Reverse Resources is a Software-as-a-Service (Saas) platform for major global fashion brands, their garment suppliers and recycling partners to cooperation on closing the loop for production leftovers. With making leftover information from garment factories visible online, we enable virtual traceability of fabrics through circular life-cycles from factory onwards. RR platform connects the full supply chain of textile waste from source to recycling, and all stakeholders involved in these supply chains. We enable mapping volumes of waste by composition, type and location, match it with the best possible recycling solution, build and manage efficient and transparent supply chains of delivering the waste at best cost and quality, and capture and analyse data throughout the transactions to build market insight and traceability of the material flows. We work across 10+ countries in Europe, Asia and North-Africa along and move 1000+ tonnes of textile waste each month. Through numerous large collaboration projects we interact with 30+ largest global fashion brands and all largest textile-to-textile recyclers who are producing high-end recycled textile materials already on industrial scale.
