Paris-based Releaf, founded by Valentyn Frechka, transforms urban fallen leaves into industrial fibres for packaging and paper. The company utilizes two proprietary processes: a dry mechanical method for filler materials and a chemical-thermal treatment to extract cellulose-like fibres. This technology allows existing paper manufacturers to integrate leaf-based materials into their current production lines without requiring new infrastructure.
The business model focuses on supplying paper to converters rather than selling raw fibres directly. Releaf partners with cities in France, Germany, Italy, and the Netherlands to source seasonal leaf waste. By processing and compacting leaves into bales, the company achieves a storage density of approximately 400 kilograms per cubic metre. Last year, the pilot line processed 1,000 tonnes of material, with plans to double this volume.
Releaf collaborates with major industrial players, including RDM Group and its subsidiary Eska, to develop materials for luxury packaging. Global brands such as Samsung, Chanel, L'Oréal, and Uber Eats have tested the company's products. In September 2026, the firm introduced a leaf-based paper laminate for premium packaging at LUXE PACK Monaco. The company is also exploring future applications in bioplastics and water-resistant coatings.
The company avoids the high capital expenditure of building its own paper mills by leveraging existing industrial capacity. According to Frechka, working with established manufacturers validates the technology and provides a clear economic case for adoption. Releaf aims to shorten supply chains for European brands by localizing production, with ongoing discussions involving luxury groups like LVMH and Kering.
