Autoclave

Compliant, state-of-the-art technology for treating regulated healthcare waste.

The alternative to just incineration

Autoclaving is the process of pressure steam sterilisation that kills 99.9% of pathogens. Sizes range from small units used to sterilise medical tools and equipment in general practices, dental clinics and other medical facilities, to large machinery that can process over 1,000 kg of waste per hour.

The autoclaving process alone can achieve a volume reduction of 45%. When combined with compaction, it can achieve up to 60% total volume reduction.

Our autoclaves are built to meet stringent safety requirements and comply to Australian Standards for pressure vessels. All autoclaves are registered and monitored by state government bodies as per statutory requirements.

Autoclave in action

The collectors are scanned and weighed to ensure origin traceability before being loaded into the waste carts. These waste carts are then rolled into the loading chamber before being sealed.

Outside air is removed and filtered to minimise any possible pathogen release, before the autoclave vessel is pressurised to 25 kg. High pressured steam is then released rapidly into the chamber, increasing the temperature to approximately 140-150°C. This achieves a 4log kill of microorganisms.

Each cycle takes around 75 minutes to complete and can treat over 1,000 kg of waste per hour. At this point, the process variables and other related information are stored into a hard drive for record keeping purposes.

By the end of the cycle, the waste volume has been reduced (or melted) to less than 50% of its original volume. The carts are then emptied automatically into a compactor before it is sent to landfill.

Applications

Autoclaves are the proven alternate technology for the treatment of clinical waste. This technology generates less air pollutants than most other high-heat thermal process.

Preventing environmental contamination

Autoclaves are the greener and safer alternative to just incineration. It prevents environment contamination by harmful pollutants such as dioxins, furans, metals and acidic gases which would normally be emitted by an unfiltered incinerator.

The Western Australia Department of Health lists autoclave as the first treatment option for clinical and sharps waste (Operational Directive 0258/09 section 3.3).
