  1. EEO Key Element 3 – Information, Data & Analysis Chin Ching Soo – Specialist Greenhouse and Energy Aug 2012

  2. A leading global business that delivers value at each stage of mineral and metal production. Employs approximately 68,000 people in over 40 countries. Finds, mines, develops and processes natural resources. Fulfils vital consumer needs and improves living standards. Sustainable development is at the heart of its operations. Rio Tinto at a glance Bauxite, alumina and aluminium Borates Coal Copper Diamonds Gold and silver Gypsum Iron ore Molybdenum Salt Talc Titanium dioxide Uranium Other products, including nickel

  3. Rio Tinto Alcan in Australia • Rio Tinto Alcan is an integrated aluminium business. Our operations in Australia are: • Weipa Bauxite Mine • Yarwun Alumina Refinery • QAL Refinery (non managed) Weipa Yarwun & QAL

  4. The way we work • Rio Tinto Alcan operations are large energy users. • Management and reduction of energy use is and has always been a priority • Energy costs and emissions are integrated into ‘The way we work’ so as to retain our ‘license to operate’

  5. Energy data collection & analysis • Our existing energy data collection systems include: • Sub metering of electricity and gas for major equipment • Historian database system for process data • Fuel management system • Our existing energy performance and analysis includes: • Daily lean boards for key energy metrics and KPIs • Performance benchmarks • Best practice sharing across sites • Enthalpy models and pinch analysis of Bayer refinery process • To date complying with EEO has added time and costs to our process.

  6. Preparing for KE 3 in an Assessment • Don’t reinvent the wheel • document what you already do • take actions to address the gaps • Compile an ‘Information Pack’ to describes how KE 3 is met • format documents to clearly show how you meet compliance

  7. Developing an Energy Mass Balance • Hold workshops with key personnel in each plant area • Objective is to discuss energy use, data sources and analysis • Workshops gets the team ready for the Idea Generation Sessions. • Our practical approach with EMB data • Good data is essential for management of key energy and materials • used NGER data for site level • Used sub-metering for process level • For completeness, list variables that have a small impact and did not pursue measurements, e.g. waste water

  8. Linking Key Element 3 with Key Element 4 • Ideas to Opportunities • Collate ideas from energy studies e.g. energy audits or pinch analysis, plans and idea hoppers • Idea Generation Sessions • Breakdown of energy use for each process area • Performance benchmarks and data trends • Proportion of fuel use in process area compared to site use • Document the links of KE 3 and KE 4 for compliance
