Evaluation of Emission Sources and Strategies for Reducing GHGs in Hamedan Province Industries with Fossil Fuel Consumption Approach

Industry is one of the five main sectors that contribute to greenhouse gases (GHGs) emissions in the country. Given Iran's voluntary commitments in the Paris Agreement to reduce GHGs emissions, it is essential that the Ministry of Industry, Mines and Trade (MIMT), through affiliated organizations in the provinces, identify industrial units with high emissions of GHGs and operational strategies to reduce emissions and notify these units.
In this research, fossil fuel consumption was used to identify industrial plants with high GHGs emissions in Hamadan province. To estimate the share of different industries in the province, from each industry, some active factories were visited randomly. During the visits, the production process and other possible emission sources of each industrial plant were studied.
Cement production units, with an emission of 76,100 tons, and brick and ceramic and porcelain product production units, with a total emission of 19,440 tons, are the major GHGs emitting industries in the province. The main source of direct GHGs emissions in various industries in Hamedan province is fossil fuel consumption, with a share of about 67%. Therefore, the main strategies for reducing emissions are to reduce fossil fuel consumption in these industries.
In order to reduce GHGs emissions, low-cost solutions should be used in the short term, such as optimizing the recycling of thermal energy from hot gases resulting from combustion, and in the long term, expensive solutions should be used, such as replacing traditional furnaces with advanced and fully intelligent furnaces and renovating steam boilers.
