An evaluation method capable of evaluating whether or not waste plastic-derived porous carbon can be applied on an industrial scale, according to the present disclosure, may include the steps of evaluating CO2 capture performance using a 5-step temperature vacuum swing adsorption (TVSA) process, assessing economic feasibility in an industry using a techno-economic assessment (TEA) method, and quantifying environmental impacts of the porous carbon production pathway and global warming potential (GWP) using cradle-to-gate life-cycle assessment (LCA).
A method for manufacturing porous carbon, according to the present disclosure, may include the steps of carbonizing a polyethylene terephthalate plastic, activating the carbonized plastic with CO2, and performing cooling.
