The variability of recycled plastic streams doesn’t just present challenges in terms of extruding and molding products. It also complicates the feeding of plastic into compounding equipment.

PET thermoforms bring special baggage to the recycling process: Optical sorters often fail to differentiate them from bottles, and thermoform flakes are more prone to breaking into fines.
A pelletizing and melt delivery equipment company opened a lab in North Carolina, and a U.S. thermoforms company begins using sheets from resin made partly through a PET depolymerization process.

Kal-Polymers is spending up to $4 million to install an integrated processing line, which is boosting PP recycling capacity and allowing the firm to handle higher levels of contamination.

Erema Group got the go-ahead to use its technology to recycle HDPE into food and drink packaging and foodservice wares. Meanwhile, other companies got federal green lights for PET recycling.
Three major manufacturers announce they’ll use PET, PP and acetate produced via chemical recycling processes, and Procter & Gamble begins putting digital barcodes on bottles to aid in sorting.

When it comes to development and commercialization of chemical recycling technologies, interest is high. A chemical recycling workshop at last week’s Plastics Recycling Conference and Trade Show was sold out, with over 300 attendees.
Living Proof recently tested the recyclability of some of the company’s hair care product packaging.
The Association of Plastic Recyclers recently recognized the recyclability of three packaging innovations: a 100% plastic aerosol bottle, a tube with an EVOH barrier, and an HDPE bottle with copolymer coating.
