A method of producing mineral-rich algae by growing algae with an algae biofilm growing apparatus, wherein the algae is fed a mineral-rich feed stock. Furthermore, the mineral-rich algae is harvested and used as a foodstuff for human and animal consumption.

The present invention relates to a method for treating wastewater. The method includes treating an influent flow of raw wastewater from one or more sources in a harvestable algae biofilm treatment system. The treated wastewater is then delivered to one or more wastewater treatment lagoons or a mechanized biological treatment system for additional treatment. Also disclosed is a system for treating wastewater.

A system and method for vertically-oriented, modular, automated, emissions-controlled composting. In an embodiment, the system and method involve construction of a vertically-oriented set of composting modules comprising a receiving and offloading level, one or more composting bay levels, a feedstock staging level, a biofilter level, a vertical conveyor for uploading feedstock to the feedstock staging level, a freight and personnel elevator, and a leachate tank. This composting system and method reduces the land area required for composting, increases the capture of emissions from composting, and reduces the labor-intensive and heavy-equipment-intensive nature of current methods.

The invention relates to a method for producing microalgae on a support (14) that is movably mounted essentially in an aqueous medium contained in a tank (12), said method comprising a succession of phases in which the microalgae developing on the support (14) are exposed to sunlight and phases in the shade, the light intensity received in the shade being less than 50% of the average light intensity received during the sunlight exposure phases. The total length of the shade phases is more than 50% longer than the total length of the sunlight exposure phases.

Disclosed are methods and devices suitable for growing algae.

Production equipment for production of biological material, comprising a bioreactor 12, 3 for the cultivation and production of unicellular microorganisms and communities of microorganisms as well as multicellular aquatic plant and animal organisms. The bioreactor has at least one space for the proliferation 21 of unicellular microorganisms, communities of microorganisms, multicellular aquatic plants and animals, which space is in communication with a device 23 for cultivating, transporting and harvesting said microorganisms or aquatic organisms, comprising a pipe chain conveyor.

An apparatus (10) for the pressurized recirculation of organic material comprising a reactor vessel (12) capable of being pressurized and in which both anaerobic digestion and aerobic composting of organic material may occur, the reactor vessel (12) having both an inlet (14) and an outlet (16) for organic material, together with a conveyor means (18, 20, 22, 28, 29, 30, 32, 34 and 36) to convey organic material to the inlet (14) and from the outlet (16), whereby organic material may be transferred between the outlet (16) and the inlet (14) to achieve recirculation and rearrangement thereof while maintaining a pressurized state. A method for the pressurized recirculation of organic material is also described.

A system and method for vertically-oriented, modular, automated, emissions-controlled composting. In an embodiment, the system and method involve construction of a vertically-oriented set of composting modules comprising a receiving and offloading level, one or more composting bay levels, a feedstock staging level, a biofilter level, a vertical conveyor for uploading feedstock to the feedstock staging level, a freight and personnel elevator, and a leachate tank. This composting system and method reduces the land area required for composting, increases the capture of emissions from composting, and reduces the labor-intensive and heavy-equipment-intensive nature of current methods.

A composting bin and method for a vertically-oriented, modular, automated, emissions-controlled composting. In an embodiment, the system and method involve construction of a vertically-oriented set of composting modules comprising a receiving and offloading level, one or more composting bay levels, a feedstock staging level, a biofilter level, a vertical conveyor for uploading feedstock to the feedstock staging level, a freight and personnel elevator, and a leachate tank. This composting system and method reduces the land area required for composting, increases the capture of emissions from composting, and reduces the labor-intensive and heavy-equipment-intensive nature of current methods.
