Processing method of changing food waste into resources

Abstract

The invention relates to a processing method of changing food waste into resources. Ethanol, methane, liquid fertilizers, solid fertilizers, pet food and the like can be obtained through the following steps of food waste solid and liquid separation and respectively treatment after the food, the potato type, the vegetable melon and fruit type, the animal meal and fish bone type and rubbish sundries are sorted from the solid, and oil for producing biodiesel, soap and glycerin, purified water used for fish culture, water plant planting and farmland and garden irrigation and the like can be obtained after liquid treatment. The methane is used for combustion after being dewatered, and is used for electric power generation after being desulfurized, and the waste heat of the electric power generation is reused. The method of the invention fully utilizes waste materials, produces various products, and has the advantages of low energy consumption and high yield.

AI Technical Summary

Benefits of technology

This patented describes different ways to use bioethane produced by burning corn crop residue after extracting alcohol content into fuel that could help save fossil fuels during times when traditional sources are being exhausted. Additionally, it suggests creating an organic fertile soil through digestive processes where crops have been left behind instead of returning them back to their original state. Finally, there has also developed methods to recover valuable metabolites like glycerine with potential uses such as producing clean water without polluting our environment.

Problems solved by technology

This patented describes how restaurants generate large amounts of wastes - including disposable plastics such as cups or utensils made from paperboard material used for storing meals in their homes. These wereted items can be expensive because they cannot be reused again due to environmental concerns associated with them. To solve this problem, these companies have developed various ways to process cookery residue (often called 'spatters') back into usability by producing biofuels like ethanol through anaerobic decomposition processes. However, current techniques require significant resources during processing, making it difficult to reuse spilled bits effectively without causing pollution issues.
