By 2030 we endeavor to reduce CO₂ emissions by 30% to less than 500 kg per tonne of grey cement.
In white cement, a niche product accounting for 0.5% of global cement consumption, CO₂ emissions will be lowered by 35% to around 800 kg per tonne.
Cementir Group has developed a 10-year roadmap for climate change focused on the following pillars:
- Reduction of clinker content to 68% for grey cement and 80% for white cement.
- Development of the low-carbon cement FUTURECEM TM, which allows CO2 emissions to be reduced by 30%. FUTURECEM TM is a proprietary patented technology which uses limestone and calcined clay to such an extent as to significantly reduce the amount of clinker in cement.
- Replacement of fossil fuels with alternative fuels.
- The establishment of a natural gas line to the plant located in Denmark and the installation of multi-fuel main burners for the kilns. The switching to natural gas, a fossil fuel with emissions much lower than pet coke (estimated reduction of 20% of CO₂), is a transitional solution and indispensable for Cementir’s transition to net-zero emissions. As part of this strategy, the Danish subsidiary Aalborg Portland has entered into an agreement with the local gas distribution company, Evida, to connect the Aalborg plant to the gas distribution grid on 1 April 2022.
- Technological innovation and development of special products that complete the existing portfolio, developing new business models with downstream integration projects or strategic partnerships and promoting innovative applications and products including ultra high performance concrete (UHPC), fiber reinforced concrete glass (GFRC), magnetic concrete and 3D printing.
- Energy recovery. The Aalborg plant recovers excess heat from cement production to provide district heating to local citizens. The recovered thermal energy is used to heat the homes of about 36,000 families in the city of Aalborg. In 2020, the Aalborg plant delivered about 1.8 million GJ of energy to the Municipality of Aalborg, with an annual CO₂ savings of 150,000 ton for the Municipality.
- Investments in Sustainability and Digitization. In the 2021 - 2023 Industrial Plan, we have planned green investments of 107 million euros which will generate savings of approximately 30 million euros per year once fully operational and which include, among others:
- construction of a new calcination plant aimed at the production of FUTURECEM™
- construction of a 8.4 MW wind farm for the needs of Aalborg plant;
- expansion of district heating to 50,000 families in Aalborg;
- increase in the use of alternative fuels from current 40% to 80% in Belgium;
- establishment of a natural gas line to the plant located in Denmark and the installation of multi-fuel main burners for the kiln;
- digitalization of the manufacturing process, maintenance, inventory management and spare parts in all our main plants.
- Commitment to carbon-related public policy. Cementir actively participates in global and national industry policy discussions on issues related to Climate Change, Sustainable Infrastructure, Circular Economy, Alternative Fuels, and Waste Management Frameworks, among others. Since November 2019, the Group has been involved in the most ambitious CO2 reduction project ever sponsored by a national government. In autumn 2019, the Danish government made a broad political agreement with all political parties, including one at parliamentary level about a binding climate law with the target of reducing Danish CO2 emissions by 70% by 2030 compared with the 1990 baseline. The Managing Director of Cementir’s subsidiary Aalborg Portland is leading the climate partnership for the Danish energy-intensive industry. The working group will provide the Danish government with a technical forecast of all potentially achievable CO2 reduction and will define the prerequisites (policy, research, innovation, subsidies, etc.) for such reductions.
