Advantages of gutter oil soap

Gutter oil soap advantages:

1, gutter oil can be used to make soap and biodiesel after processing, can realize the rational use of food waste.

2, grease hydrolysis products in carboxylic acid is an electrolyte, glycerol is a non-electrolyte, sucrose, starch hydrolysis products are non-electrolytes.

Commonly used refining process includes degumming, alkali refining (deacidification) decolorization. Degumming is to remove the phospholipids and other gums in the oil and grease, there is water to hydrate the phospholipids and other gums, and then precipitate precipitation of the hydration method; and the use of concentrated sulfuric acid to make the phospholipids and similar impurities carbonization, precipitation of the acid refining method. The main role of alkali refining is to remove the free fatty acids in the oil, but due to the generation of flocculent soap, adsorption and removal of pigments and impurities in the oil.

Gutter oil has a new value:

On March 09, 2012, the Embassy of Japan in China and the Beijing Huanyou Science and Technology Research Center **** with the launch of the "Project Luminous gratuitous assistance" project. The Japanese government provides technology, equipment, and funds to help recycle waste cooking oil for soap projects.

Beijing Environmental Friendship Science and Technology Research Center to the Japanese Embassy to apply for the "waste cooking oil to make soap" project, has been approved by the Ministry of Foreign Affairs in Tokyo. In the future, it will be possible to reuse waste cooking oil to make soap in China. Li Li, director of the Research Center of Eco-friendly Technology, introduced the division of labor between Chinese and Japanese experts.

Li Li said it will take a year to study the project, and there is no specific timetable for when the soap made from cooking oil can be seen in Chinese supermarkets.
