Evolum is a glass-cutting design studio run by Jukka Isotalo in Helsinki. Since the late 1980s, Jukka has explored the environmental side of design and art. His crockery, lamps and sculptures are made from recycled glass bottles, reducing energy and use of resources while giving each piece a new life. At Nolla, our water glasses are his design — upcycled from old beer and soda bottles, with the transformation subtle enough that you only notice if you look closely.

Helsieni grows oyster mushrooms using only local materials, like spent coffee grounds collected from nearby cafes. After harvest, the growing medium is reused or composted back into the soil. Based in Karjaa, they also run workshops, offer advice for mushroom growers, and make home kits so anyone can try growing mushrooms themselves.
