-Plastics of the future will have many past lives, thanks to chemical recycling

Fully recyclable network polymers can be perpetually broken down and remade

One day in the not-too-distant future, the plastics in satellites, cars and electronics may all be living their second, 25th or 250th lives.

New research from the University of Colorado Boulder, published in Nature Chemistry, details how a class of durable plastics widely used in the aerospace and microelectronics industries can be chemically broken down into their most basic building blocks and then formed once again into the same material. The research was supported by the U.S. National Science Foundation.

It’s a major step in the development of repairable and fully recyclable network polymers, a particularly challenging material to recycle, as it is designed to hold its shape and integrity in extreme heat and other harsh conditions. The study documents how this type of plastic can be perpetually broken down and remade, without sacrificing its desired physical properties.

Conventional recycling methods mechanically break down polymers into powders, burn them or use bacterial enzymes to dissolve them. The goal is to end up with smaller pieces that can be used to make a new product — think shoes made from recycled rubber tires or clothing made from recycled plastic water bottles.

But what if recycling didn’t just offer a second life to plastics, but a repeat experience, being formed again into the same material?

That is what the researchers have accomplished. They reversed a chemical method and discovered they can both break and form chemical bonds in a high-performance polymer.

They do it by breaking the polymer — “poly” meaning “many” — back into singular monomers, a concept of reversible or dynamic chemistry. This method has created a new class of polymer material that, like Legos, can be easily built, broken apart and rebuilt. The method can be applied to existing, especially hard-to-recycle, polymers.

The results also suggest that revisiting the chemical structures of other plastic materials could lead to similar discoveries of how to fully break down and rebuild their chemical bonds, enabling the circular production of more plastic materials in everyday life.

“The ability to repeatedly recycle plastics without loss of performance is critical for the economy and environmental sustainability,” said Siddiq Qidwai, a program director in NSF’s Division of Civil, Mechanical and Manufacturing Innovation.

-Mussel Polymers announces new multifunctional carbon, aramid fiber coating

Specialty materials company produces poly(catechol-styrene) polymer that effectively bonds with many materials, providing enhanced adhesion and other surface functionalizing benefits.

In September 2022, Mussel Polymers Inc. (MPI, Bethlehem, Pa., U.S.) a specialty materials and coatings startup company from Purdue University (West Lafayette, Ind., U.S.), announced that it successfully coated carbon and aramid fibers with its bio-inspired poly(catechol-styrene) (PCS) catechol-containing polymer, which it says is a step forward in producing lighter, stronger fiber-reinforced composites.

According to MPI, PCS coatings improve bonding for a wide range of adhesive and composite chemistries while functionalizing material surfaces. This application of PCS is likely to significantly increase the strength and impact energy of fiber-reinforced materials and improve the use of coatings and adhesives with carbon fiber parts and materials.

While carbon and aramid fibers possess many positive attributes, they are notoriously difficult to bond with because they are smooth and chemically inert. Previous work coating carbon and aramid fibers with polydopamine (PDA), a catechol containing research agent-like PCS, showed that the shear strength of a single coated fiber pulled from its matrix increased more than 200% compared to that of a raw fiber. Further, the flexural strength and impact energy of reinforced composites made with the catechol-coated fibers increased more than 200%. Carbon-fibers – Polyamide-recycling

PCS is reported to be the first commercially available catechol compound used to coat carbon fibers, among its many other uses. MPI is developing products for applications in the dental, biomedical, defense, specialty coatings, industrial and marine industries.

“The MPI team successfully coated carbon and aramid fibers with PCS using a simple one-step, room temperature process,” Jason Stieg, chief commercial officer (CCO) of MPI, says. “These coated fibers were examined under the scanning electron microscope [SEM] at Lehigh University [Bethlehem, Pa., U.S.]. The resulting images were striking and showed complete coverage of the fibers. The ability of our polymer to bond to these surfaces has applicability in both advanced composite materials and the assembly and coating of carbon fiber parts.”

George Boyajian, CEO of MPI, says the company expects to expand its partnerships with new materials and products companies. Furthermore, the simplicity of the coating process may accelerate its adoption and enable safer and more environmentally sound materials.

-Recoup: Recycling Plastic Packaging in the UK

Recoup has published its 2022 UK Plastic Packaging Sorting & Reprocessing Infrastructure report, which found there is a clear bottleneck in the UK’s recycling infrastructure for plastic recycling.

The report highlights the UK’s ability to sort both household and non-consumer plastic packaging from other materials into separate plastic streams and to reprocess them into raw materials and products.

Recoup mapped the recycling facilities and researched the operational capacities in order to produce a number of scenarios to compare the requirements for recycled plastic packaging against the UK’s ability to produce the material. The scenarios looked at benchmarks set by both the UK Plastic Packaging Tax and if material export markets were no longer an option, something the UK relies heavily on to achieve its recycling targets.

This research found that significant increases are required for reprocessing plastic packaging in the UK. This includes the need to increase the current recycling infrastructure by five times for household-like plastic packaging and nine times for food-grade plastic packaging. Unless resolving this reprocessing bottleneck is given the necessary priority and investment, and ultimately, ownership, the UK will not be able to claim it has a world-leading recycling system.

Recoup believes it is imperative that adequate funding through the reform of the UK’s Packaging Producer Responsibility System (otherwise known as Extended Producer Responsibility) goes to the right areas.

The appeal comes from Catia Bastioli, CEO of Novamont: “A series of legislative inconsistencies in the EU are jeopardizing huge public and private investments”.
Bastioli Speaking at the presentation of the Symbola Foundation GreenItaly 2022 report, the CEO of Novamont, Catia Bastioli , asked the European Commission not to invalidate the development process of the bioeconomy sector, one of the most dynamic in the European economic framework. Carbon-fibers – Polyamide-recycling
“A series of legislative inconsistencies of the EU is jeopardizing the huge public and private investments made over the years in the bioeconomy sector, the value of which was reaffirmed only a few weeks ago in Brussels, at the EU Bioeconomy Conference 2022 – said the manager – . First of all, the ETS system which must be aligned with the green taxonomy with measures that guarantee the recognition of the value of biodegradable bioproducts of renewable origin, currently heavily penalized by the corresponding products of Asian origin, of fossil origin and with a significantly higher carbon footprint “.
A second point raised by Bastioli is the rapid implementation of the Carbon Borden Adjustment Mechanism (CBAM), decided by Europe so that low-carbon biomaterials should not be dumped resulting from the import of products that have a fossil carbon content from two to three times higher.
Still at European level – stated Bastioli – we need Ateco codes that recognize the value of innovative industrial plants for biobased and biodegradable products (which currently have to pay for CO2) and EER codes with which to exploit the by-products in a truly circular logic, with the awareness that this is a dynamically evolving sector that requires areas of experimentation.
“The bioeconomy must become a strategic element of European industrial policy and for this to happen it is necessary to go beyond the current regulatory framework, in the direction of a new Lead Market Initiative and market measures to support those bioproducts that can significantly contribute to the circular bioeconomy, as, for example, the United States and China are already doing – he concluded his speech.

High quality polyamides from plastic waste

With the new Ultramid Ccycled products, BASF helps you in the development of your sustainable product offerings

With its „ChemCyclingTM“ project, BASF is breaking new ground in the recycling of plastic waste. Chemical recycling primarily involves the use of plastic waste that has so far been recycled for energy or landfilled, such as consumer-related plastics that have been sorted out in the recycling process. In a thermochemical process, basic chemicals are obtained from these plastics. Which are then fed into the BASF Verbund as raw materials. Using a mass balance approach, these chemicals can be allocated to specific products manufactured in the Verbund, such as our Ultramid Ccycled products. Fossil raw materials are thus replaced and saved. Carbon-fibers – Polyamide-recycling
