1 Carbon Capture and Storage

One of the most promising technologies for mitigating climate change is carbon capture and storage (CCS), which involves capturing carbon dioxide (CO2) from industrial sources or the atmosphere, and storing it underground or in other forms. Chemical engineers can design and optimize the processes and equipment for capturing, transporting, and storing CO2, as well as develop new materials and methods for enhancing the efficiency and safety of CCS. For example, chemical engineers can use advanced membranes, sorbents, solvents, and catalysts to separate CO2 from flue gases, biogas, or air.

Carbon capture technologies have been available for ages now. Capturing CO2 in ammonia related solvents have always been done in process industries. Now since the world is realising the importance of CO2, the issue has become critical. Newer technologies like direct air capture is now being explored by different scientists and being studied to make it more economically viable for industries to undertake such projects as they are capital intensive.

Since I'm not a chemical engineer, I don't necessarily agree but the best way for chemical engineers (including material engineers) could be using carbon dioxide as a raw material for building materials. This way value can be created and carbon dioxide stored long term. In addition, building materials are much needed.

2 Renewable Energy

Another way for chemical engineers to address climate change is to contribute to the development and integration of renewable energy sources, such as solar, wind, hydro, biomass, and geothermal. Chemical engineers can apply their knowledge and skills in thermodynamics, kinetics, fluid mechanics, heat and mass transfer, and reaction engineering to design and improve the performance of renewable energy systems, such as photovoltaic cells, fuel cells, batteries, biofuels, and hydrogen production. Chemical engineers can also help to overcome the challenges of renewable energy storage and distribution, such as by developing smart grids, power-to-gas technologies, and thermal energy storage systems.

3 Green Chemistry

Green chemistry is the principle of designing chemical products and processes that reduce or eliminate the use and generation of hazardous substances, and minimize the environmental impact of chemical activities. Chemical engineers can adopt and promote green chemistry practices, such as using renewable or biodegradable feedstocks, designing for energy efficiency and waste prevention, using safer solvents and catalysts, and developing biocatalysis and biotechnology solutions. Green chemistry can help to reduce the carbon footprint of the chemical industry, as well as to protect human health and biodiversity.

Process needs to be developed by considering Green chemistry principles of 1) Solvent ratio optimization 2) Reduce number of extractions with increased product conversation 3) Automate effective process variable parameters controls to avoid failure and Reprocess.

4 Circular Economy

Circular economy is the concept of transforming the linear model of production and consumption, which relies on extracting, using, and disposing of resources, into a circular one, which aims to keep resources in use for as long as possible, recover and regenerate them at the end of their life cycle, and minimize waste and emissions. Chemical engineers can support and implement circular economy principles, such as by designing products and materials that are durable, reusable, recyclable, or biodegradable, developing processes that use renewable or recycled resources, applying waste-to-energy or waste-to-materials technologies, and optimizing resource efficiency and recovery.

As a chemical engineer we should look for process or ways to reduce the waste generate from chemical plants into a useful product , fir this thing to work we require help or support from government and process licensor .

5 Climate Adaptation

Climate adaptation is the process of adjusting to the actual or expected effects of climate change, such as rising temperatures, sea level rise, extreme weather events, droughts, floods, and wildfires. Chemical engineers can help to enhance the resilience and sustainability of human and natural systems, such as by developing and applying technologies that can improve water quality and availability, reduce air pollution and heat stress, protect and restore ecosystems, and strengthen infrastructure and buildings. Chemical engineers can also collaborate with other disciplines and stakeholders to assess and manage the risks and opportunities of climate change, and to plan and implement adaptation strategies and policies.
