Scaling a Natural Alternative to Plastics
What the Company Does
PHAXTEC is a fast-growing start-up commercializing polyhydroxyalkanoates (PHA)—a breakthrough natural biomaterial to replace fossil-based, non-biodegradable plastics. Its patent-protected process converts renewable and waste greenhouse gases into PHA, unlocking sustainable solutions for packaging, personal care, agriculture, textiles, automotive, and more. PHA can replace over 50% of the world’s fossil plastics.
Current Landscape
The plastics industry is at a turning point. Global regulation, consumer demand, and corporate sustainability commitments are pushing urgently for alternatives to fossil-based, non-biodegradable plastics. While several companies have entered the bioplastics sector, solutions fall short in scalability, true biodegradability, and cost-efficiency. PHAXTEC is positioned at the forefront of this transformation, combining material cost and performance with authentic sustainability.
Company Birth Story
The company was born from decades of experience in plastics and biopolymers. Its founder, Anindya Mukherjee, worked with multiple PHA start-ups and witnessed both the promise and the challenges of bringing PHA to scale. Driven by the conviction that the world needs a plastic alternative that is safe for people and planet—and offer the convenience of plastics—PHAXTEC was launched.
Solution
PHAXTEC has developed a proprietary process that transforms renewable and waste greenhouse gases into PHA. Unlike conventional plastics, PHA is fully biodegradable in soil, water, and marine environments—leaving no microplastic behind. Unlike other PHA competitors, PHAXTEC focuses on scalability, cost parity with plastics, and versatile applications. The company’s vision is to make PHA the material of choice across industries, accelerating the shift to a circular economy. Early successes include pilot collaborations with packaging and personal care brands, as well as proof-of-concept projects in agriculture and textiles.
Customer Impact
PHAXTEC enables brand owners to achieve ambitious sustainability targets without compromising on product performance. Consumers benefit from safe, eco-friendly products that reduce plastic pollution in oceans, landfills, and everyday life. By turning greenhouse gases into valuable materials, PHAXTEC also contributes directly to climate change mitigation.
Team Culture
The team unites scientists, engineers, and entrepreneurs who share a passion for sustainable innovation. Their culture is defined by curiosity, collaboration, and a mission-driven spirit. Whether in the lab or with industry partners, the team is motivated by one goal: to create materials that will make plastics pollution a thing of the past
