Abstract
A theoretical explanation and the experimental results of the volume reduction ratio in incineration and compression are presented for low level solid waste treatments.
The volume reduction ratio of the combustibles by incineration can be expressed as the product of the weight reduction ratio and the reverse ratio of bulk densities before and after treatment. The weight reduction ratio is the most important factor in the process.
The volume reduction ratio by compression is represented only by the reverse ratio of the two bulk densities, because the weight reduction is not involved. The bulk density of a compressed waste decreases due to its elasticity when the mechanical compression is removed. The preventive measures against volume restoration should be taken to retain the effect of volume reduction.
