Special Issue Information

Dear Colleagues,

The increasing demand for strategic metals, coupled with the urgent need to mitigate environmental impacts, is driving innovative research toward sustainable resource recovery from waste. In alignment with the circular economy principles promoted by European directives, there is a strong focus on minimizing waste, enhancing recycling, and preserving finite natural resources.

This Special Issue will focus on state-of-the-art recovery techniques, including pyrometallurgical, hydrometallurgical, and biological methods, evaluating their advantages, challenges, and practical applications. Additionally, the integration of waste management systems is explored as a key strategy for optimizing resource recovery and fostering a sustainable circular economy.

We invite original research articles and comprehensive reviews on innovative technologies and methodologies used for the recovery of metals and other valuable materials from solid waste. Topics of interest include, but are not limited to, the following:

  • Innovative recovery processes for extracting valuable materials from wastes;
  • Environmental and economic sustainability assessments of emerging technologies;
  • Integration of best practices in waste management systems for enhanced recovery efficiency.

Join us in contributing to the development of sustainable solutions driving the energy transition and addressing key challenges in climate and environmental sustainability.

Energy recovery technology is becoming a crucial part of modern approaches that address decarbonization, efficiency, and transitioning into a circular economy. In addition, apart from its advancements in efficiency and environmental benefits, its progress appears to be progressively limited due to its maturity and increasing complexity. In this case, innovation that focuses solely in the firm appears ineffective because more and more important knowledge in terms of innovation in processes and environmental aspects is becoming and remaining outside of organizational boundaries. In this paper, open innovation will be explored in its function as a structural innovation method of advancing energy recovery technology. The paper employs the narrative literature review of peer-reviewed literature indexed in the Scopus database to explore the implications of the outside-in model of open innovation, the inside-out model of open innovation, and the coupled model of open innovation with respect to the primary recovery processes of energy such as combustion, gasification, pyrolysis, anaerobic digestion, and landfill gas recovery. The literature incorporates findings about the implications of knowledge inflows and outflows with respect to the mentioned energy recovery processes. The results show that open innovation efficacy strongly varies according to the degree of technological maturity and performance issues, in that outside-in open innovation tends to be very effective in mature and semi-mature technology sectors, where incremental improvements in efficiency require specialized knowledge outside the industry, while coupled open innovation is crucial for addressing system-wide issues in areas such as emissions, regulatory compatibility, and infrastructure integration, while inside-out innovation is largely a means of facilitating technology dissemination and standardization once a degree of technological maturity had been realized. This study, through the association of selective open innovation practices with corresponding energy recovery technology and challenges, aims to provide a more nuanced perspective on the assistive potential of collaborative innovation in effecting sustainable development in energy recovery technology.
