“…There are several studies on the potential of conversion of biogas into other forms of energy such as electricity. In a study conducted by (Uddin et al, 2016), biogas was presented as an alternative energy source and its impact on the Pakistani economy and healthrelated issues (dos Santos, Barros, & Tiago Filho, 2016) introduced population growth as a factor responsible (Chamy & Vivanco, 2006) for the increasing energy demand. They presented a brief method for analyzing the economic and energetic potential of the produced biogas from anaerobic wastewater treatment plants.…”

The first aim of the present study is to investigate the feasibility of the biogas production potential from Spent Mushroom Compost. Hence, its secondary aim is to study the replacement of this energy with the fossil energy source and its impact on the reduction of greenhouse gases emission. The production potential of biogas was evaluated in a laboratory-scale Open Outlet Flow Batch Type Anaerobic digester. Setups of biogas production were set at temperatures of 35°C and 55°C. Results indicate that the cumulative production of biogas at 55°C was more than that at 35°C (364.8 and 314.11 L/kg.VS, respectively). The energy required for 1 ton of spent mushroom compost in one period of production was 204.24-5.35T kW.h/ton. The amount of energy produced in a period of biogas production was calculated to be 277.95 kW.h/ton at 35°C and 322.84 kW.h/ton at 55°C. Results show that the total produced spent mushroom compost of the country is equal to 414,491.7 tons per year. Accordingly, the potential of methane production was calculated to be 8690.8 × 103 m 3 per year. It can also reduce 0.02% of the total annual production of CO 2 in Iran. ARTICLE HISTORY

“…In general, the main characteristic of POME can be shown in table 1. To be used as gas fuel, POME must be treated specifically by applying technologies such as anaerobic digestion, gasification processes, pyrolysis and carbonization [8,9,10,11]. Table 1.…”

Abstract. This research investigates the performance and emissions of an engine by biogas and gasoline. The experiments use biogas of palm oil mill effluent (POME) with turbocharger at engine loading conditions (100, 200, 300, 400, and 500 Watt). Specific fuel consumption and thermal efficiency are used to compare engine performance, and emission analysis is based on parameters such as carbon monoxide (CO), hydrocarbon (HC), carbon dioxide (CO2) and oxide (O2). The experimental data show that the maximum thermal efficiency when engine use biogas and gasoline is 20.44% and 22.22% respectively. However, there was CO emission reduction significantly when the engine using POME biogas.

“…Further research also indicates that the anaerobic digestion may generate 0.1 kWh / m 3 [3]. Reference [41] studied the economic viability for the generation of electric energy from biogas obtained in Brazilian WWTPs. A technical feasibility analysis demonstrates that it is possible to have an economic viability for the recovery of energy in a WWTP in a scale of 100 thousand inhabitants, and even smaller ones.…”

Abstract:Wastewater treatment is a process of intensive use of resources, mainly energy, which accounts for 15 to 40% of the operating costs in conventional wastewater treatment systems. With the expected demographic increase and the restrictive trend in quality standards for effluent discharge, the energy consumption tends to increase further if there are no changes in the processes. The literature gathers the energy consumption of different wastewater treatment systems, in an attempt to map the processes and to help the decision making in the search for better alternatives. One of these alternatives is the recovery of energy from the sewer. The conventional treatment system requires between 0.3 and 0.6 kWh/m 3 , while the energy contained in the wastewater may be up to 10 times of the one required for the treatment. The simultaneous wastewater treatment and power generation, called the hybrid treatment system, is a worldwide trend. In Brazil, recent studies have shown, through energy balances, the energy viability of anaerobic-aerobic systems, with the production of algae. This work presents a comparative review of the energy consumption of different wastewater treatment plants, aiming at a better understanding and management of the processes. The results showed that there are few Brazilian data published, indicating that the country still demands more studies on the subject to improve its processes. In the treatment of wastewater, most studies point to the aerobic process as the largest consumer of energy, and efforts are focused on the optimization of the conventional system, but still without great achievements. Environmental goals and water supply strategies are poorly integrated with the energy handling, leading to an inefficient use, and with economic and environmental consequences.
