SRM Institute of Science and Technology patents paving block containing waste printed circuit board

02 February 2023

India: A team at SRM Institute of Science and Technology has patented a new concrete paving block produced using fibres from waste printed circuit board (WPCB). The refuse-derived material will replace some sand and clay in the concrete mix. SRM Institute of Science and Technology said that India generates 2Mt/yr of electronic waste (e-waste), and additionally imports this type of waste from other countries. Besides being non-biodegradable, WPCB is contaminated with colouring chemicals.

The developers said "The steadily rising volume of electronic waste poses a serious hazard to human health and the environment."

Prefer and others secure Euro4.5m in EU funding for development of carbon negative concrete blocks

19 January 2023

Belgium: The EU Innovation Fund has awarded Euro4.5m to a consortium consisting of Prefer, gas provider Fluxys Belgium, lime producer Lhoist and carbonation technology developer Orbix. The collaborators are working on a project called CO2ncrEAT. The project will carbonate steel sector by-products with captured CO2 from Lhoist's Hermalle lime plant to produce alternative building materials. CO2ncrEAT will be the first project to employ Orbix's innovative technique for the purpose. Fluxys Belgium's pipeline technology will convey the Hermalle plant's emissions over a distance of 2km to a Prefer concrete blocks plant.

The consortium said that it will use 12,000t/yr of CO2 to produce 100,000t/yr of reduced-CO2 concrete blocks. The use of alternative raw materials in the blocks will further reduce their carbon footprint by 8000t/yr.

Prefer managing director Raphaël Grimont said “As market leader, we must ensure the sustainability of our business by offering innovative and eco-friendly products to our customers. With the CO2ncrEAT project, our building materials will be produced through a sustainable and efficient process and based on local, circular raw materials. The Prefer masonry block of tomorrow will retain all the advantages of the traditional block, with the difference that it will benefit from a negative carbon footprint. We are proud to develop this exceptional project together with key industrial partners, while benefitting from the trust of the European, Belgian and Walloon authorities.”
