Additives retain starch in cardboard recycling
Starch is essential for imparting strength to corrugated cardboard boxes, but millions of tons of starch are lost in cardboard recycling processes annually because conditions are ripe for bacteria to thrive, and the microorganisms degrade starch by converting it to…
Cost-effective LGF-PP process
A new process for making long glass fiber polypropylene (LGF-PP) concentrates (glass-fiber-containing plastic pellets) allows a higher glass-fiber content than is possible with conventional processes. Plastics maker Trinseo (Berwyn, Pa.; www.trinseo.com) has developed the process, which is capable of making…
