- ÍtemRestringidoComposting of activated sludge catalyzed by pineapple solid waste.(Universidad EARTH, 2019-12) Chonza, Joseph; Caicedo Jiménez, Luis MiguelThe agricultural sector generates approximately 80 % of total solid waste at a global level per year, and the correct treatment of these wastes has been a challenge. This study focused on the hypothesis to catalyze the composting process of Activated Sludge (AS), using Pineapple Peel (PP), and Pineapple Leaf (PL). These three materials are abundant organic solid wastes in Costa Rica. The three materials were combined to make composts in the proportions: (A) 100 % AS, (B) 50%-50% AS+PL, (C) 50%-50% AS+PP, and (D) 50%-25%-25% AS+PL+PP. Each treatment lasted 90 days and was repeated 10 times. Each batch had an initial mass of 500 g. Treatment (B) had the fastest degradation rate (0,029 day-1 approximately; R2=0,77); while treatment (A) had the slowest degradation rate (0,021 day-1 approximately; R2 = 0,70). Generally, the content of macro and microelements after composition showed to be in the same recommended ranges as industrial fertilizers, making the resulting compost an alternative option to improve soil fertility and regenerate soils. The composting process of AS was catalyzed by organic waste such as PL and PP, improving the degradation rate 20 % to 40%.
