Use of coffee (Coffea arabica) pulp for the production of briquettes and pellets for heat generation

Abstract: Coffee bean (Coffea arabica) processing generates high amount of residues that are sources of environmental pollution. Therefore, an appropriate solution is needed. The objective of this study was to determine the potential of coffee pulp to produce briquettes and pellets. The study included pulp drying (using air, solar and hot air methods); the production of briquettes and pellets; the evaluation of their energy, physical and mechanical properties; and the evaluation of pellet quality using X-ray densitometr… Show more

“…Similarly to coffee husks, coffee pulp has been studied to be reused for mushroom production (30,31), composting (32), biogas production (33), bioethanol production (34), converted into fuel briquettes or pellets (35), enzymes production such as pectinases or cellulases (36,37), and also for food production (converts coffee pulp into a nutritious flour, which can be used for baking or cooking, or even as an addition to smoothies, soups, or sauces) (38).…”

“…The residual heat may be used to dry out more coffee. The use of coffee pulp for the production of briquettes and pellets for heat generation has recently been proposed [14]. The study included pulp drying (using air, solar and hot air methods); the production of briquettes and pellets; the evaluation of their energy, physical and mechanical properties; and the evaluation of pellet quality using X-ray densitometry.…”

“…The skin and pulp of the coffee beans will be removed and become the residues as they are not needed to process the coffee. As there a wide world production of coffee, it will associate with ecological damages as the residues of coffee can lead to environmental pollution if it is not handled well (Cubero-Abarca et al, 2014). Most of the coffee pulp is dumped into a landfill or river stream directly during wet processing without proper handling of waste (Geremu et al, 2016).…”

“…Most of the coffee pulp is dumped into a landfill or river stream directly during wet processing without proper handling of waste (Geremu et al, 2016). The absence of a method that can utilize the use of coffee by-product is one of the main problems to use the coffee pulp for biomass productions due to the high moisture content (Cubero-Abarca et al, 2014). However, due to the myriad problems such as disposal problems of this by-product and cause environmental pollution, this material has received greater attention compared in the past.…”
