A Brave New Hub for Building Material Reuse | Lucas van Laack and Sunniva Baarnes

A Brave New Hub for Building Material Reuse

Recycling gets a lot of attention in the circular economy, but reuse is just as important, and consumes significantly less energy. Lucas van Laack and Sunniva Baarnes introduce Rehub, a new online platform enabling builders to search for reusable materials across multiple marketplaces and databases.


The demand for global housing is exploding. Meeting that demand with current construction processes and new materials will increase resource use by 85% by 2060, just at a time when we need to be reducing consumption. Innovation is required. Enter Rehub, an online hub created by the global engineering consultancy Rambøll. Rehub enables builders to search for and purchase reusable building materials in their area. The roof tiles from one building can become wall materials in another, the timber from a tear-down can become cladding in something new, drastically reducing environmental impact in the process. Rambøll’s Lucas van Laack and Sunniva Baarnes introduce you to the possibilities of the platform.

Bamboo Transcends the Tropics for Carbon-Negative Construction

Bamboo is not an easy material to work with—its odd shape, thickness, and segment lengths make it difficult to mill and join together. But it has one very important factor that overrides all of that: its negative carbon footprint. Combine that with how fast it grows, and designers are taking a hard look at bamboo as a building material of the future. This Redshift article by Zach Mortice breaks down what’s being done with bamboo, and shows some promising examples from the field.

Opportunities and Risks of Material Innovation in a Developing Construction Industry

In the developing world, fragile supply chains, lack of standardization, and limited training in construction practices often prevent locally-sourced sustainable materials from being used. MASS Design Group is aiming to change that by creating opportunities to strengthen the construction industry in East Africa. James Kitchin leads this AU Las Vegas 2019 industry talk featuring case studies that will help you innovate with materials across the world.
