Ginger Rhizome Waste Shows Potential as Alternative Energy Source

Indonesia's National Research and Innovation Agency (BRIN) is exploring the potential of ginger rhizome waste as a sustainable alternative energy source. A research team is developing technology to transform this agricultural byproduct into biobriquettes, aiming to support the nation's energy transition and circular economy initiatives.

Waste biomass of ginger rhizome can be utilized as a raw material for biobriquettes to support biomass-based alternative energy.

The focus is on utilizing waste from the production of essential oils and other plant-based products, which often generate significant solid waste. Ginger rhizome waste is particularly promising due to its high lignocellulose content, specifically a lignin content of 45.98 percent, which is crucial for creating biobriquettes with a high carbon value.

Waste solid ginger rhizome has a high lignin content of 45.98 percent. Through the pyrolysis process, this waste can be improved in quality.

Researchers are converting the waste into a solid fuel through a process called carbonization, followed by molding with different types of adhesives. This method aims to produce biobriquettes that meet quality standards for solid fuels, offering stable combustion performance and a valuable, environmentally friendly energy alternative. The study evaluates various adhesives to optimize the physical, mechanical, and thermal characteristics of the final product, enhancing its potential as a value-added resource.
