BelSU has worked out how to process gypsum waste
Belgorod State University (BelSU) employees have developed technology and experimental industrial equipment for gypsum recycling.
“There are more than 7 billion tons of gypsum waste from industrial enterprises in the world today. In many cases, it contains radioactive elements and heavy metals, which makes their disposal difficult. The conducted studies have shown that our technology has a high environmental effect: as process waste is recycled, the amount of harmful impurities is more than halved,” commented Ivan Nikulin, Director of the Belarusian State University Engineering Center.
The most important research result is the possibility of obtaining mineral fertilizers for agriculture based on gypsum waste. Field tests conducted on an 80-hectare area proved that the new fertilizer increases the yield of major crops by 10-25%. The most susceptible to this fertilizer is soy; its yield has increased by 5 kg from 1 ha.
