Special Issue Information

Dear Colleagues,

The high living standards and population density have drastically increased the production of waste in the last few years. As a consequence, governments, companies and researchers are asked more and more to face numerous environmentally sustainable challenges, moving towards preserving resources and reusing and recycling waste. In this regard, switching from the linear model of the economy to the circular one is fundamental to developing efficient waste management processes, according to the European Commission strategies.

Despite the increasing interest of researchers, practitioners and authorities in the aforementioned issues, further efforts are still needed to find technological and economically feasible solutions to give waste materials a second useful life by reusing and recycling. Besides technical barriers, moving towards the circular economy requires new strategies and a fundamental redesign of service and products offerings, often entailing holistic adaptations in companies’ business models. In this perspective, digital technologies of Industry 4.0 may surely support the implementation of circular economy principles by enabling new business models and the redesign of value chains, products, and consumption patterns. In fact, Industry 4.0 is a manufacturing revolution embedded in a larger economic context, defined as circular, where waste gains new value by the improvement of the production systems and the redefinition of supply chains while reducing the resources consumption and the overall environmental impact.

This Special Issue calls for papers focused on the development of new uses for recycled materials (i.e., construction and demolition waste, plastics and polymers, food waste, etc.). Studies on energy efficiency and industrial solutions are also welcome. Contributions may include empirical researches, case studies, comparative and theoretical studies. Possible topics of interest include, but are not limited to:

  • Complexity, challenges, and risks in a circular economy;
  • Circular economy, social impact and digitalization;
  • The impact of 4.0 technologies in waste management;
  • Reuse and recycling of wastes;
  • Bio-based materials, bio-architecture, biomass.

In 2019, Europe adopted the New Green Deal as a strategic plan to become a competitive, resource-efficient, and driven economy by reducing its gas emissions and carbon footprint. Due the COVID-19 pandemic, this strategic plan was recently updated to expedite the green transition of European industries. Therefore, the present paper deals with the problem of deciding an appropriate size for a biomass plant that directly produces electric energy by means of two different conversion processes: combustion and gasification. After an initial estimation of the energy potential in western Sicily, GIS data of biomass growth were used to identify the appropriate size for the power plants under investigation. The economic feasibility of biomass utilization was evaluated over a capacity range of 10 to 30 MW, considering total capital investments, revenues from energy sales, and total operating costs. Moreover, the effect of variations on incentive prices was analyzed by means of a sensitivity analysis. Comparing the different plant solutions considered, the environmental sustainability was also analyzed using the life cycle assessment (LCA) approach. The results showed that the combustion solution had a higher profitability and a lower environmental impact for each plant size. The obtained results also demonstrated that providing power from residual biomass in small agricultural communities would significantly reduce their environmental impacts while improving the economic feasibility of their waste management practices.
