Waste processing allows offloading the lands allotted
for waste dumping sites and reducing the environmental
pollution. A best possible use should be made
of waste materials in production processes so that they
could be brought back into natural cycles of matter.
Those views, expressed as early as by V.I. Vernadskii
in his time, should underlay the approach to solving
industrial and domestic waste problem, which relies on
their use rather than disposal.
