Young Coconut Waste Processing: Briquetted or Pelleted!

When the weather is very hot like recently, drinking coconut water is very refreshing. This is because coconut water, apart from meeting the body's fluid needs, also meets the needs of electrolytes (ionically charged minerals found in cells, tissues and body fluids) which the body really needs. This electrolyte plays a role in supporting the activity of cells and body tissues and maintaining the balance of body fluid levels. When the body loses electrolytes due to physical activity or dehydration, consuming coconut water can help replace lost electrolytes and restore body fluid balance. There are many sellers of young coconut ice, especially in big cities. Apart from being sold in glasses, young coconut water is also sold in the form of whole young coconuts. The combination with young coconut flesh adds to the deliciousness of the drink. But it turns out that the waste from young coconuts is very polluting and has not been processed or used properly. The volume of young coconut waste is quite large, in fact, in the city of Makassar, South Sulawesi,  it is estimated that there is 15 tons/day of young coconut waste.

Young coconut waste can be processed into briquettes or pellets. Biomass densification technology is suitable for application as a solution for young coconut waste. The young coconut waste needs to be reduced in size (size reduction), namely with a shredder and hammer mill, then dried with a dryer before being compacted / densified into briquettes with a briquetting machine or into pellets with a pelletiser (pelleting machine). By briquetting or pelletizing the waste, it can be used as fuel or energy source for SMEs or boilers in industry. Many SMEs or processing industries can use this fuel. Apart from being environmentally friendly, it is also easy to use. Simple furnaces can be developed to use these briquettes and pellets.

Indonesia is famous for its seductive land of coconut islands. This is because the extent of coconut plantations in Indonesia reaches around 3.7 million hectares, most of which are smallholder plantations. The extent of these coconut plantations places Indonesia as the owner of the largest coconut plantations in the world. Coconut trees mainly grow along the coast, and indeed Indonesia also has the second longest coastline in the world, after Canada.
