The greenhouse gas emissions during the production of anode class graphite for the conditions of Ukraine have been calculated. Conventional technologies and technologies using electrothermal fluidized bed (EFB) for natural and synthetic graphite have been studied. Calculations are carried out with respect to the whole technological chain, starting from extraction and processing of raw materials and ending with finishing processing (coating). As a result, it is shown that the technology of using EFB for purification of natural graphite and graphitization of synthetic graphite is competitive in terms of global warming potential (GWP). In the production of natural graphite using thermal purification with EFB instead of chemical purification, emissions of greenhouse gases practically remain at the same level. At the same time, the use of acids is eliminated, and the environmental impact associated with them is reduced. Production of synthetic graphite of anodic quality in EFB furnaces allows to reduce greenhouse gases (GHG) emissions by 40-50% in comparison with traditional graphitization technologies in Acheson and Kastner furnaces. The effect is achieved by reducing energy and raw material consumption.

In the context of the rising demand for electric storage systems, lithium–sulfur batteries provide an attractive solution for low-weight and high-energy battery systems. Considering circular economy for new technologies, it is necessary to assure the raw material requirements for future generations. Therefore, metallurgical recycling processes are required. Since lithium is the central and most valuable element used in lithium–sulfur batteries, this study presents an environmentally friendly and safe process for lithium recovery as lithium carbonate. The developed and experimentally performed process is a combination of thermal and hydrometallurgical methods. Firstly, the battery cells are thermally deactivated to mechanically extract black mass. Then, water leaching of the black mass in combination with using CO2, instead of emitting it, can mobilize lithium by >90% as solid product.
