“…This has been reflected in the spread of home-scale solar energy use for those who can obtain it despite its high price compared to the purchasing power of the individual (Elistratov and Ramadan, 2018, Al Halabi et al, 2021 ). But surprisingly, biogas production has not received attention despite its high potential in terms of available feedstock, reducing dependence on natural gas and timber and contributing to the high need for sustainable energy in the Syrian countryside (Hasan et al, 2022 , Jafar and Awad, 2021 ).…”

In light of the massive energy supply shortage due to the Syrian war since 2011, renewable energy adoption has a high potential to cover the actual energy demand. Hence, this study aims to shed light on the factors that affect investment in biogas technology. With the scarcity of research on alternative energies in Syria, this paper focused on the characteristics of the Syrian environment toward biogas technology adoption. The results show that Syrian society accepts and desires to adopt new technologies, representing an optimal strategy to stimulate biogas technology use and the need to spread awareness about its benefits. The SWOT model was applied to identify strengths, weaknesses, opportunities, and threats facing biogas technology adoption. The analytical hierarchy process model was applied to set priorities and make better decisions related to the knowledge of biogas, acceptance of biogas technology, desire for and common approach for its use, the resulting organic fertilizer, and administrative and financial aspects. The work concludes that the southern region was at the forefront in the areas studied in terms of weights of biogas technology investment criteria, subsequently, the central and later the coastal regions. By presenting a systematic and comprehensive approach, this study represents a roadmap to assist decision-makers in inking decisions related to adopting and deploying biogas technology on a larger scale and contributes to developing a criterion for selecting biogas sites in Syria.

In response to declining electricity production in Zimbabwe, the energy regulator engaged various stakeholders to work together to solve the energy shortage problem. Biomass waste, abundant in the country, can contribute to electricity generation for consumption and export to the grid. Compared to other renewable energy resources such as wind and solar, biomass has lower investment and per unit operational costs, making it more affordable. Although farmers in the remote off-grid areas produce large amounts of waste, which can be used for biogas production via anaerobic digestion (AD), the farmers are still ‘energy-poor’. There is insufficient information to enable farmers to make informed decisions on AD technology uptake. This study conducted a techno-economic assessment for a mini biogas electric plant (MBEP) for a typical farm in Zimbabwe’s off-grid areas. The sustainably available biomass for biogas production was determined, followed by quantifying the biogas produced, sizing and selecting the digester type, and sizing the generator. The MBEP produces 435,350.7 kWh of heat and electrical energy from 452 t of biowaste. The first biodigester-type option, the garage-shaped, has a negative net present value ($$NPV$$ NPV ) of − US$416.4. The Carmatec biodigester, the most popular AD technology in the country, has a positive $$NPV$$ NPV (US$216,447.7), but its economics needs improvement. Adopting AD technology allows farmers to mitigate environmental pollution and improve soil fertility by converting organic waste into biogas and biofertilisers and promoting sustainable agricultural practices. Research was recommended to investigate supportive policies, incentives, and regulatory frameworks to promote the widespread adoption of AD technology in agricultural settings.

The present study investigated effects of coupling electrocoagulation (EC) process with an anaerobic digestion bioreactor, namely up-flow anaerobic sludge blanket (UASB), for the synthetic wastewater treatment. The EC-UASB mode of operation consisted of one anode and two cathodes subjected to an intermittent electrical current (10 minutes ON/30 minutes OFF) with current density of 1.5 mA/cm2. In light of this integration, the concentration of mixed liquor suspended solids and mixed liquor volatile suspended solids within anaerobic granular sludge (AGS) increased by 20 ± 1.4% and 12.8 ± 0.8%, respectively. The results of sludge volume index, loosely and tightly bound extracellular polymeric substances and their constituents (protein and carbohydrate) revealed that through this integration the quality of AGS has been improved. Furthermore, results of scanning electron microscopy and Fourier-transform infrared spectroscopy showed alteration in the morphology and functional groups of AGS, respectively. Additionally, this combination has demonstrated promising results in terms of performance improvement by increasing the removal efficiency of total dissolved solids by 12.1 ± 0.3% and reducing the ionic pollution in treated wastewater. However, economic analysis indicated that the optimization of operating conditions is a prerequisite of a viable economic process.
