Plastics recycling issues for the computer industry: progress and challenges

Abstract

Plastics recycling has long been a weakness in achieving a high level of product recyclability by the computer industry. However, advancements in the use of plastic materials with recycle content in new products and the recycling of plastic scrap generated from end-of-life (EOL) machines have had a positive impact on product recyclability. Progress is being achieved through the individual and combined efforts of original equipment manufacturers (OEMs), plastic resin suppliers, recyclers, and industry associations. Limited processing capabilities have been developed in support of closed and open loop recycling alternatives to landfill or incineration. Industry associations such as the American Plastics Council (APC) are also addressing key recycling issues and impediments in a forum which includes OEM, resin supplier, recycler, and regulatory agency representation. The challenges addressed in the paper requiring new initiatives by those involved in computer plastics recycling include: (1) the development of suitable foodstreams to satisfy increasing demands for recycle materials, (2) more efficient recovery processes, (3) new end-use applications for mixed and contaminated plastics, and (4) improved economics to support the development of this recycling industry. Additionally, the potential impact of certain regulatory requirements on plastic recycling are discussed.
