Sustainability

Real numbers from a real tannery, not vague claims.

We didn't add sustainability to our process. We built our process to be sustainable - measured in litres recycled, kilograms of salt recovered, and audits passed, not marketing language.

Measured, Not Claimed

Four initiatives, with the numbers behind them.

Lime Water Recycling System

Since 2015

Recycles roughly 600 KL (600,000 litres) of lime water annually, recovers 80% of re-lime liquor, reduces water use by 800 litres per ton of processed leather, and saves 15-25% on lime consumption.

Hair Saving Screen

UNIDO-selected, 2016

Recovers hair from the tanning process instead of chemically dissolving it, cutting Chemical Oxygen Demand (COD) in effluent by 50%. Recovered hair is repurposed as organic fertiliser for green-belt development.

Mechanical Salt De-dusting

Recovers roughly 6 kg of salt per hide (versus roughly 3 kg manually), preventing an estimated 550 tons of salt from entering the environment each year and reducing effluent Total Dissolved Solids (TDS) by 15-20%.

Primary Effluent Treatment Plant (PETP) Upgrade

A mechanical sludge dewatering system independently assessed by the Central Leather Research Institute (CLRI), confirming compliance with environmental discharge norms.

Ongoing Commitments

Sustainability isn't a slogan.

  • Zero-liquid-discharge tannery, treating and recycling process water on site.
  • REACH-compliant chemicals used throughout tanning and finishing.
  • Solar power supplementing the facility's energy load.
  • ISO 14001 environmental management, independently audited.

Compliance
