Accra based non-profit organisation The Or Foundation will unveil recycled textiles platform Foose Materials for the first time publicly as part of London Design Festival. Showcasing at Material Matters, an annual design event and trade show focused on the vital role that materials and sustainability play in architecture, craft, and design, Foose Materials will introduce two new recycled material lines alongside products developed using these materials.

Cassaboard and Tarnty are innovations of The Or Foundation’s Material Technology and Transformation Lab (MTTL), where a team of engineers, designers and citizen scientists have been developing material pathways that divert  post-consumer garment waste collected at Kantamanto Market in Accra.

Cassaboard is a recycled biocomposite made from post-consumer textile waste. The unsold and discarded textiles are shredded and blended with cassava-based binders—a natural and locally abundant resource – transforming them into a fiberboard material suitable for various interior building applications. The material’s superior sound absorption properties make it the perfect base material for the Foose Acoustics line featuring bookshelf speakers and geometric acoustic panels. The bright colours in each piece are drawn entirely from the recycled textiles, meaning no additional dyes are used throughout the process.

Tarnty is a circular t-shirt yarn made from unsold t-shirts sourced in Kantamanto Market. Developed in response to the volume of low-quality, single-use t-shirts- merchandise produced for conferences, company events, marathons, and hen dos-flooding the secondhand market, each ball of Tarnty is made from one t-shirt. The yarn is suitable for knitting, crochet, weaving, and other crafts. The yarn will be showcased alongside woven products, including traditional cloth and garments made in collaboration with weaving communities in Northern Ghana.

Kantamanto is one of the world’s largest secondhand clothing markets, receiving approximately 15 million used garments each week, exported primarily from the UK, Europe, and North America. The rise of the fast fashion business model, which prioritises volume over value, resulting in declining garment quality, has left countries such as Ghana at the receiving end of a mounting waste crisis, visible in mountainous landfill piles, clogged waterways, and beaches littered with discarded clothing.

While this crisis has been widely documented, less attention has been paid to the solutions being developed by affected communities on the ground. Through Foose Materials, The Or Foundation aims to divert waste and create new value streams while reducing debt, remediating landscapes and generating dignified work for the Kantamanto community.
