A brush for removing cremated remains from a crematory oven is entirely formed of metal to resist the high temperatures of the oven and has two linear brush assemblies fixed to a top frame. A steel handle extends rearwardly from the frame for grasping by a brush operator. One of the linear brush assemblies has smaller diameter crimped stainless steel bristles and is positioned at the front of the brush, the other of the linear brush assemblies has larger diameter crimped stainless steel bristles and is fixed to the top frame rearward of the front brush assembly. Side brush assemblies extend sidewardly and upwardly of the other two. In operation the brush is inserted at the front of the oven and drawn rearwardly after the cremation such that the rear bristles encounter and withdraw the larger elements of the remains, and the front bristles encounter and withdraw the smaller elements.

A system for digesting biodigestible feed that preferably includes the steps of comminuting the feed, introducing feed, an oxygen-containing gas, an accelerant, and bacteria into a digestion zone, the bacteria being suitable for digesting the feed under aerobic, anaerobic, and anoxic conditions. The contents of the digestion zone can be changed from aerobic operation to either anoxic or anaerobic operation, or vice versa, without changing the bacteria in the digestion zone.

A tissue digester system includes a container for housing a digestion chamber having an exterior vessel for holding digestor fluid and an interior vessel, the container extending from a first end to a second end, the interior vessel having perforations and having baffles extending from an interior surface of the interior vessel; a lid secured to the exterior vessel and to provide access to the digestion chamber; one or more heating elements positioned to apply heat to the digestion chamber; a motor engaged with the interior vessel and to create rotational movement of the interior vessel; a control system, having a temperature controller; and a movement controller; the control system is to rotate the interior vessel and heat the digestion chamber based on user commands; and the digestion chamber is to break down remains through application of the digestor fluid to the tissue remains.

A cremation accelerant module includes a carrier and flame accelerant material. The carrier comprises a combustible tube, such as, for example, one constructed primarily of paper. The flame accelerant material is disposed in solid form within the combustible tube. The flame accelerant material has a melting temperature, and a combustion temperature that is higher than the melting temperature. The combustible tube has a wall thickness selected to maintain sufficient structural integrity at the melting temperature to retard the flow of the flame accelerant materials in a molten state. The combustible tube has a wall thickness configured to degrade or burn sufficiently at the combustion temperature to allow the flame accelerant material to combust.

Agricultural incinerators are used to dispose of agricultural products, including, but not limited to, agricultural livestock carcasses. Incinerators are operated at extremely high temperatures (e.g., up to 3000-degrees F.) to dispose of an mitigate the spread of unwanted biologics, diseases, or other. The incinerator includes a double walled housing with a layer of sand that is used to protect the housing and to enhance the heat inside the housing. The sand provides a naturally low thermal conductivity to maintain the heat, which increases the efficiency of the incinerator. A hand crank opens a door into the incinerator to mitigate touching of any hot surfaces. In addition, a secondary burner can be used in the exhaust of the incinerator to reduce harmful emissions prior to exhausting into the ambient area of the incinerator.

A perfected cremation process includes the following operations: placing a mortuary coffin inside a crematorium oven configured to carry out the combustion of the mortuary coffin and cremation of the corpse contained in its inside; initiating the combustion of the mortuary coffin; conducting the combustion of the mortuary coffin for a time such as to achieve the degradation of the mortuary coffin, wherein it is provided arranging a combustion accelerant on the outer surface of the mortuary coffin, preferably on the outer surface of the cover of the mortuary coffin, before the initiation operation. This accelerant includes a compound selected from alkali metal salts, alkaline earth metal salts, ammonium salts, alkali metal peroxides or alkaline earth metal peroxides.

A mobile disaster crematory and method for cremating a body or other material are provided. The mobile disaster crematory comprises a housing, a front loading door in communication with an operator loading area, an exterior operator access door in communication with an equipment access room, and an exterior operator access control panel. An interior refractory lining defines a primary cremation chamber in fluid communication with a secondary environmental control chamber for oxidation of emissions to be conveyed from a crematory exhaust stack. An air intake system comprising valved air pipes delivers air into the chambers. Primary and secondary chamber burners are operably connected to temperature sensors, and to a valved fuel pipe and fuel supply, all operably connected to the exterior access control panel operably by a human operator. Power may be supplied by a local utility or a backup generator located in the crematory housing.

The present invention relates to a method for combustion of a biological material by means of microwave radiation, said method comprises providing said biological material to be combusted, wherein the biological material includes a human or animal body or body part, and optionally a container and an apparatus comprising a chamber and a source of microwave radiation; and directing microwave radiation at a power of at least 5 kW from said source of microwave radiation to said biological material to directly heat and combust said biological material in said chamber. The present invention further relates to a process for cremating a human or animal body or body part comprising said method.

A thermal processing apparatus (2) is furnished with a loading device, a cremation chamber (10), a heating device (14) for heating the cremation chamber (10), a fresh air supply device, an exhaust gas manifold (18a) for discharging the exhaust gas from the cremation chamber (10), a post-combustion chamber (28), and an exhaust air processing device (38). In order to provide a thermal processing apparatus with which a cremation process with minimal CO.sub.2 emissions can be carried out and an acceleration of the cremation process is achieved, it is proposed that the heating device (14) is designed to burn hydrogen.
