Special Issue Information

Dear Colleagues,

The global climate change and the demand for renewable energy pose a big challenge in the current solid waste treatment field. Thus, innovative technologies are urgently needed for energy/resource recovery from biomass waste treatment toward environmental and economic sustainability. Additionally, the biorefinery approach of recycling biomass-derived resources to replace fossil-based energy contributes to the aim of carbon neutrality. This Special Issue aims to provide a platform for global researchers to disseminate recent technological developments and engineering solutions in the areas of biomass waste treatment. Within this context, we would like to invite you to submit original research and review articles to disseminate and share new findings in energy/resource recovery from biomass wastes.

Potential topics include but are not limited to the following:

  • Anaerobic digestion;
  • Solid waste management;
  • Biofuels and biorefineries such as biogas production, biohydrogen production, life cycle assessment of biofuels, and microbial fuel cells;
  • Biomass and feedstock utilization;
  • Physicochemical and thermochemical processes for lignocellulosic and algal biomass;
  • Chemical–physical processes to recover nutrients from biomasses;
  • Nutrient recovery from biomasses: LCA and policy approach;
  • Development of innovative pretreatment methods for biomass wastes.

In recent decades, olive oil consumption has almost tripled worldwide. Olive oil production is linked with the production of enormous amounts of olive mill wastewater, the main by-product derived from three-phase olive mills. Due to the environmental risks of olive mill wastewater disposal, the management and valorization of the specific waste stream is of great importance. This work focuses on the thermophilic dark fermentation of olive mill wastewater in batch reactors, targeting pH optimization and the organic loading effect. A series of experiments were performed, during which the organic load of the substrate remained at 40 g/L after dilution with tap water, and the pH was tested in the range of 4.5 to 7.5. The maximum yield in terms of produced hydrogen was obtained at pH 6.0, and the yields were 0.7 mol H2/mol glucose or 0.5 L H2/Lreactor. At the same conditions, a reduction of 62% of the waste’s phenols was achieved. However, concerning the effect of organic loading at the optimized pH value (6.0), a further increase in the organic load minimized the hydrogen production, and the overall process was strongly inhibited.
