Readers of Plastics Technology magazine will have noticed a flurry of activity by injection machine builders in recent years to upgrade all-electric and hybrid presses to compete in the “Indy 500” of molding—high-speed, thin-wall packaging. Recent trade shows have showcased a slew of “packaging” and “speed” versions of high-tech presses.

At Molding 2019 in Indianapolis (March 19-21), you’ll have a chance to learn more about what makes the difference between standard models and the new breed of speed demons. In the afternoon breakout session on Medical, Packaging & Precision Molding on Tues., March 19, two speakers will address this topic:

Braskem has formed new partnerships for the development of chemical recycling, with a focus on transforming post-consumer plastics, such as grocery bags and packaging films for snacks and cookies, once again into chemical products.

The partnerships seek to further research into technologies that can transform plastics that are more difficult to be recycled mechanically into new chemical products. The research is being conducted in partnership with the Polymer Engineering Laboratory (EngePol) at the Alberto Luiz Coimbra Institute of Graduate Studies and Research in Engineering of the Federal University of Rio de Janeiro; the SENAI Institute for Innovation in Biosynthetics; and Cetrel. The latter is an environmental service company that started its activities in 1978 jointly with manufacturers located in the Camaçari Petrochemical Complex in Brazil—the largest integrated petrochemicals complex in Latin America..

IBM researchers have created a new technology called VolCat, a catalytic chemical process that can turn waste PET into a substance that can be fed directly back into plastic manufacturing machines in order to make new products. This announcement is part of IBM’s "5 in 5" predictions detailing five innovations that will reportedly help change our lives in the next five years.

Plastic bottles, containers and PET-based fabrics are collected, ground up and combined with a chemical catalyst in a pressure cooker set to above 200 C. With heat and a small amount of pressure, the catalyst can digest and clean the ground-up plastic, and the process separates contaminants (e.g., food residue, glue, dirt, dyes, and pigments) from material that is useable for new PET. The monomer takes the form of a white powder, which can be fed directly into a polyester reactor to make virgin-quality PET.

Five New Developments in Plastics Drying

While the buzz at last year’s NPE was all about Industry 4.0 and IIoT, there is also a lot going on to enable the drying process itself—as well as the plastics processes it serves—to become more efficient and produce higher quality output. Here are five of the top drying product developments in both categories from Novatec.
