An eco‐friendly product has been the primary agenda of twenty‐first century of the global scientists. One of the main focuses is by‐product recycling of food processing industries. It has been long time since food industry byproduct converted into energy and value added products. Potato processing is newly emerging food processing factories in developing countries, and potato is the fourth important crop globally. A dramatic food demand increment had shown in the past two decades. This leads to increase the number of food processing industries. Nowadays, food processing industries particularly processed potato manufactures are expanding and generate a huge volume of potato peel. This by‐product causes environmental pollution due to decomposition. However, food byproducts like potato peel have essential organic matter. So this review introduces the potential use of potato peel as food preservative, pharmaceutical ingredient, renewable energy, and animal feed to promote eco‐friendly food industries.

Potato is the fourth main stable crop next to rice, wheat, and maize consumed widely all over the world. Nowadays, types of processed potato products have increased from time to time to meet the tremendous interest of consumers. Food processing factories produce many volumes of wastes as a byproduct (Charmley, Nelson, & Zvomuya, 2006; Schieber & Aranda, 2009). Peels of vegetables are the main byproduct of plant processing factories which has important organic compounds. Potato waste contains valuable chemical components like phenols which are suitable to apply in food preservation and pharmaceutical industries (Grunert, 2018;
