7.3.13 Solid Waste Treatment Through Incineration
Combustible wastes will be segregated at source and can be sent in batches to an off-site
provider for incineration. Incineration reduces the volume of waste requiring disposal and
removes the organic content of the waste [Ref.44]. The resulting product primarily consists of
dry inorganic materials (e.g. slag, ashes, solidified scrubber solutions) that can be safely stored,
if required and disposed. Typically, incineration can result in a volume reduction factor of
between 25 to 100.
Application
· Combustible wastes.
Design Data
· Volume reduction factor between 25 and 100.
Advantages
· Destroys hazardous organic compounds and flammable solvents;
· High volume reduction factors;
· Generates a stable inert ash.
Disadvantages
· Off-gas treatment generates secondary wastes.
7.3.14 Solid Waste Super Compaction
A super compactor can be used to compact specially designed compactable drums. This will
result in a waste stream that is significantly reduced in volume and virtually void free.
The compaction factor is determined by the material composition and overall mix of materials.
Typical compaction factors range from 3 to 8 with an average of approximately 5 [Ref.35].
The resulting pucks are sorted in accordance with their height. The pucks are individually
selected and transferred to the final drum storage to maximise the packing density.
Advantages
· High volume reduction factors;
· Voidage elimination.
