PROCEDURE FOR OBTAINING A BIO-STABILIZED SUBSTRATE FOR FOREST FROM THE INTEGRAL CYCLE OF TREATMENT OF URBAN SOLID WASTE.

摘要

Procedure to obtain a forest substrate from the complete recycling of materials recovered from the treatment of urban solid waste, which consists of the following phases: - (A): separation of waste into a wet fraction and a dry fraction , - (B): treatment of the dry fraction and obtaining of Derivative Waste Fuel (Refuse-Derived Fuel, RDF) - (D): obtaining of solid materials, - (F): treatment of products derived from the production of RDF in a gasifier and obtaining electrical and / or hydrogen energy, and production of an inert residue in the form of vitreous mineral granulate, - (C): biological stabilization of the wet fraction, - (E): refining of the stabilized material with production of: a Stabilized Organic Fraction (SOF), sanitized processing residues with controlled sizes and RDF to be sent for gasification; - (G): stratification of the forest substrate consisting of: a) At least one layer of stabilized organic fraction (4) with a homogeneous matrix: b) At least one layer of sanitized inert processing residue (3) with controlled sizes derived from phase (E); c) At least one layer of vitreous mineral residue (2) with controlled sizes derived from the gasification phase (F) and d) A layer consisting of soil and biostabilized compost (1).
