Australia’s Geelong Refinery, operated by Viva Energy, has stepped into a new era of plastic recycling innovation, marking a significant milestone that not only advances the country’s sustainability ambitions but also challenges long-standing industry practices. The partnership between Viva Energy and Alterra, a leader in advanced plastic waste technologies, introduces a revolutionary approach that converts problematic plastic waste into valuable resources, making strides toward a circular economy. This unique collaboration demonstrates how plastic pollution can be tackled through cutting-edge technology integrated seamlessly into existing industrial processes—an achievement with far-reaching environmental and economic implications.
At the core of this breakthrough is Alterra’s proprietary thermochemical liquefaction process, a marked departure from traditional recycling. Conventional mechanical recycling has long been hamstrung by the complexity and contamination of post-consumer plastics, especially soft and mixed types, which typically end up discarded in landfills or incinerators. Alterra’s technology tackles this challenge head-on by chemically breaking down end-of-life plastics into their original chemical building blocks, producing plastic pyrolysis oil (PPO). This oil is essentially a recycled feedstock—comparable in quality to fossil-derived inputs but created from otherwise unusable waste. The Geelong Refinery’s recent trial processed over 9.5 tonnes of PPO, marking the largest volume of recycled plastic oil refined in Australia and proving its feasibility and scalability on an industrial level.
The significance of this trial extends beyond the technical marvels of advanced recycling. Traditionally, the plastics industry has been trapped in a linear cycle of production, use, and disposal that contributes heavily to environmental degradation and resource depletion. Alterra’s chemical recycling technology disrupts this cycle by capturing the embedded carbon and material value locked within complex plastic waste streams. By converting these materials into PPO, the process effectively “recycles” plastics that were previously deemed unsuitable for recovery. Crucially, the PPO produced is chemically compatible with existing refinery infrastructure, meaning Viva Energy can integrate it without costly or extensive modifications. This compatibility paves the way for producing new food-grade recycled plastics and low-carbon fuels, reinforcing sustainability without sacrificing economic viability.
This development is more than a story about new technology—it’s a narrative of strategic shifts within the energy sector. Viva Energy is redefining its role from a conventional fuel refiner to a proactive “Energy Hub” focused on integrating biogenic, circular, and low-carbon solutions. This transition reflects a broader global trend toward decarbonization and sustainable industrial practice. To this end, collaborations are key. Partnering with companies like Cleanaway and Klean Industries, Viva Energy is building a robust ecosystem for industrial-scale plastic waste diversion, including sorting, pre-treatment, and chemical recycling facilities designed to handle hard-to-manage waste streams. These partnerships underscore the understanding that no single actor can solve the plastics crisis alone. The initiative not only produces recycled plastics but also contributes to sustainable fuel production, aligning with evolving environmental regulations such as ultra-low sulfur gasoline and decarbonized diesel.
The multifaceted benefits of this integrated approach cannot be overstated. From an environmental perspective, diverting waste plastics from landfill and ocean pollution addresses some of the most pressing ecological concerns—marine habitats, soil quality, and air pollution all stand to benefit. Moreover, reducing reliance on virgin fossil feedstocks helps cut greenhouse gas emissions throughout the plastics and energy supply chains, reinforcing Australia’s commitments to carbon neutrality. Economically, the innovative reuse of existing refinery infrastructure optimizes capital expenditures, maximizing asset utility while fostering local employment opportunities in emerging green sectors. This synergy between environmental stewardship and economic development speaks directly to national priorities on waste reduction and innovation in recycling technologies. As global markets intensify their demand for sustainable materials and regulations become more stringent, Australia’s capacity to produce certified recycled feedstocks will grant it competitive advantages both domestically and internationally.
In essence, the milestone achieved at the Geelong Refinery with Alterra’s technology heralds a transformative approach to plastic waste management. By converting more than 9.5 tonnes of plastic pyrolysis oil derived from end-of-life plastics into feedstocks fit for refining into high-quality products, this progress validates the promise of advanced chemical recycling. The initiative embodies a convergence of visionary environmental strategy, technological innovation, and collaborative industry efforts—setting a replicable precedent for circular plastics economies not just in Australia but worldwide. In this emerging paradigm, waste is no longer a burden but an opportunity; sustainability and economic progress move hand in hand as the plastics challenge is recast into a story of resourcefulness and renewal.
