Resource Efficiency Targets
This project implemented targets to reduce consumption of non-renewable resources across our Australian manufacturing sites.
This project involved determining and implementing reduction targets for greenhouse gas emissions, municipal and groundwater use and waste to landfill at our Australian manufacturing sites across Australia. This has now been extended to our north American manufacturing sites.
In 2012, four working groups were established across our Australian manufacturing operations to research, consult and develop their own three year site targets in relation to the use of energy and water and the creation of greenhouse gas emissions and wastes. More than 75 site specific initiatives were identified and agreed to by our local site managers, which were rolled into national targets. The working groups consisted of the site personnel with direct responsibilities for resource reductions, and the outcomes were as follows:
• Major Energy – this group concentrated on reducing energy use at our large, energy intensive manufacturing sites and set a target to reduce energy and emissions by 3.5 percent per tonne by 2015 at our Gibson Island ammonia manufacturing plant. A 4% reduction was achieved in 2013 and maintained in 2014. In 2015, the reduction per tonne of product was 7% against our baseline year. Read about the new targets we have set in this year in our 2015 Online Sustainability Report.
• Minor Energy – this group aimed to achieve energy use reductions at our smaller manufacturing sites and set several reduction targets which were achieved early in 2013 and have been maintained through to 2015. These include a 12 percent energy reduction per tonne of single-super phosphate fertiliser at our Geelong plant in Victoria, Australia.
• Water – this group worked to reduce water use and set two reduction targets totalling 10% per tonne across our Asia Pacific manufacturing sites. Although one project has been delayed indefinitely, our Phosphate Hill fertiliser manufacturing site reduced its water use by 3% per tonne of product produced in 2014, and by 7% against 2014 usage in 2015. This site has set a new target for 2016, as described in our 2015 Online Sustainability Report.
• Waste – this group worked to increase recycling and reduce the impacts and costs associated with all types of solid waste-to-landfill, aiming for an absolute 10% reduction by 2015. Multiple site based targets were set, resulting in a 15% reduction to landfill in 2013. In 2014 the reduction was increased to 21%, and in 2015 Australian waste-to-landfill was reduced by over 40% against the 2011 waste-to-landfill baseline.
In 2015, our north American manufacturing sites set two reduction targets associated with major projects. Firstly, we continued to invest in NOx reduction technology, with work beginning on the design of a Selective Catalytic Reduction unit for the Louisiana, Missouri, nitric acid plant, which will be installed in 2016. The SCR abatement unit will reduce NOx emissions by 91% and GHG emissions by 5% at the site by 2017. This translates to a 30% reduction in NOx emissions per tonne of nitric acid produced globally in 2017.
Secondly, also during 2015, construction of the 800,000 tonne per annum ammonia plant remained on track and on budget for production in the third quarter of 2016. When operational, the Louisiana ammonia plant will apply the industry’s leading technology and will be among the most efficient plants of its kind in the world, employing gas purifier technology and recapturing steam for reuse. This project supports our target of a 2% reduction in greenhouse gas emissions per tonne of ammonia produced globally in 2017.
