Decoupling environmental impacts from the energy-intensive production of cement: the case of Aalborg Portland


30.10.2018 kl. 13.00 - 16.00


Through the case of Aalborg Portland, this dissertation explores opportunities for an
energy-intensive industry in Denmark to decouple its operations from the use of nonrenewable
resources and direct greenhouse gas (GHG) emissions and thereby sets
emission-reduction targets for 2030.

Guidelines are provided to reach those emission-reduction targets through the use and
distribution of by-products while keeping environmental impacts beyond the factory
gates to a minimum. Findings show that using by-products within cement production
and optimizing the distribution of excess heat is an effective way to reduce process and
fuel emissions. However, this should be done with a good understanding of the
markets. Because the availability of a by-product cannot adjust to the demand for it and
because competition for good alternatives to virgin resources has increased, attention
must be paid to reduce environmental impacts beyond the factory gates that may
occur by way of demand displacement. Besides the use and distribution of by-products,
increasing cement strength and investing in renewable energy also provide a significant
reduction in GHG emissions.

More generally, this dissertation reflects on the role of life cycle assessment to support
energy-intensive industries as they are pressed to find alternatives to the use of nonrenewable
