A new paper published!  "Methods for Intensifying Biogas Production from Waste: A Scientometric Review of Cavitation and Electrolysis Treatments"

General trends in waste minimization stimulate the transition from linear to circular waste management systems. Therefore, developing environmentally sound biotechnologies for waste recycling and further utilization in the form of various biocomposite products and the production of biofuels is considered promising. 

Bioprocesses are usually slower than standard chemical processes. Therefore, a promising area of research is the application of microbiological methods for bioprocess intensification. 

In this publication, we have focused on searching for future research trends using microbiological methods to intensify bioprocesses in biogas production in the form of pretreatment by combinations of physical and chemical methods, such as cavitation and electrolysis.

This paper:

  1. reviews the residual area on the intensification technologies of anaerobic digestion with current methods to improve the quality and quantity of biogas.
  2. detailed review of the influence of cavitation processes on the enhancement of biogas yield is provided, as well as an overview of the simulation result depending on the type of substrate, as well as the electrolysis treatment to stimulate ecological and trophic groups of microorganisms in bioprocesses to increase biogas production.
  3. recommends focusing on the electrolysis treatment of different types of waste and their ratios with optimization of regime parameters, as well as in combination with other pretreatments to produce biomethane and biohydrogen in larger quantities and better quality.
  4. concludes that implementation methods, such as cavitation and electrolysis, stimulate biofuel production processes due to better biomass destruction, deformation of cell walls of substrate, inactivation of microorganisms, and changes in the microbial community.
