2. WHAT DO YOU MEAN BY SOLID
WASTE PROCESSING ?
Solid waste processing is an operation
that changes the chemical, physical, or
biological properties of solid waste to
make it easier to dispose of, recover a
resource, or transfer solid waste material,
excluding the transportation of solid
waste.
Introduction
3. PURPOSE OF PROCESSING
SOLID WASTE
The processing of wastes helps in
achieving the best possible benefit
from every functional element of the
solid waste management (SWM)
system.
4. TECHNIQUES OF PROCESSING SOLID WASTE
• SIZE REDUCTION.
• VOLUME REDUCTION.
• AIR SEPARATION.
• MAGNETIC
SEPARATION.
• SCREENING.
5. SIZE REDUCTION
•Size reduction refers to the conversion of waste into smaller portion
•This helps to obtain the final product in reasonably uniform and
considerably reduced size compared to original form.
•It is essential in recovering material for reuse and conversion to energy.
•Size reduction techniques are used either to facilitate economic packaging
for transportation or to prepare solid waste for subsequent treatment.
6. •Magnetic separation of municipal solid waste (MSW) is perhaps the
simplest of unit processes for recovering materials .
•The process is used in industries such as mineral beneficiation of iron ores
, the scrap industry use it to produce clean iron an d steel metal scrap etc.
