Abstract
The philosophy of chemical engineering and the realization of a sustainable society is discussed. According to our goals of achieving a sustainable society and for supporting our population, it will be paramount to evolve to solar energies. Proper training and education will help to establish new identities for chemical engineers, who will make up a broad discipline of sustainability engineering. One of the challenges for chemical engineers will be to design systems for chemical recycle that are truly compatible with the environment. In chemical processes for the next era, it is imagined that design philosophy of "scaling-up" will be changed to one of "numbering-up" for the new series of micro-sized devices and reactors. Chemical processes will be operated increasingly on a local-level in a local environment such that material quantities can be produced as needed or on demand. Chemical education and the development of new career paths for chemical engineers is extremely important. The chemical engineer of tomorrow will require a new chemical engineering system that incorporates many different fields and new eco-disciplines to realize "Sustainability Engineering."
