Materials

At the heart of Rento is a commitment to materials that withstand time, gaze, and ethical consideration. We focus on continuous product development, reducing packaging, and increasing the use of recycled materials.

Aluminium

Light, strong, and corrosion-resistant. While energy-intensive to produce, it can be recycled basically forever, a process that works exceptionally well in Finland.

Bamboo

A fast-growing plant requiring minimal water. Our heat-treated, laminated bamboo is light and durable, staying beautiful for years with proper care.

Biocomposite

Made from DuraSense™ by Stora Enso, containing 40% wood fibre from Nordic forests. Designed for longevity and can be reused up to seven times.

Recycled cotton

Our textiles utilize surplus cotton from the textile industry, collected in mills and processed back into high-quality fiber.
