“…There has been a great effort to reduce exhaust emissions from the diesel engine burning of fossil fuels . Accordingly, many studies provide various solutions to these threats . Heavy dependence on fossil fuel and high production volume of pollutants and wastes and mismanagement of these pollutants and limit refinement of nature have caused environmental crisis .…”

The aim of present study is to develop an accessible accurate estimation of CN based on fatty acid methyl esters and to provide a proper solution for presenting a user‐friendly method. In fact, this study calculates the density, viscosity, and HHV based on FAMEs and predicts the CN by employing fuzzy method within a set. This is an interesting approach that has not been used in similar articles. Gaussian membership functions with 81 roles were employed to develop the fuzzy model. The model was developed based on Carbon number, Double bond, Saponification number, and Iodine value to predict the CN. Performance factors of r, RMSE, MAE, and R2 were calculated as 0.9912, 1.0723, 0.63427, and 0.9828, respectively to predict the CN. The results of FAMEs effect on properties of biodiesel showed, increasing Carbon number of FAMEs increases the CN, viscosity, and HHV, but increasing the number of Double bonds decreases CN, viscosity, and HHV. While the effect of increasing Carbon number of FAMEs on density was vice versa. Based on results, C16:00, C18:00, C18:1, and C18:02 FAMEs are approximately in components of all conventional oils; therefore, they can be effective on physical properties of biodiesels. © 2019 American Institute of Chemical Engineers Environ Prog, 38: 584–599, 2019

“…In today's world, fossil fuels reign over the global energy systems. But, due to the reduction of resources of non-renewable energy, and the pollution and environmental damage that has been caused, the world is turning towards renewable energy sources (Afsharzade et al, 2016) . In this study, Figure 1 indicates the total energy consumption in Iran and across the world (Hamzeh, Ashori, Mirzaei, Abdulkhani, & Molaei, 2011;Mostafaeipour & Abarghooei, 2008;Najafi, Ghobadian, Tavakoli, & Yusaf, 2009).…”

“…Iran, in addition to having different sources of fossil energy, also has various renewable energy resources (Bahrami & Abbaszadeh, 2016). Such resources that have been discussed by researchers include solar energy (Afsharzade et al, 2016), wind energy (Mostafaeipour & Abarghooei, 2008), hydropower energy (Derakhshan & Nourbakhsh, 2008;Ghorashi & Rahimi, 2011), biomass (Afazeli, Jafari, Rafiee, & Nosrati, 2014;Noorollahi, Kheirrouz, Asl, Yousefi, & Hajinezhad, 2015), and geothermal energy (Bahrami & Abbaszadeh, 2013;Noorollahi, Yousefi, Ehara, & Itoi, 2008).…”

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

Continued reductions in air pollution and greenhouse gas (GHG) emissions are crucial in megacities like Tehran, Iran, as they pose serious threats to both people's health and the environment. Reducing energy use through renewable energy projects will result in the mitigation of GHG emissions. Hence, this study was designed to assess the use of renewable energy resources to provide the energy services for a residential building. The specific objective of this article is to select a hybrid renewable energy system that can meet the energy demand of a 5‐story residential building in Tehran. The energy consumption of the building is calculated using DesignBuilder software. Then, HOMER software is applied to propose an economically feasible solar‐wind hybrid system that can meet the energy demand of the building. Initially, information required for HOMER and DesignBuilder software such as the building plan, details on electrical appliances used in the building, solar radiation, wind speed, and cost of renewable systems were collected. Subsequently, the energy performance of the building was simulated in DesignBuilder software and the results were applied to HOMER software. Finally, the hybrid systems proposed by HOMER were economically compared. Furthermore, the emissions produced by the proposed system were evaluated against a diesel only system to assess the amount of offset emissions. The comparison of the hybrid and diesel systems shows that utilization of hybrid systems can significantly reduce the magnitude of GHG emissions along with achieving cost saving. © 2019 American Institute of Chemical Engineers Environ Prog, 38:e13146, 2019
