Special Issue Information

Dear Colleagues,

The Special Issue "Biogenic Waste: Treatment, Reuse and Recycle" in the journal Sustainability focuses on the latest research and developments in the field of biogenic waste management and valorization. Biogenic waste covers the variety of organic waste generated all over the world, namely, municipal waste, agricultural waste, and forest and wood biomass residues. Currently, an astounding amount of biogenic waste is being generated all over the world, which is responsible for a high quantity of greenhouse gas release along with an eco-toxic impact on the environment. This large amount of waste can be turned into useful resources by employing the appropriate processing technology with a minimal impact on the environment.

The aim of this Special Issue is to provide a comprehensive understanding of the various treatment, reuse and recycle options for biogenic waste, including both technical and economic aspects. In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Biomethanation and other anaerobic digestion techniques for biogenic waste treatment;
  • Composting, vermicomposting, and other aerobic treatment methods;
  • Biogenic waste reuse in agriculture and horticulture;
  • Circular agricultural approach in residues management;
  • Anaerobic digestion-based circular economy;
  • System scale analysis of biogenic waste collection and processing chain;
  • Biogenic waste recycling in energy and material production;
  • Advanced thermal treatments such as hydrothermal treatment, pyrolysis, and gasification;
  • Life cycle assessment of biogenic waste management options;
  • Legal and regulatory aspects of biogenic waste management;
  • Sensors and modelling in waste management and renewable energy;
  • Economic and social aspects of biogenic waste management.

I/We look forward to receiving your contributions.

Anaerobic co-digestion (ACoD) of cow dung (CD) and maize cob (MC) may be envisaged as the best way to enhance biomethane formation and production of nutrient-enriched fertilizer for the implementation of a circular bio-economic system. The study aimed to find out the optimum ratio for the highest biogas production to produce heat and energy and also the generation of nutrient-enriched organic fertilizer to use in crop land. A batch study was carried out for 99 days in an incubator maintaining 35 ± 1 °C temperature for seven different test groups of CD and MC (100:0, 90:10, 70:30, 50:50, 30:70, 10:90, and 0:100). The highest biogas production (356.6 ± 21.2 mL/gVS) was at 50:50 ratio with 138.05% and 32.02% increments compared to the digestion of CD and MC alone, respectively. Kinetic modeling showed the best fit using a Logistic model to evaluate ACoD of CD and MC mathematically. ACoD of available CD and MC in Bangladesh could produce 716.63 GWh/yr electricity for consumption and a large volume of nitrogen-enriched fertilizer to use in nitrogen-deficit soil. There was no significant difference in nutrient enrichment among different test groups. Awareness about ACoD technology and proper use of digestate might bring this technology to field-level utilization and thus help to implement the circular bio-economic concept through zero waste generation.

Energy demands keep increasing in this modern world as the world population increases, which leads to a reduction in fossil fuels. To resolve these challenges, Pennisetum purpureum, an invasive grass in Brunei Darussalam, was examined as the feedstock for renewable energy through a catalytic pyrolysis process. The activated carbon was applied as the catalyst for a simple and economical solution. The catalytic pyrolysis was executed at 500 °C (the temperature for the highest biofuel yield) for both reactors to produce the highest amount of upgraded biofuels. The biochar produced from the non-catalytic and catalytic pyrolysis processes showed a consistent yield due to stable operating conditions, from which the activated carbon was generated and used as the catalyst in this work. A significant amount of improvement was found in the production of biofuels, especially bio-oil. It was found that for catalysts, the number of phenolic, alcohol, furans, and ketones was increased by reducing the amount of acidic, aldehyde, miscellaneous oxygenated, and nitrogenous composites in bio-oils. The highest amount of phenolic compounds was produced due to a number of functional groups (-C=O and -OH) in activated carbon. The regenerated activated carbons also showed promising outcomes as catalysts for upgrading the bio-oils. The overall performance of synthesized and regenerated activated carbon as a catalyst in catalytic pyrolysis was highly promising for improving the quality and stability of bio-oil. Full article
