- Description: Project to prevent wet mills, required to process coffee, from discharging waste water and organic coffee skins into the local rivers. The project improves river water quality, essential for the local communities for washing, watering livestock and even drinking.
- Specificity: Separation of coffee skins for composting and use of Vetiver wetlands to filter processing waste water and prevent contamination of the river.
- Impact: Improvement of standards of living for all people living near water courses
SEVERAL WET MILL TRANSFORMATION STEPS:
Technical support to the wet mills to reduce and track water use
Creation of Vetiver wetland for waste water management
Composting of coffee skins to return to farmers
Monitoring of rivers to assess impact on water quality
"I have always feared the harvest season due to the bad smells produced by pollution. Since we use Vetiver systems, I use river water again to wash. It has stopped pollution."
Zoom on wet mills: coffee washing essential for high quality coffee
> Clean water enables improvement of coffee quality and thus producers' income
> Improved community relations for the wet mills and less likelihood of wet mill closures by government .
