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.

Amaranthus Biorefinery offers a clean alternative:
We transform local fruit waste into high-value natural extracts using supercritical CO₂ extraction technology — without toxic chemicals.

Diosgenin

Advantage: a sustainable alternative to synthetic synthesis

Sourced from: Mexican Barbasco (Wild Yam)

Market size: US$7.9B (contraceptive industry)

Role: natural precursor for hormone-based pharmaceuticals

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.
