<p>A recirculating composting apparatus cycles air and waste gases through a composting vessel, into a curing bin which contains previously composted material. Within the curing bin, ammonia and other noxious gases are adsorbed and converted into valuable fertilizer. The gases released from the curing bin may pass into another curing bin and then be recirculated back into the composting vessel, or may alternatively be released into the environment or passed through a biofilter. In preferred embodiment, like containers may be used for each curing phase and also the composting phase. The use of similar or compatible containers allows an entire vessel to be converted from a composting vessel into a curing bin simply by disconnection at one location and reconnection at a different location, without having to disturb the contents within the vessel or incur the undesired associated labor. Furthermore, resulting fertilizer products may be enriched with nutrients, have pH controlled, or be controlled to optimize various elements, gases, or heat during the curing phase, thereby simultaneously preventing a loss of nutrients and simultaneously increasing the economic value of the finished fertilizer.</p> |
