As we have been reporting in the last couple of months leading up to next month’s K 2019, a major theme across-the-board will be on sustainability and the ‘Circular Economy’. Biobased materials and additives will certainly be one focus and Total Corbion PLA (U.S. office in New York, N.Y.) which in late 2018  started up its  165 million lb/yr production plant in Rayong, Thailand, a 50/50 joint venture of Total and Corbion of The Netherlands, is one company that will showcase a broad range of its Luminy PLA products and applications.

Last year’s start-up marked a major milestone for both the joint venture and the bioplastics market. With this additional 165 million lb/yr facility, the global production of PLA bioplastics has been increased by nearly 50%, to 480 million lb/yr. PLA is a fast-growing polymer market with an estimated annual growth rate of 10% to 15%.

ExxonMobil has recently unveiled what it plans to demonstrate at the upcoming K 2019 trade show. As is the case with other materials and additives suppliers on which I report in a K 2019 preview article in our September issue, the company is addressing sustainability with the introduction of new solutions in a range of applications including packaging, automotive, consumer products, agriculture, building and construction, hygiene and personal care, and lubricants.

Said David Hergenrether, ExxonMobil Chemical vice president, Polyethylene, “ExxonMobil continues to innovate through our technology advancements, while working with customers to help them create sustainable solutions to meet value chain needs….At K, visitors can discuss their challenges and innovation ideas with us to discover the benefits of working together to develop sustainable solutions.”

As we approach the start of fourth quarter, it appears that prices of nearly all volume resins eroded in various degrees through most of the third quarter. Major drivers include supply outstripping demand, a slowdown in some key markets such as automotive and construction, lower GDP, slowed global demand, and tariff-related issues.

Here’s a look at how our industry colleagues with pricing expertise view things for each of the major commodity volume resins. They include purchasing consultants from Resin Technology, Inc. (RTi), Fort Worth, Texas, senior editors from Houston-based PetroChemWire; and CEO Michael Greenberg of the Plastics Exchange in Chicago.
