Hazardous Waste Disposal

Toxfree’s Hazardous Waste business is the leading provider of hazardous waste disposal in Australia. From our experienced and qualified staff, to an extensive range of treatment technologies and network of EPA licenced facilities, Toxfree prides itself on always finding a solution to clients’ hazardous and chemical waste needs. We also have the capacity to provide biomedical waste management as well.

Dry Cleaning Waste

Providing a better alternative to waste management for the dry cleaning Industry.

Toxfree’s C-Vap process has been specifically designed to deal with perchloroethylene (Perc) wastes. The process results in the recovery of this valuable solvent for reuse. The C-Vap process utilises a two stage separation system. The first separation stage involves solid liquid separation, allowing for the removal of solid and sludgy contaminants such as lint and dirt. The second stage involves purification of the resultant liquid to create a stable reusable product. The wastes generated from the purification process are of high calorific value and suitable for energy recovery.

Services:

• Collection, transport and recycling of Perc,
• Dangerous goods labelling,
• Assistance with regulatory compliance,
• Exchange pails,
• Separator water disposal, and
• Supply of “Recover” trademark for use.

Aerosol Recycling

Industrial aerosols typically contain flammable propellant gases and hazardous liquids and as such need to handled and disposed of with care.

In line with our waste hierarchy principles Toxfree have developed the capability to recycle aerosols through our proprietary T-Mark technology. This allows the liquid, gas and metals fractions to be separately collected and recycled.

Chemical immobilisation solidification

Toxfree specialises in the development of turn-key chemical and industrial waste treatment processes. Whether a customer has an existing treatment process that requires optimisation, or requires a tailored treatment program, Toxfree can provide a solution.
We have extensive experience developing and implement treatment programs to suit a diverse range of organisations including private businesses in agriculture and heavy industry as well as government and municipal organisations. Regardless of the scale or nature of your project, we can work with you to develop an effective, efficient bespoke solution that conforms to your needs.

Gas destruction

Chlorofluorocarbons (CFCs), which are used as refrigerants and halons, and used in fire extinguishers, are now known to be ozone depleting substances (ODS). These substances were in widespread use both in households and commercial premises for refrigeration, air conditioning, and in household, commercial and industrial fire-fighting applications. The modern Synthetic Greenhouse Gas (SGG) replacements for ODS have been found to have global warming characteristics.
The involvement of these substances in the partial destruction of the ozone layer came to the forefront of public awareness in the 1980’s. This culminated in the formation in 1987 of a treaty named The Montreal Protocol on Substances that Deplete the Ozone Layer. Most nations, including Australia, are signatories to this agreement and under its terms Australia has prohibited the venting of such substances to the atmosphere, along with a ban on further importation and production.

Base catalysed dechlorination

Base Catalysed Dechlorination (The BCD Process), is a chemical reaction process that can be used for de-halogenation of a range of chlorinated persistent organic pollutants (POPs).
The BCD process involves the addition of a caustic solution to the contaminated medium containing one or more halogenated or non-halogenated organic contaminant compounds. A proprietary catalyst compound is also required. The mixture is heated at a temperature suitable for the reaction to take place.
The BCD process is capable of treating high concentration POPs oils and even solids up to about 40% POPs content however BCD primarily utilise the process on lower concentration PCB contaminated oils. BCD use the process to reduce PCB concentrations in transformer oils from up to 10000 mg/kg to below detectable limits. The process must be monitored to ensure that the reaction continues to completion.
Given that the process is a batch operation, it is possible to allow the reaction to proceed until the required level of destruction has been confirmed; typically batches are treated to less than 2 ppm residual PCB concentration as per Australian requirements under the National PCB Management Plan 2003 and the relevant state Acts and Regulations.
