Polystyrene (PS) foam can be brought to trailer-mounted drop-off sites by residents of High Point, North Carolina, as well as the nearby towns of Jamestown and Archdale. The Ingleside Compost Facility, the High Point MRF, and the High Point Public Library are among the locations. “Residents have already shown a positive response to recycling polystyrene foam,” says Rebecca Coplin, beautification supervisor for the city of High Point. "The two trailers used by Tiny House Community Development to collect foam are changed once a week, the MRF receives 10–20 drop-offs every week, and twice a year, there is an inflow of foam from the High Point Furniture Market.

At present, the district has purchased a foam recycling machine for recycling through subsidy support. The foam densifier currently used can process up to 300 pounds of PS foam, PP foam and PE foam per hour. A 56-foot truckload of PS can be compressed into 14 ingots, each weighing 56 pounds and measuring approximately 2 feet by 1 foot by 18 inches. In view of the complicated types of waste foam, GREENMAX recommends using recycling equipment such as foam densifier, which compresses the plastic foam by heating and melting it. Therefore, the compression effect is better, and more types of foam can be processed. The compression ratio can reach 90 :1. 

Foodservice Packaging Institute President Natha Dempsey states, "The Foam Recycling Coalition aims to support communities like High Point as they work to increase recycling for residents by adding more materials to the recycling program." "We commend High Point for moving to remove valuable materials that can be turned into new products from the landfill." This shows that it is not that various waste foam cannot be reused, but that the early recycling work is not perfect, resulting in a low reuse rate. Using foam densifier to compress foam into compact ingots can greatly increase the probability of participating in recycling. Because investment in foam densifier reduces subsequent recycling costs, more and more people will invest in foam recycling. , it is precisely because of the application of foam densifier that foam recycling has become a sustainable project. Compressed EPS, EPE, and EPP foam can be made into plastic particles of various colors and then put into new production.
