This research aims to assess the sustainability and feasibility of the production of Pleurotus ostreatus using ground coffee seed and pulp waste as substrate, and then demonstrating its economic profitability. Different raw materials were characterized as substratum and technical aspect production in the greenhouse for P. ostreatus were analyzed with the economic analysis for financing the project. With this technique, we found an option of sustainable model production, which concedes added value to the agricultural wastes from coffee processing once is used as a source of substrates for the production of Pleurotus ostreatus. The results obtained from the production of mushrooms through the waste from ground coffee and pulp are feasible and profitable in San Salvador. The use of coffee waste in the production of mushrooms will reduce the waste or biomass resulting from the coffee industry, therefore, it is a sustainable alternative in environmental terms. Moreover, economic analyses from PI's were 3.047052287, given that it was >1, consequently, the project was accepted, while the IRR was

This paper aims to assess the technical, economic, and financial viability of cultivation of mushroom from coffee waste and pulp. The raw material characteristics and technical aspects were analyzed. In techno economic analysis, the investment is defined, and the financing of the project were explained. It is believed that production of mushroom from coffee waste and pulp is feasible as well as profitable in San Salvador. Use of coffee waste in the production of mushroom will prevent its damping in landfills and thus be friendly to environment as well.

This research details an effort to develop a nutritious snack that can alleviate, and combat problems associated with undernourishment product was developed using corn, cassava, and moringa (or teberinto). Two samples of the product were made, with 1 and 2% moringa, along with corn (60%) and cassava (39%) and were tested through a sensory analysis with 15 panelists. The better product was determined by applying the ANOVA to the results of the sensory analysis. The selected sample was the one containing 1% moringa. The product was subjected to microbiological tests for quality and bromatological tests and to ascertain its chemical composition. Results from both tests met the requirement of established standards. Three physicochemical determination (protein, moisture and ash) also provided favorable results. Thus combining these foods into a snack may contribute to mitigation of undernourishment.
