IGO SUSTAINABILITY REPORT 2020

Non-mineral waste management IGO takes a holistic approach to the way we manage our waste, further enhanced by our strategy to be Proactively Green and responsible environmental stewards. We seek to positively influence environmental and social impacts of our products through the value chain, which includes the way we manage our waste products. We manage our waste in accordance with the IGO Group Environmental Standard 7 – General Waste Management. In FY20, we began a new Group-wide, employee-led initiative to reduce the amount of non-mineral waste that we generate and improve the way we manage it. This initiative was founded on the application of the waste-management hierarchy of ‘avoid, reduce, reuse, recycle’. In mining, main waste streams include tyres, oils and greases, scrap metal, rubble and office and kitchen consumables. The new employee led I-GO Green Waste Reduction Initiative is focused on the latter, with incredible results in the first six months, recycling 46 tonnes of waste originally destined for the Nova Operation on-site landfill. Read more in the following sustainable waste management case study. During FY20, 1,040 tonnes of materials were recycled at our Nova Operation, including organic waste, co-mingled waste (including glass, hard plastics and cardboard) and scrap metal. We reduced our average annual landfill volume by 30 per cent. MAKING A DIFFERENCE IN SUSTAINABLE WASTE MANAGEMENT In line with our commitment to making real and proportionate contributions that respond to global environmental challenges, IGO engaged Perth-based waste and recycling specialist, Write Solutions, to help better manage our waste streams and provide alternative solutions to disposal at the Nova on-site landfill. This employee-driven program led to the establishment of the I-GO Green Waste Reduction Initiative. Following a review of workplace opportunities, the program established three new sustainable waste pathways: compostable organics, co-mingled recycling, and glass. As far as we are aware, we are the first mine site in Western Australia to roll out a compost solution for food waste and organics, and the first to utilise BioPak compostable food packaging. The other streams are focused on recycling our cardboard, glass, cans, hard plastics and paper. In parallel, this program resulted in the elimination of 100 per cent of our single use plastic food packaging, by transitioning to sustainable food packaging supplied by BioPak. This plastic-fee packaging alternative, now used by our almost 500 site employees, can be recycled in the organics waste pathway. The first six months since the introduction of this initiative have shown incredible results, including: • 46 tonnes of waste have been recycled (diverted from the Nova on-site landfill); • Nova landfill volume has been reduced by 30 per cent; • we have replaced 300,000 units of single use plastic; and • contamination levels are now below five per cent. The Green Waste Reduction Initiative complements other employee-driven and managed waste management programs at IGO, which have been implemented over the last two years. These include: • a press to recycle all cardboard; • recycling of aerosol cans, batteries, light globes and tubes, scrap steel and waste oil; • establishing a bioremediation pad to remediate and reuse hydrocarbon contaminated soils; and • contributing to various community donation programs, including the donation of wooden cable drums to the Norseman Men’s Shed to be repurposed into other items; donation of mattresses to the St Patrick’s Community Centre; and the donation of gym equipment to Shalom House in Perth to support its rehabilitation programs. Through the various waste management programs, we are working to significantly reduce landfill waste at the Nova Operation thereby limiting our impact on the environment and ensuring responsible product stewardship.
