Groundnut Shell Briquettes
Groundnut shell briquettes are compressed blocks or logs made from groundnut shells, which are the outer coverings of peanuts (Arachis hypogaea). After the peanuts are harvested and shelled, the outer shells remain as waste material. Instead of being discarded or left to decompose, these shells can be processed into briquettes, providing an environmentally friendly and sustainable energy source.
The process of making groundnut shell briquettes involves crushing and grinding the shells to create a fine powder. The powder is then compacted under high pressure to form the briquettes. Like other biomass briquettes, groundnut shell briquettes are typically produced without the use of additional binders or chemicals, relying on the natural lignin present in the groundnut shells to hold the briquettes together.
Importance and Benefits
- Waste utilization: By using groundnut shells to make briquettes, this agricultural waste is put to productive use, reducing its environmental impact.
- Renewable energy: Groundnut shells are a renewable resource, and their use as briquettes promotes sustainable energy practices.
- Low carbon footprint: When burned, groundnut shell briquettes release less carbon dioxide compared to fossil fuels, making them a more environmentally friendly energy option.
- Cost-effective: Groundnut shells are often readily available at low cost or even as waste products, making the briquettes an economical energy source.
