World’s first carbon-neutral cement plant by 2030

Slite cement plant

HeidelbergCement to upgrade Slite cement plant on Swedish island of Gotland to capture total emissions

TODAY, HeidelbergCement have announced their intention to upgrade their facility on the Swedish island of Gotland to become the world’s first carbon-neutral cement plant. The installation at the Slite plant of HeidelbergCement’s subsidiary Cementa will be scaled to capture up to 1.8 million tonnes of CO2 annually, which corresponds to the plant’s total emissions.

Additionally, the use of bio-based fuels in cement production at Slite will be increased in line with the Group’s commitment to significantly raise the share of biomass in the fuel mix. The full-scale capturing of the plant’s CO2 emissions is targeted by 2030.

‘HeidelbergCement will be the leader in the global cement industry on its transformation path towards climate neutrality,’ said Dr Dominik von Achten, chairman of the managing board of HeidelbergCement.

‘Key for decarbonizing our industry is to find, apply and scale technical solutions for carbon capture and utilization or storage. Having gained valuable experience with CCU/S technologies in Norway and other countries, we are now excited to make the next step with a completely carbon-neutral cement plant in Sweden. This will be a game-changer for our industry.’

The breakthrough project supports Sweden’s ambitious carbon emission reduction goals. The carbon-capture facility will be built next to the existing plant in Slite, where 75% of the cement used for concrete production in Sweden is currently produced.

The authorization processes and construction period are estimated to take just under 10 years. A feasibility study, which has already been launched, will address critical issues related to technology selection, environmental impact, legal issues, financing, logistics, and energy supply. The captured CO2 will be safely transported to a permanent offshore storage site located deep in the bedrock.

HeidelbergCement are currently building the world’s first full-scale installation for carbon capture at their Brevik cement plant in Norway, with the aim of capturing 400,000 tonnes annually (50% of the plant’s emissions) from 2024 onwards.

Giv Brantenberg, general manager of HeidelbergCement Northern Europe, said: ‘Based on the positive collaboration with the Norwegian Government and other partners at our site in Brevik, we have now chosen to significantly ramp up our ambitions for a carbon-capture installation in Sweden that is four times larger. The planning for the plant in Slite will benefit significantly from the experience gained at Brevik.’
