“…Similarly, BCR of all dryer methods are greater than one further confirming the financial viability of the methods (Akinyi et al, 2022;Karim et al, 2019;Melerasha & Kaur, 2020;Nath Subedi, 2011). However, although all methods are financial viable, solar tunnel machine and artificial dryer machines are identified with the highest efficiency of BCR of 1.76 and 1.75 respectively.…”

“…Solar tunnel dryers are an alternative to traditional drying techniques and a contribution toward the solution of the open air drying problems (Karim et al, 2019;Nath Subedi, 2011). A coffee solar drier converts solar energy into heat, which helps to lower the humidity of the coffee grains.…”

“…A coffee solar drier converts solar energy into heat, which helps to lower the humidity of the coffee grains. Studies indicated that solar dryer is known to dry coffee more rapidly because of the roof traps warm air and raising the temperature inside the dryer higher than the ambient air temperature (Karim et al, 2019). However, the quantity of water that can be reduced by evaporation from the coffee grains mainly depends on the air temperature and the velocity of air circulation (Karim et al, 2019).…”

Around 40% of coffee quality is determined in the field, with the remaining 60% determined by post-harvest processing procedures. This demonstrates the significance of coffee processing in improving quality and value. As a result, this article examines the economic viability of Horizon Coffee Plantation Farm's three coffee drying methods: solar tunnel dryer, artificial dryer, and sun dryer. Several economic viability assessments and cost-benefit analyses are used. Furthermore, for each strategy, switching values and sensitivity analysis were done. According to the findings, the gross margin rate for the solar tunnel is Birr 35 per kg of green, followed by Birr 34.75 for the artificial drier machine and Birr 34.2 for the sun dryer method. Similarly, the artificial dryer method was found to be the most viable, with the highest NPV of Birr 89,292,673, followed by Birr 10,016,909 for the solar tunnel method and Birr 175,295 for the sun dryer method, implying that the firm's methods are all economically viable. The BCR and IRR criteria also confirm the same conclusion. The viability of all drying methods remains nearly constant regardless of the potential in costs of production and sales prices. Because investments in all drying methods are non-mutually exclusive, it is advised that the corporation continue to invest in all three drying methods as long as their NPV is greater than zero. However, this finding should be interpreted with caution because the present rise in fuel prices may make the use of artificial dryer methods more expensive and unviable.

“…Semi-dry processing combines the dry and wet process, in which the coffee fruits are mechanically pulped and proceed to dry without removal of the mucilage [75,76]. This method is known as the honey process, because the mucilage is dried along with the coffee beans and produces a honey-like or sugar-like aroma after the drying process.…”

Coffee is consumed not just for its flavor, but also for its health advantages. The quality of coffee beverages is affected by a number of elements and a series of processes, including: the environment, cultivation, post-harvest, fermentation, storage, roasting, and brewing to produce a cup of coffee. The chemical components of coffee beans alter throughout this procedure. The purpose of this article is to present information about changes in chemical components and bioactive compounds in coffee during preharvest and postharvest. The selection of the appropriate cherry maturity level is the first step in the coffee manufacturing process. The coffee cherry has specific flavor-precursor components and other chemical components that become raw materials in the fermentation process. During the fermentation process, there are not many changes in the phenolic or other bioactive components of coffee. Metabolites fermented by microbes diffuse into the seeds, which improves their quality. A germination process occurs during wet processing, which increases the quantity of amino acids, while the dry process induces an increase in non-protein amino acid γ-aminobutyric acid (GABA). In the roasting process, there is a change in the aroma precursors from the phenolic compounds, especially chlorogenic acid, amino acids, and sugars found in coffee beans, to produce a distinctive coffee taste.

“…There are three methods of post‐harvest coffee processing: dry method, wet method, and semi‐dry method ( Exhibit 3). There is no significant difference in the green coffee production generated (23%−24% of cherry); therefore, the choice of method is adjusted to the site conditions (Karim et al., 2019).…”

Currently, coffee is one of the most popular beverages in the world and one of the most important commercial products. However, the industrial processing of this crop generates enormous amounts of waste that are disposed of in the environment, generating a severe pollution problem. This situation raises the need to look for alternatives to use these wastes to reduce their negative impact on the environment. The use of coffee waste to generate biofuels stands out as a viable alternative to mitigate the adverse effects produced by its deposition. This work compiles information on the types of coffee processing, production, and alternatives for the use of waste generated during its processing, highlighting its exploitation in the generation of biofuels.
