Corporate electronic waste is frequently treated as a logistical disposal issue. This is technically insufficient. Retired computers, servers, storage media, mobile devices, networking equipment and other electronic assets may concentrate data-protection, environmental, audit, financial and governance risks when they leave an organisation without a controlled evidence trail. This technical report proposes an evidence architecture for corporate e-waste management in Brazil. The framework integrates secure collection, controlled intake records, weighing, asset classification, data sanitisation, media destruction, environmental traceability, avoided CO2e documentation and a final audit-grade evidence dossier. The framework is grounded in Brazilian data-protection and solid-waste governance references, including LGPD, PNRS and the Brazilian reverse-logistics framework for electrical and electronic products, while also using European and international references such as GDPR, the WEEE Directive, NIST SP 800-88, the Basel Convention, ISO 14040/14044 and the GHG Protocol as benchmarks for buyer-readiness, auditability and environmental documentation. The report does not present avoided CO2e as a carbon credit, offset or financial environmental asset. Avoided CO2e is defined strictly as a documented environmental performance indicator derived from material recovery and avoided-emission factors. The result is a structured model for boards, CFOs, DPOs, legal departments, procurement teams, sustainability leaders, auditors and international buyers that need more than a generic waste certificate. The model converts corporate e-waste disposal into a risk-control and evidence-generation process.
