Patent Granted for Game-Changing CO2 Absorbing Material Made from Coffee Grounds and Plastic
Researchers at the University of Nottingham have been granted a patent for a groundbreaking technology. It converts waste coffee grounds and plastic into a material that can absorb CO2, a significant step towards combating climate change. This innovation comes at a crucial time, as there's an urgent need for sustainable solutions to reduce CO2 emissions from diverse sources.
The technology, developed by Dr. Haif Aljomard and his team at the University of Sharjah, combines two abundant waste streams - coffee grounds and plastic - to create a high-performance CO2 adsorbent. The process involves co-pyrolysis, heating the waste materials to 600°C, and activating the carbon with potassium hydroxide. The resulting activated carbon has a large surface area and a high affinity for CO2, making it highly effective for CO2 capture.
The team has tailored the technology to have a higher affinity for CO2 over other gases, ensuring its efficiency in various energy sector applications. These include solvent recovery, natural gas purification, and flue gas cleaning.
The patent for this innovative CO2-absorbing material, made from waste coffee grounds and plastic, has been granted to the University of Nottingham. This technology offers a sustainable solution to reduce CO2 emissions, turning waste products into a tool against climate change. Its versatility in energy sector applications makes it a promising addition to the fight against global warming.
