evoZero Cement is a cutting-edge material designed to achieve net-zero carbon emissions by incorporating innovative production processes. Several forward-thinking cities are interested in utilizing this sustainable cement to reduce their carbon footprint and promote eco-friendly construction practices. The construction industry is a significant contributor to global carbon emissions, primarily due to the traditional production processes of cement, a key material in concrete. In response to growing environmental concerns, innovative solutions like evoZero cement are being developed. This article explores evoZero cement, its manufacturers, the goals for net-zero carbon emissions, the technology behind its production, and the cities leading the charge in adopting this sustainable material.
Who is Making evoZero Cement?
evoZero cement is produced by Heidelberg Materials, a prominent player in the construction materials sector. Their commitment to reducing carbon footprints in the construction industry has led to the development of evoZero, a cement designed to achieve net-zero carbon emissions. Heidelberg Materials aims to cut CO2 emissions by 50% by 2030 and achieve carbon neutrality by 2050, in line with EU goals.
Goal for Net-Zero Carbon Captured Cement
The primary goal of evoZero cement is to drastically reduce, and ultimately eliminate, the carbon emissions associated with cement production. This aligns with global efforts to combat climate change and meet targets set by the Paris Agreement. By achieving net-zero carbon emissions, evoZero cement aims to transform the construction industry into a more sustainable sector, contributing to healthier environments and reducing the ecological impact of urban development.
How the Cement Production Plant Works
Cement production worldwide accounts for approximately 6-7% of all carbon dioxide emissions, most of which comes from the chemical reaction that forms the basis of the product. Approximately 65% of the carbon dioxide produced is released when limestone, the raw material, is cooked in the kiln, while the remaining 35% is released from the cooking process used to obtain the cement. The production of evoZero cement involves innovative processes that capture and store carbon dioxide (CO2) emitted during cement manufacturing. Here’s a breakdown of how a typical evoZero cement production plant operates:
- Raw Material Preparation: The primary raw materials for cement, including limestone and clay, are processed and ground into a fine powder.
- Heating and Calcination: The powder is heated in a kiln at high temperatures. Traditionally, this stage emits significant CO2. However, evoZero plants incorporate carbon capture technology that captures the CO2 before it is released into the atmosphere.
- Carbon Capture and Storage (CCS): The captured CO2 is either stored underground in geological formations or utilized in other industrial processes. This technology significantly reduces the net carbon emissions of the plant.
- Blending and Finishing: The calcined material is mixed with other compounds to produce cement. The final product is then packaged and distributed for use in construction.
Technology Behind evoZero Cement
The technology behind evoZero cement centers on Carbon Capture and Storage (CCS) and other innovative approaches such as Carbon Capture and Utilization (CCU). Here are the key technologies involved:
- Pre-Combustion Capture: This method involves removing CO2 before the combustion process, making it easier to capture and store.
- Post-Combustion Capture: CO2 is captured after the combustion process, usually from the flue gases emitted by the kiln.
- Carbon Utilization: Captured CO2 can be used to create other materials, such as carbonates, which can be integrated back into the cement production process or used in other industries.
- Renewable Energy Integration: evoZero plants often incorporate renewable energy sources, such as solar or wind power, to further reduce the carbon footprint.

Brevik CCS Plant: A Key Milestone
One of the most significant developments in evoZero cement production is the Brevik CCS plant in Norway. Due for completion in late 2024 and expected to enter production in 2025, the Brevik facility is the first large-scale cement plant to incorporate a carbon capture system. It will be able to capture and store 400,000 tonnes of CO2 per year, equivalent to 50% of the plant’s emissions. This facility sets a new benchmark for the cement industry and underscores Heidelberg Materials’ commitment to sustainable practices.
evoZero Variants and Blockchain Transparency
evoZero cement will be available in two variants:
- evoZero Carbon Captured Brevik: Delivered directly from the Norwegian cement plant, achieving a net-zero footprint over its entire lifecycle.
- evoZero Carbon Captured: Available in other countries, like Italy, leveraging CO2 savings from the Brevik plant to achieve a net-zero footprint on delivery.
The CO2 capture characteristics of both products are transparent and traceable through blockchain technology, providing verifiable proof of the carbon savings linked to the purchase of evoZero. Mechanisms for accounting for CO2 capture and emissions, such as mass balance and book-and-claim, are independently reviewed by a third-party verifier.
