Title:
PROCESS FOR THE DESTRUCTION OF CEMENT, ASBESTOS-CONTAINING MATERIAL AND/OR OTHER MATRIX MATERIAL BY SIMULTANFEOUSLY SUBJECTING THE MATERIAL TO CAVITATION AND ACID-BASED CHEMICAL REACTION
Document Type and Number:
WIPO Patent Application WO/2019/064069
Kind Code:
A3
Abstract:
An accelerated process for the complete destruction of a matrix material, such as a matrix material including cement and/or asbestos-containing materials (ACMs), is disclosed. The process comprises forming a slurry or suspension by combining the matrix material with an acid solution (including, for instance, acid waste, which can also be neutralized by the process), causing acid-based chemical reactions in the slurry that cause the destruction of the matrix material. Simultaneously to the chemical reactions, the slurry or suspension is subjected to cavitation, which synergistically cooperates with the chemical reactions to accelerate matrix material destruction. The matrix material can be ground and polarized prior to being submerged in the acid solution to form the slurry. The slurry can be subjected to hydrothermal treatment. Inert secondary raw materials (SRMs) that are non-hazardous to the environment and human health can be obtained from the process.
