Only 10 percent of plastics are recycled globally, with textile-to-textile recycling accounting for less than 1 percent. Against this backdrop, Australian biotechnology firm Samsara Eco has opened its first commercial-scale facility in Jerrabomberra, New South Wales, positioning itself to test whether enzymatic recycling can transition from research to industrial reality.
The facility houses EosEco, a proprietary enzymatic process that deploys AI-designed enzymes to depolymerize mixed plastics—including polyester and nylon 6,6—back into raw chemical building blocks. These outputs can then be repolymerized into virgin-equivalent plastics for applications in apparel, packaging, and automotive supply chains. Unlike conventional mechanical recycling, which typically downcycles materials, the enzymatic route targets closed-loop reuse.
Scale remains the decisive question. According to the company, Jerrabomberra will have the capacity to produce materials equivalent to hundreds of thousands of garments annually, with initial uptake confirmed by partnerships with Lululemon and pilot programs in textiles, automotive, and packaging. The volumes, while notable for a start-up, remain modest compared to the 109 million tonnes of plastics produced annually in Asia-Pacific alone. The firm’s stated plan to build a 20,000-tonne nylon 6,6 plant in Asia by 2028—developed with engineering partner KBR—suggests Jerrabomberra is primarily a proof-of-concept for scaling.
The economics of enzymatic recycling are still opaque. Commercial viability depends on enzyme production costs, process energy intensity, and integration with downstream polymer manufacturing. The Jerrabomberra site includes expanded enzyme production capacity, which could address cost bottlenecks, but no disclosures have been made regarding energy balances or lifecycle emissions. Without independent verification, claims that the materials are “low-carbon” remain untested.
Investor confidence has been strong. Samsara Eco is backed by Temasek, Greycroft, Hitachi Ventures, and Main Sequence, with stakeholders citing the company’s ability to deliver milestones on budget and its potential to create an export-oriented industry. However, investment momentum in recycling startups has historically outpaced commercial outcomes. For instance, chemical recycling projects in Europe and North America have frequently struggled to deliver promised yields at scale, raising questions about whether enzymatic recycling will avoid similar pitfalls.
Policy frameworks provide both opportunity and pressure. Australia’s net-zero commitments and global regulatory trends—including extended producer responsibility schemes and bans on single-use plastics—create a demand signal for circular materials. Yet demand alone is insufficient if supply cannot match on cost and volume. As apparel and consumer goods brands increasingly pledge recycled content targets, the test for Samsara Eco is whether enzymatic recycling can deliver consistent feedstocks at an industrial scale without prohibitive costs.
Beyond plastics, the company has initiated research with The LYCRA Company on spandex recycling and with Deakin University under the Trailblazer Universities Program. If successful, diversification into hard-to-recycle materials could widen its addressable market. But each polymer presents unique challenges, from enzyme design to process economics, making timelines uncertain.
The Jerrabomberra facility thus marks both a milestone and a stress test: it demonstrates the technical feasibility of enzymatic recycling beyond the laboratory, but also exposes the scale, cost, and policy hurdles that must be overcome before such processes can materially shift global recycling rates. For now, Samsara Eco has positioned itself at the forefront of a technology race where credibility will rest less on rhetoric and more on delivered tonnage, verified emissions reductions, and proven market integration.
