    Sustainable processes

    Aalborg Portland works to promote sustainable development in the production of cement by making extensive use of recycling of material flows from society and industries through a resource efficient cooperation.


    For example, wastes and homogenous by-products from other industries can be recycled and utilised as fuel and raw materials in cement production. This reduces overall environmental impact considerably and promotes resource-efficient production.


    We started using fly ash, a waste product from power stations, more than 30 years ago. Since then a number of other materials have been included in production.


    By recycling and by making good use of using fuels and alternative raw materials in the manufacture of cement, the wastes and by-products used are fully expended. All the constituents are consumed and no new by-products are generated.


    High temperatures and special flow conditions mean that cement kilns are well-suited to utilising alternative fuels and raw materials. In addition, filters and scrubbers inside the kiln system ensure efficient cleaning of flue gases, avoiding increased pollution.


    The Aalborg cement plant has sufficient annual capacity for the use of 700,000 tonnes of alternative fuels and alternative raw materials that can replace corresponding volumes of fossil fuels and natural raw materials which would otherwise have to be quarried in Denmark or imported.
