π Understanding Green Chemistry
Green chemistry focuses on minimizing the environmental impact of chemical processes and products. It's all about designing chemical products and processes that reduce or eliminate the use and generation of hazardous substances.
- βοΈ Focuses on the chemical products and processes themselves.
- π§ͺ Aims to reduce or eliminate hazardous substances.
- π± Concerned with the inherent nature of the chemistry.
π Defining Sustainable Chemistry
Sustainable chemistry takes a broader view, encompassing not only the environmental impact of chemical processes but also their economic and social impact. It aims to meet the needs of the present without compromising the ability of future generations to meet their own needs.
- π Encompasses environmental, economic, and social impacts.
- βοΈ Aims to meet current needs without compromising future generations.
- π€ Considers the entire lifecycle of a product or process.
