TOTO-TOA® Enhanced materials are engineered to perform reliably throughout their entire useful life.
Durability supports circularity.
Reuse, recycling, and long-life products depend on materials that do not weaken prematurely.
Premature breakdown compromises performance, safety, and recyclability.
The challenge isn’t whole plastic products.
It’s the microplastic fragments created through wear, damage, and end-of-life processing.
While many biodegradable plastics focus on whole-part breakdown.
TOTO-TOA® takes a different path: durable materials in use, with responsibility at the fragment stage.
POST-FRAGMENT
BIODEGRADATION
FRAMEWORK
Definition
The evaluation and optimisation of TOTO-TOA® Enhanced materials behaviour after materials are reduced to fragment size through normal use and end-of-life processes.
All while maintaining full durability, performance, and recyclability during the product’s intended service life.
In Practice
Products made from TOTO-TOA® Enhanced materials are designed to remain durable and recyclable in use.
If fragments are generated through wear, damage, grinding, shredding, or disposal, those fragments are evaluated for biodegradation under defined, controlled conditions.
Persistence
Environmental persistence is governed by fragment size, surface area, and microbial accessibility, not by intact product performance.
This clearly separates:
Durability during use, and
Environmental fate after fragmentation.

Outcomes depend heavily on thickness, geometry, and exposure.
For large or thick products, degradation onset may be negligible or unmeasurable within realistic timeframes.
Approaches designed to meet whole-part compostability standards often compromise long-term mechanical stability and durability.
Whole-product tests are often short-term, landfill-specific, or focused on disintegration rather than true mineralisation.
Industrial composting infrastructure is limited, and most facilities do not accept plastic articles due to contamination risk.
our framework is not
A whole-product biodegradation claim.
A compostability claim.
An oxo-degradable or oxidation-driven approach.
A technology designed to accelerate embrittlement.
A substitute for recycling or circular systems.
fragmentation is not engineered — it occurs naturally.
Biodegradation is evaluated only after fragmentation and only under defined conditions.
we do not use:
Oxo-degradable metal salts.
Additives that trigger premature breakdown.
Designs that weaken product integrity.
Unqualified whole-product biodegradation claims.

ENABLES
consistent material behaviour
repeatable testing and substantiation
clearer and more defensible claims
higher confidence for OEMs and supply chains
circularity grounded in reality.
Circularity is not about making plastic disappear.
It is about:
Using materials for as long as possible.
Keeping plastics in managed systems.
Minimising environmental leakage improving outcomes if leakage occurs.
