The EU production of steel in 2021 was more than 150 million tons: 56% from BF/BOF route and 44% from EAF route. This process produced several million tons of residues containing iron oxide, zinc oxide and other valuable metals. 
Tenova, according to the mission to develop sustainable solutions for the steelmaking, designed a stand-alone process, that can be operated in EU steel shop, to recover the valuable elements present in the steel making residues contributing to a reduced demand of primary resources in a circular economy approach.
In the frame of Horizon EU – REMFRA project, Tenova together with Tenaris Dalmine and RINA- CSM will test at the industrial scale a Plasma Reactor for the recovery of iron oxides from different residues, implementing the use of secondary carbon carrier materials.
The Tenova Plasma Reactor is based on plasma technology (electrical arc generated by graphite electrodes) working in reducing atmosphere. This pyrometallurgical process has been selected since it can:
•	treat a large variety of waste streams: by-products coming from the steel industry (slag, scale, dust, sludge), incinerator ashes, catalyst for vanadium (V, Ni, Mo, Co), Mn-sludge, Ni-dust, Al dross and red mud.
•	use as reducing agent residuals containing C (i.e. biomass, waste polymers, petro-chemical residues)
•	accept residual containing Si (ceramic, refractory and glass).
In the paper, the status of activities and development of Plasma reactor in the frame of the REMFRA project will be presented.
