NRT is currently producing about 75 mask comfort products a day, with the first 300 to be delivered to Nashville hospitals May 6. | Courtesy of National Recovery Technologies (NRT).
Normally, NRT’s 3D printer is busy producing parts for optical sorters and other recycling machinery. But amid the pandemic, the company is also using the technology to make mask straps that help out health care workers.
If EVOH is used at too high of a level in an HDPE container, it can damage the quality of the recycled HDPE. | Koray Akar/Shutterstock
An innovation is allowing natural HDPE bottles containing higher levels of EVOH to be recycled into pellets that are free of yellowing, gels and specks.

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.

A Kellogg’s brand has begun using a pouch with an additive that compatibalizes its EVOH barrier layer and PE film during recycling.

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.
