Local researchers have discovered that raw and carbonized Philippine giant bamboo possess distinct combustion properties, opening doors for more efficient biomass energy systems and offering a renewable, locally sourced alternative to imported fuels.
Unlocking Bamboo's Energy Potential Through Science
The study, published in the international journal Advances in Bamboo Science, employed thermogravimetric analysis to examine how the material behaves under heat . Researchers found that raw bamboo breaks down and burns more readily, making it highly effective for processes requiring rapid energy release, such as fast pyrolysis . In contrast, carbonized bamboo demonstrates higher heat resistance, requiring elevated temperatures to ignite and resulting in a much more controlled combustion process, making it suitable for applications relying on stable solid fuels, including charcoal-based energy systems .
These findings were established by establishing key kinetic parameters on the decomposition of both materials, which are important for modeling and optimizing biomass energy technologies . DOST Secretary Renato U. Solidum Jr. emphasized the importance of such research, noting that "studies like this help inform future innovations and strengthen the country's capacity to develop renewable energy solutions amid rising energy demand and growing climate challenges".
From Research to Ready-to-Use Fuel
These findings have paved the way for the development of tangible, sustainable energy products. DOST-FPRDI has developed bamboo pellets, a densified form of bamboo designed for optimum combustion . These pellets have a higher energy density than other biomass materials, such as wood chips and agricultural residues, and are lightweight and easy to transport . According to DOST-FPRDI researcher Anniver Ryan Lapuz, "One cubic meter of these pellets can generate as much as 12.15 gigajoules (GJ)" . These pellets can be used for co-firing in coal-fired power plants to reduce greenhouse gas emissions, as a supplementary fuel for biomass industries, or for household cooking as a cleaner alternative to traditional charcoal .
Another innovation is the charcoal briquette, a compacted mass made from a mix of charcoal fines and a binder . Compared to ordinary charcoal, these briquettes are less messy, burn slowly, give more intense heat, and are almost smokeless . These technologies also open opportunities for small businesses and rural communities to engage in biomass fuel production, creating livelihood opportunities while contributing to a more resilient and localized energy system.
