Turn Coffee Waste into Clean Water and Climate Action
Coffee Waste Doesn’t Have to Pollute
Warm Heart Worldwide in partnership with Coffee Mill and Waste Free '23 are
helping coffee communities in Ethiopia protect water, reduce emissions, and create local income.
In Sidama, Ethiopia, the partnership works with local coffee mills and partners to demonstrate a simple, off-grid solution that transforms coffee husk waste and polluted wastewater into biochar, clean water, and climate action.
This is a practical, community-led approach to sustainability—designed for small and remote coffee mills.

QUICK IMPACT OVERVIEW : What One Coffee Mill Can Achieve

THE PROBLEM
Coffee Waste Is a Hidden Environmental Challenge
Ethiopia produces hundreds of thousands of tonnes of coffee husk each year. Much of it is burned or dumped. At the same time, wastewater from wet coffee mills is often released untreated into rivers.
These practices can lead to:
For many small and off-grid coffee mills, conventional waste treatment systems are not affordable or practical.
Warm Heart Worldwide became involved to help demonstrate a better option.

THE SOLUTION
How We are Addressing Coffee Waste
At a pilot site in Bensa, Sidama, Warm Heart Worldwide supports local implementation of a biochar-based system that addresses both solid and liquid waste from coffee processing.
Step 1: Coffee Husk → Biochar
At a pilot site in Bensa, Sidama, Warm Heart Worldwide supports local implementation of a biochar-based system that addresses both solid and liquid waste from coffee processing.
Step 1: Coffee Husk → Biochar
- Locally built TLUD biochar system
- Powered by a small solar panel
- Constructed using local materials
- Biochar filters polluted coffee wastewater
- Captures organic material and nutrients
- Treated water reused for coffee washing
WHY THIS MATTERS
Environmental, Climate, and Community Impact
Environmental Protection
What was once pollution becomes a resource that supports farming families.
Environmental Protection
- Cleaner rivers and waterways
- Reduced emissions from burned coffee husk
- Long-term carbon storage through biochar
- Reduced freshwater extraction
- Water reuse at the mill
- Biochar sold locally
- Increased crop yields (≈20%)
- Improved livestock health and productivity
What was once pollution becomes a resource that supports farming families.
