“…The removal of both CO2 and H2S from biogas through adsorption is a straightforward and effective approach. It has reported successful simultaneous and competitive removal of impurities using adsorption to enhance biogas quality and increase CH4 content [8]- [10]. Any remaining CO2 gas is absorbed by absorbers (C-101) using clean water (at a rate of 100 kg per batch).…”

The rapid growth of the palm oil industry in Indonesia has made it the world's largest palm oil producer. However, this progress comes with a challenge as the industry generates Palm Oil Mill Effluent (POME), which poses an environmental threat if directly discharged into the environment. POME contains high concentrations of organic compounds that can be harnessed to produce energy in biogas through anaerobic treatment processes. This study aims to develop an efficient POME biogas production technique for large-scale power generation. The biogas production process with a capacity of 675.38 Kg/batch, 51,9 tonnes/year, and economic evaluation were simulated using SuperPro Designer v13.0. Biogas production from POME involves a series of stages employing anaerobic microorganisms for organic material decomposition, including hydrolysis, acidogenesis, acetogenesis, and methanogenesis. The simulation results indicate that the plant can produce biogas with a composition of 86.228% methane, 1.507% water, 0.059% hydrogen, 0.016% hydrogen sulfide, and 1.959% carbon dioxide within a batch time of 114 hours. The economic feasibility simulation resulted in a Net Present Value (NPV) of $553,000, Internal Return Rate (IRR) of 19.3%, and Payback Period (PBP) of 4.22 years. Those results confirm the viability of these projects.

“…The quality of biogas has a direct influence on the calorific value of the substrate [28] Indeed, the proportion of methane is closely related to the calorific value and this is demonstrated by the calorific value formula: PCI (calorific value) = 9.42*CH4% at 15°C at atmospheric pressure. The correlation between volatile total solid (TS) and biogas richness is negative.…”

The poultry sector has grown significantly in the recent years. Certainly, the rise in the global population, particularly in developing nations, has prompted the expansion of the poultry farm sector to fulfill the growing demand for food. The activity produces organic waste and the management of which can pose problems in the farms. Poultry farming requires energy for the production processes. It is in this context this study aims to examine the energy potential of poultry waste depending where it came from (factory farm or domestic farm). The methanogenic potential of these wastes was determined using the Biochemical Methane Potential (BMP) test on poultry droppings from factory farms or domestic farms and other wastes as controls, such as cow and horse dung. The tests showed that the poultry droppings from factory farms had higher gas content and methane (CH4) than the controls. The link between biogas production and the chemical composition of the poultry droppings, was also demonstrated. These findings suggested that poultry droppings from factory farms can be used to produce biogas and/or energy. The latter can be reused for the needs of the farm itself.

“…Biogas, compared to natural gas, shows different flammability limits, meaning the range of fuel concentrations in which the gas mixture can be ignited in air and support flame propagation: due to the significant CO 2 presence in biogas (sometimes up to 50%), lower and upper flammability levels rise from 5.2% and 11.4% methane content in air (typical of natural gas) up to 10.4% and 22.8% biogas content in air (considering dry gas at 20 • C) [104]. Obviously, a higher CO 2 content in biogas negatively affects the calorific value of the biogas itself with negative impacts on the amount of recoverable energy [105]. As presented in Table 1, Imhoff and septic tanks normally show higher and variable CO 2 content than high-rate anaerobic processes, and the overall amount of biogas that is produced is limited by the fact that the process occurs at ambient temperature and by the limited size of the population served, which makes the anaerobic digestion much less profitable compared to larger-scale installations [106].…”

The present work is a critical review on the carbon footprint and energy recovery potential of septic and Imhoff tanks for primary wastewater treatment. From an online search of research papers, a lack of up-to-date research about gas emissions from Imhoff tanks emerged. Additionally, available literature data should be extended to incorporate the effect of seasonal variations, which may be relevant due to the fact that both systems work under environmental conditions. The literature generally agrees on the positive effect of temperature increase on biogas and methane production from both septic and Imhoff tanks. Additionally, sludge withdrawal is an important operational feature for gas production in these reactors. More recently, the application of electrochemical technologies and the installation of photovoltaic modules have been studied to enhance the sustainability of these decentralized solutions; in addition, sludge pretreatment has been investigated to raise the obtainable methane yields due to limited sludge biodegradability. Further research is needed to assess the effective sustainability of biogas collection and valorization from existing septic and Imhoff tanks, considering the limited biogas generation and the implementation of these systems in decentralized wastewater treatment scenarios (rural or mountain areas). Contrary to the intensive research on greenhouse gas mitigation strategies applied to centralized systems, solutions specifically designed for gas emission mitigations from septic and Imhoff tanks have not attracted the same scientific interest up to now. More generally, given the widespread application of these two options and their potential significant contribution to the overall carbon footprint of wastewater treatment technologies, much more research must be performed in the future both on the quantification of gas production and on the applicable strategies to reduce their carbon footprint.
