Includes not only gathering of solid wastes and
recyclable materials, but also the transport of
these materials, after collection.
Transfer and transport of wastes from the smaller
collection vehicle to the larger transport

long distances to a processing site and to prepare
materials for recovery of conversion products and
The final functional element in the solid waste
management system is disposal. Today the
disposal of wastes by land filling or land spreading
is the ultimate fate of all solid wastes.
