**Algimatter -- Transforming algae into sustainable materials of the future** is a pioneering feasibility project that will explore how **UK seaweed residuals** can be turned into valuable and sustainable materials with clear potential for industrial and commercial use. Seaweed is a rapidly growing sector in the UK, particularly in Scotland, where it is harvested and processed to create food ingredients, nutraceuticals, and hydrocolloids. These processes generate large volumes of fibrous residual biomass, which currently has very limited applications and is often treated as a waste stream. At the same time, UK industries such as construction, packaging, and automotive are urgently seeking alternatives to **petrochemical resins and imported natural fibres**, both of which carry high environmental impacts and face supply chain vulnerabilities. The Algimatter project will demonstrate how seaweed side streams can be **valorised** into bio-resins, biocomposites, and biodegradable films. This approach directly supports the transition to a **circular economy**, in which resources are used more efficiently and materials are designed for sustainable lifecycles. Over the course of two months, the project will: * Work with UK seaweed processors to source representative residual biomass. * Use laboratory methods to release useful fibres and polysaccharides from the biomass. * Develop and test simple **prototype samples** of bio-resins and composites. * Compare their performance with conventional materials currently used in the UK market. * Assess the environmental and economic benefits of using seaweed residuals as a new feedstock. By the end of the project, Algimatter will provide **early proof of concept** showing that seaweed residuals can form the basis of sustainable new materials. The project will also deliver a roadmap for next steps, including industrial partnerships, scale-up opportunities, and engagement with UK manufacturers seeking low-carbon alternatives. The **importance of this project** is twofold: it will help address the **waste challenge** in the seaweed sector by turning residual biomass into valuable products, and it will offer UK industries a **home-grown, low-carbon alternative** to imported petrochemicals and fibres. Importantly, this will demonstrate the potential of algae not just as a food source, but as a foundation for **new generations of sustainable materials** with applications across multiple sectors. Algimatter represents an opportunity for the UK to become a leader in algae-based sustainable manufacturing, contributing to **net-zero targets** and strengthening **resilient supply chains**. By unlocking the hidden potential of seaweed side streams, this project showcases how innovation can transform overlooked resources into the **materials of the future**.

MycoFiberTech is a pioneering initiative led by AgriCycle Innovation Ltd in collaboration with the University of York, Brunel University London, G's Mushroom Farm, EarthStar Farm, Intelligent Growth Solutions (IGS), and Saint Gobain. Our mission is to revolutionise sustainable biomanufacturing by harnessing the overlooked potential of spent mushroom substrate (SMS), a waste product from mushroom cultivation. The substrate used to grow mushrooms is a blend of organic material that becomes unusable after harvesting, often ending up in landfills. This not only causes environmental harm but also incurs significant costs for producers. Our goal is to convert SMS into high-value bio-based materials, thereby mitigating environmental impact, reducing economic burden on mushroom growers, and tapping into the potential of agricultural waste as a valuable resource. By integrating advanced biotechnological methods with innovative enzyme and twin screw extruder processes, we will repurpose SMS into high-value bio-based materials. Central to our project is the use of cutting-edge biological and twin screw extruder systems, which are scalable and controllable for extracting and refining fibers and proteins from SMS. Mycelium within the SMS leaves behind natural fibers, which are separated using enzymes and processed with biomaterial equipment. This process allows efficient extraction and refinement, creating bio-based materials with enhanced properties. By bypassing conventional, energy-intensive manufacturing methods, we not only reduce environmental impact but also promote a more sustainable production paradigm. Collaborative partnerships across the value chain are crucial to our success. G's Mushroom Farm and EarthStar Farm provide a consistent and sustainable source of SMS. End-users IGS and Saint Gobain, who have agreed to test our products, are essential in driving demand and application of our bio-based materials in vertical farming and construction sectors, respectively. Our project also prioritises smart design principles to maximise value and minimise waste. Feasibility studies and Digital Twin systems from the University of York facilitate virtual analyses of production scale-up, optimising efficiency and scalability while reducing time and costs. Through the concerted efforts of all stakeholders, MycoFiberTech aims to accelerate the adoption of bio-based materials across diverse sectors. We envision a future where agricultural waste streams are transformed into valuable resources, catalysing the transition towards a greener, more resource-efficient society. Together, we strive to foster innovation, drive sustainability, and usher in a new era of technologically advanced and resilient manufacturing practices.
