From giant Lego-style bricks to artificial reefs, how the construction industry is using tech to tackle climate change

Key Points

  • Renco, a composite material, was developed in Turkey to prevent manhole cover thefts and has since been used in earthquake-resistant building construction.
  • Renco blocks are lighter, have less embodied carbon, and are 100% recyclable, offering a sustainable alternative to traditional building materials.
  • The material has been used in the U.S. for the first time in 2023, with plans for local manufacturing in Florida to reduce environmental impact.
  • Sustainable timber construction is also gaining traction, with firms like Waugh Thistleton using cross-laminated timber to reduce emissions.
  • Innovative coastal construction in Monaco uses eco-friendly methods to adapt to rising sea levels and promote marine life.

Summary

The article discusses innovative approaches to sustainable construction, focusing on Renco, a composite material initially developed in Turkey to prevent manhole cover thefts. This material, which includes up to 40% repurposed materials, has been adapted for building construction, offering resistance against earthquakes and hurricanes while being environmentally friendly. Renco's introduction to the U.S. market in 2023 marks a significant step, with plans for local production to minimize the environmental footprint. Meanwhile, in the UK, Waugh Thistleton is promoting sustainable timber construction, using cross-laminated timber to significantly reduce emissions. Additionally, in Monaco, a new eco-neighborhood, Mareterra, showcases sustainable coastal development techniques, including the use of caissons to protect marine life and manage rising sea levels. These examples illustrate a broader movement within the construction industry towards sustainability, driven by the need to reduce the sector's substantial contribution to global greenhouse gas emissions.
