A. Standard Abstract

The Whole Process Plastic Integrity™ (WPPI™) Standard establishes a
structured methodology for evaluating plastic exposure across the full
operational lifecycle of a
product or material system.

Unlike product-only plastic claims, WPPI™ evaluates plastic interaction
across the entire production chain including raw materials, production
systems, equipment contact, auxiliary materials,
packaging, storage, and logistics.

The standard introduces transparent classification tiers that allow
organizations to declare the level of plastic exposure control within their operational processes.

WPPI™ is designed for cross-industry application including manufacturing, food production,
agriculture, pharmaceuticals, textiles, industrial materials, and supply chain systems.

B. Canonical Definition

Whole Process Plastic Integrity™ (WPPI™) is a structured process
and material integrity standard defining conditions for
transparent disclosure and structural control of plastic exposure across
all operational layers involved in the creation,
handling, storage, and distribution of a product.

Plastic integrity under WPPI™ is defined as the measurable minimization,
documentation, and management of both intentional plastic use
and non-intentional plastic contamination throughout the production lifecycle.

C. Scope

WPPI™ applies to operational systems including:

• manufacturing processes
• food and beverage production
• agricultural and herbal processing
• pharmaceutical production
• textile and fiber systems
• industrial component manufacturing
• packaging production
• raw material processing
• B2B supply chains

Evaluation may include:

• raw material inputs
• production equipment contact
• auxiliary materials
• packaging systems
• storage environments
• transport and distribution systems

D. Plastic Integrity Classification Model

WPPI™ introduces three process-based classification tiers.

Tier 1 — Process Plastic Controlled (PPC)
At least 95% plastic-free across the documented production process.
Plastic components may be used where technically unavoidable, provided they are transparently disclosed.

Tier 2 — Process Plastic Minimal (PPM)
At least 98% plastic-free across the documented production process.
No intentional plastic components in the primary product structure.
Trace contamination must be documented.

Tier 3 — Whole Process Plastic-Free (WPPF)
At least 99.5% plastic-free across the documented production process.
No intentional plastic components permitted.
Only analytically negligible contamination may exist.

E. Intentional vs Non-Intentional Plastic Exposure

WPPI™ distinguishes between two structural exposure categories.

Intentional Plastic Use
Examples include:

• structural plastic components
• plastic packaging
• polymer coatings or liners
• polymer processing aids
• synthetic composite materials

Non-Intentional Plastic Contamination
Examples include:

• microplastic transfer
• equipment abrasion
• transport contamination
• environmental particulate exposure
• auxiliary system cross-contact

Integrity classification depends on declared presence and documented control.

F. Process Integrity Layers

WPPI™ evaluates six operational integrity layers:

• Raw Material Integrity Layer
• Production Integrity Layer
• Equipment Contact Layer
• Auxiliary Materials Layer
• Packaging Integrity Layer
• Logistics & Storage Layer

Integrity classification depends on transparency across all relevant layers.

G. Fail-State Conditions

A WPPI™ classification becomes invalid if:

• intentional plastic exceeds the declared threshold
• undisclosed plastic components are identified
• process boundaries are not clearly defined
• process documentation is incomplete
• declared exposure controls cannot be demonstrated

H. Implementation Modes

WPPI™ may be applied under three operational models:

• Self-Declaration Transparency
• Structured Implementation
• Third-Party Laboratory-Supported Verification

The standard itself does not require certification.
It establishes a structural framework for transparent process disclosure.

I. Compatibility

WPPI™ operates within the Environmental Integrity Standards architecture
and may function alongside:

• Origin Eco™ Standard
• Soil Integrity™ Standard
• Water Integrity™ Standard
• Carbon Integrity™ Standard
• Air Integrity™ Standard

WPPI™ introduces a Process & Material Integrity layer complementing environmental transparency standards.

Canonical Closing Statement

Plastic integrity is not defined by the final product alone.

It is defined by transparency across the entire production process.
