Recycling solid wastes as polymer composites

Abstract

Recycling and / or reuse of by-products (waste) is a goal to be achieved under the current economic and ecological crisis. The reuse of waste leads to saving energy and raw materials reduces environmental pollution and risk factors for public health and so on. The solid organic or inorganic wastes have been immobilized in polymer resins used as a binder matrix. All obtained composites present very good physical-mechanical properties: high hardness, good strengths at abrasion and the compressive strengths are all above 90 MPa. They also have good thermal stability at high temperature variation and high stability in different aggressive media. Some of such polymeric composites have good sound absorption capacity depending on the proportion and nature of the waste used.
