Secondary recycling of plastics
Secondary recycling, better known as mechanical recycling (or material recycling), is the process of recovering plastics for the re-use in manufacturing plastic products via mechanical means [4–7]. Mechanical recycling of plastics can only be performed on single-polymer plastic.
Mechanical Recycling of Packaging Plastics: A Review
Secondary recycling requires sorting of polymer waste streams, reduction of polymer waste size, followed by extrusion. With proper control over processing conditions, many polymers can undergo several cycles of primary and secondary mechanical recycling without concern for loss of performance (Sections 7 and 11 ).

Design for recycling aims at avoiding, for example, additives that are detrimental for the polymer chains during the recycling process (Day et al., 1995), or at increasing the share of transparent or natural-color material, the secondary material of which has fewer aesthetic application restrictions. Both changes improve the secondary …
Waste: Circular Economy
Our Aspiration.

Recycling Basics and Benefits | US EPA
The study found that in a single year, recycling and reuse activities in the United States accounted for: 681,000 jobs, $37.8 billion in wages, and. $5.5 billion in tax revenues. This equates to 1.17 jobs per 1,000 tons of materials recycled and $65.23 in wages and $9.42 in tax revenue for every ton of materials recycled.
The secondary solution
The secondary material recovery facility (MRF) received, sorted and measured the recovery of recyclables from two types of material streams from four MRFs in Oregon and Washington. For more background on the pilot project, see the article "Taking an evolutionary leap" in the Fall 2019 issue of Plastics Recycling, available at
