WesCEF - Environmental stewardship
Wesfarmers Chemicals, Energy and Fertilisers (WesCEF) is committed to being a leader in environmental protection by reducing its environmental impact and seeking to ensure the sustainability of its operations. Since the end of the 2020 financial year, WesCEF developed its aspiration to achieve net zero in its operations by 2050. Water security is a business-critical risk at WesCEF’s CSBP Kwinana site with current and future threats to availability, reliability and cost of traditional water supply options. CSBP Kwinana’s water consumption increased by 20 per cent this year, corresponding with higher production in water intensive processes.
During the year, WesCEF completed its long-term water sustainability strategy for the CSBP Kwinana site. This involved assessing available water sources and options to improve wastewater treatment, including the revitalisation of the site’s three hectares of purpose-built wetlands. The wetlands are an important part of CSBP’s wastewater management, naturally treating approximately 2.5 million litres of nutrient-rich wastewater each day. The strategy will ensure the site’s long-term water supply, plant reliability and effluent discharge security, and allow CSBP the opportunity to use climate-independent water sources.
A focus area for next year includes the potential construction of a wastewater recycling plant. The plant will remove metals from the wastewater before directing clean water back to CSBP’s processing plants.
Legacy waste represents an ongoing environmental risk due to potential impacts on the environment and/or neighbours. WesCEF’s contaminated sites strategy advanced during the year with investigations completed at CSBP’s Dalwallinu, Albany, Geraldton and Esperance sites, and progress was made at the Bunbury and Kwinana sites. During the year, WesCEF had a significant increase in volumes of waste recycled as a result of construction and demolition works at CSBP Kwinana and the regional fertiliser depots. A key performance measure for WesCEF is diversion of waste from landfill, with 90 per cent of waste recycled or reused during the year.
