The ROMEO model (Recycling Optimisation Model for Economic and Environmental Optimisation) comprises a set of physical sub-models which analyse the behaviour of our various industrial tools in the world, such as electric arc furnaces and sinter plants (steelworks used to process iron ore before it is used in the blast furnace).

It enables to simulate the effect of using a by-product (waste from the production process) to power our facilities in terms of cost, productivity and emissions.

The model provides a more efficient way to take into account economic and environmental factors when valorising by-products. Simulations can be run to improve our waste recycling. For example, the external processing of steelworks dust allows us to recover zinc and lead, which can later be reused in the steel production process. Zinc, when purified, can be used in the galvanising of flat steels such as the ones we produce at our Dudelange site. ROMEO helps the company to adopt a circular economy approach and increase its efforts to use resources sustainably.
