While domestic collection of plastic bottles for recycling increased by 52 million pounds, or 1.8 percent, in 2018, the overall recycling rate declined slightly by 0.4 percentage points, according to figures released by the Association of Plastic Recyclers (APR) and the American Chemistry Council (ACC), both of which are based in Washington, in the “2018 National Postconsumer Plastic Bottle Recycling Report.”
In 2018, 2.9 billion pounds of plastic bottles were collected for recycling, according to the report. However, the overall recycling rate for plastic bottles was 28.9 percent compared with 29.3 percent in 2017 and 29.7 percent in 2016. The five-year compounded annual growth rate for plastic bottle recycling declined 0.4 percentage points.
According to the report, exports of postconsumer plastic bottles declined in 2018, with 90 percent of the total number of plastic bottles collected for recycling remaining in the U.S. for processing. Less than 8 percent of polyethylene terephthalate (PET) bottles and less than 14 percent of high-density polyethylene (HDPE) bottles collected domestically were processed outside of the country, with less than half of exports leaving North America, the report notes.
Domestic PET reclaimer capacity utilization rose to 80 percent, while HDPE capacity utilization was 73 percent. The capacity utilization rate for HDPE bottles was 67 percent in 2017 and 66 percent in 2016. In 2017, the PET capacity utilization rate was about 71 percent, having declined from 2016’s figure of 73 percent.
“Plastics recycling is a vibrant, resilient industry that continues to remain strong in a challenging environment,” says APR President Steve Alexander. “Despite the reduction in export markets, demand for quality recycled material remains robust, and many recyclers are investing in updating and expanding our domestic infrastructure to meet that demand.”
“Brand owners have made public commitments to use significantly more recycled content in their products and packages in the months ahead,” says Steve Russell, vice president of ACC’s Plastics Division. “And manufacturers across the value chain are creating more circular business models for using—and reusing—plastics. It is therefore increasingly important to get as much of the right plastics into the recycling bin as possible.”
According to the report, PET and HDPE bottles make up 97.1 percent of the U.S. market for plastic bottles, with polypropylene (PP) comprising 1.8 percent; low-density polyethylene (LDPE), 0.7 percent; and polyvinyl chloride (PVC), 0.3 percent. Together, PET and HDPE comprise 98.9 percent of bottles recycled, with PP comprising 1.1 percent.
The “2018 United States National Postconsumer Plastic Bottle Recycling Report” is based on a survey of reclaimers conducted by More Recycling, Sonoma, California.
