Carbon Activated Timber Bench Bench

Press Kit

Unique Properties

The bench uses reclaimed wood planks that through their re-application continue to store carbon, since the living trees absorb CO2 from the environment. The re-use of the wood hence contributes to a positive ecological balance. Carbon is re-combined with the wood in a different state, as minimal amounts of high tech fibres that are strategically placed to enhance the capacity of the wood planks.

Dimensions & Packaging

Dimensions: 3000 x 830 x 400 mm
Volume: 0.1736 m3
Mass: 128 kg of reclaimed hardwood from outdoor deckings
Carbon fibers, total mass: 0.623 kg (around 800m of 12k carbon fibre tow)

Production Technology

The bench reflects craftsmanship in a contemporary context, where computational design and fabrication have become state of the art. After stacking reclaimed wood planks into solid blocks, an industrial robotic arm mills the blocks into their final geometries with paths for the subsequent reiforcement with fibres. The reclaimed wood planks store carbon and contribute to a positive ecological balance, whereas carbon is re-combined as minimal amounts of high tech fibres, strategically placed to enhance the capacity of the wood planks.

Design Challenge

Reclaimed wood simultaneously diverts waste and reduces the energy by forgoing the effort needed to obtain virgin materials. The finishing and fabrication contribute to making a durable, robust piece of furniture sequestering carbon for longer and reducing the need for replacements. Finally augmenting the performance of wood beyond its inherent structural capacity increases the potential range of use so it can be used differently for both industrial design and architecture.

Project Duration

Conversations started in late December 2016, and the design was completed in November 2018 and installed on the grounds of Mapletree Business City 2, Singapore

Operation Flow

Initiated by the opportunity to reuse wood decking boards the project leverages high performance materials and new techniques to renew the old materials and create a sustaining piece of furniture. An elongated pattern of tightly wound carbon fiber strands rest within robotically carved groves to hold the massive stack of blocks together. Precise, continuous curvature combined with tapered edges form a comfortable low-profile object that looks lightweight despite being 140kg

Research

The bench design highlights the expertise present in large-scale furniture carpentry in a combination of experienced labor with new forms of craft, digital calibration and robotic fabrication. By augmenting the reclaimed wood with carbon fibers, the project proves that small amounts of high-performance materials can be used alongside carbon-negative wood elements. This new design direction increases productivity and sustainability through the use of new design and manufacturing technologies.

Inspiration

Juxtaposing old, weathered hardwood with precise smooth carving and high-tech carbon fiber gives the piece a unique character. This novel expression fuses high tech carving, patina, natural wood grain, digitally designed weaving patterns and precise manufacturing. This points towards an optimized, calibrated future of sustainable design and recalls vernacular traditions of textile and wood construction. Lashing, wood joinery and timber frames act as both cultural and technological precedents.
