The compost is filled into trays with the help of specially designed material handling equipment and stacked into pasteurization chambers where the final stage of composting takes place. An even more controlled environment is created. During the six days of this phase, the compost must
be maintained within a very close temperature range to insure adequate growth of the beneficial organisms and eradication of any antagonistic organisms. Steam assists the naturally occurring heat of the compost to reach temperatures that selectively kill most all of the harmful organisms. A successful pasteurization completes the composting process.
