The word sustainability, like “green,” “natural” and “eco-friendly,” covers a lot of ground. It may mean a product contains organic ingredients, has biodegradable packaging or saves energy in some way. It may also mean that a manufacturer donates a portion of its proceeds to a charitable cause, organization or community, or something else altogether. One thing’s for sure: Consumers want more foods that fall within the sustainability spectrum, and manufacturers are wise to consider moving to greener products to meet this demand.
