According to the definition of the Organisation for Economic Co-operation and Development (OECD), “Sustainable chemistry defines a scientific concept that seeks to improve the efficiency with which natural resources are used to meet human needs for chemical products and services”. It encompasses “the design, manufacture and use of efficient, effective, safe and more environmentally benign chemical products and processes”.¹  Supplementary support for this has been given by Horváth and co-workers, defining it as follows: “[R]‌esources including energy should be used at a rate at which they can be replaced naturally and the generation of wastes cannot be faster than the rate of their remediation”;^2,3  and by Welton as follows: “[A] sustainable chemical product should be supplied at a price that enables it to be accessed by its users while at the same time being commercially viable for its producers”.⁴  The concept stimulates innovation across all sectors “to design and discover new chemicals, production processes, and product stewardship practices that will provide increased performance and increased value while meeting the goals of protecting and enhancing human health and the environment”.
