CO2 Derived Polyurethanes as Construction Materials for the Building Industry

The construction industry plays a pivotal role in modern life, enhancing living standards and global productivity. However, it also contributes approximately 35% of global CO2 emissions and generates 45-65% of landfill waste. To achieve Net Zero targets, it is crucial for this sector to transition from petroleum-derived resources to sustainably resourced materials.

This project aims to develop sustainable materials derived from CO2, specifically focusing on creating polyurethanes and polycarbonates for construction applications. By using Carbon Capture and Utilisation (CCU) methods, the project seeks to establish a viable industrial-scale process for producing these materials without relying on toxic or unsustainable precursors. Ultimately, it aims to facilitate the integration of sustainable products within the construction industry, contributing to a more environmentally friendly sector.

The construction industry, as well as many others, has demonstrated a strong commitment to decarbonisation. Researchers aim to develop new chemical transformations that convert CO2 into polyurethanes and polycarbonates without using toxic precursors, which require extra resources and can harm the environment.

A notable application of this research will be synthesising polyurethanes for pre-painted steels used in construction which will be of interest to Tata Steel within the Swansea Bay region.
