Patent number: 9925491Abstract: Waste treatment comprises heating it in a chamber to effect pyrolysis of the waste, introducing oxygen into the chamber to effect combustion of the pyrolyzed waste, and contacting off-gas from the pyrolysis and/or combustion steps with an oxidation catalyst to convert carbon monoxide and hydrocarbons in the off-gas into carbon dioxide and water and with a reduction catalyst to convert nitrous oxides to nitrogen and oxygen. Thus, domestic waste is treated in a batch process using catalytic converters to reduce the level of toxic components before off-gas reaches the atmosphere.Type: GrantFiled: March 6, 2017Date of Patent: March 27, 2018Assignee: Pyropure LimitedInventors: Howard Morgan Clarke, Peter Bartl

Publication number: 20180073735Abstract: In apparatus and method for waste treatment by pyrolysis, treated waste is flushed through a grid (18) to trap recyclable material in the pyrolysis chamber (24). Pyrolysis is carried out at a temperature of from 400-700° C. and off gases are dissolved in a solution in scrubber (13) for disposal in a water course. Water is introduced into the chamber as superheated steam via pipes (5) so as both to flush away treated material and clean the chamber. Recyclable waste is separated from non-recyclable by treating non-recyclable waste by pyrolysis, and flushing treated non-recyclable waste away through liquid exhaust (8). Apparatus is made as a modular, free-standing unit and comprises plugs for connection to an electricity supply, to a water supply, and to a sewage system (16) and has a chamber with a volume in the range 0.01-0.5 m3.Type: ApplicationFiled: November 20, 2017Publication date: March 15, 2018Applicant: Pyropure LimitedInventors: Howard Morgan Clarke, Michael Benjamin Elder
