Baled plastics for recycling.

A recent report from the nation’s largest waste and recycling hauler reviews the current state of reclamation capacity for PET, HDPE and PP in the U.S.

Houston-based Waste Management issued its September 2020 “Report on Recycling” to identify gaps in U.S. plastics recycling infrastructure, among other goals. The report, which is based on research and data-gathering from consulting firm Resource Recycling Systems (RRS), was brought about after advocacy group As You Sow called on Waste Management to disclose more information about its plastic management.

After As You Sow last year filed a shareholder proposal looking to compel the publicly traded waste giant to share information, Waste Management and the advocacy group undertook what both describe as “in-depth engagement.”

As You Sow issued a release this month expressing hope that the report “will serve as a valuable first step in a broader conversation with regulators, packaging producers and consumer brands about policies and practices required to rapidly increase the amount of plastic recycled in the U.S., especially those for which there are existing markets.”

Important regions lack PET processing

Of the big three resins, the analysis found that the PET reclamation sector has the most consistency. PET reclaimers “tend to be well established in the marketplace,” the report stated.

But the areas where PET generation is the highest do not always align with the existing PET processing footprint.

For instance, the Southeast and Southwest account for 55% of the country’s PET processing capacity, meaning material generated and collected in those regions have a nearby home. But few PET reclaimers exist in the heavily populated Northeast, the Mid-Atlantic and the Midwest, according to the report.

Overall, the U.S. generates about 7.3 billion pounds of PET containers and packaging per year, of which about 1.9 billion pounds are recovered for reclamation. The U.S. has the capacity to reclaim nearly 2.6 billion pounds.

There are some 27 PET reclaimers operating in the U.S., according to the report.

The largest end markets for recycled PET are fiber (47%), food and beverage bottles (21%), and sheet and film (19%), with smaller percentages going into strapping, non-food bottles and other products such as engineered resin.

HDPE reclaimers can take in more

Moving to the HDPE recycling sector, the Waste Management analysis found that though there are numerous reclaimers, they tend to come and go as supply and demand fluctuates.

The report found there are about 7.5 billion pounds of HDPE containers and packaging generated in the U.S. per year. Reclaimers process about 1.3 billion pounds of the resin per year, and have the capacity to handle about 1.8 billion pounds per year.

HDPE reclamation is also divergent by region, with some of the major generating regions having relatively low capacity. For example, the Southwest generates 16% of the country’s HDPE but only has 5% of the reclamation capacity for the resin.

Overall, there are 28 reclaimers processing HDPE in the U.S., the report stated.

Major end uses for HDPE include non-food bottles (37%), pipe (33%), lumber and decking (8%), with smaller amounts going into lawn and garden use, automotive, film and sheet, crates and buckets, pallets and more.

PP becoming increasingly attractive to sort

Finally, PP reclamation is still a relatively small sector, although it has increased in recent years alongside PP generation in the material stream.

“More reclaimers are processing PP, and the commodity value of this resin has made it attractive for MRFs to sort out of their inbound feedstock,” the report found.

Reclamation and capacity are strongest in the Southeast U.S., the report found, where there is a larger concentration of manufacturers that use PCR. The region “relies heavily on PCR for their manufacturing industry, contributing to their overall economy,” the report stated.

Overall, the U.S. generates about 3.7 billion pounds of PP containers and packaging per year, of which 420 million pounds are recovered for reclamation. Reclaimers have the capacity to handle about 504 million pounds of the material, according to the report.

There are 10 PP reclaimers that handle as much as 60% of the PP recycled in the U.S., according to the report.
