Given the significant impact of the construction sector on global carbon emissions, prioritising sustainable and environmentally friendly chemicals has become crucial. Innovations aimed at using bio-based materials or recycled materials from the construction sector, or even from other sectors, are of key importance. These materials not only reduce environmental impact, but also align with the sector’s shift towards circular economy practices. To what extent is the sustainability debate influencing the construction sector? The growing awareness of climate change and stricter regulations have accelerated the introduction of sustainable materials and circular economy practices.
