Carbonation for agricultural use: a circular economy approach.

We investigate the application of calcium silicate materials such as basalt and steel production residues for agricultural purposes. We want to answer the question whether such an application is a technically feasible, economically viable and environmentally preferred scenario to enhance carbon sequestration (climate mitigation) and drought resistance (climate adaptation) while also providing co-benefits such as increased crop yield and nutritional value. To this end, we combine in this interdisciplinary research project three types of expertise - chemical engineering and material science, biogeochemical and ecological research, life cycle and costing analyses - to identify the most environmentally and economically desirable approach. For each of these three expertise areas, we plan novel and timely research. Through a combined iterative and interactive approach we aim to maximize the applicability of the eventual results.
