A thermal recycling unit for waste glass fibers has been launched by the producer of nonwovens and glass fibers Johns Manville Corp. (JM), Denver, CO/USA, in its Engineered Products plant in Trnava/Slovakia.
The primary goal of this investment is to achieve a tangible positive environmental impact by drastically reducing the landfilling of glass fiber waste.
This project is part of the company’s response to the European Commission’s zero waste program and the overall target for sustainable management of the planet’s natural resources.
The new Trnava unit has a projected recycling capacity of more than 3 tons/hour and consists of a warehousing area, feeding and transportation equipment, shredder, burning chamber and milling. After processing, the recycled glass powder is free of organic particles and reefed as raw material into the glass production process on-site, thus achieving a closed production loop. The project will keep more than 10,000 tons of waste out of the landfill each year.
JM has invested nearly €10 million into state-of-the-art technology and made sure the recycling capacity will allow further glass fiber production capacity growth in Trnava.
