Interview: Construction chemistry in transition

In your opinion, what are the most promising developments in the field of construction chemicals?

Ana Sampaio: Promising advances in construction chemicals focus on sustainability, performance enhancement and integration with advanced technologies. 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. In addition, performance improvement plays a decisive role, with innovations such as infrared (IR) reflective materials to improve energy efficiency, and chemicals that increase durability, such as self-healing additives or advanced protective coatings. These developments support the construction industry’s drive for energy-efficient, durable and sustainable solutions, while at the same time integrating modern technologies to meet environmental requirements and satisfy consumer demand for more environmentally friendly buildings.

To what extent is the sustainability debate influencing the construction sector?

Sampaio: The sustainability debate is significantly transforming the construction industry, driving more environmentally friendly processes, materials and technologies. The growing awareness of climate change and stricter regulations have accelerated the introduction of sustainable materials and circular economy practices. The focus on a circular economy has promoted waste reduction, recycling and the reuse of materials. The circular economy can be significantly strengthened through industrial symbiosis, where waste or by-products from one sector are strategically reused as raw materials for another sector. This approach reduces waste, conserves natural resources and minimises environmental impact by creating closed loops. Converting industrial waste into valuable feedstocks not only increases resource efficiency, but also fosters innovation and collaboration between sectors. Such practices play a decisive role in promoting sustainability and support the transition to a more environmentally friendly economy.

What current challenges is the construction chemicals industry facing?

Sampaio: The construction chemicals industry faces challenges related to sustainability and technological requirements. Pressure regarding sustainability demands the development of sustainable materials, the introduction of circular economy practices and the integration of new materials and technologies to improve energy efficiency in buildings. Industry players must adopt strategies to promote the circular economy, including industrial symbiosis practices, and encourage cooperation between sectors to reuse waste as raw materials. This not only minimises waste, but also improves resource efficiency and fosters innovation in sustainable production. Furthermore, informed consumers who understand the benefits of a sustainable lifestyle can drive market shifts towards more environmentally friendly solutions. Another important challenge is the introduction of advanced technologies such as 3D printing and smart coatings, which require significant innovation and employee training. For the growth of the sector, it is crucial to balance this pressure with affordability.
