Kangwon Province built a production base of additives with a large capacity to provide them to industrial establishments and families.

With the additives, local industrial factories in the province fill up the shortage of fuel, lowering the production cost.

Most of counties in the province began operating coal briquette plants with help of additives. Co-op farms make slaked lime and organic fertilizer with the additives-mixed ultra-anthracite and low-grade coal as fuel.

A brisk drive for introduction of activated additives is going on in other parts of the country, too.

The activated additives were developed by a woman scientist at the Munphyong Smeltery. She was awarded an engineering doctorate for the invention.
