Electronic waste, or e-waste, is one of the fastest-growing waste streams in the world. As schools, universities, and corporations frequently 'refresh their fleets' of laptops and data centre technology, a significant amount of hardware becomes obsolete. While some devices can be refurbished and sold, many are too old or broken. In a traditional linear economy, these items often end up in landfills. However, organizations like RenewIT are changing this narrative by collecting old equipment to reclaim valuable materials, specifically focusing on the plastic components that housing IT hardware, turning a waste problem into a resource opportunity.
Australian government bodies and environmental NGOs monitor waste statistics and provide guidelines on electronic waste management.
The transformation from waste to resource happens in a specialized facility known as a MICROfactorie, developed in partnership with UNSW (University of New South Wales). The process begins with the careful disassembly of hardware. Using specific intellectual property (IP), workers identify exactly which plastics are suitable for recycling. Once sorted, these plastics undergo 'thermal transformation.' This involves subjecting the plastic to controlled heating and cooling cycles to reshape the polymer chains without degrading them. The result is a high-quality spool of filament that is ready to be fed into standard 3D printers to create new objects.
University research centres in Australia are leading the world in sustainable materials research and micro-manufacturing technology.
The ultimate goal of this technology is to achieve 'Zero Waste' through a Circular Economy. Unlike a linear economy (make, use, dispose), a circular economy keeps materials in use for as long as possible. By converting waste plastic into remanufactured filament, the material is given a second life. This is described as a 'horizontal solution' because the resulting 3D printed products can be used in almost any industry—from medical to automotive to education. This approach creates a 'win-win' scenario: it reduces environmental pollution, recovers economic value from waste, and fosters sustainable manufacturing practices for humanity.
National science agencies and industry groups in Australia are actively developing roadmaps to transition the country toward a circular economy.
