In the pursuit of sustainable energy sources, biomass briquettes have emerged as a remarkable solution that tackles two pressing challenges: providing an eco-friendly alternative to traditional fuels and reducing waste.
Biomass briquettes tap in to the power of organic waste materials, transforming them into a condensed and efficient fuel source.
The global initiative known as Vision 2030 has set forth a clear goal to transition towards cleaner sources of energy and reduce reliance on fossil fuels. As part of this vision, there is a strong focus on promoting sustainable development and the adoption of environmentally friendly practices. Clean energy, including biomass briquettes, plays a pivotal role in achieving these targets.
Biomass briquettes offer immense potential for clean energy generation, as they utilize organic waste materials that would otherwise contribute to pollution or go to waste. By harnessing biomass resources and converting them into briquettes, we can significantly reduce greenhouse gas emissions and combat climate change.
Moreover, the production and use of briquettes provide economic opportunities for local communities, fostering a sustainable and inclusive development .
TYPES OF BRIQUETTES
Rice Husk Briquettes:
Rice husk, the residue from rice grain processing, has proven to be an exceptional biomass for briquette production. With its optimal moisture content of 8% to 12% and convenient granulation, rice husk requires no further grinding or drying. The low lignin content restricts the briquette diameter to below 75 mm without adding binders. These briquettes find their prime application in high-temperature boilers and furnaces, thanks to their ability to withstand intense heat without sintering
Here’s an outline of the process to create briquettes from rice husks:
Collection and Drying: Collect the rice husks after the rice grains have been separated. Thoroughly dry the husks to reduce their moisture content. Low moisture content is important for efficient briquette production.
Grinding: Use a grinder or pulverizer to grind the dried rice husks into smaller particles. This increases the surface area, making it easier to compress into briquettes.
Mixing and Binder Addition: Mix the ground rice husk powder with a binder material to improve the briquette’s cohesion and stability. Common binder materials include starch, clay, or other natural adhesives. Ensure that the binder is evenly distributed throughout the mixture.
Briquette Formation: Use a briquetting machine or a manual press to compress the mixture into briquettes of the desired shape and size. Apply pressure to achieve a compact and solid briquette.
Drying and Curing: Allow the freshly made briquettes to dry and cure in a well-ventilated area. This helps to remove any remaining moisture, making them more stable and easier to handle.
Storage and Utilization: Store the rice husk briquettes in a dry place to maintain their quality. They can be used as a renewable energy source for heating, cooking, or other industrial applications.
Sawdust Briquettes:
Produced from the remnants of sawmills and woodworking processes, sawdust briquettes have gained popularity for their versatility and availability. Sawdust, a fine particle size material, can easily be compacted into uniform briquettes through the application of moderate pressure. Due to its higher lignin content compared to rice husk, sawdust briquettes offer greater flexibility in terms of shape and size. They are widely used for domestic heating, cooking, and even industrial applications
Sawdust briquettes are a common form of biomass fuel created from sawdust, which is the byproduct of wood processing. Here’s an outline of how sawdust briquettes are made:
Collection and Drying: Collect sawdust from wood processing operations or use waste sawdust from woodworking activities. Ensure that the sawdust is relatively dry or dry it further to reduce its moisture content.
Grinding (Optional): If the sawdust particles are too large, you can use a grinder or pulverizer to break them down into smaller pieces. This can help improve the compressibility of the sawdust.
Mixing and Binder Addition: Mix the sawdust with a binder material to enhance the cohesion and stability of the briquettes. Common binder materials include starch, clay, or other natural adhesives. Ensure that the binder is evenly distributed throughout the mixture.
Briquette Formation: Use a briquetting machine or a manual press to compress the sawdust mixture into briquettes of the desired shape and size. Apply pressure to achieve a compact and solid briquette.
Drying and Curing: Allow the freshly made briquettes to dry and cure in a well-ventilated area. This helps remove any remaining moisture, making them more stable and easier to handle.
Storage and Utilization: Store the sawdust briquettes in a dry place to maintain their quality. They can be used as a renewable energy source for heating, cooking, or various industrial applications.
Coconut Shells
Coconut shell briquettes are an excellent source of biomass fuel, known for their high calorific value, low moisture content, and sustainable nature. Coconut shells, the hard outer part of coconuts, can be effectively converted into briquettes through the following process:
1. Collection and Drying: Collect coconut shells after the flesh and water inside the coconuts have been removed. Ensure that the shells are thoroughly dried to reduce their moisture content. This is important to ensure efficient briquette production.
2. Grinding and Carbonization: Grind the dried coconut shells into smaller particles using a grinder or pulverizer. Then, subject the ground shells to a carbonization process. Carbonization involves heating the shells in a controlled environment with limited oxygen supply, which removes volatile components and increases the overall carbon content, resulting in charcoal.
3. Mixing and Binder Addition: Mix the charcoalized coconut shell powder with a binder material, such as starch, clay, or any other natural adhesive. The binder helps hold the briquettes together during compression and burning. Thoroughly blend the mixture to achieve a consistent composition.
4. Briquette Formation: Use a briquetting machine or a manual press to compress the mixture into briquettes of the desired shape and size. Apply pressure to create compact and stable briquettes.
5. Drying and Curing: Allow the freshly made briquettes to dry and cure in a well-ventilated area. This helps remove any residual moisture and ensures that the briquettes attain the desired hardness and stability.
6. Storage and Utilization: Store the coconut shell briquettes in a dry place to maintain their quality. They can be used as a sustainable energy source for cooking, heating, or industrial purposes.
Always consider sustainable sourcing of coconut shells and adhere to environmentally friendly practices during the briquette production process.!
Sugarcane bagasse
Sugarcane bagasse can indeed be used as a valuable source for biomass briquettes. Sugarcane bagasse is the fibrous residue left after sugarcane stalks are crushed to extract the juice. It is a byproduct of the sugar industry and has potential as a biomass fuel due to its high cellulose content.
