Obtención de biochar a partir de residuos maderables en el sur de quito y su uso como fertilizante en suelos

Abstract

In the South of the Metropolitan District of Quito there are several sawmills, carpentry, which their timber waste is thrown into garbage dumps and do not have a recycling process; For this reason, this experimental work was carried out; in order to take advantage of timber waste with the production of biochar. A sampling was carried out in different points of sawmills in the South of Quito, in which the 3 most representative and generated timber waste was asked and collected; With the collection of this waste, biochar was made by pyrolysis. This pyrolysis process was carried out by means of the muffle which introduced the wood and was taken to different temperatures to obtain biochar; considering that it is a reaction without oxygen. Once obtained in biochar, a nutrient analysis was carried out in order to know what would be the best fertilizer and could help the recovery of soils. Through this research we want to make it clear that timber waste is very useful and that it is not necessary to have a final disposal taking into account the cost-benefit for the city.
