The government has put the spotlight on how Danish companies can boost the growth of green business models and better use of resources. One possibility for the industrial sector is to replace the use of fossil fuels such as coal and oil in production with alternatives. Ph.D. student Ernst-Jan Prosman is currently busy investigating a specific alternative of immense potential benefit.
Prosman has taken the saying “one man’s trash is another man’s treasure” quite literally, as his approach is to use the leftovers of recycling companies: waste which is otherwise landfilled. This waste has several potential applications, amongst others generating heat for cement production.
However, this requires some serious collaboration between the recycling companies and the company receiving the waste, as this combination and the handling and preparation of the waste is crucial to whether the company is able to use it in its combustion plant.
“It involves a long and complex process to ensure that the waste which a company generates can used by another company. It requires a close collaboration, and this is where I can help by optimising the supplier’s production for the purpose of increasing the quality of the waste product, which is subsequently bought and used by Aalborg Portland,” explains Prosman.
This has shown great potential so far and the results are already starting to show. Last year alone, alternative fuels accounted for 45% of the total fuel consumption by Aalborg Portland in the production of grey cement.
