Resourceful Utilization Status for Decommissioned Power Batteries
With the rapid development of the new energy vehicle industry, the number of power battery decommissioning is increasing year by year. The recycling of power batteries is of great significance for protecting the ecological environment, improving the efficiency of resource utilization, and ensuring the sustainable and healthy development of the new energy automobile industry.

Residual Biomass Resources in Kazakhstan
Agricultural, animal and municipal solid waste are available to produce energy in Kazakhstan based on combustion technologies; however, animal waste and agricultural are the main potential sources with 61.02% and 38.34% of the theoretical total biomass potential energy analyses, respectively. Inadequate disposal of residual biomass can cause soil contamination, compromise the quality of water resources and promote environmental disturbances among species. As a consequence, the residual biomass before its final disposal needs to undergo an appropriate treatment process to reduce its potential environmental risk. Residual biomass from agricultural, animal and solid waste has been considered for energy production in Kazakhstan, to be incorporated into existing fuel storage and handling systems and be co-fired. Energy valorization from residual biomass would also be a key component in waste management into valuable products in a circular economy.

Renewable Energy Communities in Italy: Public Administration involvement
The pressing necessity to address climate change calls for reducing carbon emissions in the energy sector. Renewable energy communities (RECs) provide environmental, financial, and societal advantages that facilitate the shift towards sustainable energy sources.The growth of renewable energy communities (RECs) in Italy is the result of collaborative efforts from both public and private sectors, and the crucial involvement of public administrations (PAs) in promoting and expanding RECs is undeniable. A renewable energy community, especially when facilitated and supported by public administration, can be an effective solution to overcome the limitations and difficulties in implementing renewable energy sources, especially in historic and small towns.The development of RECs in Italy and the pivotal role played by public administrations as catalysts in the formation of RECs is investigated through a case study in the Municipality of Assisi.

Removal of Oil Pollutants in Soil
Oil-contaminated soil is one of the most concerning problems due to its potential damage to humans, animals, and the environment. In recent years, surfactant foam and nanoparticles have shown high removal of oil pollutants from contaminated soil. Researchers provide an overview on the remediation of oil pollutants in soil using nanoparticles, surfactant foams, and nanoparticle-stabilized surfactant foams. In particular, the fate and transport of oil compounds in the soil, the interaction of nanoparticles and surfactant foam, the removal mechanisms of nanoparticles and various surfactant foams, the effect of some factors (e.g., soil characteristics and amount, nanoparticle properties, surfactant concentration) on remediation efficiency, and some advantages and disadvantages of these methods are evaluated.

Removal of Dyestuffs from Effluents onto Biochar
Processing significant amounts of dye effluent discharges into receiving waters can supply major benefits to countries that are affected by the water crisis and anticipated future stress in many areas in the world. When compared to most conventional adsorbents, biochars can provide an economically attractive solution. In comparison to many other textile effluent treatment processes, adsorption technology provides an economical, easily managed, and highly effective treatment option.

Reductive and Oxidative UV Degradation of PFAS
Perfluoroalkyl and polyfluoroalkyl substances (PFASs) consist of a group of environmentally persistent, toxic and bio-accumulative organic compounds of industrial origin that are widely present in water and wastewater. Despite restricted use due to current regulations on their use, perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) remain the most commonly detected long-chain PFAS.

Recycling and Reuse ECOSYSTEM
Daikin Europe N.V. (DENV), Daikin Central Europe (DACE), the National Technical University of Athens (NTUA) and the Society for Materials and Energy Applications (MAT4NRG GmbH) are the four partners of the consortium behind the Retradeables project that receives EU funding. The key objective of the ongoing project is to realise the first circular economy ecosystem to strongly promote the efficient management of used gases, offering sustainability and accountability to the HVAC-R industry and reducing environmental pollution stemming from F-gas emissions. This is exactly the mission of the so-called “3R ECOSYSTEM” that is currently under development to bring total innovation to the HVAC-R industry, adding value to used refrigerants that will be treated as an asset instead of a waste to be destroyed.

Recent Advances of Perovskite Solar Cells
Perovskite solar cells (PSC) have been identified as a game-changer in the world of photovoltaics. This is owing to their rapid development in performance efficiency, increasing from 3.5% to 25.8% in a decade. Further advantages of PSCs include low fabrication costs and high tunability compared to conventional silicon-based solar cells.
