Eco-Friendly Alchemy: Redefining Chemical Innovation for Sustainability
Chemicals are essential to our everyday existence. They are utilized in everything from building and transportation to food and medicine. Â
On the other hand, chemical use and manufacture also significantly affect the environment and fuel climate change. Chemical innovation for sustainability and climate action is essential to addressing these issues.  Â
To lessen chemicals’ negative effects on the environment while still addressing societal demands, chemical innovation for sustainability is required. For instance, the manufacturing of plastics is a significant contributor to greenhouse gas emissions, and the garbage produced by plastics pollutes the environment and endangers marine life. Â
The goal of chemical innovation for sustainability is to create novel materials and methods that lessen these adverse effects.Â
