Special Issue Information

Dear Colleagues, 

In a rapidly changing planet and an ever-evolving society, the need to preserve the environment and rationally use Earth’s resources for sustainable development is more pressing than ever. The increasing volume and complexity of global waste streams have led to significant environmental impacts worldwide, making effective waste processing a critical global challenge. The rational management of waste is a critical component in that direction. This need is addressed by global waste processing technologies and treatment techniques.

This Special Issue focuses on critical review articles that are related to recycling, repurposing materials and global waste processing technologies, emphasizing on aspects such as technical performance, costs, advantages and disadvantages, operational challenges, and current research developments of these technologies at a global scale (environmental, economic and social pillars).

These technologies are rapidly evolving, with considerable advancements in waste processing and treatment technologies, including material recovery, automation and waste-to-energy solutions. Submissions that are related to key areas such as smart waste management technologies (AI-powered and machine learning-based systems, smart collection and sorting technologies, digitalized waste management approaches) and waste-to-energy technologies (e.g., pyrolysis, anaerobic digestion, gasification, incineration, etc.) for all kinds of waste streams are welcome.

These advancements in recycling and waste processing technologies are crucial for building a reliable reverse logistics network to minimize environmental impact, maximize resource recovery and address current and future global waste management challenges.

Effective management of organic wastes is essential for green and low-carbon development. Conventional technologies, including incineration, pyrolysis, hydrothermal carbonization (HTC), gasification, anaerobic digestion (AD), and composting, have supported waste reduction and basic resource recovery, but they remain limited in high-efficiency conversion and high-value utilization. This review comparatively evaluates these conventional routes together with advanced and intensified technologies, including microwave-assisted pyrolysis (MAP), plasma treatment, supercritical water gasification (SCWG), and flash joule heating (FJH), with emphasis on suitable feedstocks, performance characteristics, application boundaries, and integration potential. In general, wastes with high moisture content are more suitable for HTC, AD, and SCWG, whereas relatively dry wastes and wastes with high carbon content are more suitable for pyrolysis, gasification, plasma treatment, and FJH upgrading. The review also discusses representative integrated pathways, such as HTC-SCWG, pyrolysis and plasma coupling, AD and gasification coupling, and pyrolysis and FJH coupling, which may improve carbon conversion, broaden product portfolios, and reduce residual pollutants. However, large-scale implementation is still constrained by feedstock heterogeneity, heat and mass transfer limitations, catalyst deactivation, reactor corrosion, and system cost. Overall, no single technology is universally optimal; technology selection should depend on feedstock properties, moisture content, and target products. Full article
