| titleOfInvention | Organic plant growth medium based on sawmill waste |
| abstract | Disclosed herein is an organic potting mix which is produced from sawmill wastes comprising predominantly wastes from the pinus genus either alone or mixed with other organic waste materials by a continuous process, wherein the sawmill waste feedstock is comminuted, submerged in heated water containing treatment chemicals and then at least partially dewatered to a moisture content of from 15% - 25% ww and a moisture capacity of about 50% ww. Particularly disclosed is a method for production of organic plant growth media from sawmill waste, said process comprising the steps of:- introducing comminuted sawmill waste into an inlet of a conveyor mechanism containing a body of heated water including a chemical treatment composition selected from a pH modifier, plant nutrients, pesticides, herbicides, microbicides, parasiticides, fungicides or any combination thereof; submerging saidsawmill waste in said body of heated water for a predetermined period of time to kill microorganisms, insects, plant and animal parasites and the like whilst transporting treated sawmill waste towards an outlet of said conveyor mechanism; and at least partially dewatering said treated sawmill waste to a predetermined moisture content. The potting mix so produced may be subjected to further comminution in an apparatus which applies mechanical shear under pressure to produce a peat moss alternative having an enhanced moisture capacity up to about 80% ww. An apparatus for the continuous production of the potting mix comprises a screw auger located in an inclined tubular body, wherein the sawmill waste feedstock is submerged during travel from a lower end to an elevated dewatering end of said tubular body is also disclosed. |
