Cold Thermal Oxidation


Cold Thermal Oxidation (CTO) is a recent addition to treatment methods for solid waste. Combining lime with patented reagents will generate temperatures approaching 500° C in a non-pyrolitic process that produces a fine, granular calcinate residue suitable for recycling.

CTO is a process that:

Does not generate either combustion dispersed air emissions nor release leachate while dust particles are removed.

As a closed loop process, no wastes or exhausts are generated and the water employed is reused. Dust particles are removed from the air.

Social and environmental impacts are eliminated from the waste disposal into a public or private land fill in contrast with “termovalorizers” and incinerators.

Can take place within a confined space.

CTO can handle a variety of wastes including:

1) Municipal solid waste, differentiated, non-differentiated damp waste and vegetable matter.

2) Sludge generated by civil and industrial water treatment plants

3) Industrial waste including hydrocarbon compounds, even ‘asphaltic’ and organic matrices, solid, semi-solid, pasty and or sludge.

4) Soil and other matter contaminated by organic hydrocarbon matrices.

CTO resolves problems associated with solid waste disposal, using sterilization, desiccation, oxidation and fixation to produce an inert residue. It is not to be confused with traditional use of quick lime although CaO is a treatment ingredient and is therefore classified as a current treatment technique.

Post treatment wastes will be dry and recoverable for recycling. It will consist of an inert residue which is dry, sandy, calcinate material with very low permeability, hydrophobic, compressible, oleophilic, insulating, basic with a s.g. of +/- 1. This residue content is within limits for most uses with regard to residue and leachate content.
