Industrial Carbon Dioxide Recycling

Important results from the project

The purpose of the project was to investigate the feasibility of developing competitive carbon dioxide recovery from industrial flue gases to greenhouse cultivation. The purpose and objectives have been met by a calculation being prepared for a solution for recycling and compared with other systems on the market, and with the prevailing market price for CO2. Three business models have been tested for further development, two of which remain interesting for the continued technological development.

Expected long term effects

The case study in Stage 1 shows two ways to feasibility with recycling of 3300 tons of carbon dioxide per year. The potential for domestic deliveries of carbon dioxide to greenhouses is estimated at 100,000 tonnes per year. In order to limit climate change, huge amounts of CO2 need to be captured and either stored or stored. Utilisation is the limiting factor. In order to avoid energy-intensive liquefaction and transportation, use must be made in direct connection with industries. Algae cultivation is one such possibility, preferably in combination with fish farming.

Approach and implementation

The feasibility study was conducted as a case study for application at Höganäs AB in Höganäs. The intended end customer and investor Kullatomater AB were also project partners. The project was led by WA3RM, which develops the project in Höganäs. AWA followed the project, studied the developed business models and was able to provide expert advice on IP. All parties, including consultants engaged, contributed with core competence and strong interest, which contributed to the success of the project.
