The present invention is a composting bioreactor system that continually receives biodegradable solid wastes, waste waters and exhaust gases, automatically recycles the biodegradable wastes into nutrients and heat energy, and automatically supplies the nutrients and heat into an integrated hydroponic or aquaponic system. This invention together with integrated food growing system may be installed onsite such as balconies, backyards and premises of restaurants and food factories etc. therefore may lead to zero mileage targets both for recycling wastes and for supplying foods. This invention integrates composting process and aquaponic technology together and may establish a closed-loop recirculation of both water and gases therefore upgrades aquaponics into compoponics. A compoponic system has both soil and soilless growing beds and mimics nature recirculating nutrients, carbon and energy among human being, animals, microorganisms and plants by way of photosynthesis, slow burning by cellular respiration and burning by combustion.

A bioreactor (1, 2, 3) and its use for the conversion of organic residual and/or waste materials into an organic nutrient solution with a proportion of at least 10% plant-accessible mineralised nitrogen relative to the total nitrogen content of the nutrient solution, with a reaction tank (5), where the reaction tank (5) has an input feed (6) through which suspension (4) can be introduced into the reaction tank (5), and where the reaction tank (5) has an outlet feed (7), through which the suspension (4) can be discharged from the reaction tank (5), where the carrier element (10) has at least one inner and one outer settlement surface (11), on which ammonifying and/or nitrifying bacteria can collect.

An assemblable appliance and method of recycling organic waste into biogas and liquid fertilizer, implementing essentially anaerobic digestion processes, is described. The assemblable 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.

An apparatus for recovering nutrients or water from digestate comprises one or more solid-liquid separation units, an ammonia stripping device, and a gas scrubbing unit. In a process, digestate is separated into a solids portion and a liquid portion. Ammonia is stripped from the liquid portion and converted into an ammonium salt solution which may be sold or used as, or blended with, a fertilizer product. Optionally, at least part of the remaining liquid portion may be concentrated to produce brine. The brine is mixed with the solids portion. The mixture may be dried and used as, or blended with, a fertilizer product. Optionally, a least part of the remaining liquid portion may be re-used as dilution water in a digester. A solids portion of the digestate, and one or both of an ammonium salt solution and a brine, may be used as fertilizer without thermal drying.

A digester system comprising a primary digester tank containing a primary feed material portion, a secondary digester tank containing a secondary feed material portion, a first conduit connected between the primary digester tank and the secondary digester tank to define a primary tank lower opening within the primary digester tank and a secondary digester tank lower opening within the secondary digester tank, and a flow control valve configured to allow or prevent flow of fluid through the first conduit. When the flow control valve is configured to allow flow of fluid through the first conduit, a portion of the primary feed material portion flows from the primary digester tank to the secondary digester tank to form the secondary feed material portion.
