More Sustainable Production of New Green Monomers

Building on our 80-year legacy of innovation in sustainable adhesives, Collano proposes, together with Biosimo, a groundbreaking project to develop bio-derived monomers as replacements for petrochemical-based monomers. While bio-sourced monomers that contribute to stiffness are more readily available, e.g., isobornyl methacrylate from pine resin, “softer” monomers come from palm oil sources that could interfere with the food chain. Our ambitious goal is to create new bio-sourced monomers, which would be a remarkable achievement in the industry. Recently, Collano launched a pressure-sensitive adhesive for brand protection labels, based on renewable monomers. Due to the structure of the new monomer, this bio-adhesive outperformed petrochemical counterparts, offering a more secure product against counterfeiting. Unfortunately, these monomers are based on cocoa bean or palm oil kernel, competing with food and potentially with the new EU deforestation regulation. Other more exotic monomers are no longer available. E.g., itaconic acid and di-butyl itaconate, won by the fermentation of sugar with fungi. Unfortunately, the supply to Europe is very difficult, hindering new truly sustainable adhesive products. We want a green revolution in Switzerland, pulling raw materials manufacturing back to Switzerland.

All in One Solution: Revolutionizing Plastic Recycling

Modern life would be unthinkable without plastic, yet plastic waste’s environmental impact must be drastically reduced Increased mechanical recycling is key to conserving resources, reducing CO2 emissions, and strengthening Switzerland’s supply security for polymer materials.

To boost recycling rates and the use of recycled materials, innovative recycling technologies are needed. Particularly high-quality, closed-loop applications call for state-of-the-art installations and new technological equipment. However, Switzerland faces challenges due to the wide variety of polymers used and the relatively small quantities collected, making large-scale recycling plants difficult to implement.

The key challenge is achieving local plastic loops for diverse polymers without substantial investment in new facilities that struggle with low input volumes. This project aims to pave the way for an ‘all-in-one’ recycling solution that integrates multiple polymers within a single installation. By developing a multi-polymer recycling system, InnoPlastics AG aspires to set a new benchmark for circularity in plastics, fostering innovation and driving sustainability across the industry.

Membrane for thermal energy storage 

Thermal energy storages are one of the key technologies to solve the energy crisis, particularly the winter gap. One of the most popular solutions is the so-called pit-storage, a large man-made hole in the ground which is sealed off from the earth by a polymer liner. This liner should prevent the water from leaking into the environment. But state of the art liners exhibit high water vapor diffusion rates and therefore leak warm water into nature. To change this, we need new technologies for these liners, but there is no test standard in place to test water vapor diffusion rates at higher temperature. In this project we will develop such a test method and enable innovative new solution for liners for thermal energy storages.v 

More Sustainable Production of 2-Ethylhexanol

Building on our 80-year legacy of innovation in sustainable adhesives, Collano proposes, together with Biosimo, a groundbreaking project to develop bio-derived monomers as replacements for petrochemical-based materials, specifically 2-ethylhexyl acrylate (2-EHA), for emulsion polymerization. While bio-sourced monomers that contribute to stiffness are more readily available, our ambitious goal is to create a bio-sourced 2-EHA equivalent, which would be a remarkable achievement in the industry. This initiative aligns with our commitment to environmental stewardship and positions Collano at the forefront of the green chemistry revolution in Switzerland. As a small, agile player in the adhesive world, our strength lies in our ability to target niche, high-performance markets with bold, innovative approaches. E.g., the global wood adhesives market, valued at $4.76 billion in 2020 and projected to reach $6.55 billion by 2027, is driven by increasing demand for eco-friendly products. Our project capitalizes on this trend, offering significant market potential and a distinctive competitive advantage.

The SmartBaler project aims to optimize waste management and reduce carbon emissions at return logistics center of large retailers by integrating ETH Zurich’s AI-driven Bale Monitoring System. This innovative solution analyzes waste bale composition in real-time, enabling improved routing, contamination detection, and recycling efficiency. By making data-driven decisions at the source, the project minimizes unnecessary transport emissions and enhances recycling outcomes. Partnering with Allegra Passugger, this initiative showcases a scalable approach to smarter resource recovery, with the potential to revolutionize waste management in logistics centers worldwide.

Generating Applications for Grensols Recycled Carbon

Grensol is revolutionizing waste management by repurposing residues from used car recycling, which traditionally end up in landfills or incinerators, leading to pollution and resource wastage. Through an innovative two-step process, Grensol first separates valuable metals and minerals for reuse, and then applies its proprietary Photolysis technology to convert remaining hydrocarbons into syngas and carbon black. This sustainable approach not only recovers high-value raw materials but also aligns with circular economy principles, reducing environmental impact while unlocking economic potential. We are also exploring ways to extend this technology to process electronic scrap and demolition waste plastics.

A key challenge for Grensol lies in finding commercial applications for the carbon black recovered from the Photolysis process, as the market imposes strict quality standards. To address this, we are testing carbon black as an additive in 3D printing polymers, allowing for direct feedback on product specifications and enabling refinement to meet industry requirements. This serves as an entry point for the material’s commercialization in small-scale applications, with the potential to scale up for broader use in injection molding and other high-volume manufacturing processes.

New class of polymeric coating solutions for CO₂ capture, transportation and storage

Carbon capture, utilization, and storage (CCUS) is expanding due to climate goals and investment opportunities. Supercritical CO₂ (s-CO₂) transportation via pipelines or vessels are the most efficient methods, but corrosion of carbon steel caused by contaminants (SOx, NOx, H2S, O2) poses a major challenge. Existing polymeric coatings are not resistant to direct contact with s-CO₂, which compromises their integrity. Azra Advanced Materials aims to develop a new class of coatings capable of withstanding long-term exposure to s-CO₂, enabling the safe and scalable deployment of CCUS solutions while supporting carbon credit certification.

Development of a synthesis process towards polyesters

Geomag and Federlegno see a unique opportunity in developing a business based on tannins in Switzerland. Tannins, a class of polyphenolic compounds found in various plants, are already used in the production of wood adhesives, offering a natural and sustainable alternative to synthetic adhesives. However, beyond these specific applications, tannins show significant potential as monomers and  copolymers for biobased polymers.

Geomag is particularly interested in tannin-based polymers for their potential to create sustainable plastic toys, enhancing the educational value of our products. The Innobooster project represents a starting point for the next generation of Geomag World magnetic toys.

Federlegno Ticino supports this challenge with the aim of encouraging new circular businesses, leveraging a Swiss value chain.

The challenge we address is the development of a synthesis process towards polyesters, overcoming uncertainties related to the polymerization costs of tannins and ensuring good mechanical properties and processability. Specific research is needed to identify the chemical route to obtain tannin-polymers at reasonable costs while maintaining high mechanical performance and workability.

Replacement of polystyrene insulation boards with pollutant-free and recyclable composites

Polystyrene insulation has long been favored for its affordability and insulating properties, but its environmental and health drawbacks are undeniable. Made from petrochemicals, its production generates high CO₂ emissions, and once used, it lingers in landfills for centuries, with recycling rarely being a viable option. Worse, large amounts of polystyrene waste end up in oceans, breaking down into harmful microplastics that threaten ecosystems and enter our food chain. Additionally, toxic flame retardants and hazardous fumes released during burning pose serious health risks. With increasing regulations and rising disposal costs, the construction industry urgently needs a sustainable alternative.

Enter mycelium-based insulation—a game-changer in green building materials. Mycelium naturally binds lignocellulose fibers from agricultural and forestry waste, creating a fully biodegradable, high-performance alternative to polystyrene. It offers excellent insulation, regulates moisture, and is inherently fire-resistant—without the need for toxic additives. Even better, it can be composted or regrown at the end of its life, aligning perfectly with circular economy principles.

The challenge now is scaling up. To compete with traditional materials, production processes must become more efficient and cost-effective while ensuring consistency at an industrial level. By overcoming these hurdles, mycelium-based insulation can revolutionize sustainable construction—offering a future where insulation is not only high-performing but also truly regenerative.

Natural flame-retardant additives for composites

Swiss CMT AG is a well-known developer of sustainable lightweight (composites) materials and processes.

In this project we are focusing on developing natural-based flame-retardant additives for our sandwich panel and part manufacturing customers. Our product idea is based on residuals from the European rice and wood industry, in which we convert Rice-Husk and Tannin-Extracts into a suitable additive that will be compounded with modern resin systems.

First independent, non-scientific laboratory trials showed some promising behaving, especially in the combination with our bio-based SolidResin system.

In the need of a large bandwidth of competences from compounding and composites characterization to fire-testing, we are confident to tackle this challenge together with specialists.

100% bio-based and biodegradable lightweight sandwich structures

Sandwich structures achieve very good mechanical properties with a comparatively low weight. This benefits the life cycle assessment of the component during the utilisation phase. If bio-based materials are used, this also has a positive effect on the CO2 balance of the component during production. However, sandwich components are a challenge for the recycling process, as the mechanical properties are achieved by permanently bonding materials with different properties together. The aim is therefore to investigate promising material combinations and, where necessary, to further develop existing materials so that simple material recycling as well as thermal recycling and biodegradability are possible in sandwich construction. Promising applications are also to be identified on the basis of a characterisation of such components.

Extraction and utilization of biopolymers from macroalgae

Open Climate Solutions wants to encourage the use of biopolymers derived from certain macroalgae in a variety of plastics applications. Macroalgae from both marine and freshwater ecosystems, such as seaweed and stonewort (respectively), can be a sustainable resource if obtained from eco-conscious operations. In addition to improving water quality and supporting biodiversity, these sources of biomass close nutrient loops and thus contribute to a circular economy, effectively turning waste into valuable goods.

Furthermore, the possibility of producing a variety of co-products from the same kilogram of biomass by splitting and cascading the input into multiple streams presents a significant opportunity for highly efficient resource utilization. Given macroalgae are already used in a variety of applications including food, nutraceuticals, pharmaceuticals and agriculture, with new uses emerging regularly, it follows that a targeted effort to process certain macroalgae obtained from sustainable sources will undoubtedly yield clever, environmentally friendly uses.

The challenge aims to explore bioprocessing methods to derive high-value biopolymers from this microalgal biomass for sustainable bioplastic production while ensuring compatibility with co-production. This holds great potential for various applications. Additionally, the challenge will identify and preliminarily test downstream processes that can utilize these components effectively.

Open Climate Solutions can provide various sustainably sourced macroalgae and would welcome the opportunity to collaborate with research partners with expertise in various processing methods to work towards solving these challenges.

Re-mediation: Recycling materials from landfill plastics

Initial situation: By 2050, the mass of plastic materials in landfills and in nature is estimated to reach 12,000 tonnes worldwide. These plastics will be removed from the material cycle and will lose value and quality if landfilled for a longer period of time. In order to make landfill remediation more economically viable, a new area of application is needed for contaminated materials as an alternative to incineration. The Tännlimoos landfill site is operated by JURA and contaminated fractions are currently being remediated. During the remediation of the landfill site, 7000 tonnes of combustible material are sorted out each year and then incinerated in a waste incineration plant. A proportion of this combustible material consists of plastics, mainly from the construction industry. These plastics cause high costs for JURA, as the calorific value of the fraction is not ideal. This is partly due to mineral contamination, but also to the high proportion of flame retardants. In this project, JURA wants to find out whether these plastic materials could be recycled.

Project content: The aim of this feasibility study is to investigate whether the production of high-quality recycled materials from landfill plastics is feasible and viable. In this project, plastic materials from the contaminated sites of the Tännlimoos landfill are to be processed in such a way that they can be reused technologically.

PHAs in Action: Putting Polyhydroxyalkanoates Under Scrutiny

Ems-Chemie is looking to expand its green portfolio. While the EMS production site is CO₂ neutral, the majority of its polymers originate from oil-based, non-renewable sources. EMS seek to rectify this across multiple different product segments:

1. Replacing current oil-based co-polyesters with CO₂neutral alternatives (target segments: powders, injection moulding and films and webs)
2. Compounding standard products with a degree of compatible bio-based/CO₂neutral alternatives to decrease the overall CO2 footprint (segments: injection moulding, films and webs)
3. Utilization of alternative bio-based or CO₂derived monomers (e.g. bio-based polycaprolactam – target material segments: automotive, adhesives)
4. Replacement of standard carbon fibres with recycled carbon fibres for metal replacing applications (e.g. Grivory HT materials 50% CF –> 50% r-CF)

EMS possesses the infrastructure needed to take this vital step, however implementation of such initiatives is problematic, especially regarding product quality consistency. EMS needs expert partners to develop solutions to these problems and evaluate their performance. With these partnerships, EMS can leverage its already established CO₂ neutral/negative production processes with innovative CO₂ negative/neutral feedstocks for a powerful environmentally conscious product range.

Development of water and grease resistand barrier coating from wood

Bloom Biorenewables has developed and scaled the aldehyde assisted fractionation (AAF) technology that allows to efficiently extract and isolate lignin from lignocellulosic biomass. The isolated lignin presents a near-native structure, meaning it is not condensed during the extraction process giving it similar properties to those lignin presents in nature. Inspired by these lignin characteristics we are developing a bio-based solution for the packaging industry inspired by nature’s natural protection mechanisms.

Grensol Group – Recycling Automotive Plastics, Without Emissions

Grensol is developing a novel solution to recycle mixed plastic waste generated during the recycling of end-of-life cars and domestic appliances. Our patent-pending photonic process essentially ‘unmanufactures’ plastic waste, breaking it down into its fundamental building blocks: carbon and hydrogen. These can then be reused as feedstock for new plastic manufacturing. This method proves especially valuable when dealing with input plastic waste that consists of mixed polymer types or is contaminated with impurities. We are thereby facilitating a circular economy for tough-to-recycle plastics. We have demonstrated the success of this approach on a laboratory scale and are now looking to scale it up for industrial use.

Antefil – Overmoulding of glass/semicrystalline hybrid fibre inserts

Antefil Composite Tech produces hybrid fibre rovings and yarns, consisting of glass filaments which are individually coated with a thermoplastic matrix material. This coating is applied in-line with the melt spinning of the glass fibre, which ensure a complete surface coverage and homogeneous distribution of the polymer on every fibre. Antefil intends to evaluate the use of such rovings as inserts for injection moulding. A previous study has yielded promising results for PMMA, even when inserting the fibres without pre-heating. A remaining challenge is to achieve a high surface quality. The proposed challenge focuses on applying this method to semicrystalline polymers and to yield high surface quality in a fast and energy-efficient process.

Treeless Pack aims to reveal the potential of nanocellulose and is constantly looking for innovative applications of its circular material.

Challenge – „Sealant“

In this call we aim to develop a silicone sealant application where the biomaterial could be applied to replace traditional fossil-based fillers such as silica and additionally benefit the final composition with improved mechanical and processing advantages. In collaboration with an industry leader in sealant development for the building materials, we seek for research partners specialized in adhesives and polymer modification and characterization.

Challenge – „Coating“

In preliminary studies we have shown our nanocellulose can be used to form a dense layer of tiny fibers which can act as a coating. Here, we look for a research partner, who would like to develop a method to deposit a coating layer on a substrate and evaluate its functionality. Furthermore, we search for industrial partners, for which a bio-based nanocellulose coating would be desired in their application.

V Carbon/Connova – rCF Honeycomb

The idea of this project is to open a new market segment for recycled carbon fibre (rCF) in the space sector by making use of a unique property: The rCF material is believed to possess a uniform thermal expansion rate in x/y/z-direction, unlike virgin continuous UD-laminate. The material could be used in composite components where thermal expansion needs to be tightly controlled, such as in space applications, particularly in honeycomb sandwich panels for satellite solar arrays. Moreover, this would be the first approach of introducing recycled composite material into the space industry.

Interested parties are warmly invited to get in touch with us!

Natural, oil-based, coatings from resourcefully grown plants such as hemp, as replacement of chemical DWR (Durable Waterproof Repellent) finishes.

Traditional PFC-based Durable Water Repellents (DWRs) pose a threat to the environment due to their persistence and potential harm to ecosystems and human health. Although PFC-free DWRs were introduced as a solution, many still rely on synthetic chemicals and pose challenges in textile recycling processes, consequently contributing to plastic pollution. Growing consumer awareness and demand for eco-friendly products are driving the need and adoption of bio-based DWRs.

This challenge focuses on developing and adopting plant-based alternatives to PFC-free DWRs within the outdoor industry. The primary goal is to reduce plastic pollution associated with outdoor apparel production by addressing the recyclability of DWR treated outdoor garments through the use of bio based alternative water repellent finishes. The biodegradable nature of plant-based DWR solutions, may also ensure more readily breakdown in the environment, reducing the persistence of outdoor materials and mitigating plastic pollution.

Objectives of this challenge include identifying oil-based, sustainably and preferably locally grown plants for water repellent characteristics, developing DWR technologies based on identified plants, defining performance and consumer adoption requirements for bio-based DWR, performance testing, evaluating biodegradability, and promoting industry-wide adoption. 

For this challenge, we would be looking to work together with experts in (bio-based) water-repellent coatings with facilities to develop new potential alternative solutions.

Full Recycling of Epoxy based Thermoset Composites

A full Composites-Recycling Technology is required to recover energy-efficiently not only the fibres,  also valuable chemical ccomponents from the cured epoxy resin.

More stringent legislation,  i.e. EU automotive directive requiring recycling quotas of 95% from the car, or the need for lowering CO2 footprints  lead to the requirement of the recycling of the polymer, not only the fibres of the composite.

Lightweight composite solutions are therefore under very high risk to be produced in Europe. So,  a significant part of our business is on risk – main portion of the resins going into composite applications are produced in our plant in Monthey, Switzerland.

Epoxy based composites are designed for longevity, exhibiting high thermal and chemical resistance (specifically the structural composite parts for airplanes such as wings, turbine blades, fuselage…) which are therefore difficult to recycle. No effective recycling solution is yet in place or proven to be commercially viable, which can be upscaled or industrialized.

Next generation sustainable coffee vending machines

Thermoplan produces market-leading coffee vending machines for corporate clients. The enormous workload places high demands on the design, materialization and construction of the machines. The next generation should be more sustainable without having to compromise on use. To achieve this, completely new concepts must be developed for the use of materials, construction methods and assembly of the machines. The goal is to significantly improve the CO2 footprint. The start is to be made with a door that must consist mainly of recycled plastic, where completely new and disruptive concepts are sought, and a clear benefit in terms of environmental impact has to be proven.

upPak Consortium

We are upPak. A Swiss based consortium committed to a common goal: to develop and implement chitosan based packaging solutions for food products.

By upcycling existing byproducts from the sea-food processing industry, we are able to divert precious raw materials from landfills and reintegrate them into the food system. Developing alternatives to PE coatings serves the environmental by reducing our dependancy on fossil fuels and phasing out micro-plastics from our supply chains.

As an abundant natural resource, second only to cellulose, chitosan bio-polymers are completely bio-degradable and can allow for seamless recycling of paper without the need for separating packaging from coating.

The core principle of our strategy is to rally critical partners along the value chain. By providing an aligned ecosystem that profits from shared-innovation and novel business opportunities, we look to achieve a truly inspiring product that will be available in market by 2026.

Ensinger Composites Schweiz GmbH – Self reinforced bio-based polymers

This forward-thinking project embarks on the mission to make composite materials more sustainable through the development of self-reinforced biobased polymers. The approach underpinning this endeavour is the concept of “self-reinforced polymer composites” (SRPCs) or “all-polymer” composites, where a polymer matrix is reinforced by means of fibres of the same polymer. The ingenious aspect of SRPCs is that they offer enhanced fiber-matrix interfacial adhesion and, more crucially, complete recyclability without the need for the arduous separation of fibre and matrix.

The project’s thematic focus revolves around creating biobased SRPCs, introducing a novel dimension to sustainable composite recycling. The capacity to use entirely biodegradable bio-sourced composite materials promises to optimise waste disposal, offering a recycling solution where none existed before. The degree of innovation here is exceptionally high.

 The impact of this initiative extends to the heart of the composite industry. As the demand for lightweight design surges, the use of traditional composites like glass and carbon fibers with thermoset matrices presents significant recycling challenges. The project’s approach opens the door to the development of 100% recyclable materials.

 Moreover, the secondary objective of developing not just bio-sourced but also bio-degradable materials shifts the need for recycling to composting, particularly vital for components where traditional recycling is impractical or uneconomical.

 The funds allocated to this project will facilitate the melt spinning of selected polymers, paving the way for critical spinning trials, fibre processing, characterization, and comparison to the requirements set by Ensinger, the project partner. This collaborative process will enable further refinements in polymer selection and process parameters, ultimately leading to the production of fibres suitable for the composite industry.

 The project is structured into work packages that include polymer selection and characterization, melt spinning of fibres, feasibility testing for self-reinforced polymer plates, and the development of process routes for textile production. Completion of WP2 and WP3 is vital in demonstrating the potential of self-reinforced polymers for composite materials.

 In sum, this project is a pioneering step towards the future of sustainable, recyclable composite materials, bringing innovative solutions to the core of the composite industry.
