocoa fruit flesh to process valuable foods. nutritional and economic. The above cooperation program is part of the common goal of the enterprise, which is to focus on investing in deep processing, constantly diversifying products and foods processed from cocoa fruit, especially from cocoa fruit waste to create profits. competitive advantage for products not only in the domestic market but also in export. Mr. Dang Truong Khanh, Director of Trong Duc Cocoa Co., Ltd. shared that the enterprise would like scientists to accompany in researching new products from cocoa fruit. In particular, high-value foods are processed from materials that are waste products in the production process, contributing to adding added value to cocoa trees. The most unique product line to mention is the specialty of cocoa wine that is brewed from the flesh of the previous cocoa fruit, which is discarded during the production process. With the same opinion, Assoc. Prof. Dr. Pham Van Hung, representing a group of scientists from the International University of Ho Chi Minh City, said, diversifying many products from cocoa skin and flesh, which are waste products in the process. production process brings higher economic value. In particular, this is a product line that is beneficial to human health because it has higher antioxidants, meeting the demand for healthy food of today’s consumers. Research on these products is now almost completed and can be put into production immediately. However, the research team will continue to recalculate the production process and equipment. Hopefully, the cooperation of scientists and businesses will connect and bring more processed products to the market.

Raising pigs in a closed cold barn is a new direction in livestock development In 2019, according to professional statistics, Thap Muoi had nearly 10,000 pigs of 406 households destroyed due to African swine fever. Like other pig-raising households, Ms. Luong Thanh Huong’s farm of nearly 500 pigs in Hamlet 3, Tan Kieu Commune also destroyed 164 pigs, it is worth mentioning that in the same place, but the cages are raised in the traditional form. disease, and the cage in the form of a closed cold barn (just a few meters away) was completely unaffected. Ms. Huong said that last year, due to the African cholera epidemic, her traditional farm was also affected by the disease and had to be destroyed a lot, but in the form of a closed cold barn, she was not affected. rebuilt the barn, raising all in the form of cold barns. Raised in this form, pigs grow quickly, reduce a lot of costs and are consumed at a higher price than the market. The closed cold barn system is divided into 3 areas including: food processing area, pig raising area and biogas cellar complex to treat manure and wastewater. This is a modern farm with full equipment such as water cooling system, exhaust fan, automatic feeding and drinking trough, automatic temperature control system inside… Model of the barn. closed cold, the temperature is always stable, the pigs are less tired due to the influence of the hot sun, helping the pigs to exercise well, eat well and grow stably, less effort to take care and clean pigs should be consumed with price is higher than the market. Therefore, there are many breeding households coming to learn the model of livestock by a closed cold barn system. Also a large pig breeder, Ms. Nguyen Thi My Em from Hamlet 4, Tan Kieu Commune is intending to rebuild the barn in the form of a cold-closed barn, but is still facing financial difficulties. Raising pigs in a closed cold barn system is a new direction in livestock development today, but the initial investment is relatively large. Mr. Nguyen Hong Sang – Deputy Head of Technical Training and Technology Transfer Department, Thap Muoi Agricultural Service Center said: “Effectiveness when raising livestock in the form of closed cold cages is clear, but the common difficulties of farmers are obvious. raising livestock in the district is the source of capital, because raising according to this model requires relatively large capital. Dong Thap also has policies to support the development of household livestock production, but it is difficult for people to access this capital due to the habit of small-scale livestock production, which the policy is bound to be on a large enough scale, depending on the type of livestock. but have different regulations, must link consumption, environmental protection issues… so it is difficult for people to access”. In order to keep livestock from being affected by the epidemic, ensure environmental hygiene, safety and efficiency, in the coming time, Thap Muoi needs to strengthen the propaganda to change the practice of small and fragmented livestock to form of farm farming, concentrated, self-contained, sustainable livestock production.
