摘要： A novel process has been found in which the two types of plastic particles having similar specific gravities in a mixture are safely, efficiently, effectively and economically separated after being soaked in a plasticizer for a predetermined amount of time. The recovered and reclaimed particles can be reprocessed without any additional steps other than washing and drying. This novel process is useful in recycling waste plastic materials especially those materials containing polyvinyl chloride.

摘要： A novel process has been found wherein multilayer plastic materials are efficiently and effectively separated. The multilayer plastic materials are divided into smaller particles, the particles are agglomerated and then like particles are separated from the other particles. This novel method is useful for recycling multilayer extruded plastic materials.
