A method of processing MSW, either sorted or unsorted, which can be carried out through the use of canisters to hold the waste feedstock, and autoclaves specially designed to process the waste at suitable temperature and pressure combinations is disclosed. The final solid product is a mixture of carbon ash and non-combustible materials, such as, metals, drywall, etc., and syngas that has an enhanced BTU value, typically between about 300 to 700 BTU/ft.sup.3. The remainder solid material generally amounts to approximately 5% of the original MSW volume. This material can then be sorted for metals with the balance being sent to a landfill or other recycling processes depending on its composition.

Disposal of refuse

Existing approaches to refuse handling are all based on historical approaches which rely on a network of refuse collection vehicles collecting waste from individual households and delivering this to a centralised landfill or MBI location. This is highly undesirable and wasteful. An alternative process is disclosed, relying on the thermal treatment of waste and like products produced or brought in to the residential property and processed within the domestic curtilage to produce fuel or other forms of energy. Thus, domestic waste will be thermally treated at the home instead of being collected by local authorities and disposed of. The waste input put material will be loaded into a domestically engineered thermal conversion unit either directly or after a pre-process such as shredding. The feedstock will be converted into fuels by a thermal treatment, such as pyrolysis. The resultant output of oil and gas can either be stored or fed into a boiler unit to be used as a fuel to produce hot water, or used to run an electricity generating unit to power the dwelling in question or for supply to a feed-in tariff. Thus, a domestic dwelling includes a thermal treatment unit for processing waste produced in the dwelling, an output of the thermal treatment unit being combusted for producing an energy output for the dwelling. A suitable pyrolysis chamber is disclosed.

Methods of producing a gas from a combustible material

Disclosed are methods and systems for producing a gas from a combustible material. In particular, disclosed are methods and systems for batch-type production of a gas from a combustible material. The methods and systems include igniting at least a portion of the combustible material loaded in the sealed containment structure to form a thermally affected layer, wherein the step of feeding the oxidant into the sealed containment structure is carried out so that conversion of the combustible material to a gas at one point in the sequence is initiated prior to complete conversion of the combustible material at a previous point in the sequence.

Method and plant for waste treatment

The present invention relates to a method and a plant for treating carbon-containing waste that may comprise mineral fillers and/or potential contaminants. This method comprises: preparing a molten glass bath at a temperature between 1100° C. and 1600° C.; loading the waste to be treated into said molten glass bath; injecting an oxidizer and optionally a fuel under pressure into said molten glass bath by means of at least one hose, one end of which is immersed in said bath, said oxidizer being introduced in a molar amount less than the molar amount of the carbon-containing compounds, thus causing combustion of said waste and generation of hot synthesis gases; implementing heat exchange between a heat-transfer fluid and the hot synthesis gases in conditions allowing simultaneous recovery of at least part of their heat energy and at least part of the heat energy released by their combustion, air being injected sequentially into said gases during said heat exchange to cause self-ignition of the mixture of said gases and air, each injection increasing the degree of combustion.
