Special Issue Information

Dear Colleagues,

The conversion of biomass waste into high-value products represents a critical pathway toward establishing a sustainable and circular bioeconomy. Driven by the urgent need to mitigate climate change, secure energy independence, and manage escalating waste streams, biomass valorization is evolving from traditional energy generation to the sophisticated production of advanced fuels, chemicals, and materials. In this context, biomass waste, encompassing agricultural and forestry residues, municipal solid waste, food waste, sewage sludge, manure, microalgae, and industrial by-products, is recognized as an abundant and renewable resource. Key valorization pathways include thermochemical processes, biochemical routes, integrated hybrid systems that combine thermochemical processes and biochemical routes to maximize resource recovery, advanced tools such as machine learning and artificial intelligence for optimizing processes, and economic, environmental, and policy considerations.

This Special Issue, entitled “Novel Studies of Waste Biomass Conversion to Resource”, seeks high-quality research focusing on the latest novel advances in biomass conversion technology. Topics include, but are not limited to, the following:

  • Pyrolysis;
  • Gasification;
  • Hydrothermal Liquefaction;
  • Fermentation;
  • Anaerobic Digestion;
  • Machine Learning;
  • Artificial Intelligence;
  • Economic Feasibility;
  • Life Cycle Assessment.

Coastal regions concentrate livestock and fisheries activities that generate large volumes of organic residues, often managed inadequately and contributing to nutrient loading, soil degradation, and marine pollution. At the same time, these territories face increasing pressure to decarbonise energy systems and restore degraded soils under climate change. This article proposes an integrated conceptual framework for the valorisation of livestock and fisheries residues through hydrogen-centred energy recovery and biochar-based soil regeneration, with a focus on coastal regions of Colombia. The framework integrates biological and thermochemical conversion pathways, including anaerobic digestion, fermentation, gasification, and pyrolysis, within a unified system boundary that treats organic residues as secondary resources rather than environmental liabilities. Hydrogen is a transitional energy carrier enabling near-term decarbonisation within decentralised residue valorisation systems, while biochar is positioned as a key co-product enabling long-term carbon stabilisation and soil regeneration. By linking material and energy flows at the territorial scale and accounting for governance constraints and environmental vulnerabilities, the framework highlights the potential of decentralised residue valorisation systems. These systems can reduce coastal pollution, enhance soil resilience, and contribute to climate mitigation in fragile ecosystems. Full article
