1. A method comprising providing a solid waste treatment system, further comprising providing an autoclave having a steam outlet, a particulate filter, removing particulates suspended in steam discharged from the steam outlet of the autoclave following processing of solid waste, the method comprising the steps of:

  • discharging steam from the autoclave via the steam outlet;

    routing the discharged steam to an inlet of a separation vessel that further includes an outlet and a baffle between said inlet and said outlet, whereby the baffle is so configured so that steam is incident upon the baffle to reduce its flow velocity, and therein the particulate filter is provided after the outlet of the separation vessel to catch particulates in the steam exiting the separation vessel;

    charging the autoclave with steam routed from a steam storage system via the steam outlet and then the inlet of the separation vessel, thereby forcing particulates caught in the filter to be removed therefrom and to drop to a bottom of the separation vessel; and

    collecting particulates that drop from suspension in the steam and from said filter at the bottom of the separation vessel.
