About Us

Pioneering the Future of Clean Extraction

What We Do

At Amaranthus Biorefinery, we turn fruit waste into natural value.
Using proprietary supercritical CO₂ extraction, we convert citrus peels and native botanicals into high-purity, solvent-free extracts like limonene and diosgenin.

We combine:

  • 🌿 Green chemistry that protects people and the planet
  • ♻️ Circular business models that empower local communities
  • ⚙️ Modular biorefinery tech that scales anywhere, quickly and affordably

Our products power solutions in nutraceuticals, pharma, wellness, and clean-label consumer goods — all without toxic residues.

Our Values

Sustainability
We design every process to reduce emissions, water use, and waste — aiming for carbon-negative outcomes.

Equity
We operate through cooperative ownership, ensuring fair income and empowerment for local producers and waste collectors.

Innovation
We continuously improve our tech, from modular engineering to bioactive preservation — pushing the boundaries of green extraction.

Transparency
From supply chains to product composition, we build traceable systems that earn trust.

Mexican Engineering, Global Impact
We are proudly rooted in Mexico and committed to delivering world-class solutions from local talent and resources.

Years of Expertise & Professionalism

Founded in 2016, Amaranthus Biorefinery is a Mexico-based climate-tech company transforming agricultural waste into high-value natural extracts using solvent-free supercritical CO₂ technology.

Our work stands at the intersection of green chemistry, circular economy, and social innovation, redefining how bioactive ingredients are extracted, who benefits from that value, and how scalable clean technologies can drive inclusive growth.

Mission

To be a world-class producer of biomolecules through Mexican supercritical extraction technology, promoting its global adoption as a sustainable cornerstone of modern biorefinery applications.

Vision

To lead Latin America and the world in clean, sustainable biorefining, recognized for delivering the highest-quality natural extracts powered by original Mexican engineering.


We aim to become the trusted partner for organizations seeking eco-friendly, traceable, and toxin-free solutions grounded in the principles of Green Chemistry.

What Makes Us Different

TRL 7-certified clean extraction process

Our technology has been validated at Technology Readiness Level 7, demonstrating real-world performance in a pilot plant environment. It’s proven, scalable, and ready for industry deployment.

Powered by circular cooperative business models

We don’t just process biomass — we empower the people behind it. Our cooperative model allows local waste collectors and small producers to co-own the supply chain and share in the value creation.

Climate-positive technology that avoids toxic solvents

Our supercritical CO₂ extraction process uses no hexane, no heptane, and no synthetic chemicals. It’s clean for the planet, safe for workers, and better for your products — with the potential to become carbon-negative.

Focused on scientifically validated natural ingredients

We develop extracts backed by research and efficacy, starting with limonene and diosgenin. Our R&D ensures bioactivity is preserved and purity is maximized in every batch.

🇲🇽 Proudly Designed, Built, and Operated in Mexico

From engineering to execution, our modular biorefineries are created with Mexican talent, technology, and ingenuity — proving that world-class innovation can emerge from Latin America.
