Verification Mechanisms
Verification mechanisms are the tools to provide the required and desired proofs of waste events. By categorizing these mechanisms into distinct types, each targeting specific areas of validation, it's possible to create a comprehensive system that stakeholders can trust.
Verification Types
Verification mechanisms are designed to validate various types of information across various domains. Here's a breakdown of the key verification mechanisms tailored to different categories of data:
| Mechanism | Target Validation |
|---|---|
| Financial | Money flows and value perceptions from individual transactions and broader market perspectives. |
| Commercial | Commercial relationships, agreements, and contractual obligations between entities. |
| Compliance | Credentials, certifications, and adherence to regulations mandated by authoritative bodies or industry standards. |
| Operational | Physical handling and manipulation of materials within operational processes. |
| Technical | Studies or assessments of the specific properties of materials or contexts. |
Supporting Documents
Supporting documents are critical for validating waste processes and ensuring that all aspects are thoroughly documented and verifiable. Transactional documents are issued on events and specific moments, while non-transactional documents are not dependent on individual occurrences. This guide provides detailed definitions and applicability for each document type, categorized by their verification domain:

Document Validation Layers
Each document, apart from its name, format and other details, may include additional information on its involved entities, in the form of signatures or issuance, providing more information to increase its credibility:
- Issuance. Validation by the entity that generated it, providing authenticity.
- Signature. Validation indicating consent or approval by the signing party.
The types of entities that can validate by issuance or signature a document are the following:
| Validation Layer | Definition | Example |
|---|---|---|
| Internal | Validation within the same organization, ensuring in-house verification. | An internal work order issued and used within the organization |
| External | Validation by an external independent organization, offering third-party verification. | Certification of a product’s quality by an independent testing laboratory |
| Regulatory | Validation by a regulatory body, providing an official level of authentication and compliance. | A waste management company receiving approval from the regulator to handle hazardous waste |
