A regular procurement system was established throughout the country and various forms and methods have been applied in keeping with the reality.

In Pyongyang City, procurement exchange shops were arranged at 70-odd spots to collect different kinds of available materials for the factories.

The same is true of Kangwon, South Hamgyong and Jagang provinces.

Meanwhile, many industrial establishments have shared in the benefit from recycling.

The adoption of the DPRK Law on Recycling at the 3rd Session of the 14th Supreme People's Assembly provided a legal guarantee for ensuring the sustained development of the country's economy with its own effort, technology and resources.
