STABILIZATION OF BIOWASTE THROUGH A NATURAL DEHYDRATION PROCESS AND THE INTRODUCTION OF THE BIOBIN / ESTABILIZACIÓN DE RESIDUOS BIOLÓGICOS MEDIANTE PROCESO DE DESHIDRATACIÓN NATURAL E INTRODUCCIÓN DE BIOBIN

Resumen

Biowaste is an essential raw material for either Waste to Energy recovery or natural fertilizer production. Due to its structural instability; handling, and storage of biowaste is challenging, especially when it comes to prolonged storage and transportation. Freezing or drying of wet biowaste at source is the optimal method to retain physical and chemical structure of biomass. The currently applied energy intensive process shrinks the interest of applying these methods at the source of biowaste generation (i.e., small kitchens, Homes, and offices). This provokes the need for a device that facilitates biowaste stabilization at low energy demands and relatively lower purchase and operational costs. Biowaste is introduced into the waste-bins of the source of generation at a very early stage (i.e., before decomposition). However, it is easier to dehydrate the wet-biowaste at room temperature with small current of air circulation under controlled conditions. The following description is a short insight to a new concept of a domestic dehydrator (BioBin) dedicated to biowaste stabilization through dehydration. The present article has as fundamental objectives, to present the results of the evaluation of an experiment at a domestic scale of the drying of household waste, and from the results achieved in the evaluations at a domestic scale to propose a container called BioBin that could be generalized for drying of biological waste, mainly fruit and vegetable remains in the kitchens, in city homes.
