Samsara Eco EosEco Enzymatic Recycling

Samsara Eco is an Australian biotech company founded in 2021 by Paul Riley in partnership with Main Sequence, the Australian National University and Woolworths. It targets plastics and textiles that are hard to recycle, such as nylon 6,6, polyester and mixed or dyed fabric blends, which usually end up in landfill or incineration.

Its EosEco process uses enzymes designed with a proprietary AI platform. Post-industrial and post-consumer waste is collected and pre-processed, plastic-specific enzymes depolymerise it into monomers, and the monomers are purified to remove colourants (AA and HMD for nylon 6,6, TPA and MEG for polyester). Polymerisation partners then turn them into virgin-identical resin. Customers are apparel, packaging and automotive brands and their material suppliers.

• AI enzyme platform: designs plastic-specific enzymes for speed, scale and precision.
• Depolymerisation: breaks nylon 6,6, nylon 6 and polyester back into their original monomers.
• Purification: separates colourants and dyes to produce pure AA, HMD, TPA and MEG.
• Mixed feedstock handling: processes blended, coated and dyed post-consumer textiles.
• Supply chain fit: monomers go to polymerisation and yarn partners such as NILIT.
• Scale-up capacity: Jerrabomberra plant plus a planned 20,000-tonne nylon 6,6 commercial plant in Asia.

Vietnamese garment exporters supplying global sportswear brands can source enzymatically recycled nylon and polyester to meet buyer requirements. Textile manufacturers can supply post-industrial offcuts as feedstock. Fibre producers can explore joint development or offtake partnerships for an Asian plant.

Recycled monomers are virgin-identical, so brands can substitute fossil-based nylon and polyester without changing product quality. The process accepts tricky feedstocks such as mixed, coated and dyed materials. Output plugs into existing polymerisation and spinning supply chains. The company positions the materials as low-carbon alternatives that help brands meet circularity targets and new regulations.

Global apparel brands are setting recycled-content targets and textile EPR rules are emerging, while less than 1% of textiles are recycled into new textiles. Asia is the centre of synthetic fibre production, and Samsara Eco plans its first commercial plant in the region, which matters for Vietnam's large textile and garment export sector.

Founded in 2021 and headquartered at its Jerrabomberra plant in NSW, Australia, opened in September 2025. The company reports $150 million raised, including a US$65 million Series A+ co-led by Temasek. KBR is designing its first commercial nylon 6,6 plant, due in 2028. Partners include lululemon, NILIT, The LYCRA Company and Deakin University; a General Manager for Asia is based in Singapore.
