Presco technician, Chad, disposing of waste water at a naturally filtering catchment pond.
Most of our cleaning processes create waste. For example, to clean an area that is particularly soiled we put a lot of cleaning chemical down and then wash it off. That dirty, chemically water needs to be collected and disposed of.
We take great care to collect our waste, dispose of it responsibly and document all disposal.
We create and collect many types of waste, including:
We also subcontract out oil collection.
*In a major spill of straight chemical, say 1000L or so, we would subcontract out the sucking up of the chemical, and then do the final clean up ourselves.
Our common waste is mainly disposed of in three locations:
More specialised waste can be more challenging to dispose of.
If there is a high concentration of chemical in our waste, it goes through a testing process. Once the pH is known, we can dispose of it at an appropriate site. Our local council has facilities for disposing of waste with more extreme pH levels.
Contamination, like rodents, is disposed of depending on the site’s facilities. Many of the sites we work at prefer to dispose of the contamination themselves.
We recycle all waste we can.
Oil is difficult. The oil must be taken off the top of the waste, the water from the middle, and the sludge from the bottom. All three parts must be separated and disposed of correctly. Our oil goes to an oil recycling service: ExOil. The water and sludge taken by a local industrial services contractor.
All our waste disposal is documented. For example:
