Warwick Research Creates Groundbreaking Reversible Adhesive Technology to Revolutionise Fashion Sustainability

Researchers at The University of Warwick, in collaboration with apparel automation pioneer CreateMe Technologies, have developed a revolutionary thermoreversible adhesive technology poised to transform the fashion industry.

This breakthrough, the result of three years of intensive research and backed by 19 patents, promises to make textile recycling significantly more scalable, reducing waste and improving sustainability in apparel manufacturing.

The research, led by Professor Remzi Becer and Dan Mackinnon Ph.D. from Warwick’s Department of Chemistry, in conjunction with CreateMe’s research scientist Yixin Liu, Ph.D., MS, has created an adhesive that allows garments to be bonded at low temperatures and later disassembled at high temperatures (above dry-cleaning levels).

This innovation directly addresses the fashion industry’s long-standing challenge of textile waste, where 92 million tons of fabric are discarded annually due to inefficient recycling processes.

The fashion industry generates approximately 92 million tons of textile waste annually, with a significant portion ending up in landfills. Today, textile recycling is inherently non-scalable due to the high manual labour resources required to de-stitch and separate non like-for-like fabrics and hardware for in-take.

This reversible adhesive technology enables fully automated bonded assembly and disassembly of garments for recycling. This disassembly process occurs at higher temperatures than typical washing and care operations, reducing the risk of inadvertent failure before the garment reaches the end of its life.

CreateMe and Warwick are actively engaging with industry leaders to scale this groundbreaking adhesive technology, extending its applications beyond fashion through beta testing and licensing opportunities. This scalable approach highlights the adhesive’s potential to address sustainability challenges on a global scale, transforming not only apparel manufacturing but also other industries and recycling industry partners reliant on efficient, circular production models.

Covestro Capacity for specialty films in Thailand expanded

With the mechanical completion of new production lines at the Map Ta Phut Industrial Park in Thailand, Covestro has further increased its global capacity for polycarbonate (PC) specialty films. The investment is in the higher double-digit million Euro range, the project has been completed on schedule. A total of around 40 new jobs will be created.

"The new production facilities are equipped with state-of-the technology to enable an efficient production and thereby reduce our CO2 emissions," says Thorsten Dreier, Chief Technology Officer of Covestro. “With the expanded capacity, we can meet our customers' growing demand for innovative specialty films, especially in medical technology, in the region Asia-Pacific and strengthen our Solutions & Specialties segment."

Covestro has been operating a production facility for Specialty Films in Thailand since 2007. The range comprises polycarbonate films from the Makrofol® range and Bayfol® products made from polycarbonate blends. These high-performance specialty films are used in many applications across multiple industries, such as healthcare, mobility and Identification Documents.

“The new production facilities are important to us because it enables faster time to market and at the same time expands our market access in Asia-Pacific.” says Aukje Doornbos, Global Head of the Specialty Films business entity. “With market-focused innovations and a stronger customer orientation we want to drive growth for Covestro.”

Since 2022, the Map Ta Phut site is ISCC PLUS certified, enabling it to manufacture and supply mass-balanced products. With the mass balance approach, bio-based or recycled raw materials are fed in at an early stage of raw material extraction and mathematically allocated to the finished products. This saves fossil raw materials and reduces CO2 emissions, while the quality of the mass-balanced products remains identical to that of purely fossil-based products. With this drop-in solution, manufacturers can continue to use their proven formulations, equipment, and processes.

ISCC is an internationally recognized sustainability certification for biomass and bioenergy. The standard covers all stages of the value chain and is used worldwide. Customers can use these products in their established processes and apply them to meet their sustainability goals. In addition, Covestro already offers a range of films made partly with plant-based raw materials or partly from recycled plastics.

Today's KNOWLEDGE Share : To understand brittle failure

Today's KNOWLEDGE Share

Time for some really basic "LEFM" (linear elastic fracture mechanics).

Fracture Mechanics essentially assumes all materials or parts do contain "defects".

It is a reasonable assumption if you think about dust and all sorts of contaminants (including fillers with poor surface treatments) present in our polymer plants, compounding facilities and molding shops.

If a defect is small enough, a tensile stress (steady or dynamic) will trigger a relatively stable and slow crack growth rate.

This is captured by the exponent "m", i.e. the slope of the linear region II of the graph shown above.

When the crack "a" reaches some critical length, the stress intensity factor K reaches the value K1c where the crack enters the unstable crack growth region, quickly leading to part failure.

Some polymers are good because the stable crack growth is really slow (low value of "m"), some polymers are good because they survive despite the presence of a large crack (high K1c value).

The overall performance of a polymer, for instance under a fatigue test, is a combination of these two fundamental characteristics.

It is time to brush-up your knowledge about polymer mechanical performance and failure mechanisms.

BASF’s Performance Materials division plants run entirely on renewable electricity in Europe as of 2025

BASF’s Performance Materials division completely switched all its European sites to renewable electricity. “As BASF, we want to enable our customers green transformation, and we believe it starts with us. This is our ambition and the goal of #OurPlasticsJourney,” said Martin Jung, President of BASF’s Performance Materials division. “The use of electricity from renewable sources such as wind or solar is necessary to achieve our climate targets.” The changeover applies to the compounding of Engineering Plastics, Polyurethanes and Thermoplastic Polyurethanes and Specialty Polymers. With the turn of the year, in total nine Performance Materials production sites across Europe have been converted.

Renewable electricity also plays an important role in the whole value chain such as in the choice of suppliers. For example, BASF Performance Materials sources glass fibers for the reinforcement of plastics from 3B Fibreglass, one of BASF’s suppliers that uses solar panels to generate electricity and has thus significantly reduced its carbon emissions. The reduced CO2 footprint of glass fibers is transferred to BASF’s products and ultimately to its customers. Such improvements will also apply within BASF’s value chain, to produce base polymers and other precursors for Engineering Plastics and Polyurethanes. “Ludwigshafen, as the world’s largest integrated chemical complex, cannot switch completely to renewable electricity from one day to the next. Our own combined cycle gas power plants produce electricity and process steam with a 95% efficiency at emissions far below the average grid level.

 

Within the next few years, BASF intends to continuously convert all its operations globally to renewable electricity. This will be achieved through the expansion of renewable energy production via significant projects. For example, the world’s biggest offshore windfarm owned by BASF and Vattenfall and located on the Hollandse Kust Zuid started its operations in 2023 and enables innovative, emission-free technologies at several production sites all over Europe. Schwarzheide, BASF’s second largest site in Germany, now integrates a 24-megawatt capacity from solar energy. “However, renewable electricity is not the only lever for reducing CO2 emissions. Green steam made from the electrification of processes and the use of alternative raw materials via the mass balance approach play an essential role in the transformation towards a sustainable chemical industry.

 

BASF aims to reduce its greenhouse gas emissions by 25 percent by 2030 compared to the base year 2018 and become climate-neutral by 2050. To achieve this ambitious goal, BASF is increasingly focusing on renewable energy, optimizing raw material procurement and production processes, and promoting and implementing a circular economy.
