The Pyongyang Stevia Processing Factory established a process for recycling waste activated carbon based on a microwave generator.
Activated carbon is widely used in foodstuff and other industries as it has strong absorptive power to solutes in gas and solution.
The factory used activated carbon only once for refining juice and disposed of it as waste in the past, but now it reuses hundreds of kilograms of it a month.
The Pyongyang Tools Factory under the Pyongyang General Electric Cable Factory 326 has newly set up a technical process for producing waste alundum grindstone based on low-temperature bonding agent.
Waste alundum is a leftover from a process of separating raw materials for grindstone. For its low purity, it was not used in grindstone production.
However, the establishment of this process made it possible to effectively use the waste which had been kept idle as useless in the past.
The Sunan Disabled Soldiers’ Essential Goods Factory established a process for producing vinyl sheet from plastic waste and the Central District urban beautification station turns out various kinds of goods from waste.
The station makes blocks and plastic pipes in various sizes from waste. It also produces glass wool from scrap glass to make roofing slates, while extracting fuel oil from plastic waste.
