A method for treating solid organic material comprising the steps of
- providing phagotrophic algae,
- providing solid organic material,
- combining the algae and the solid organic material,
- allowing the algae to grow by engulfing or uptaking the solid organic material,
- forming an algal product, and
- collecting the algal product.
A method for treating solid organic materials comprising the steps of
- providing waste activated sludge at a pH of above 7,
- pretreating the waste activated sludge,
- adjusting the pH of the waste activated sludge to a pH of below 7,
- providing phagotrophic algae,
- combining the algae with the waste activated sludge,
- forming an algal product, and
- collecting the algal product.
A system for treating and disposing solid organic material comprising
- phagotrophic algae, solid organic material, a first vessel, a second vessel, and a third vessel,
- wherein the first vessel is a pretreatment vessel for performing a pretreatment step on the solid organic material,
- wherein the second vessel contains the algae and allows the algae to grow by engulfing or uptaking the solid organic material, thereby allowing the algae to produce one or more algal products,
- wherein the third vessel is a vessel for separating and collecting the one or more algal products.
