摘要： Systems for drying resin granulates include a first and second drying chamber each defining an internal volume configured to hold the plastic resin; a source of heated air in fluid communication with the internal; a first vacuum source in fluid communication with the internal volumes of the first and second drying chambers on a selective basis and configured to, during operation, generate a first vacuum within the internal volumes of the first and second drying chambers; and a second vacuum source in fluid communication with the internal volumes of the first and second drying chambers on a selective basis and configured to, during operation, generate a second vacuum within the internal volumes of the first and second drying chambers to draw the resin pellets into the internal volumes.

摘要： Compositions and methods for making biodegradable plastic products are provided. The compositions include a destabilizing agent that makes the finished plastic biodegradable. The compositions also can include an oil-based carrier, such as cottonseed oil, that allows the biodegrading agent to be metered into a continuous plastic manufacturing process. The compositions further can include an additive that allows the biodegrading additive to combine with the carrier; an optical brightener to improve the appearance of the finished plastic product, and to indicate the presence of the composition in the finished product; and a pigment, so that the composition can act as a liquid coloring agent.
