Chemicals, materials and the products they constitute are used in ever more applications i.e. variety and volume. They are an important building block for our standard of living and improve the quality of life remarkably. Nowadays more than 100 000 – 140 000 chemical compounds are marketed in increasingly more products. A fourfold increase in the used volumes is expected at least until 2050 (OECD 2012) because of the economic growth and increasing population. Many (new) chemicals and processes will be indispensible to meet many of the United Nations Sustainable Development Goals (SDGs). Green chemistry (GC) is an important building bloc for that. It focuses on the synthesis and properties of molecules by aiming to use less energy, creating less waste and using renewable resources in synthesis and designing less toxic chemicals. However, it has been learned that there are limitations of this concept. E.g. using renewable resources is not sustainable per se as they need resources too. GC neither takes into account non-renewable resources such as metals, nor competitive usage and demands of resources and energy. Total substance and material flows linked to the products are not addressed. These issues are addressed by sustainable chemistry (SC) as well as are possible entropy transfer, rebound effects, and limitations of recycling and circular economy to mention a few. For a truly sustainable and long-term successful contribution of chemistry as a science as well as an industrial sector the framework of SC that includes green chemistry as an important building bloc is needed therefore. The concepts of GC and SC will be discussed in a broader context and examples will be given.
