Seat shells made from an inventive array of new materials provide an alternative to the environmentally harmful, fossil-fuel-based plastics usually used to make injection-moulded seats.

Edinburgh College of Art graduate Spyros Kizis has designed a dining chair and a lounge chair made from artichoke thistles and bio resin. Made using a combination of plant fibre and organic epoxy resin, the Artichairs by Spyros Kizis  are completely biodegradable and can be reused as biofuel.

Designed by Jean Louis Iratzoki, the seat of Alki's new 'Kuskoa Bi' bioplastic chair is made from a 100% biodegradable and recyclable mixture of sugar cane, corn starch and beet.

Designed for Brazilian brand TOG, Industrial Facility‘s ‘Tubo’ office chair is made of shredded Coke bottles that are rolled into sheets and then hot pressed in a mold to create a shell seat with a felt-like surface.

Designed by Iskos-Berlin for Danish brand Muuto, the shell of the new sculptural Fiber chair is made of a new material composed of recyclable plastic and wood fibers.

The seat of Jonas Edvard and Nikolaj Steenfatt‘s chair is made from combination of seaweed and paper. The seaweed is harvested from the Danish coastline, before being dried and ground into a powder. Cooked into a glue, the seaweed is then combined with paper to create a material that closely resembles cork.
