ACC: Plastic Bottle Recycling Declines Slightly

Plastic bottle recycling declined slightly in 2017, slipping 3.6% to 2.8 billion pounds, according to figures released by the Association of Plastic Recyclers (APR) and the American Chemistry Council (ACC). The 28th annual National Postconsumer Plastic Bottle Recycling Report indicates the overall recycling rate for plastic bottles for the year was 29.3%, down 0.4 percentage points from 29.7% in 2016. The five-year compounded annual growth rate for plastic bottle recycling was 0.1%.

Factors that contributed to the industry challenges included changing export markets and a 3.6% drop in material collected for recycling. Ongoing increases in single-stream collection also led to increased contamination of recyclables in the near term. In addition, growth in the use of plastic in bottles was offset by continuing progress in lightweighting and increased use of concentrates with smaller, lighter bottles.

In 2017, polyethylene terephthalate (PET, #1) bottles collected for recycling decreased by 27 million pounds. The collection of high density polyethylene (HDPE, #2) bottles, which includes bottles for milk, household cleaners and detergents, fell by 70.3 million pounds (6.3%) to just over 1.0 billion pounds for the year. The recycling rate for HDPE bottles slipped from 33.4% to 31.1%.

Exports of HDPE bottles fell nearly 28% from 193 million pounds to 140 million pounds, or 13.4% of total HDPE bottles collected in 2017. The processing of recycled HDPE sourced domestically and imported fell by 31 million pounds in 2017.

“Plastic bottle recycling is proving to be resilient in the face of short-term challenges,” says Steve Alexander, president of APR. “The recycling industry is responding in kind, with some investing in increased U.S. infrastructure, a clear sign of a positive long-term outlook. These investments underscore the need for continued consumer participation and convenient access to recycling programs.”

“Increasing plastics recycling is a critical part of moving toward a more circular economy, and commitments made across the value chain—from brand owners to plastics makers to recyclers—give us good reason to be optimistic about the long-term prospects for plastics recycling,” says Steve Russell, ACC’s vice president of plastics. “Plastics makers in North America and Europe have committed to recycle or recover all plastic packaging by 2040.”

This year’s survey found the collection of polypropylene (PP, #5) bottles fell 15.2% to 31.1 million pounds, as the PP collection rate dropped to 17.2%. PP caps, closures and non-bottle containers are widely collected for recycling in the United States, and these data are presented in a separate report on recycling non-bottle rigid plastics, which will be released in the coming months (until then see the 2016 Rigids Recycling Report).

Together, PET and HDPE bottles make up 97.0% of the U.S. market for plastic bottles with PP comprising 1.9%, LDPE 0.7% and PVC 0.3%. Together, PET and HDPE comprise 98.8% of bottles recycled with PP comprising 1.1%.

Data on PET recycling referenced in the report were separately funded and published by APR and the National Association for PET Container Resources. A separate report, entitled Report on PET Container Recycling Activity in 2017, is available on APR’s website.

The 2017 United States National Postconsumer Plastic Bottle Recycling Report is based on a survey of reclaimers conducted by More Recycling, formerly Moore Recycling.
