A recovery and reuse system for fatty oils from by-products and waste materials of vegetable fatty oil production

Abstract

Toei Chemical Co., Ltd. is one of the enterprises that systematically utilises by-products and industrial wastes. Only a few such enterprises are found in Japan. In our company, the crude fatty acids are recovered from the alkali foots (residual phospholipids) which are generated during the refining process for vegetable fats and oils. Moreover, the crude fatty acids are distilled for production of the soybean fatty acids, rapeseed fatty acids, and so forth. In the case of fractional distillation, simple fatty acids are produced. Also, our company has established a system for recovering vegetable fats and oils from the spent clay generated during the above-mentioned refining process. The system is so reliable that the quality of the vegetable fats and oils complies with JAS standards.
