<\/figure><\/div>\n\n\n\nAn eco-friendly process for spinning fibres from dissolved pulp emerged from a project at the German Institutes of Textile and Fibers Research (DITF). The process uses cellulose \u2013 from trees \u2013 and chitin from crustaceans \u2013 to yield blend fibres and cellulosic super-micro fibres. Designated HighPerCell, the project was extended to add renewable carbon fibres to replace crude oil-based carbon fibres.<\/p>\n\n\n\n
Biomass to high value materials<\/h3>\n\n\n\n
In collaboration with Japan\u2019s trading company Itochi, Finnish firm Mets\u00e4Spring developed a new process for producing textile fibre from paper grade pulp. It relies on a supply of never-dried paper-grade pulp and an ionic liquid solvent system. The partnership claims to yield higher output than possible with pulp dissolving processes. Itochi and Metsa Spring also rely on a green solvent\/solvent recovery process. In 2021, the company reached a capacity of 1 tpd at its demonstration plant.<\/p>\n\n\n\n
Netherlands-based Cellicon developed a method for extracting sugar from cellulose (bagasse) using ZnCl2 as the solvent \u2013 which it says provides a low-cost route.<\/p>\n\n\n\n
The process uses hemp, recycled cotton and cotton-polyester blends from textile waste as feedstock. The cotton can be re-worked to form nanocellulose, producing a high tenacity fibre which is suitable for sanitary applications.<\/p>\n\n\n\n
From synthetics to sustainable nonwovens<\/h3>\n\n\n\n
BFT is an example of a company developing cellulosic fibres from alternative feedstocks. BFT is promoting the use of hemp and flax as feedstock to cellulosic fibres. Both are agricultural products which grow quickly and can be by-products from crop production.<\/p>\n\n\n\n
In the past, these products have been difficult to use but BFT has already carried out commercial pilot trials with technology providers to make nonwovens. The company aims to be part of a transition away from synthetics. so that sustainable nonwovens including cleaning wipes and personal care products can be successfully made. Avoiding marine litter and supporting overall improved environmental responsibility is the goal.<\/p>\n\n\n\n
BFT estimates the value of the global nonwovens market at $50 million with 80% of volume currently satisfied by synthetic fibres but new legislation on plastics as well as carbon emission targets and brand owners\/consumer preferences for plastic-free products are all drivers for plastic-free alternatives.<\/p>\n\n\n\n
Swedish firm Renewcell dissolves used cotton and other cellulose fibres like viscose from end-of-life garments and textile production waste streams into a slurry. The slurry is dried to sheets of materials branded Circulose. Renewcell packages it into bales for supply back into the textile production value chain as a replacement for virgin materials like cotton, oil and wood.<\/p>\n\n\n\n
Renewcell’s market is growing. Iconic denim maker Levi’s announced plans to use Circulose in its classic 501 range, having already used Renewcell’s technology for some time. A mill with a 60 ktpa of pulp from recycled clothing is expected to come online in early 2022.<\/p>\n\n\n\n
Waste not, want not<\/h3>\n\n\n\n
China’s Sateri claims to be the world\u2019s largest viscose fibre producer with more than 1.5 million tpa of production. A vertically integrated firm, its portfolio includes viscose and Lyocell fibres, and the Finex brand with up to 20% recycled content.<\/p>\n\n\n\n
The potential for agricultural waste feedstock is a focus as Sateri strives for a 100% recycled fibre footprint by 2030. The company warns of a gap to be bridged as many circularity initiatives have not reached suitable scale. Sateri has a $200 million initiative for both alternative cellulosic fibre feedstocks and manufacturing. The company\u2019s partnerships legacy includes Renewcell, international forestry group S\u00f6dra and Finnish renewables firm Infinited Fiber Company.<\/p>\n\n\n\n
Learning the new 3Rs \u2013 reduce, reuse and recycle<\/h3>\n\n\n\n
In terms of bottlenecks, industry players believe customer awareness challenges remain. Improved education around the cleanliness and (lack of) toxicity for recycled product is essential to uptake, they believe. Despite the issues, manufacturers see a clear route to better environmental performance in cellulose-based textile.<\/p>\n\n\n\n
Research by environmental non-profit enterprise Canopy indicates an ample supply chain for driving a bio economic shift in fashion feedstocks.<\/p>\n\n\n\n
According to the organisation, China generates 26 million tpa of textile waste and India\u2019s straw residues amount to 92 million tpa. Canopy predicts that 200 ktpa of next-generation viscose fibre will come onstream within the next two years based on 4-5 producers known to be working on converting mills to use recycled feedstock.<\/p>\n\n\n\n
Indications that such initiatives are set to accelerate beyond 2023 is giving the industry a feeling of optimism around its ability to meet its consumers’ growing expectations for sustainabilty.<\/p>\n\n\n\n
Boosting sustainability in apparel<\/h3>\n\n\n\n
Earlier this year, a team of scientists at Massachusetts Institute of Technology discovered a way to turn polyethylene fibre and yarn into textiles using standard textile industry equipment. A thermoplastic polymer, polyethylene is generally found in packaging film, grocery bags and cable insulation. Compared to cotton and polyester, polyethylene fibre production is a lower energy intensive process. Polyethylene is also recyclable.<\/p>\n","protected":false},"excerpt":{"rendered":"
