A system and method for vertically-oriented, modular, automated, emissions-controlled composting. In a preferred 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.

Culture systems and methods of using same. The systems include a housing defining an inner space. The inner space includes a headspace and at least a portion of a reservoir. A surface for immobilizing cells is moveable between the headspace and the reservoir.

Embodiments of the present invention may provide fluid flow coordinators, passive flow field modifiers, or even inwardly protruding helical spines which can be used in continuous, scalable, low energy usage, bioreactor systems perhaps to provide optimal mixing of microorganisms with nutrients, gases, or the like or even to move microorganisms, such as algae, in and out of light for effective and optimal growth.

An assemblage appliance and method of recycling organic waste into biogas and liquid fertilizer, implementing essentially anaerobic digestion processes, is described. The assemblage appliance includes: a pliant structured exoskeletal envelope, pliable collapsible anaerobic digester and gas tank. A compact kit-of-parts for assembling the aforementioned appliance and respective method using the aforementioned appliance for recycling organic waste into biogas and liquid fertilizer are described.

Processes, systems, and associated control methodologies are disclosed that control the flow of biogas during the biogas cleanup process to create a more consistent flow of biogas through the digester, while also optimizing the output and efficiency of the overall renewable natural gas facility. In representative embodiments, a biogas buffer storage system may be used during the cleanup process to control the pressure and flow rate of biogas. The biogas buffer storage system may monitor and control the biogas flow rate to either bring down or increase the digester pressure, thereby maintaining a normalized biogas flow rate.

Disclosed herein are carbon dioxide capture devices, facilities, methods, and compositions. Specifically disclosed herein are devices, facilities, compositions and methods to capture carbon dioxide from the Earth's atmospheric air for providing long-term sequestration of the captured carbon and/or utilization thereof.
