Eco‐Efficient Processing and Refining Routes for Secondary Raw Materials from Silicon Ingot and Wafer Manufacturing

Advanced Energy and Sustainability Research, EarlyView.
The ICARUS project developed pilot‐scale processes to recover and refine secondary raw materials from silicon photovoltaic (PV) ingot and wafer manufacturing waste. Silicon kerf, graphite, and silica residues are purified into high‐value inputs for the PV value chain and beyond.

Efficient Recycling of Spent LiCoO2 Cathodes Via Confined Pore‐Assisted Simplified Direct Carbothermic Reduction Without External Reducing Agents

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A simplified direct carbothermic reduction (SDCR) process is developed for efficient recycling of spent LiCoO2 cathodes. The SDCR method employs carbon conductive agents and organic binders embedded in the electrode as internal reducing agents, while the confined pores of calendered electrodes promote the retention of in situ generated reduction gases.

Effect of Intrinsic Carbon in Hot Briquetted Iron on Melting and Refining Efficiency under Electric Arc Furnace Conditions for Sustainable Steelmaking with Active Use of H2‐Reduced Iron

steel research international, EarlyView.
The melting behavior of hot briquetted iron (HBI) is observed and compared with FactSage computing simulation. When using HBI in an electric arc furnace process, a proper design of intrinsic carbon content in HBI, charging ratio of HBI, and addition of lime are proposed to be essential to control the slag volume, maintain slag basicity, and mitigate ...
