Hanoi (VNA) – An agricultural wastetreatment that uses bioproducts has been developed by scientists from theCentre of New Material and the Hanoi Gardening Association. 

Two main inoculants,bactericidal polymer liquid Medipag – 20 and bio-activated powderBioaktive-Eco, have been compounded by the centre to create a novel method ofcontroling wastewater odor.

Vu Hoan, President of the HanoiUnion of Science and Technology Associations, said that this model couldreplace old waste treatment technologies that use hazardous chemicals. Besidestheir technological and environmental advantages, the two compounds areaffordable.

Bui Cong Khe, Director ofCNM, said that the method has been used in dairy farms, poultry farms, fishcages and public landfill.

Since 2014, it has beenwidely adopted in Gia Lam district’s Phu Dong commune and some farms in thedistricts of Quoc Oai and Soc Son.

The research group alsoconducted seven training courses for 420 trainees and transferred thetechnology to several other localities.

Dang The Quan, head of the Phu Dong commune People’s Council, praised the innovations as a useful tool forprotecting the farming environment.

According to him, the twocompounds are effective in sterilising lodgings and feeding equipment, cleaningsewers and reducing waste odour at the 40 dairy farms where they are used, outof the area’s 777.

At pilot spots in thedistricts of Quoc Oai, Soc Son and Chương My, the technology is highly rated byfarmers for its ease of use and visible effects. According to them, it improvesthe disease resistance of poultry and cattle, which helps to increase thequality of dairy and meat products.

The technology helpedaddress the pollution in the landfill of Chuong My district’s Quang Bi communeand was successfully applied in the Central London Reef in Vietnam’s Truong Sa(Spratly) Archipelago.

Bioaktive-Eco has been usedin livestock farms and Medipag-20 in hospitals and military trenches. Initialresults from the experiment showed that the smell of dampness in the militarytunnels and trenches was greatly reduced. Mosquitoes and odours in and arounddrainage channels were also considerably reduced. According to scientists, thetwo compounds are environmentally friendly and safe.

These compounds are alsoone of the highlighted products competing in the "Green Truong Sa"Programme in the period 2016 – 2018, launched by the Central Committeeof the Ho Chi Minh Communist Youth Union in cooperation withthe navy. If a pilot project in two islands of Truong Sa island district yieldconsistently positive results, the navy will widen the use of the products inother island localities.

Because of its potential,the technology was recognised by the Vietnam Fund for Supporting TechnologicalCreations (VIFOTECH) in 2016. -VNA
