PYONGYANG, June 7 (Xinhua) -- Researchers in the Democratic People's Republic of Korea (DPRK) have developed a technology of making stone paper with plastic and limestone, the official news agency KCNA reported Monday.

The stone paper, much stronger than ordinary pulp paper and able to keep its color unchanged for a long time, can be remanufactured, the KCNA said.

It can be used in producing vellum, inflammables, one-off food containers, and billboards in particular because it is little affected by climate.

Researchers at Pyongyang Han Tok Su University of Light Industry are working on production of the stone paper.
