An innovative agro-processing company in Côte d’Ivoire successfully transformed cocoa husk waste into valuable biomass fuel pellets using an advanced biomass pellet machine.
This comprehensive case study documents how agricultural waste conversion created a profitable circular economy business while addressing environmental challenges in the world’s largest cocoa-producing nation.
Côte d’Ivoire’s Cocoa Industry and Waste Challenge
Côte d’Ivoire is the world’s largest cocoa producer, accounting for 40% of global cocoa production. In 2025, the country produced 2.2 million tons of cocoa beans, generating approximately 4.4 million tons of cocoa husk waste (cocoa pods represent about 80% of fresh pod weight).
A 52-year-old agro-industrial entrepreneur from Abidjan had been operating a cocoa processing facility for 15 years. Facing increasing environmental regulations and waste disposal costs, he sought a sustainable solution to convert cocoa husk waste into valuable products.
Cocoa Husk Waste Challenges
- Massive waste volume: 4.4 million tons of cocoa husk generated annually in Côte d’Ivoire
- Disposal costs: 35,000-50,000 XOF per ton for waste removal and landfill fees
- Environmental impact: Decomposing husks release methane (25x more potent than CO₂)
- Pest attraction: Waste piles attract rodents and insects, spreading disease
- Water pollution: Rainwater runoff from waste piles contaminates water sources
- Missed opportunity: Cocoa husk has high calorific value (4,200-4,500 kcal/kg)
“We were paying fortunes to dispose of cocoa husks,” explained our customer. “The waste was piling up, creating environmental problems, and costing us money. I knew there had to be a better way to handle this biomass. Converting waste into energy seemed like the perfect solution.”
The Solution: Biomass Pellet Production from Cocoa Husk
After extensive research on biomass utilization and consultations with Taizy Machinery’s renewable energy specialists, he invested in a complete biomass pellet production line designed specifically for cocoa husk processing.

Cocoa Husk Pellet Production Process
The biomass pellet production line converts raw cocoa husk into dense, uniform fuel pellets through a series of processing steps.
Production Process Steps
- Raw material collection: Cocoa husks collected from processing facilities (moisture 45-55%)
- Crushing: Hammer mill reduces husk to 3-5mm particle size
- Drying: Rotary dryer reduces moisture from 45% to 10-12%
- Pelleting: Pellet mill compresses material through a 6mm or 8mm die at high pressure and temperature
- Cooling: Cooler reduces pellet temperature from 80-90°C to ambient +5°C
- Sifting: Vibrating sifter removes fines and oversize particles
- Packaging: Finished pellets bagged in 15kg or 25kg bags
| Parameter | Value |
|---|---|
| Raw material moisture (input) | 45-55% |
| Dried material moisture | 10-12% |
| Pellet diameter | 6mm, 8mm (optional 10mm) |
| Pellet length | 10-30mm (adjustable) |
| Pellet density | 1.1-1.3 g/cm³ |
| Pellet durability | ≥95% |
| Production temperature | 80-90°C (natural lignin activation) |
| Hourly capacity | 1,000-1,200 kg/h |
| Daily production (8 hours) | 8-9.6 tons |
| Monthly production (26 days) | 208-250 tons |
