Cover Story: This century is characterized by a greater awareness of products of natural origin and respect for the environment. As a result, the research on natural compounds that are preventive towards the onset of some pathologies has grown enormously. In parallel, new strategies have been developed to recover natural bioactive compounds from industrial waste. The agricultural and forestry wastes are considered by-products with low economic value, generally used as feed for livestock or fuel for domestic heating. In this context, the wide range of natural compounds found in by-products recovered from sustainable sources, including pistachio shells, represents a challenging research topic with possible economic and environmental benefits, which might involve markets such as cosmetic, pharmaceutical, food supplements or additives.
