Plastic bottle recycling held nearly steady in 2015, with a slight decrease of 0.5 percent from 2014, according to figures released jointly today by the Association of Plastic Recyclers (APR) and the American Chemistry Council (ACC). The 26th annual National Post-Consumer Plastics Bottle Recycling Report 聽indicates the overall recycling rate for plastic bottles for the year was 31.1 percent, down slightly from 31.7 percent the previous year. Since 2010 plastic bottle recycling has grown by nearly 400 million pounds, increasing on average by nearly 80 million pounds per year, or 2.9 percent annually.
Following 25 consecutive years of growth, several factors contributed to the recent plateau, including a drop in material collected available for recycling, reduced exports and increased contamination of recyclables. In addition, use of plastic bottles in packaging applications continued to expand but was offset by lightweighting and increased use of concentrates with smaller, lighter bottles.
In 2015, polyethylene terephthalate (PET, #1) recycling decreased by 15 million pounds. The collection of high density polyethylene (HDPE, #2) bottles, which includes bottles for milk, household cleaners and detergents, dipped slightly (0.4 percent or 4.8 million pounds), but overall held steady at just over 1.1 billion pounds for the year. The recycling rate for HDPE bottles slipped (0.4 percent) to 34.4 percent.
Domestic processing of recycled HDPE continued to grow for the fifth consecutive year. Domestic reclaimers processed over 1 billion pounds in 2015, an increase of 4.4 percent. Total domestic capacity to process postconsumer HDPE grew to 1.46 billion pounds with reclaimers continuing to use assets to process non-bottle HDPE and PP.
Exports of HDPE fell 16 percent to 184 million pounds while imports rose by 25 percent to nearly 66 million pounds. Given steady domestic collection, these trends resulted in U.S. reclamation plants purchasing nearly 44 million pounds in additional material. Domestic reclaimers purchased over 1 billion pounds of postconsumer HDPE for the year. 鈥淭he plastics recycling industry has a history of growth that spans a quarter century and has weathered many factors,鈥� said Steve Alexander, executive director of APR. 鈥淎s a result of expanded infrastructure and demand, this industry remains well positioned for long-term growth.鈥�
鈥淎ll of us should remain diligent in recycling our plastics,鈥� said Steve Russell, ACC鈥檚 vice president of plastics. 鈥淧utting the right materials into the bin helps make processing more efficient, which supports the long-term growth and stability of plastics recycling.鈥�
This year鈥檚 survey also found the collection of polypropylene (PP, #5) bottles rose nearly 20 percent to reach 32 million pounds, as the PP collection rate climbed to nearly 18 percent. 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 鈥�2014 Rigids Recycling Report鈥�).
Together, PET and HDPE bottles make up 97 percent of the U.S. market for plastic bottles with PP comprising 1.8 percent, LDPE 0.8 percent and PVC 0.3 percent. The 2015 Report reflects minor corrections in methodology for PP and HDPE in 2104 and 2015. Details on the corrections are provided in the introduction. 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 2015, is available on APR鈥檚 website. The 2015 United States National Postconsumer Plastic Bottle Recycling Report is based on a survey of reclaimers conducted by Moore Recycling Associates, Inc.
