Circular design exhibition — from waste to furniture.
For Melbourne Design Week 2023, we presented ‘Waste Dream’ in partnership with Mater – the Danish design company who are revolutionising circular furniture design by using green-tech processes to transform waste such as coffee bean shells, sawdust and plastic beer kegs into beautiful and sustainable furniture.
On show from 18-24 May in a garage space adjoining the Cult Melbourne showroom, this sustainability exhibition explored how different waste streams from industrial production by companies such as Carlsberg and Grohe can become new materials in the furniture industry.
Exhibition visitors immersed themselves in 70m2 of circular waste installations and discovered the design and production behind Mater’s ‘Conscious Collection’ - a series of innovative products by Børge Mogensen, Space Copenhagen, Eva Harlou and Nanna Ditzel.
Each product in Mater’s ‘Conscious Collection’ is made with Matek® - a revolutionary suite of new materials developed by Mater that takes fibrous waste material, such as coffee bean shells, fishing nets, sawdust and beer kegs, and up-cycles it into a unique composite material that can be press-moulded to create new furniture. The result is an extremely malleable material with a texture very similar to stone or marble.
The Ocean Collection was on of the key designs on show in the exhibition. Originally designed in 1955 by renowned designers, Jøgen and Nanna Ditzel in wood, Mater has reimagined the range in recycled materials. In a nod to its materiality, the Ocean collection is largely made from ocean plastic waste - one of the most important issues facing our planet. A new innovative business model motivates fishermen across the world to dispose of their discarded fishing nets. One Ocean bench uses 3.2kg of ocean plastic waste.
More recently, Mater launched the Ocean OC2 Collection, with slats made from plastic beer kegs from Carlsberg, one of the leading breweries in the world. When the beer kegs are emptied after use, they get deflated, granulated and cast into the characteristic green coloured slats of the Ocean OC2 Collection.
Working with Waste.
Driven by a circular-economic approach to production, Mater uses green technology to upcycle waste streams and produce innovative and sustainable furniture solutions. Exhibition visitors were able to see how these waste streams are upcycled by Mater to produce sustainable furniture.
Green Technology Materials include:
- Industrial plastic waste: Left over industrial waste from GROHE is granulated into small plastic pieces.
- Coffee shells: Discarded shells from BKI Kaffe's coffee bean roasting process.
- Beer kegs: Empty plastic beer kegs from Carlsberg are crushed and made into ready-to-use plastic granules.
- Spent grain: Spent grain waste from Carlsberg brewery.
- Mango wood: Harvested trees that would otherwise be burnt or left to break down.
- Discarded fishing nets: Collected from the ocean, shredded, cleaned and made into plastic pellets.
- Sawdust: Discards collected from the construction of wooden furniture.
We were delighted to welcome Ole Bjerg from Mater, who hosted a series of guided exhibition tours throughout the week.
Visitors were taken on a personal journey through the exhibition to learn how Mater is changing the way sustainability can be achieved in the furniture industry.
