Chemical Free Cleaning with Sodexo
In June 2019, DeGrussa’s hospitality and catering contractor Sodexo conducted a chemical free cleaning trial. Sodexo was looking for opportunities to minimise the environmental impact of cleaning and reduce safety hazards to staff. Sandfire was pleased to host the trial, hoping to implement the system across the site pending trial results.
Cleaning chemicals cause a range of harmful impacts and hazards to people and the environment. At DeGrussa, chemicals used for cleaning can impact the efficiency and operation of the waste water treatment plant by killing bacteria that are essential for breaking down and processing organic matter. Staff exposure to these chemicals creates health risks including potential breathing problems, eye irritation and skin rashes. Risks are currently mitigated through the use of personal protective equipment (PPE).
During the trial, Sodexo used an alternative cleaning technology, the Tersano lotus® PRO to clean the floors in the dining room. The lotus® PRO works by creating Stabilised Aqueous Ozone (SOA) – a cleaning solution that uses only cold water and oxygen. No chemicals from start to finish. To date, the trial has showed encouraging results with no difference to the quality of hygiene.
Over a six month period, it is estimated that the site uses 416 litres of standard floor cleaning chemicals. This represents a significant opportunity to cut down on hazardous chemicals, reduce our environmental impact and risk to workers. Using the new technology, staff will require less PPE, which will also reduce plastic waste to landfill.
