The object of the present invention relates to a rotating drum for infeeding material by gravity to its interior, which can be used both inside a vessel that could be subjected to pressure or not, such as for example for the treatment of solid waste with water vapour, and externally for all types of equipment that require infeeding material to a rotating drum for the transportation and tumbling thereof, wherein due to the special configuration thereof it does not require an independent device for infeeding material to the rotating drum.

Disclosed herein is a receptacle configured to receive and contain waste, such as medical waste, during sterilization, wherein the receptacle is water permeable and heat resistant at a temperature of up to about 320° F. Also disclosed are systems and methods for sterilizing waste, such as with an autoclave, including the use of the receptacle.

A thermal decomposition apparatus comprises: a thermal decomposition apparatus mechanism being provided with a thermal decomposition furnace that decomposes a panel having a plastic layer; and a superheated steam generator that generates superheated steam being supplied to the thermal decomposition furnace. A furnace body of the thermal decomposition furnace is provided with an inner wall made of metal having a space for housing the panel, and with an outer wall made of metal enclosing the inner wall. A thermal insulation material layer is provided between the inner wall and the outer wall that encloses the inner wall. A heat storage material layer is provided between the inner wall and the thermal insulation material layer.

There are provided a method of producing reclaimed carbon fibers in which, even if a carbon fiber reinforced resin is not heated at 800° C. or higher, pieces of carbon fiber base material that are contained in the carbon fiber reinforced resin can be directly collected, and the variation in the resin residue content in the collected pieces of carbon fiber base material can be reduced, a device for producing reclaimed carbon fibers that can be used in the production method, and a method of producing a carbon fiber reinforced resin in which reclaimed carbon fibers can be effectively used. A method of producing reclaimed carbon fiber bundles which is a method of obtaining pieces of carbon fiber base material as reclaimed carbon fiber bundles from a carbon fiber reinforced resin (100) containing a plurality of sheet-like pieces of carbon fiber base material and a matrix resin, including heating the carbon fiber reinforced resin (100) and thermally decomposing the matrix resin to obtain a heat-treated product (102); and crushing the heat-treated product (102) and separating the plurality of pieces of carbon fiber base material into individual reclaimed carbon fiber bundles.

There is provided a method for efficiently taking out a metal part coated with a thermosetting resin from an electrical appliance which is no longer needed. Included are a step in which the electrical appliance is exposed to an atmosphere filled with superheated steam to carbonize the thermosetting resin, a step in which an impact is applied to the thermosetting resin which is made fragile by carbonization to cause destruction and a step in which the metal parts are separated from the destroyed thermosetting resin.

A waste treatment system comprises: a first hydrothermal treatment device for performing hydrothermal treatment of waste; a first solid-liquid separation device for separating a first reactant of the first hydrothermal treatment device into a solid and a liquid or slurry; a second hydrothermal treatment device for performing hydrothermal treatment of the solid of the first reactant; a second solid-liquid separation device for separating a second reactant of the second hydrothermal treatment device into a solid and a liquid or slurry; and a fermentation device for fermenting the liquid or the slurry of the first reactant and the liquid or the slurry of the second reactant.

There is provided a carbonization/oil recovery processing furnace which can be manufactured at a relatively low cost and has less deterioration due to corrosion in association with operation, and can also be maintained and managed at low cost. The carbonization/oil recovery processing furnace is constituted so as to process discarded materials including plastic waste by carbonization and oil recovery with the use of superheated steam which is supplied from the outside, and the carbonization/oil recovery processing furnace is constituted of iron-made external structures and stainless steel-made internal structures which can be separated from the external structures.

Some embodiments are directed to a process for forming products from animal waste (e.g., poultry litter). The products may include a controlled release fertilizer and renewable natural gas. The process may include providing a feedstock comprising greater than about 80 percent poultry waste and a moisture content of about 25 percent. The feedstock may be diluted to form a slurry having a moisture content of about 90%. The slurry may be mechanically refined to reduce the particle size distribution and the average particle size of the slurry. The slurry may be anaerobically digested to produce biogas and a digestate. The biogas may be converted to renewable natural gas, and the digestate may be converted to a controlled release fertilizer. Additionally, some embodiments are directed to methods of reducing nitrogen emission from soil amendments. Some embodiments are directed to reducing nitrogen emissions sufficient to produce emissions offset credits.
