Through the understanding that there is 50% to 80% of timber wastage during manufacturing, london-based designers marjan van aubel and jamie shaw have investigated ways of incorporating waste shavings into design using bio-resin. A curious chemical reaction occurs when they are mixed with the scraps, expanding it into foam.

The reaction is exacerbated by different types of wood, the addition of water, air trapped in material, and increased temperatures these different factors can give expansion of up to 600-700%.

By adding colour dye and varied-sized shavings from different workshop machines, a colourful, lightweight and mouldable material is created, reinforced by the fibres in the hardwood discards. A porridge-like mixture the formed material is slapped on to the underside of the chair shell by hand, building up the material wherever extra strength was required.

The mixture then foamed explosively to create its own exuberant form, anchored by the simple turned legs of american ash.
