“…In the 1970s, the Organization for Economic Co-operation and Development (OECD) proposed the "polluter pays" principle, which was officially recommended by the OECD in 1972 as a "guiding principle on the international economic aspects of environmental policies" [17]. The "polluter pays" principle [18][19][20][21][22][23][24][25] is an institutional framework designed to internalize the costs associated with mitigating negative environmental impacts. According to this principle, individuals or entities responsible for pollution at its source should bear these costs.…”

China’s sewage treatment standards have been gradually improving, yet there is a widening gap between sewage treatment fees and actual costs. This discrepancy, where the fees for sewage treatment are lower than the actual operational expenses, poses a significant bottleneck to the sustainable development of China’s sewage treatment industry. As a core aspect of environmental economic policies, sewage treatment fees are pivotal in regulating water pollution emissions and addressing water resource shortages. Currently, there are major issues with sewage treatment fees, including an incomplete pricing system, insufficient fees, unclear fee distribution, and a heavy reliance on local finances. These problems impede systematic planning, diminish management efficiency, and hinder the sustainable development of the sewage treatment industry. Thus, future research efforts should prioritize the establishment of a pricing mechanism that comprehensively covers the full cost of sewage treatment. This article presents a concise summary and review of the current situation, types of fee collection, cost accounting methodologies, challenges, and proposed countermeasures for sewage treatment fees, and could serve as a relevant reference for future research on sewage treatment fees. By comprehensively addressing these issues, the sewage treatment industry would progress towards healthier and more sustainable development, ultimately achieving the goal of green growth.

Driven by the escalating environmental impact of synthetic materials, there has been a growing focus on employing eco‐sustainable biomass‐derived biopolymers and native materials as a viable alternative to traditional energy storage applications. Biopolymer‐based energy devices, like batteries, supercapacitors, electrode materials, and ion‐exchange membranes, a novel and eco‐conscious approach, hold great potential for flexible and smart electrochemical energy storage and conversion devices, owing to their affordability, environmental sustainability, and biodegradability. This critical review outlines the sources and properties of biopolymers leading to energy storage and emphasizes their utilization in the energy sector. Despite their inherent constraints, biopolymers can be effectively leveraged when combined with other materials in composites. This collaborative approach not only refines their intrinsic physical attributes but also elevates the electrochemical performance of biologically active molecules. In this regard, bionanocomposites, a class of materials combining biopolymers and nanoparticles, have emerged as a promising greener alternative to conventional petroleum‐based polymers. Their biocompatibility, biodegradability, and antimicrobial properties have promoted their increased commercialization, thus paving the way for a more sustainable future. The review concludes by identifying and effectively addressing the limitations, challenges, and future perspectives of biopolymers in energy storage applications.

Sustainable development and the circular economy mandate efficacious management of waste. The annually increasing volumes of municipal solid waste pose a formidable global challenge. Waste-to-energy conversion, utilizing thermochemical or biochemical technologies, presents a viable solution for mitigating waste disposal concerns. This study conducts a thorough analysis of extant projects to evaluate the economic viability and environmental benefits across various technologies. Employing a self-compiled, unique database, our examination spans enterprises operational from 1980 to 2022, including 37 of the most representative facilities across Europe, North America, and East and Southeast Asia. Economic efficiency is gauged through the levelized cost of electricity generated by these installations, while environmental impacts are assessed based on the statistics on prevented greenhouse gas emissions. The methodology encompasses correlation and techno–economic analyses and expert evaluation. Contrary to conventional wisdom, our findings challenge the ubiquity of scale effects among technologies and the presumed decline in electricity generation costs with newer technologies. However, they corroborate the enhanced environmental benefits of recent technological advancements. The insights derived from this research are poised to inform strategic municipal solid waste management planning in Russia and beyond, offering a foundation for the design of new facilities. The scientific novelty of this work lies in its holistic approach to analyzing the ecological and economic efficiencies of all extant technologies.
