3M to halt production of some chemicals at Decatur plant

WHNT | September 19, 2019

The 3M plant in Decatur said Thursday it is halting some manufacturing processes. This announcement comes months after the company said it would stop the manufacturing of some perfluorinated chemicals amid a federal investigation. 3M said it told employees, state and federal regulators about the recent manufacturing change this week. However, it's not clear what manufacturing processes are being put on hold. "The people in Decatur and downstream in West Morgan and East Lawrence deserve better answers. There is not value to the word temporarily. Does that mean three hours or three years? They are not even telling us what the manufacturing processes are," says Tennessee Riverkeeper Founder David Whiteside. “3M takes seriously its environmental compliance obligations and continuously assesses its performance against those obligations and the Company’s commitment to environmental stewardship. While we continue to work with the EPA and ADEM on previously disclosed issues, we have elected to temporarily idle certain manufacturing processes. We will resume these processes as soon as practicable.”

A major shortcoming of traditional strategies is the fact that solving chemical engineering problems due to the highly nonlinear behavior of chemical processes is often impossible or very difficult. Today, artificial intelligence (AI) techniques are becoming useful due to simple implementation, easy designing, generality, robustness, and flexibility. The AI includes various branches, namely, artificial neural network, fuzzy logic, genetic algorithm, expert systems, and hybrid systems.

Technipaq Partners with DuPont Tyvek and Freepoint Eco-Systems to Reduce and Recycle Medical Packaging Plastic Waste

Technipaq& DuPont & Tyvek | September 20, 2021

Technipaq Inc., a leading manufacturer of flexible sterilizable packaging solutions and Tyvek Authorized Converter, proudly announces a new partnership with DuPont Tyvek and recycling partner Freepoint Eco-Systems, designed to significantly build upon the company's ongoing sustainability and recycling efforts. Commencing on World Cleanup Day (Sept. 18, 2021), Technipaq will be able to effectively divert its mixed material plastic waste stream, containing Tyvek® and other plastic waste, generated during healthcare packaging manufacturing at its Crystal Lake, IL facility, away from landfills and to Freepoint, where it will be recycled for use in the production of new 'virgin-quality' plastics and fuels. "DuPont Tyvek has consistently taken a leadership role in forging interdisciplinary partnerships within the global healthcare packaging and manufacturing value chain, which is an increasingly important topic for our industry as we collectively seek to achieve more sustainable solutions and create a circular economy," said Brian Rosenburg, President and CEO, Technipaq. "We are excited and honored to play such a major role in helping make this a reality." "This represents yet another great multi-stakeholder partnership designed to build a waste-free, 'closed loop' healthcare packaging manufacturing environment," said John Richard, Vice President, DuPont Safety. "The healthcare industry requires a broad spectrum of plastics to manufacture packaging solutions for medical device, diagnostic and pharmaceutical products. Recyclability of healthcare packaging manufacturing waste is an increasingly important topic for the industry as it seeks to achieve sustainable solutions and a circular economy. Bringing a market leader such as Technipaq into this initiative marks a significant, positive step forward for our industry overall," added Richard. "Freepoint intends to recycle waste plastic that is usually very challenging to recycle and is typically headed for landfill or incineration," said Kat Doerr, Vice President of Origination, Freepoint Eco-Systems. "By converting plastic waste into reusable products, less oil is required to be extracted from the ground. This results in a more sustainable economy and a healthier planet." Freepoint aspires to divert 170 million pounds of plastic waste from landfills at each of its facilities on an annual basis—the equivalent of reducing GHG emissions from up to 55,000 cars per facility. Tyvek is mainly made of High-Density Polyethylene (HDPE) and is certified 100% recyclable, making it compatible with existing and emerging (advanced) recycling techniques. Due to its unique combination of properties, Tyvek® allows for the facilitation of packaging solutions—such as mono-material structures—that meet the sustainable design guidelines established by industry leaders such as Healthcare Plastics Recycling Council (HPRC), CEFLEX and RecyClass.
