Volume 14 • Issue 3 | 2017 | ASIA Miner | 23 CONSTRUCTION of the world's first ex- tra-large tyre recycling plant in Perth, West- ern Australia, will start soon. Following preparation of conceptual drawings and commissioning of final drawings, construc- tion of the plant is expected to commence by February 2018. The venture is a collaboration between Tytec Group and Green Distillation Tech- nologies (GDT), a global award-winning tyre recycling technology company. They have jointly established Tytec Recycling to un- dertake economic green recycling of large tyres, referred to as OTR or off the road tyres, which are classified as those with rim sizes ranging from 25 to 63 inches. GDT has developed world-first technology that will recycle end-of-life tyres into oil, car- bon and steel using their 'destructive distil- lation' process. Transport of tyres from mine sites to the recycling plant will be undertak- en by Tytec Logistics, which has over 75% of the national OTR logistics market. Currently there is no means of recycling OTR tyres and the usual method of dispos- al in Australia is to bury them in a dumping area on mine sites, or in an EPA nominat- ed dumping area. The GPS coordinates of the dump together with the serial number of each tyre disposed of in this way must be provided to the EPA. The recycling benefits by this method are considerable as by using the GDT tech- nology a tyre weighing 3.5 tonnes will yield 1500 litres of oil, 1.5 tonnes of carbon, and the steel reinforcing which can go back to the tyre manufacturer for reuse. The Hyder Report in 2013-14 estimated that there are 155,000 tonnes of OTR end- of-life tyres of various sizes generated in Australia each year of which 79.4% remain on site. The recycling of OTR tyres in Australia is the 'tip of iceberg', according to GDT's chief operating officer Trevor Bayley, who attend- ed MINExpo, the world's biggest mining expo in Las Vegas last year. "The Australian recycling potential for OTR tyres is a fraction of the world market as during MINExpo we received enquiries from mining companies in Mexico, Colum- bia, Brazil, Canada, the US and Chile, and the market in these countries is immense as they have large mining industries and no current economic green means of recycling used OTR tyres. "The move to build the world's first pro- cessing plant for OTR tyres comes after more than 12 months of logistical research and development work at the Tytec Recy- cling R&D plant, which is a section of the GDT facility in Warren, New South Wales. This work has been seeking a solution to the problem of how to handle a 4-tonne tyre with a diameter of 4 metres or more through a complex process at sufficient volume to make it economically viable," he said. GDT has developed proven world-first technology that recycles end-of-life tyres into oil, carbon and steel using its 'destruc- tive distillation' process. The world's first recycling plant for extra-large tyres will be built in Perth. World's first OTR tyre recycling plant for Perth organisms affected by humans. This principle aims at conserving habi- tats, which is fundamental to the existence of any species. The Gaia principle embodies the understanding that all the Earth sys- tems, such as climate, oceans, biological systems, cryosphere and even the lithosphere constitute a single, holistic self-regulating system in dynamic equilibrium. It holds that the existence of life influences glob- al climate and chemistry in ways that keep the planet perpetually hab- itable. Stewardship is a sort of 'catch-all' principle, effectively requiring adherence to all the other principles. Concepts of IE Researchers frequently tussle with complex issues that are extremely difficult to understand. Concepts, in the form of metaphors, analogies and similar ways of thinking are used to help analyse the circumstanc- es in real life that they represent. The metaphor of industrial activity emulating a biological ecosystem is ubiquitous. It represents flows of materials and resources throughout an industrial system as the metabolism of nutrients and symbioses in biological ecosystems. It indicates ways industrial organisations should interact with one another and with the environment. The concepts of Systems Theory address issues of interconnected- ness, especially the operation of feed-back loops and dynamic equi- librium. The notion of complexity, involving non-linearity and probability, contribute to assessments of eventuality and risk. The notion of scale is particularly significant in IE and contributes to the concept of emer- gence; the perception of human impact on the natural environment at different scales. IE in practice Sustainable development can only progress through action. A prereq- uisite for IE in practice is realistic analysis, currently done with tools such as life cycle assessment and materials flow analysis. Politics and fund- ing are hugely influential but sustainable development ultimately de- pends on adopting appropriate strategies to change human behaviour. Some apply at an economy-wide, or national scale, others operate on the scale of single organisations or even small groups. Prominent among large-scale strategies are: de-materialisation to reduce the quantity of materials used in an economy; de-carbonisation to reduce dependence on carbon; and conservation, the overarching strategic imperative to preserve resources generally e.g. by repeatedly reusing materials etc. Organisational strategies include: Green Chemistry, being cleverer and more ecological in combining materials etc.; Cleaner Production, being more careful about how things are produced; and Industrial Symbiosis, arrangements between organisations to share resourc- es and especially to use industrial waste. The Circular Economy has gained traction recently, notably among the general populations in developed economies. Conceptually, the strategy is industrial symbiosis aimed at minimising post-consumer waste throughout an entire economy. It relies on extensive collabo- ration and stakeholder 'license to operate'. Given the very brief synopsis in this article, one might well ask: what bearing could IE have on mining? Answer - for the time being: Watch this space!
