The construction industry has been hailed as one of the largest consumers of greenhouse gases, and cement is one of the key contributors to this issue. However, a breakthrough in the production of green cement has provided a promising solution to this problem. Sweden, being a global leader in the development of sustainable technologies, has been at the forefront of this revolution. Two Swedish companies, Cemvision and S:t Eriks, have signed a Letter of Intent (LoI) to supply green cement for next-generation water and sewage infrastructure solutions.
What is Green Cement?
Cemvision’s green cement is made from recycled industrial by-products from sectors such as mining and steel, instead of traditional limestone. This innovative approach reduces CO2 emissions by up to 95 per cent compared to traditional Portland cement. Moreover, it has demonstrated high durability in sewage environments and good resistance to sulphate and acid attacks.
- Reduces CO2 emissions by up to 95 per cent
- High durability in sewage environments
- Good resistance to sulphate and acid attacks
The production of green cement is an excellent example of how recycling industrial by-products can reduce waste and mitigate the environmental impact of traditional cement production.
The Importance of Water and Sewage Infrastructure
Sweden is facing significant challenges with its water and sewage infrastructure. More than 75 per cent of municipalities report a high or very high need for reinvestment in their water and wastewater facilities. In addition to its use in reservoirs and purification basins, around a quarter of pipelines, spanning over 101,000km, use concrete pipes.
| Municipalities | Need for Reinvestment |
|---|---|
| More than 75% | High or very high |
The use of concrete pipes in sewage infrastructure has severe environmental and health implications, including contamination of water sources and soil pollution.
The Partnership and Its Potential
The partnership between Cemvision and S:t Eriks is an important step toward scaling the use of climate-smart cement. Oscar Hållén, CEO of Cemvision, emphasizes the significance of this collaboration, stating: “We’re thrilled to have S:t Eriks join us on this journey. The cement applications they work with are both essential to society and in need of new, smarter solutions.”
The partnership aims to supply green cement for next-generation water and sewage infrastructure solutions, which have the potential to significantly reduce CO2 emissions and improve the overall sustainability of water and sewage infrastructure.
Key Benefits of Green Cement
The use of green cement offers several benefits, including:
- Reduced environmental impact
- Improved durability and resistance to corrosion
- Cost-effective solution
These benefits make green cement an attractive option for construction projects, particularly in the water and sewage infrastructure sector. The use of green cement has the potential to significantly reduce CO2 emissions and improve the overall sustainability of water and sewage infrastructure. As Sweden continues to face challenges with its water and sewage infrastructure, innovative solutions like green cement will be crucial in addressing these issues.
