Abstract
A system and process for separating organic material from solid waste such as material recovery facility (MRF) fines is disclosed. The fines are treated in a press, in which the fines are compressed against a wall having a set of holes. The fines are mixed with a substantial amount of water before being pressed. The water increases the amount of organic matter that is recovered from the fines. A wet fraction, extruded through the holes of the press, may be treated in an anaerobic digester.
Claims13
A process comprising steps of,
- mixing water with solid waste comprising fines producing a mixture having at least 50% water by mass per unit mass of the fines;
- and,
- pressing the resulting mixture at a pressure of at least 50 bar in an extrusion chamber.
A system for treating solid waste comprising fines, comprising:
- a mixer,
- a supply of water in communication with the mixer, and
- a high pressure extrusion press configured to exert a pressure of at least 50 bar on a mixture of the solid waste and the water from the mixer, the mixture having at least 50% water by mass per unit mass of solid wastc the fines,
- wherein the mixer is configured to mix water from the supply of water with the solid waste in an amount of at least 50% water by mass per unit mass of solid waste.
