Sustainable construction

By 2030, 3 billion people will need access to adequate housing globally. This translates into a demand for 96,000 new affordable and accessible housing units every day (UN Habitat). Current housing challenges are the availability or resources for construction materials, the environmental burden of the industrial activities, the logistics and cost.

Our core areas of work

With our disrupting technology, including industrialisation, new materials and the digitalisation of products and processes we will shape future dynamics in the industry.

Alternative binder technology for optimising concrete, bricks and blocks in housing

Cement is one of the most polluting and expensive materials currently used in the global construction industry. With our patented technology we develop alternative binders based on local (secondary) resources anywhere in the world. Our goal is to reduce the CO2 footprint as well as cost price of stony materials like concrete, bricks and blocks, while increasing the structural features and overall quality.

For example: in Malawi and Senegal we substitute expensive cement by local waste materials. With our local partners we develop new recipes in which firing is replaced by cold manufacturing procedures. These strong, red ‘cool bricks’ will decrease deforestation, boost the sustainable brick sector and will create employment for most vulnerable groups.

Sustainable industrialisation through new production technology

With our integrated approach including building systems, materials, production technology and project management, TNO can help construction companies to optimize modularization, off-site production automation, and on-site assembly automation. The shift toward a more controlled environment will benefit the quality, speed and sustainability of affordable housing. For example: in Ghana we are currently investigating how industrialization can benefit the production of 40.000 affordable houses for a sustainable and green new town near Accra.

TNO innovates in close collaboration with Dutch and local partners. TNO acts as knowledge partner in public-private partnerships and we develop new products, tools and approaches. In close collaborations with partners in the field we implement integrated sets of solutions. Our main partners are GiZ, RVO, Oskam ltd, LEVS Architects, Terrastone in Malawi and Elementerre in Senegal.
