Researchers around the globe are no strangers to the term “Ionic Liquids (ILs)”. With diverse applicability in chemistry, materials, chemical engineering, medicines, biochemistry to name a few, ILs are doing exactly what the researchers in the field predicted they will do, during the first international meeting devoted entirely to ILs research held on Greek grounds in Crete, back in April 2000: ILs are sustainable and decrease the environmental burden (e.g. reduce reliance on fossil fuel feedstock and replace them with renewable, increase energy efficiency, improved and/or new chemical and separation processes, etc.), while still being economically feasible in an industrial scale
