Biomass Energy Potential in Colombia
Colombia possesses a diverse array of organic resources that can be converted into sustainable energy. Biomass—organic material derived from plants and animals—offers a promising pathway for the country to diversify its energy matrix by utilizing agricultural residues, forestry waste, and urban landfill gases.
Key Facts
- Annual biomass power potential is estimated at over 16 GWh.
- Agricultural residues are the largest contributor, providing 11,828 MWh/yr.
- The Urabá region produces over 1 million tons of bananas annually from 19,000 hectares.
- Coffee plantations could generate 190 million m3/yr of biogas.
- Major city landfills could support an installed capacity of 47 MW.
Analyzing Colombia's Biomass Sources
While the current biomass contribution represents less than 0.1% of Colombia's total electricity production, the distribution of potential energy sources is broad. The primary drivers are agricultural by-products, followed by liquid biofuels and forestry residues.

Agricultural and Forestry Contributions
Agriculture residues lead the potential output with 11,828 MWh/yr. Forestry also plays a role, with natural forest residues contributing 698 MWh/yr and planted forest residues adding 442 MWh/yr. These sources represent a significant opportunity to turn waste into power.
Biofuels: Bioethanol and Biodiesel
Liquid biomass in the form of biofuels also contributes to the energy potential. Bioethanol accounts for 2,640 MWh/yr, while biodiesel provides 658 MWh/yr.
Regional Powerhouses: Urabá and Coffee Plantations
Specific regions in Colombia show immense potential for specialized biomass production. In the north of the Department of Antioquia, the Urabá region manages approximately 19,000 hectares of banana plantations, yielding more than 1 million tons of produce annually.
Furthermore, coffee plantations offer a massive opportunity for biogas (a mixture of gases, primarily methane, produced by the anaerobic digestion of organic matter). It is estimated that 190 million m3/yr of biogas could be generated, equivalent to 995,000 MWh or approximately 85,000 TOE/yr (Tons of Oil Equivalent per year).
Urban Waste-to-Energy Potential
Beyond the countryside, Colombia's urban centers provide a viable source of energy through landfill gas recovery. The landfills serving the four largest cities—Bogotá, Medellín, Cali, and Barranquilla—are estimated to have the potential for an installed capacity of 47 MW, which represents 0.3% of the country's current installed capacity.
| Source | Potential (MWh/yr) |
|---|---|
| Agriculture Residues | 11,828 |
| Bioethanol | 2,640 |
| Natural Forest Residues | 698 |
| Biodiesel | 658 |
| Planted Forest Residues | 442 |
