Certified green steel Renable ApS works within circular economy and process optimisation by leveraging artificial intelligence and track & trace. Our primary purpose is to create a transparent, radically open and documentable process within the recirculation of materials, starting with the dismantling and recycling of steel and other materials from the maritime industries. When the process within the maritime industries has been optimised, our method will be useful within a large segment of other industries . Our end goal is for all steps of the process of dismantling and recycling of materials to be carried out in a responsible, documentable and efficient manner, with significant reductions of both emissions and cost. The final result is green materials for green industries.
