We transform blended textiles wastes to new raw material with the same or higher value while mitigating the microplastic release

Recycling and Waste

Textile wastes recycling, polycotton recycling, blended fiber recycling, dyeing of textile, Textile treatment and functionalization, textile manufacturer

Today, less than 1% of textile wastes are recycled to produce new fibers for the textile industry. Furthermore, textile industry is responsible of 14MT of microplastic every year, important energy consumption, 20% of the clean water pollution as well as CO2 emissions. It is crucial today to produce new resource out of the textile wastes which are mostly burned or landfilled in order to preserve our natural resources, protect the environment and the human life.

Renasens develops a waterless technology to recycle pure & blended textile wastes & produce high value raw materials using supercritical fluids . The first step of the process is dyes & additives extraction from the polycotton wastes, and then cotton polymer dissolution (without depolymerisation) with a supercritical phase containing a co-solvent with a high affinity toward cotton. The recovered polyester fibers and defibrillated cellulose from cotton are both used as new fibers for the textile

Hardware

This technology involve the use of recyclable green solvents in order to extract the dyes and additives without destroying the fibers structure and property and then a meticulous separation of cotton and polyester fibers through the dissolution of the cellulose polymer while the polyester fibers remains intact. With this waterless technology, we do not depolymerise the cotton nor the polyester which preserve the fibers properties and energy.

Renasens AB is planning to build its pilot plant of 100 kg/day that will allow the first market validation. After that a pilot plant of 1 t/day will be built in order to supply our customers with polyester and Lyocell raw materials as well as services of dyeing and functionalisation of textile fibers. The goal is to licence Renasens technology to, among others, European & Asians countries where most of the textiles is produced today and this is why we are building a strong patent portfolio.

Our first application area is within textile recycling for fashion and clothing. We will be supplying our customers with recycled fibers as well as dyeing and treatment services. The second target is textile coming from hospitals and medical application and the goal will be to sterilise the textile using Renasens technology and then to recycle it. The third application is to use our technology in order to impregnate high value molecules into the textile and produce technical and medical textiles

We have performed an FTO prior to start writing our first patent application regarding the separation process of fibers using Renasens technology. This application prepared by Zacco AB will be pending before the end of the year 2023. Moreover, 2 other patent applications will be made early 2024 in order to protect in amore complete method Renasens technology.

ENVIRONMENTAL IMPACT

Renasens technology enables the generation of new resources within the planet boundaries, will reduce the use of new virgin fossil fuel based fibers, reduce the CO2 emissions related to the burning and or the landfilled textile wastes, reduce the water use and pollution related to textile production, as well as mitigate the microplastic release form the textile to the environment during its life cycle. The microplastics have a huge negative impact on the environment, ocean and human health.

By generating new resource out of textile waste, we reduce directly the CO2 emissions of production of new fibers (natural or synthetic), by recycling the textile, we avoid the CO2 emissions related to the landfilling and wastes burning, and also we reduce the CO2 emissions related to the textile production process since we do not depolymerise the recycled textile and we use a clean and energy efficient method.

Yes

Renasens technology allow the reduction by 5778 kgCO2eq comparing to primary source of fibers, avoid 423.4 kgCO2eq by recycling the textile wastes that would have been landfilled. Moreover, we do not use any drop of water which will limit the water use & pollution. The functionalisation treatment using our technology reduce up to 40% the microplastic release during the garment life cycle. The long-term goal is to reach at least 60% of potential microfiber release mitigation.

MARKET, CUSTOMERS AND COMPETITORS

We are targeting the textile recycling market in Europe as a first step and then in Asia. More specifically, our initial target is the polycotton recycling market which is estimated at 2B euros in 2022 and expected to reach 3,4 B euros by 2030. Our SOM estimated for the coming 5 years in Europe is estimated at 6,1 M euros.

Our first geographical market interest is in Sweden and France in the short term.

Our target customers are fashion brands and textile manufacturers willing to have a positive social and environmental impact though the sourcing of their raw materials and the process used to produce textile. Customers such as Ecoalf, Houdini and Patagonia.

We have validated the market traction with 107 potential customers among fashion brand and textile manufacturer who confirmed the market need and their interest on our technology, 5 out of those customers are willing to collaborate with as at early stage and 1 of them is going to be our early adopter where we are going to start a development project together early 2024.

Our main competitors targeting blended textile wastes are Once More, Worn again and Circ technology. They use water and break down the polyester structures to monomers, which among other reduce the quality of the regenerated fibers. Renasens´s technology allows the extraction of additives/dyes and the separation of fibers without their depolymerisation. Renasens technology is waterless, use green and recyclable solvent, produce high value raw materials and mitigate the microplastic.

Waterless and energy efficient technology using green and recyclable solvent in order to separate mixed fibers without depolymerisation or degradation of their properties. Our technology could be tuned for extraction or impregnation of textile which make it versatile with endless application. We re-engineer the textile wastes most polluting the world to create value and circularity.

TRACTION AND FINANCIALS

Renasens AB is part of the incubator LEAD at Norrköping and we are getting financial support from Vinnova (innovation checks) and Almi Företagspartner Östergötland AB. We are also bootstrapping.

Prototype and Validation

We have the first patent application, we have advanced the technology development where we proved at laboratory scale that we could remove dyes and additives from polycotton, we could separate the fibers without depolymerisation or damaging their properties, also develops a functionalisation method to limit the microplastc release. We are planning to recruit team members, start building a pilot plant, continue the technology development and raise funds.

Yes we are looking for pre-seed funding.

We are planing to raise 500 000 euros and we have a preference for strategy and industrial partners. This raised money will be used to increase the TRL of our technology from 4 to 5, start building a small pilot plants, pay for the two new patents and higher a textile engineer and a CFO.

TEAM

The CEO & founder is Jade Bouledjouidja, the core of Renasens´technology is partially coming from her PhD thesis. She is a chemical engineer & hold PhD in material science & green process. She had + 10 y.experience of new technology development, 2 y. of business development and +4 different family patents. She was the CTO of Woodoo SAS (Woodoo raised 34 M£). We have two senior advisors Serge Mouangue (ex Director Innovation Lab. Groupe Renault) and Johan Sundblad (CEO of united recycling).

Jade Abir Bouledjouidja has been working for more than 10 years now with new technology, recycling and alternative to fossil based material, she had been leading successful teams at Woodoo (raised 34 M£), Finecell and Trifilon. She has the support of two senior and successful advisors working with design, innovation and recycling. They support the company with strategic planning as well as connection with suppliers and customers. And we are looking to hire in order to build a strong team.

Our short long term hiring plan is to hire a textile engineer and a CFO early 2024 and to hire another textile engineer and a business developer (part time) late 2024. The goal is to build a strong team that will lead to the success, scalability and commercialisation of Renasens technology.
