From the Sector

• Carbios has succeeded in producing a 100% enzymatically recycled white PET fiber from colored textile waste
• At the same time, the company has produced the first 100% recycled PET bottles, that have successfully passed the food contact validation tests, from the same textile waste.
• Carbios received €827,200 for the validation of this final technical stage of the project co-funded by ADEME

Carbios announced the validation of the 3^rd and final technical step of the CE-PET research project, co-funded by ADEME3 (France’s Environment and Energy Management Agency), for which Carbios is the lead partner alongside its academic partner TWB. This achievement confirms, once again, the full potential and breadth of Carbios’ enzymatic recycling process, C-ZYME™. This breakthrough innovation makes it possible to produce a wide variety of products of equivalent quality to those of petro-sourced origin from any PET waste, including textiles.
 
The first white PET fiber recycled enzymatically from colored textile waste
Worldwide, around 90 million tons of PET are produced each year, more than 2/3 of which are used to manufacture fibers. However, only 13% of textile waste is currently recycled, mainly for downcycling, i.e. for lower quality applications (such as padding, insulators or rags). By successfully manufacturing at pilot scale a white PET fiber that is 100% enzymatically recycled from colored textile waste, Carbios is paving the way for the circular economy in the textile industry.  C-ZYME™ is now on the doorstep of industrialization and will soon enable the biggest brands to move closer to their sustainability goals.
 
Emmanuel Ladent, Chief Executive Officer of Carbios: « Thanks to our breakthrough process, it will soon be possible to manufacture, on a large scale, t-shirts or bottles using polyester textile waste as raw material. This is a major breakthrough that gives value to waste that currently has little or no value. It is a concrete solution that opens up a global market of 60 million tons per year of potential raw materials and will help to reduce the use of fossil resources. »
 
Separate collection of textile waste soon to be mandatory in Europe
From 1 January 2025 the separate collection of textile waste, which is already in place in some countries, will be mandatory for all EU Member States (European Directive 2018/851 on waste).  Carbios’ process will enable this waste to be sustainably recovered and included in a true circular economy model.
 
These technological validations were carried out as part of the CE-PET research project, co-funded by ADEME3. In particular, the project aimed to develop Carbios’ enzymatic PET recycling process on textile waste. The C-ZYME™ technology is complementary to thermomechanical recycling and will make it possible to process plastic and textile waste deposits that are currently not or poorly recovered. For the validation of this stage of the project, Carbios received €827,200 (€206,800 in grants and €620,400 in repayable advances).

BB Engineering GmbH (Germany) delivers a melt filter for recycling PET flakes to polyester manufacturer Indorama Polyester Industries (Thailand). Indorama will be using the type NSF38 filter in its recently assembled recycling system in order to produce rPET granulate from flake PET bottle waste. The NSF38 filter enables continual filtering – in other words, the system switches from one filter to the other during the process without the need for conversion shut-downs. The filter allows the processing of consumer waste for example, in the form of shredded PET bottles into new, high-quality rPET granulate. This granulate is subsequently processed into manmade fibers in spinning systems.

The NSF38 is a switchable filter with a filter surface area of ap-prox. 16 m2 on each side, with throughputs of between 1,000 and 1,900 kg/h. The filter inserts each contain 19 pleated filter candles (60 x 1,000mm Ø). The filter medium comprises a sin-tered metal fiber nonwoven with a filtration fineness of 25 μm. This ensures that the melt remains free of contaminants and gel particles, which in turn enables the production of high-quality end products.

• Renewable Carbon Initiative (RCI) published a strategy paper on the defossilisation of the chemical and material industry with eleven policy recommendations

The Renewable Carbon Initiative, an interest group of more than 30 companies from the wide field of the chemical and material value chains, was founded in 2020 to collaboratively enable the chemical and material industries to tackle the challenges in meeting the climate goals set by the European Union and the sustainability expectations held by societies around the globe.

RCI addresses the core of the climate problem: 72% of anthropogenic climate change is caused directly by extracted fossil carbon from the ground. In order to rapidly mitigate climate change and achieve our global ambition for greenhouse gas emission reductions, the inflow of further fossil carbon from the ground into our system must be reduced as quickly as possible and in large scale.

In the energy and transport sector, this means a vigorous and fast expansion of renewable energies, hydrogen and electromobility, the so-called decarbonisation of these sectors. The EU has already started pushing an ambitious agenda in this space and will continue to do so, for instance with the recently released ‘Fit for 55’ package.

However, these policies have so far largely ignored other industries that extract and use fossil carbon. The chemical and material industries have a high demand for carbon and are essentially only possible with carbon-based feedstocks, as most of their products cannot do without carbon. Unlike energy, these sectors cannot be “decarbonised”, as molecules will always need carbon. The equivalent to decarbonisation via renewable energy in the energy sector is the transition to renewable carbon in the chemical and derived materials industries. Both strategies avoid bringing additional fossil carbon from the ground into the cycle and can be summarised under the term “defossilisation”.

To decouple chemistry from fossil carbon, the key question is which non-fossil carbon sources can be used in the future. Rapid developments in biosciences and chemistry have unlocked novel, renewable and increasingly affordable sources of carbon, which provide us with alternative solutions for a more sustainable chemicals and materials sector. These alternative sources are: biomass, utilisation of CO2 and recycling. They are combined under the term “renewable carbon”. When used as a guiding principle, renewable carbon provides a clear goal to work towards with sufficient room to manoeuvre for the whole sector. It enables the industry to think out of the box of established boundaries and stop the influx of additional fossil carbon from the ground.

The systematic change to renewable carbon will not only require significant efforts from industry, but must be supported by policy measures, technology developments and major investments. In order to implement a rapid and high-volume transition away from fossil carbon, and to demonstrate its impact, a supportive policy framework is essential. The emphasis should be put on sourcing carbon responsibly and in a manner that does not adversely impact the wider planetary boundaries nor undermines societal foundations. An overarching carbon management strategy is required that also takes specific regional and application-related features into account, to identify the most sustainable carbon source from the renewable carbon family. This will allow for a proper organisation of the complex transition from today’s fossil carbon from the ground to renewable energy and to renewable carbon across all industrial sectors.

RCI has developed eleven concrete policy recommendations on renewable carbon, carbon management, support for the transformation of the existing chemical infrastructure and the transformation of biofuel plants into chemical suppliers. The policy paper “Renewable Carbon as a Guiding Principle for Sustainable Carbon Cycles” is freely available for download in both a short version and a long version.

After the C.L.A.S.S. recent evolution of its communication tools, they are really pleased to introduce Circular Systems as new C.L.A.S.S. Material Hub partner.

Circular Systems is a California based materials science company, focused on creating a net positive impact on environment, society and economy through innovation. Its circular plus regenerative technologies provide systemic solutions for transforming waste into valuable fibre, yarns, and fabrics for the fashion industry.

Textile waste and agriculture residues are a huge problem, often burned, left to rot in the fields, or sent to landfills creating massive amounts of CO2. Circular Systems is looking at these waste streams as valuable resources, turning problem into a solution by converting them into high value materials for the fashion industry. The “Lightest Touch™“ philosophy, defines their mission to retain maximum amount of embedded energy in waste inputs while creating the “highest-value outputs” with the lowest impacts. Integration of these technologies into global supply chains is key without compromising quality, thus extending the life cycle of these materials.

Circular Systems has three waste-to-fibre platforms that offer an efficient management of textile and agricultural waste:

• The Agraloop™ refines natural fibers derived from agricultural crops into textile-grade fiber called Agraloop™ BioFibre™.  A NEW Natural Fiber mindfully sourced for circularity. With our specialized processing technique, cellulose fiber from stems and leaves are purified into soft fiber bundles ready to spin into yarns. The Agraloop™ processes leftovers from various food and medicine crops including, oilseed hemp/flax, CBD hemp, banana, and pineapple.
• Texloop™ Recycling produces high-quality GRS (Global Recycled Standard) certified recycled cotton fibre called RCOT™. Texloop™ preserves fiber quality for the next generation of recycled materials and blends with GOTS (Global Organic Textile Standard) certified organic cotton and Canopy approved man-made cellulosics to create near virgin quality yarns for knitting and weaving.
• Orbital™ hybrid yarns create high-quality materials with high-performance, using organic and recycled fiber inputs. Orbital's patent-pending technology produces inherent wicking and fast dry performance materials, even with 50%-70% natural fiber composition, eliminating the need for chemical finishes to create high-performance fabrics.

All Circular Systems yarns are GRS, OCS and/or GOTS certified and are in the process of developing  their own Crop Residue Standard with Textile Exchange that would relate to the Agraloop™ platform technology.
