Green chemistry principles

Definition

Green chemistry principles are a set of guidelines designed to minimize the environmental impact of chemical processes while promoting sustainable practices. These principles focus on reducing waste, utilizing safer materials, and improving energy efficiency, ultimately aiming to create more environmentally friendly chemical processes. The importance of these principles extends to various sectors, encouraging innovation and reducing hazardous substances in the development of chemical products.

5 Must Know Facts For Your Next Test

1. The twelve principles of green chemistry were developed by Paul Anastas and John Warner to provide a framework for creating sustainable chemical processes.
2. Green chemistry aims to reduce the use of hazardous substances, promoting safer alternatives in chemical synthesis and product formulation.
3. Energy efficiency is a major focus; green chemistry encourages reactions that occur at ambient temperature and pressure when possible.
4. One goal is to minimize waste generation by designing chemical processes that produce little or no byproducts, leading to more efficient resource use.
5. Green chemistry also promotes the use of renewable feedstocks instead of non-renewable resources, contributing to sustainability.

Review Questions
