Piloting a chemical-recycling process for polycarbonate plastics

Covestro AG (Leverkusen, Germany; www.covestro.com) has developed a chemolysis process for recycling polycarbonate back into monomers. In laboratory trials, the process has been shown to recycle waste streams with more than 50% polycarbonate content into monomers, closing the loop to…

Preventing Dust Explosions with Flow Analysis

Dust collection systems are often designed using simple rules of thumb that may not be sufficient for proper operation. Flow analysis can ensure that the systems meet requirements The presence of dust is one of the many potential causes for…
