Because of urgent demand for increase of food production and change for dietary pattern in developing countries, the development of potato industry has become the first among all food crops in developing and developed countries. Thus starch extraction industry plays a significant part in changing potato from a vegetable into a member of main food crops including rice, wheat and maize. While large amount of waste residue has been generated in potato starch processing, which contains various of organic materials such as protein, carbohydrate, starch et al., and brings waste of raw materials and a negative result to the environment if this waste residue is stacked outside without any disposal. This review focus on analysis and comparing of efficiency, technical requirements, economic and environmental effect of current recycle technologies for waste residue in potato processing, including bio-gas production, protein feed production and extraction of pectin and dietary fiber. Which shows that bio-gas production may have the most brilliant prospect in this field. Further research may be established in industrialization of this bio-gas producing technology, which may also contribute to future mixed culture fermentation technology, an effective way for growing energy crisis. While the other and most ideal solution lies in cleaner production: fully using of potato in food production and no waste residue will be generated.
