One heap, three problems
Every day, agri-food processing sites produce residues. Cassava peelings from attiéké making, spent grain, pulp, husks. With no outlet for them, they end up in heaps.
01 Environment
The rotting heap
- Organic waste left in the open ferments.
- It releases methane, a gas that warms the climate far more than carbon dioxide.
- The liquid that seeps out reaches soils and waterways.
- The heap draws insects and rodents.
02 Social
Cooking in smoke
Many households and small businesses still cook with firewood or charcoal.
That smoke is breathed in every day, first of all by the people cooking.
Firewood is taken from nearby forests and hedgerows.
03 Economy
Paying twice
- Sites often pay to have their waste removed.
- They also pay for the energy they burn to cook and dry.
- Yet the matter they throw away could supply part of that energy.
The same heap can become a source of gas.
Phase 1 targets a first 5,000 to 10,000 L (5 to 10 m³) unit on a processing site.
