A recent study published in Heliyon has introduced a groundbreaking tool designed to assess the sustainability and circularity of biomass-based energy supply chains. This research, led by Thanh Quang Nguyen from the Department of Engineering at the University of Palermo in Italy, addresses a pressing need in the energy sector: the transition towards more sustainable and circular business models in response to climate change and resource limitations.
The study evaluates five different alternatives for biomass energy supply chains, particularly focusing on rice straw in Italy. By integrating multi-criteria decision-making methods with a life cycle thinking approach, the tool provides a comprehensive framework for companies to determine which options yield the highest sustainability and circularity benefits. “Not all the alternatives are better in terms of supporting sustainable development and circular economy,” Nguyen states, emphasizing the importance of careful selection in these initiatives.
The findings reveal that the most sustainable and circular option within the assessed supply chain is extending the lifetime of digestate from aerobic digestion plants. Conversely, capturing carbon dioxide from these plants for microalgae cultivation was found to be the least sustainable alternative. This insight is crucial for businesses looking to enhance their environmental performance while also remaining economically viable.
The implications for the energy sector are significant. As industries strive to improve resource efficiency and increase recycling rates, adopting this assessment tool could lead to more informed decision-making and better alignment with sustainability goals. Companies that implement the most effective alternatives can not only reduce their environmental impact but also potentially lower costs and enhance their market competitiveness.
Furthermore, the study highlights the sensitivity of decision-making processes, indicating that the priorities of stakeholders can influence the outcomes of sustainability assessments. This suggests that businesses should engage with their decision-makers to ensure that the chosen strategies align with both sustainability objectives and commercial interests.
As the energy sector continues to evolve, the insights from Nguyen’s research present valuable opportunities for companies to innovate and lead in the transition to a circular economy. By focusing on sustainable practices, businesses can position themselves favorably in a market increasingly driven by environmental awareness and regulatory pressures.
