Emissions of greenhouse gases, including carbon dioxide, harm the environment. Therefore, many international researchers are concerned about the use of fossil fuels. So, to prevent further irreversible climate change, it is necessary to reduce the temperature and CO 2 emissions by 2050. For this purpose, agricultural wastes are very effective and economical sources as one of the methods of CO 2 capture. The main objective of this research was to investigate the role of agricultural wastes in carbon dioxide capture and the factors affecting their performance with the aim of protecting the environment. The present research is of the type of applied research and analytical-descriptive in terms of research method. The findings showed that agricultural wastes (biomass) like bamboo wastes, olive stones, peanut shells, walnut shells, sugarcane bagasse, cottonwood, rice straw, and coffee grounds are effective in CO 2 capturing. they are also inexpensive and non-toxic, and show an adsorption capacity of up to 21 mmol/g and a surface area of up to 3900 m 2 /g. while petroleum or coal-based adsorbents have an adsorption capacity of about 160-900 mg/g and a surface area between 850-3800 m 2 /g.
