The invention provides a system for pyrolysis, comprising: (i) a gas producer comprising a gasification zone and a producer gas outlet, wherein the gas producer is configured to: oxidise at least one carbon-containing feed in the presence of an oxidising gas in the gasification zone to form a producer gas; and discharge the producer gas from the gasification zone via the producer gas outlet, wherein a residual oxygen content of the producer gas is substantially depleted or maintained below a maximum predetermined amount by controlling a ratio of oxygen fed to the gasification zone to the carbon-containing feed, (ii) a pyrolyzer comprising a pyrolysis zone and one or more pyrolyzer gas outlets, wherein the pyrolyzer is configured to: feed the producer gas discharged from the gasification zone to the pyrolysis zone; pyrolyze a pyrolyzable organic feed in the pyrolysis zone in the presence of the producer gas to produce a carbonaceous pyrolysis product and a gas mixture comprising combustible components comprising pyrolysis gas; and discharge the gas mixture from the pyrolysis zone via the one or more pyrolyzer gas outlets, and (iii) a first combustor comprising a combustion zone, wherein the first combustor is configured to: receive the gas mixture discharged from the pyrolysis zone in the combustion zone; feed an oxygen-containing gas to the combustion zone; and combust at least a portion of the combustible components present in the gas mixture in the combustion zone to produce a combustion product gas.

A municipal solid waste recycling facility for producing a solid recovered fuel is provided. The municipal solid waste recycling facility includes a pre-shredding unit and a shredding unit. The pre-shredding unit includes a trommel configured to sort a first stream of solid waste by size into a second stream of solid waste and a third stream of solid waste. The shredding unit includes a primary shredder configured to shred the second stream of solid waste.

A method for processing material that contains biomass. The material is led onto a conveyor. The conveyor conveys the material to an apparatus for mechanical processing and/or to a further processing plant. The moisture content is measured and/or the size of pieces of non-combustible material and/or the content of non-combustible material in the material flow is measured in connection with the conveyor. Based on at least one of the measurements, material is conveyed to the material to be conveyed for further processing and/or to the apparatus for mechanical processing, or to at least one material to be conveyed elsewhere than to the further processing plant or the apparatus for mechanical processing. Also a system for processing material that contains biomass.
