Special Issue Information

Dear Colleagues,

In recent years, there is an urgent need to address the depletion of non-renewable fossil resources and their associated environmental issues with the use of fossil fuel-derived fuels. Alternatively, biomass and other organic waste materials could be promising future fuel sources. Therefore, the transformation of such materials into renewable and clean bioenergy and biofuels has attracted a great deal of attention. Even though substantial progress has been made in this field, significant challenges remain. This Special Issue is thus dedicated to focus on the research efforts regarding the technological development and advancement of clean biofuels and bioenergy production from biomass and organic waste. The relevant latest research findings including but not limited to modelling results, case studies, and critical reviews will be collected and disseminated through this Special Issue. Proposed themes include, but are not restricted to the following:

  • Pretreatment approaches for the production of clean biofuels and bioenergy.
  • Thermochemical and biological biomass conversions including pyrolysis, gasification, anaerobic digestion, fermentation, etc.
  • The computational modelling of biomass conversion technologies.

The exploration of economic and environmental aspects of bioenergy and biofuel production routes.

Amidst the growing challenges of climate change, the advancement of bioenergy in Ukraine emerges as a strategic imperative for achieving sustainable development, energy independence, and compliance with international climate commitments. As one of the key pillars of Ukraine’s economy, the agricultural sector holds vast potential for renewable energy production, utilizing both crop residues and dedicated energy crops. This study provides a comprehensive assessment of the current state and potential of agrobiomass, taking into account the destruction of infrastructure and the urgent need for soil restoration. The novelty of this research lies in its in-depth evaluation of Ukraine’s bioenergy potential under conditions of energy system destabilization and in the introduction of innovative solutions aimed at strengthening sectoral resilience. The findings highlight the critical importance of expanding bioenergy production while identifying key institutional and regulatory barriers that hinder its progress. This study proposes actionable strategies to overcome these challenges, including the adaptation of international best practices, regulatory framework enhancements, and the implementation of targeted government support programs. The insights are valuable not only for policymakers in Ukraine but also for other countries striving to accelerate the transition to renewable energy and establish sustainable decentralized energy systems. Future research directions include the development of cutting-edge biomass processing technologies, a thorough economic evaluation of bioenergy’s long-term impact on energy and environmental sustainability, and an in-depth exploration of bioenergy’s cross-border potential to enhance the energy security and resilience of the European Union.

Heavy metal pollution is posing significant threats to the environment and human health. Engineered biochar, derived from various biomass sources through thermochemical processes, has emerged as a promising solution for metal pollutant remediation and metal recovery. This review explores the latest advancements in the preparation, characterization, and application of engineered biochar for metal adsorption, recycling, and utilization. It begins by discussing the significance of metal adsorption and providing an overview of biochar properties. The review examines the preparation and characterization techniques, emphasizing feedstock selection, thermochemical conversion methods, and surface modifications. Mechanisms of metal adsorption, such as physical and chemical adsorption, ion exchange, and surface complexation, are critically discussed. Moreover, factors influencing metal adsorption capacity, including biochar properties, metal characteristics, and environmental conditions, are critically analyzed. The efficacy of engineered biochar in adsorbing specific metals, including heavy metals, transition metals, and rare earth elements, is reviewed with recent studies and key findings. Furthermore, the recycling and regeneration of metal-loaded biochar are discussed, focusing on recycling and repurposed application techniques alongside challenges and economic considerations. Finally, future perspectives are provided for the enlightening of future research. This review is unique in addressing the potential of metal-adsorbed biochar as a novel precursor to produce catalytical and electrochemical materials. Full article
