A feed system for a reactor, a reactor assembly comprising such a feed system, and a method of supplying a feed material to a reactor with a feed system are provided. The reactor may be a pyrolysis reactor, such as a fluidised bed pyrolysis reactor. A method of pyrolysing a feed material is also provided. The feed system may comprise a feed conduit extending from an inlet to an outlet, and may have a first section including the inlet and a second section including the outlet. The first section may accommodate an auger. The second section may comprise at least one plug forming zone in which feed material is compressed into a substantially gas-tight plug during operation. There may be a temperature regulator for controlling the temperature in the second section. The temperature regulator may comprise a cooling jacket.

A synergetic system for waste treatment is provided. The synergetic system includes a waste treatment system configured to perform biological treatment of waste. Additionally, the synergetic system includes a gas purification system configured to purify exhaust gas generated during the biological treatment of the waste. The synergetic system further includes a feeding system configured to feed excess heat from the gas purification system back to the waste treatment system. The waste treatment system is further configured to use the fed back excess heat for the biological treatment of the waste.

A harvester high efficiency heat utilization device to be used in a harvester, includes: a drying chamber that dries grains of crops; a pipe that communicates with the drying chamber; a first heat exchanger provided in the pipe so as to communicate with an exhaust gas discharge port of an engine of the harvester; a combustion chamber that burns foliage of the crops; a second heat exchanger provided in the pipe so as to communicate with a high temperature gas discharge port of the combustion chamber; and a first blower that guides gas heat-exchanged by the first heat exchanger and the second heat exchanger to the drying chamber through the pipe.

A system for treating infectious waste is provided that employs a medical waste handling and shredding sub-system that feeds partially processed waste to an oxidizer to eliminate potential airborne infectious waste prior to transforming the medical waste into useful co-products. Medical waste is transformed into value added products including hydrocarbon based gases, hydrocarbon-based liquids, carbonized material, and recovered precious metals and rare earth materials in a system having as its transformative element an anerobic, negative pressure, or carbonization system. With medical waste as a feedstock for the production of valuable products, an economically viable and environmentally more responsible alternative to traditional methods of medical waste treatment is realized.

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 flare gas recovery system includes a primary gas sweetening unit; and a liquid-driven ejector in continuous fluid communication with the primary gas sweetening unit. The ejector includes an inlet configured to receive a motive fluid including a regenerable amine solvent in a rich state from the primary gas sweetening unit; a gas inlet configured to receive a suction fluid including a gas; and a fluid outlet configured to either directly or indirectly discharge to the primary gas sweetening unit a two-phase fluid including a mixture of the suction fluid and the amine solvent in a rich state.

An apparatus for the destruction of a precursor material includes a steam plasma reactor having a high temperature zone and a combustion zone. The high temperature zone is adapted for hydrolyzing the precursor material, whereas the combustion zone is adapted to effect medium temperature oxidation of the reactant stream where combustion oxygen or air is injected. A quenching unit is provided at an exit end of the reactor for quenching a resulting gas stream to avoid the formation of unwanted by-products.
