EAF working with polymers derived from plastic residue in substitution of fossil fuel

ended

ONLYPLASTIC aims to substitute in the Feralpi Lonato EAF all the fossil carbon sources (coal, coke, pet coke), injected and charged as reducing and foaming agent, with densified polymers derived from plastic residue. To reach the optimal use of granulated SRA the following activities are foreseen: • Realization of a prototypes for granulated SRA handling and transportation • Realization of a charging system for SRA in the buckets, • Design of a new injection system customized on the granulated SRA obtained in agreement with UNI 10667-17 specifications • Investigation of the possibility to inject SRA blended/mixed with other materials, • perative practices optimization of the process with new materials. The expected benefits are: • Natural resources preservation by plastic recycling (circular economy): 100% of coal used in EAF will be substituted • Reduction of CO2 emission due to: - the contribution to iron oxide reduction reaction of the hydrogen contained in the plastic material - the reduction of specific electrical consumption (3%) • Reduction of cost index (lower cost of SRA respect to coal).
