Uneaten feed, organic waste and accumulated bottom sludge can steadily degrade water quality in aquaculture ponds, releasing toxic gases and raising the risk of disease. Vietnam Food Joint Stock Company (VNF) has developed Ecovital EM, a Bacillus spp. biological product that breaks down organic matter quickly, stabilises pond water and supports a more sustainable farming model. Used as a biological water treatment for aquaculture, Ecovital EM helps farmers keep water conditions steady while limiting waste build-up in the pond.

Fresh, raw and wet foods lose quality fast as microorganisms, mould and oxidation attack their colour, smell, texture and shelf life. From Vietnamese shrimp by-products, Vietnam Food Joint Stock Company (VNF) develops chitosan — a natural polysaccharide derived from chitin — as a preservation solution for raw, fresh and wet pet food. In VNF trials, chitosan sharply reduced microbial and mould counts and helped extend shelf life, giving pet-food makers a way to protect quality while reducing their reliance on synthetic additives.
