A system and method for converting food waste and other biologically-derived waste materials into nutrients for an algal growth system using worms to produce such nutrients is described. In one embodiment, a method for converting food waste into nutrients for an algal growth system using worms includes providing food waste to a container including a plurality of worms. The method also includes collecting castings from the food waste processed by the plurality of worms. The method further includes providing a wash to the container. The wash causes the castings to move to a bottom portion of the container adjacent to a moveable screen. The method includes actuating the moveable screen so that the castings pass through a plurality of holes in the moveable screen. The method also includes providing the passed castings to an algal growth system.

A method of manufacturing a fertilizer, including grinding solid vermicompost to create solid ground vermicompost powder, creating a liquid suspension agent, adding the solid ground vermicompost powder to the liquid suspension agent to create a liquified vermicompost solution, filtering the liquified vermicompost solution to create a concentrated liquified vermicompost mixture, and adding dispersant to the concentrated liquified vermicompost mixture.

The present disclosure provides a method of continuously converting kitchen waste using three environmental insects, including following steps: pre-solid-liquid separating and removing impurities of kitchen waste using feeding and drainage characteristics of Tenebrio molitor, Hermetia illucens, and Protaetia brevitarsis Lewis; feeding larvae of the Tenebrio molitor with solids added with crushed wheat bran in a day, and completely digesting the solids added with the crushed wheat bran in the day; and adding liquid with dung-sand of the Tenebrio molitor, crop straw dry powder, and probiotics to ferment, converting the fermented liquid added with the dung-sand of the Tenebrio molitor, the crop straw dry powder, and the probiotics by larvae of the Hermetia illucens, and then converting and digesting the fermented liquid added with the dung-sand of the Tenebrio molitor, the crop straw dry powder, and the probiotics by mixing larvae of the Protaetia brevitarsis Lewis.

A vermicomposting system for treating waste water streams that includes a pretreatment stage for converting liquid or semi-liquid organic waste streams into a feedstock for vermicomposting; a vermicomposting digestion stage having populations of worms and beneficial bacteria which consume and break down organic material and nutrients present in the feedstock from the pretreatment stage to create worm castings, vermicompost, and a liquid compost tea that contains plant nutrients, plant growth promoting substances, and beneficial bacteria; and a post-treatment stage in which the liquid compost tea is removed for use as an soil amendment or inoculant, or is further treated in a separate containment tank where nutrients and oxygen levels are controlled to increase specific bacterial and fungal populations.
