Diseño de un biocarbón tipo BOCASHI a partir de pericarpio de Café Castillo.

Abstract

In this research, the pericarp, which is a post-harvest residue of coffee, rich in lignin and hemicellulose, compounds that make it usable as a structural support for porous materials, was improved. This allowed the development of a pyrolytic system to obtain biocarbons, which mixed with alkaline oxides, such as calcium oxide (CaO), contributed to the generation of a bokashi, which is characterized by its good retention of organic matter and nutrients. increases soil permeability, reduces greenhouse gas emissions, improves soil porosity, and increases microbial diversity, preventing diseases. The obtained bokashi was characterized by Fourier transform infrared spectroscopy (ATR-FTIR), thermogravimetric analysis (TGA), gas chromatography (GC) volatiles, physicochemical properties and total percentage of nitrogen, establishing that a stable material was obtained with a carbon graphite type, with nitrogen concentrations of 15 to 20% and good phosphorus content. With these results, the bokashi were applied to radish (Raphanus sativus) plants, monitoring the stem, leaf, and root length, establishing that the synthesized materials are appropriate to increase the growth of the studied plants.
