“…For a 20 year operational period, the IRRs of processes INP-CC, GFP-CC, INP-ME, and GFP-ME are presented in Figure a. Among these processes, INP-CC has the highest IRR of 7%, while INP-ME obtains the lowest IRR of 4%, assuming a subsidy fee of $59 per ton . It also reveals that integration with the methanol synthesis process in INP-CC or GFP-CC reduces the IRR, with a more significant impact observed in INP-CC.…”

To address the global issue of plastic waste, the waste to wealth technique is under investigation. Four processes, known as INP-CC (incineration with carbon capture and power generation), GFP-CC (gasification with carbon capture and power generation), INP-ME (incineration with methanol and power cogeneration), and GFP-ME (gasification with methanol and power cogeneration), which include both traditional and innovative methods, have undergone development, simulation, and comprehensive comparison through techno-economic analysis. GFP-CC and GFP-ME are particularly favored for their energy efficiencies of 43.47 and 34.91%, respectively, in comparison to INP-CC (17.6%) and INP-ME (6.89%). Exergy flow diagrams reveal that the incinerator, gasifier, and combustion chamber account for over 50% of the exergy loss, highlighting their potential for intensification. However, from an economic standpoint, without a larger subsidy fee ($84 per ton) or higher methanol selling price ($550 per ton), processes GFP-ME and INP-ME are not economically attractive due to a negative net present value over 20 years. A sensitivity analysis of key economic parameters demonstrates that the price of methanol and hydrogen has the greatest impact on process economic performance. It appears that process INP-ME is more resilient in terms of economic performance when subjected to the same level of fluctuations in methanol and hydrogen prices, in comparison to GFP-ME.

“…Considering that pure PVC gasification also requires pre-separation, the high cost makes its economic efficiency low, so the LCA of the current gasification process is more inclined to the gasification of mixed plastic waste (MPW). Afzal et al 44 investigated MPW gasification to produce hydrogen and further MPW gasification to produce methanol LCA. They were compared to LCAs from fossil fuels that produce both gases.…”

Electrolyzers and fuel cells will be crucial for achieving global clean hydrogen and industrial decarbonization goals. However, the nascent clean hydrogen sector faces uncertainties around material supply chains and technology end‐of‐life management. This work aims to guide the transition to a circular hydrogen economy by using process modeling, techno‐economic analysis, and life cycle assessment to evaluate the material cost, energy use, greenhouse gas (GHG) emissions, toxicity, and water use of five potential recycling strategies for proton exchange membrane electrolyzers (PEMWE) and fuel cells (PEMFC). Hydrometallurgy, acid dissolution, and electrochemical dissolution are shown to offer 2–7 times improvement across all assessed metrics relative to the manufacturing of PEMWE and PEMFC from raw materials. Recycling can also lower the raw material demand, material cost, energy use, and GHG emissions associated with PEMWE and PEMFC deployment in the United States in 2050 by 23%, 19%, 21%, and 16%, respectively. This study provides key insights into the costs, benefits, and complexities of recycling strategies for PEMWE and PEMFC, aiding the development of a circular economy that is synergistic with clean hydrogen deployment.
