Clean Extraction for a Circular Future
At Amaranthus Biorefinery, we harness supercritical CO₂ extraction — a solvent-free, energy-efficient process that transforms local fruit waste into high-purity, bioactive natural extracts. Our technology is TRL 7-certified, validated in real operating conditions, and built for global scalability.

The Problem
The Food Waste Crisis
- 🚛 3.6 million tons of citrus fruit waste discarded annually in the UK alone.
- 🧺 Over 32,000 tons of produce wasted every year at Mexico City’s Central de Abastos — 45% of it fruits and vegetables.
- 🔬 These discarded materials contain valuable bioactive compounds — often left untapped or extracted using toxic solvents like hexane and heptane.
The Industry Challenge
Traditional extraction methods create:
Health risks for operators and consumers
Environmental pollution and solvent waste
Low bioactivity retention and high energy usage

What is Supercritical CO₂ Extraction?
Supercritical CO₂ is a state where carbon dioxide behaves like both a gas and a liquid. In this form, it can penetrate biomass and extract natural compounds without using toxic solvents like hexane or heptane.
✅ 100% solvent-free
✅ GRAS-certified (Generally Recognized As Safe)
✅ Preserves temperature-sensitive bioactives
✅ Zero toxic residues
✅ Closed-loop recapture system
✅ Minimal water use, low energy footprint
Why It Matters
Traditional extraction often involves:
- ❌ Toxic solvents
- ❌ Fossil fuel derivatives
- ❌ High water and energy use
Amaranthus offers a climate-positive alternative that is:
💡 Better for next-generation wellness and pharma solutions
🌿 Safer for humans
🌍 Gentler on the planet

How It Works
1
Feedstock: We source citrus waste and native botanicals (e.g., orange peel, barbasco root)
2
Extraction: CO₂ is pressurized into a supercritical state and passed through the biomass
3
Separation: Bioactive compounds (e.g., limonene, diosgenin) are separated and purified
4
Recapture: CO₂ is recovered and reused in a closed-loop system
5
The result? High-yield, clean extracts with low environmental impact.
