The anthropogenic emissions of carbon dioxide and other greenhouse gases have contributed to global warming. This issue is compounded by the limited success of carbon capture projects in effectively using and storing CO2. Furthermore, excessive nitrate usage in agriculture not only leads to nutrient run-off and water pollution but also results in the production of nitrous oxide, a greenhouse gas with 300 times the global warming potential of CO2. These challenges underscore the urgent need for innovative solutions to address climate change and environmental sustainability.
Anthropogenic emission of carbon dioxide (CO2) and other greenhouse gases resulted in global warming. Carbon capture projects have little chance of success due to limited options to use and store CO2. Moreover, the excessive use of nitrate in agricultural land can result in nutrient run-off. In addition to water pollution, nitrate converts into nitrous oxide (N2O) with 300 times the global warming potential of that CO2.
Carbon+N hydrogel is cellulose-based hydrogel developed to recover nutrients from wastewater. It contains carbonate generated from carbon dioxide. It is a biodegradable hydrogel containing carbonate with a selective adsorption capacity of phosphate and nitrate.
It offers a sustainable source of nutrients and carbon credits compared to commercial fertilizers. It also releases nutrients slowly back into the soil to prevent nutrient run-off.
