Silk Protein Production Process Established

The Pyongyang Kim Jong Suk Silk Mill established a process of producing silk protein by making use of waste water.

Its scientists and technicians, in close cooperation with a research team of Kim Il Sung University, scientifically proved the mixing ratio of a needed solution and other matters and succeeded in developing a method of industrial production.

They built a silk protein production workshop by rationally arranging the detailed processes of protein separation, dehydration, drying and grinding and other equipment.

The factory turns out hundreds of kilograms of silk protein from tens of cubic metres of waste water per day. Its annual output will amount to over 100 tons.

Silk protein, which contains large amounts of protein, carbohydrate, ash, microelements, etc., is widely used as feed, organic fertilizer and nutrient solution.
