Special Issue Information

Dear Colleagues,

Agricultural biomass is here thought to be the non-edible biological substances that are generated during agricultural production and produced on marginal land, including but not limited to crop residues, pruning waste, fruit and vegetable lefts, dead livestock and poultry and manure, and marginal land plants.

Agricultural biomass used to be fundamental resources for energy, feed, and fertilizer for thousands of years around the world. Currently, agricultural biomass is recognized to be a critical source of methane emission, which on the other hand could be collected in the form of advanced renewable energy to support the phasing out of fossil fuels. Further, agricultural biomass is a green source of feed, fiber, fertilizer, and soil organic matter.

This Special Issue aims to collect the most recent studies, including original research, opinions, and reviews, on the technical solutions and methods adopted for the assessment, treatment, valorization of agricultural biomass generation, in addition to technical–social–economic analyses.

The Special Issue invites submissions of papers covering a broad range of topics, including but not limited to the following:

  • Agricultural biomass generation assessment;
  • Agricultural biomass properties and characteristics;
  • Solid biofuels and utilization (pelletizing, gasification, pyrolysis, household stoves, power generation, etc.);
  • Biochar (production, field application, etc.);
  • Composting;
  • Anaerobic digestion and digestates valorization;
  • Manure acidification;
  • Field application of manure, compost, and biogas digestates;
  • Hydrothermal carbonization;
  • GHG emissions accounting and reduction;
  • Value-added utilization of agricultural biomass (feed, insect protein, single-cell protein, etc.);
  • Technical–social–economic analyses.

A Methodology for the Feasibility Assessment of Using Crop Residues for Electricity Production Through GIS-MCD and Its Application in a Case Study

Over recent decades, human activities have essentially depended on fossil fuels. The last Intergovernmental Panel on Climate Change reports recommend a shift to renewables and a more energy-efficient economy. To fulfill the potential of bioenergy, tools are required to overcome the complexities of the decision-making processes for viable projects. This work presents a decision-making tool to select the most feasible biomass residues and a case study of the state of Minas Gerais, in Brazil. Among the 13 evaluated criteria, eucalyptus residues demonstrated the highest potential for electricity production, followed by sugarcane bagasse and coffee husks. The choice of Minas Gerais as a case study is important due to its diverse agricultural landscape and the potential for biomass residue generation. The presented methodology uses the Analytical Hierarchy Process (AHP), a multi-criteria decision-making method (MCDM). Thirteen criteria were required to enable the best choice of biomass residue alternatives for electricity generation, which experts in the bioenergy field evaluated. The technical criterion was shown to be the one with the highest degree of importance. The results of the study identified that CO2eq emissions (11.46%) and electricity demand (ED) were the most relevant sub-criteria for prioritizing the viability of agricultural waste. Eucalyptus was ranked as the most promising biomass, followed by sugarcane bagasse and coffee husks. In addition, the use of GIS tools made it possible to map the regions with the greatest potential in Minas Gerais, providing a robust approach to identifying strategic sites for bioenergy.

Understanding the characteristics of biogas demand in rural areas is essential for on-demand biogas production and fossil fuel offsetting. However, the spatiotemporal features of rural household energy consumption are unclear. This paper developed a rural biogas demand forecasting model (RBDM) based on the hourly loads of different energy types in rural China. The model requires only a small amount of publicly available input data. The model was verified using household energy survey data collected from five Chinese provinces and one year’s data from a village-scale biogas plant. The results showed that the predicted and measured biogas consumption and dynamic load were consistent. The relative error of village biogas consumption was 11.45%, and the dynamic load showed seasonal fluctuations. Seasonal correction factors were incorporated to improve the model’s accuracy and practicality. The accuracy of the RBDM was 19.27% higher than that of a static energy prediction model. Future research should verify the model using additional cases to guide the design of accurate biogas production and distribution systems. Full article
