Our production side streams consist of by-products and process waste. By-products include, for example, the most nutrient-rich ash that is sold for fertilising, and lime fractions that can be burnt to calcium oxide and used in other industries.
The majority of the process waste is utilised for material use and for energy generation. Only 1% is delivered to landfill.
In addition to by-products and process waste, our operations generate other non-hazardous waste, such as municipal waste and construction waste, and some hazardous waste.
