Recycling Nylon with New Catalyst from Northwestern University

Northwestern University chemists have developed a new catalyst that quickly, cleanly and completely breaks down Nylon-6 in a matter of minutes — without generating harmful byproducts. Even better: The process does not require toxic solvents, expensive materials or extreme conditions, making it practical for everyday applications.

Not only could this new catalyst play an important role in environmental remediation, it also could perform the first step in upcycling Nylon-6 wastes into higher-value products.

The research was published in the journal Chem.

Marks is the Charles E. and Emma H. Morrison Professor of Chemistry and Vladimir N. Ipatieff Professor of Catalytic Chemistry at Northwestern’s Weinberg College of Arts and Sciences and a professor of materials science and engineering at Northwestern’s McCormick School of Engineering.Recycling Nylon

He also is a faculty affiliate at the Paula M. Trienens Institute for Sustainability and Energy. Northwestern co-authors include Linda J. Broadbelt, the Sarah Rebecca Roland Professor of Chemical and Biological Engineering and senior associate dean of McCormick, and Yosi Kratish, a research assistant professor in Marks’ group.

Recovering building blocks for upcycling
To bypass these issues, the researchers looked to a novel catalyst already developed in Marks’ laboratory. The catalyst harnesses yttrium (an inexpensive Earth-abundant metal) and lanthanide ions. When the team heated Nylon-6 samples to melting temperatures and applied the catalyst without a solvent, the plastic fell apart — reverting to its original building blocks without leaving byproducts behind.

Polyester is not stain resistant

Recently, we attended a webinar about how to keep your home free of toxins.  In the conversation about which fabrics to choose for your furniture, one of the panelists suggested using a synthetic (polyester) fabric to avoid stains.

People often think synthetic fiber fabrics are naturally stain resistant. They are not. They are stain resistant because of the addition of chemicals which you do NOT want to bring into your home.   Recycling Nylon

Now, the situation is a little more complicated than: They are NOT.  Synthetic fibers are both hydrophobic, meaning that they resist absorbing liquids; and oilophilic, meaning that they more readily absorb oils and grease. There is a continuum of these states, hydrophilic – hydrophobic and oilophilic – oilophobic; but it is true that natural fiber fabrics are both hydrophilic and oilophobic.  This means that natural fiber fabrics absorb water well, but oil poorly.   Synthetic fiber fabrics are the opposite:  They are hydrophobic and oilophilic, meaning that they resist absorbing water but more readily absorb oils and grease.

The fact that natural fibers are hydrophilic also means that they clean much better than hydrophilic synthetics.  Washing machines (all washing action, with a machine, or by hand) depends on water absorption to clean.  The more absorbent the fibers, the better they will clean.   Recycling Nylon

So what do these hydro/oil phobic/philic characteristics mean for the staining and stain removal behavior of natural fibers versus synthetic fibers? It means that, lacking the addition of chemicals that we would all prefer to avoid, or that we should avoid AT ALL COSTS, a natural fiber fabric will absorb water-based stains more easily than a synthetic, but you will have an easier time removing that stain.  Natural fibers will resist oil-based stains better than synthetics. And should you get an oil-based stain, you will have an easier time removing it than from a synthetic fabric.  Synthetics will not clean in your washer nearly as well.   Recycling Nylon

Vietnam’s textiles and garments yet to fully unlock FTA’s advantages and potential

Vietnam textile and garment industry has not been able to fully capitalise on the advantages and potential of FTAs, according to the Ministry of Industry and Trade (MoIT).

To address this issue, the MoIT, as the leading agency for FTA negotiation and enforcement, has been enhancing connections with ministries, localities, associations, and stakeholders to establish a collaborative ecosystem to help the textile industry effectively leverage FTAs.    Recycling Nylon

According to Ngo Chung Khanh, deputy head of the multilateral trade policy department under the MoIT, the Vietnamese government has signed various FTAs with many markets around the world, with a key focus on reducing tariffs to the lowest and quickest levels and simpler rules of origin for Vietnamese goods, especially in the textile and garment sector.

In a recent survey by the Vietnam Chamber of Commerce and Industry (VCCI), while most enterprises had some understanding of the FTAs, only about 8 per cent possessed a clear understanding.    Recycling Nylon

According to the ministry, Vietnam’s trade balance has been significantly in deficit in the East Asian markets, amounting to nearly US$129 billion in 2022, with $60.5 billion in trade with China, $37.9 billion with South Korea, and $13.42 billion with Asean.

AI shows how microplastics are harming global soil and agriculture

In recent years, the accumulation of plastic waste in the environment has emerged as a pressing concern.

While the pollution of oceans by plastics is widely recognized, the presence of microplastics in soils across the globe is equally alarming.    Recycling Nylon

These plastics, breaking down into microplastics (MPs), significantly impact soil properties and, alarmingly, find their way into the human food chain, raising health concerns.

Microplastics, soil, and corporate sustainability

The effects of microplastics on soil are crucial in the realm of corporate sustainability, particularly under the ‘Environmental’ pillar of Environmental, Social, and Governance (ESG) goals.

Companies worldwide are increasingly expected to adopt eco-friendly approaches, with a strong focus on addressing plastic pollution.    Recycling Nylon

However, the complex interaction between soil and microplastics, influenced by the diversity of both soil types and microplastics, complicates understanding and managing their environmental impact.

Innovative research using AI machine learning

To bridge the research gap in this area, a team led by Prof. Yong Sik Ok, a Korean University Professor and a prominent figure in environmental governance, applied AI machine learning (ML) techniques to study microplastics in soil.    Recycling Nylon
