Intervention Phase

What did we do?

Container Assessment

Comprehensive analysis of post-consumer sodium cyanide containers, determining their initial physical and chemical state.

Cleaning Process

Implementation and technical validation of the controlled triple-wash protocol for the removal of hazardous traces.

Accredited Analysis

Rigorous testing in laboratories accredited by INACAL to guarantee the accuracy of chemical results.

TECHNICAL REFERENCE

"Analytical precision was the cornerstone for the waste reclassification in this mining project."

Case Resolution

The analytical results demonstrated that, after the optimized washing protocol, the metal containers did not present quantifiable concentrations of cyanide.

Final classification: Non-hazardous waste.

This technical validation enabled efficient management under MINAM guidelines and final handling through duly authorized EO-RS operating companies, guaranteeing total regulatory compliance.

Efficient Management

Strict compliance with international toxicity standards and circular economy.

Success Summary

Main Achievement: Technical Test

Conclusive confirmation of non-toxicity after controlled washing, eliminating environmental risk and the hazardous burden of the metallic material.

100% Residue-Free

Operational Efficiency

Substantial improvement in waste logistics and reduction of operational costs associated with final disposal.

Basis for Valorization

The technical study served as legal and scientific foundation for the future valorization of metals, promoting the circular economy at the Yauliyacu mining unit.

Frequently Asked Questions

Why were these containers evaluated?

It was imperative to confirm the real hazardous status after their initial use with cyanide to determine whether the internal washing process was sufficient for safe disposal.

What did the laboratory analysis show?

The analysis showed cyanide concentrations below quantifiable limits, validating the effectiveness of the cleaning process to convert hazardous waste into inert materials.

How should these containers be managed in the end?

They must be managed through authorized Solid Waste Operating Companies (EO-RS), allowing their reuse as high-purity metal scrap.
