North Korea: State-owned Komusan Cement has successfully deployed alternative raw materials derived from quarry overburden in cement production at its Komusan cement plant in Hamgyŏng Province. State-run Korean News has reported that the producer presented the resulting products at a provincial building materials exhibition.
The Komusan cement plant reportedly had ‘decades-worth’ of overburden in stockpiles, but previously lacked the equipment to properly process it.
