The present invention relates to a method and apparatus for producing plastic products. The invention is particularly useful for recycling waste plastic materials and is therefore described below with respect to this application.
The increase in usage of plastic materials in everyday life has created a serious disposal problem since most types of plastic materials are not readily degradable. Efforts are therefore continually being made to develop methods for recycling waste plastic materials not only to alleviate the waste-disposal and pollution problems, but also to lower the need for virgin plastic and other raw materials (e.g., wood) in producing various products and thereby to lower the cost of such products.
