Special Issue Information

Dear Colleagues,

Valorization of agricultural residues to renewable energy and value-added products significantly contributes to the transition of the current agricultural production system or “productivism agriculture” era to the post-productivism agriculture or “production of nature” era. Accordingly, this issue will explore the use and management of agricultural residues as feedstock for producing renewables. It will cover various types of agricultural residues, such as crops, forestry, animal, or processing of agricultural commodities along with technologies to convert them into renewables. It will also cover deployment of renewables, including biofuels, as sustainable energy and their impact on food prices and the environment. Examples of topics that will be considered for publication are procedures to achieve satisfactory conversion results; real-world examples, and insights that promote the transition to sustainable utilization of various residues and waste products; appropriate limits and monitoring to reduce uncertainty regarding environmental benefits; and the limitations of agricultural residues to produce renewable energy. The editorial team welcomes original research articles, review articles, and case studies from researchers, academics, industrialists, and other stakeholders dealing with but not limited to the following research areas:

  • Emerging technologies of agriculture waste valorization;
  • Advances in waste-to-energy technologies;
  • Integrated sustainable waste management systems;
  • Waste based biorefineries, such as organic waste biorefinery, agricultural and   forestry waste biorefinery or integrated waste-based biorefineries, etc.;
  • Designing sustainable policies;
  • Life cycle assessment studies;
  • Circular economies and bio-based economies.

Co-firing coal and biomass in existing power plants facilitates influential advancement in the use of renewable energy resources and carbon emissions reduction. Biomass is intended as a CO2-zero net emission because, during its rise, it uses the same fraction of CO2 from the air as that released during its combustion. In addition, the content of nitrogen and sulfur in biomass is lower than in coal. Therefore, the emissions of NOx and SOx can be minimized by co-firing it with coal. In general, the effect of biomass direct co-firing on safety, pulverizing system performance, furnace efficiency, and NOx emission in full-scale furnaces is rarely studied. In this study, biomass direct co-firing was carried out in a 55 MW tangentially fired pulverized coal furnace. The effects of biomass co-firing on safety, the performance of the pulverizing system, furnace efficiency, and pollutant emissions (unburned carbon and NOx) are studied. The results show that the blending of biomass fuel with less than 20% of coal has no issue with respect to auto-ignition and safety. The performance of the pulverizing system is affected up to a certain limit due to the difficulty of grinding the biomass particles into required fineness. The biomass co-firing up to 20% is feasible, but greater than this percentage will severely affect the furnace efficiency. The co-firing of biomass enhanced the NOx reduction significantly and further improved the performance of the SNCR process. This study could provide guidance for the application of biomass co-firing in industrial furnaces. Full article
