Green engineering
Green engineering approaches the design of products and processes by applying financially and technologically feasible processes and products in a manner that simultaneously decreases the amount of pollution that is generated by a source, minimizes exposures to potential hazards (including reducing toxicity and improved uses of matter and energy throughout the life cycle of the product and processes) as well as protecting human health without relinquishing the economic efficiency and viability. As such, green engineering is not actually an engineering discipline in itself, but an overarching engineering framework for all design disciplines.
