GREENPOWER conducted a research study on the pyrolysis of compressed sugarcane bagasse pellets with the goal of producing high-quality biochar from sugarcane bagasse that meets strict international certification standards.
Feedstock and Its Characteristics
- Material: Pellets made from sugarcane bagasse
- Moisture content: Approximately 10%
- Ash content: Around 5%
These sugarcane bagasse pellets were selected for their consistent density and moisture levels, ideal for controlled bagasse pellets pyrolysis. A full fuel analysis confirmed compliance with technological requirements for efficient thermal conversion.
Pyrolysis Results and Biochar Composition
The pyrolysis of sugarcane waste produced sugarcane bagasse biochar with the following properties:
| Parameter | Value |
| Moisture | ~1% |
| Ash content | ~13% |
| Volatile matter | ~7.5% |
| Fixed carbon | ~79% |
| Heating value (HHV) | ~6994 kcal/kg |
In addition to its favorable composition, the biochar showed a low concentration of polycyclic aromatic hydrocarbons (PAHs) and an ideal H/Corg ratio, confirming compliance with biochar EBC certification requirements — specifically the EBC-Agro Organic level.
Conclusions
- Quality: Sugarcane bagasse biochar produced from pellets demonstrated superior structural stability, low moisture, and high fixed carbon content.
- Energy Efficiency: The biochar’s heating value is significantly higher than the raw material, improving energy output per unit.
- Environmental Value: Its stable carbon matrix makes it suitable for carbon sequestration biochar projects and long-term soil applications.
Benefits for GREENPOWER
- Sustainable Waste Management: Turning sugarcane residues into valuable biochar for agriculture supports waste reduction and circular economy models.
- Compliance with International Standards: Certification under EBC opens doors for export, regulated use, and participation in biochar production incentive programs.
- Economic Opportunities: High-grade biochar derived from pyrolysis sugarcane waste can be monetized through carbon credits, sustainable agriculture services, and carbon removal markets.
