Umeå University, Nordkalk AB, and the Swedish Energy Agency reduce Swedish lime kiln emissions

A project led by Umeå University, Nordkalk AB, and the Swedish Energy Agency has reduced carbon dioxide emissions from lime kilns in Sweden by more than 36 000 tpy. The project, called ‘Renewable Energy Carriers in Quicklime Production’, was conceived to investigate and demonstrate how biofuels can be introduced as an alternative to fossil fuels in lime kilns.

The findings were that using biofuels in lime kilns can reduce carbon dioxide emissions by up to 90%. The project also found that using biofuels does not have a negative impact on the quality of the lime produced.

The project's findings have the potential to significantly reduce carbon dioxide emissions from the lime industry, which is a major source of greenhouse gases. The project's findings could also be used to reduce carbon dioxide emissions from other industries that use fossil fuels, such as the cement industry.

"The project goal is to reduce carbon dioxide emissions from non-renewable energy carriers in Nordkalk AB's quicklime production by 46 percent, which corresponds to 71 000 tons of carbon dioxide per year" says Matias Eriksson – Adjunct associate professor at Department of Applied Physics and Electronics.

"These studies evaluate the impact of biofuels on limestone, quicklime and refractory materials under controlled conditions, providing a detailed understanding of the possibilities and limitations of fuel switching" says Markus Broström, Professor at the Department of Applied Physics and Electronics at Umeå University.
