Abstract
The present disclosure provides methods for hydrothermally treating sewage wastes to preferably obtain valuable products, including fatty acids, carbon-neutral combustible hydrochar fuels, heavy metal salts for recycling into industrially important metals, and phosphoric acid and derivatives thereof. Fatty acids can be chemically transformed into useful products such as soaps, cosmetics and liquid transportation fuels such as biodiesel and conventional gasoline, diesel and aviation fuels; hydrochars created in the process can be combusted and the energy created used to generate electricity; heavy metal salts can be chemically reduced to form industrially important metals for use as catalysts; and phosphoric acid and its derivatives have very important roles as fertilizers in agriculture.
