Cultural roles of waste materials in landscape creation;

By analyzing the present state of waste and old materials management in molybdenum mines,new management approaches were proposed.

A kind of polypropylene pipeline with 600 mm inner diameter is manufactured in a plastic injection molding machine by hydraulic pressure from recyling waste intertexture which is modified by cross-linking agent and added some reinforced materials.

The current status of the separation techniques for commingled polyomer wastes was present in this paper after the characteristic and recycling methods of the polymer wastes were outlined.
