Abstract: Method and apparatus for processing green organic waste (hereafter “GOM”) into mulch particles for forming a mulch windrow including feeding means (11) for feeding GOM to a first cutting zone and rotating a plurality of blades (25) through that zone to cut the GOM into smaller particles, transferring the particles to a second cutting zone and rotating a plurality of blades (25) therethrough, to reduce their size to a suitable mulch particle size and ejecting the mulch particles at high velocity to form a windrow. The method and apparatus further includes the addition of moisture to increase the moisture content of the windrow formed.
