Summary: This paper introduces a new methodology that analyzes the time of recycling to compare different life cycle assessments (LCA). It incorporates the variables of material, energy, and time, as defined by the Ellen MacArthur Foundation's circularity principles. Including time in the LCA methodology enhances the understanding of the system being studied, especially for products with short usage time but long recycling time. The study presents a formula that calculates the time required to obtain secondary materials for an n+1 product. It emphasizes the need to consider the production of additional packaging products and how it depends on recycling time in order to conduct comparative LCAs between systems serving the same function.

Summary: CO2 marine geological sequestration is a crucial measure to reduce atmospheric CO2 levels and mitigate the harmful effects of global warming. Compared with traditional terrestrial geological sequestration, CO2 marine geological sequestration has greater potential, a safer distance from aquifers, and stable temperature and pressure conditions, making it safer and more efficient. This paper reviews and evaluates the main CO2 marine geological sequestration technologies and discusses their mechanisms, potential, challenges, and adverse effects on marine environments. The potential development trends in CO2 marine geological technology are also explored.

Summary: The chemical industry is striving to achieve sustainable operations within safe planetary limits, while also considering complex system arrangements and unbiased decision-making processes. Current sustainability assessment methods lack comprehensive coverage of all dimensions within life-cycle boundaries, and decision-making procedures often lack thorough evaluation of proposed techniques. Integrated systems analysis is identified as necessary for product/process life-cycle and company-levels.

Summary: Natural gas plays an important role in the transition from fossil to renewable energy sources, especially in remote offshore oil and gas fields, where its production is increasing even with high levels of CO2. This study compares the technical, economic, thermodynamic, and sustainability aspects of offshore Gas-to-Wire-CCS and onshore Gas-to-Wire-CCS solutions, both assuming post-combustion capture for enhanced oil recovery. Offshore Gas-to-Wire-CCS is found to be more sustainable and provides economic leverage through greater power generation and carbon capture benefits. Thermodynamic analysis shows the superiority of onshore Gas-to-Wire-CCS in terms of efficiency. Both solutions have positive net values after 11 years, but offshore Gas-to-Wire-CCS is better in medium-capacity and medium-terms, while onshore Gas-to-Wire-CCS is unbeatable in high-capacity and long-terms due to cheaper investment, durability, less footprint dependency, and lower cost per MWh.
