    Sustainable Production can be defined asthe creation of goods and servicesusing processes and systems that are:Non-polluting; Conserving of energy

    and natural resources; Economicallyviable; Safe and healthful for workers,communities, and consumers; Sociallyand creatively rewarding for all workingpeople.
