State of the Art in Calcite and Polyolefins Recycling

Abstract

The article outlines several aspects regarding the efficient recycling of polyolefin wastes and crystalline calcium carbonate-based second raw materials (calcite) in order to obtain composite materials with improved properties. Several bottlenecks regarding the compatibility of the polymer with the inorganic filler are addressed, detailing the up-to-date available solutions, as well as several other issues, related to calcium carbonate particles aggregation and abrasivity diminishing in order to obtain composites with improved mechanical properties and stability. The need for new ecologic and chemically stable compatibilising agents defines the research in this domain as still an open and permanently improving issue.
