TDPA™ innovative technology is not the ultimate or only solution to problems related to the prevalence of packaging materials in the environment, but it is an important tool to effectively reducing the proliferation of non-degradable plastics in our environment. Very importantly, TDP’s production process is virtually identical to the unmodified products while retaining the same physical properties. This, coupled with their affordability, differentiates them from other types of biodegradable plastics so that they are readily adopted and provide these benefits to the greatest number of consumers and therefore to the environment.

TDP™ products can be reused, recycled and then discarded. After been discarded, degradation starts. The degradation is carried out by a process of oxo-biodegradation, initiated by TDPA™ which reduces the molecular weight of the material over a pre – determined period from18 – 24 months. The plastic does not just fragment, but is consumed by micro-organisms after the additive has reduced the molecular weight. This process continues until the material has biodegraded to nothing more than CO2, water and bio mass.

Recognition

Local Research

The University of Hong Kong has researched TDP™ bags on biodegradability and results have shown that TDP™ bags biodegraded 50% in 180 days. More importantly, the result has indicated that this trend would continue beyond 180 days until total degradation.

Food Contact Approval

TDP™ products fully comply with FDA requirements in the United State and the EFSA in Europe. With compliance to food contact requirements, TDP™ products could be applied to food contact applications such as food packaging and food cutlery.

ASTM D6954-04

ASTM (American Society for Testing and Materials) standards are benchmarks for stakeholders so that they are authoritative and indicative. Establishment of ASTM D6954-04, Standard Guide for Exposing and Testing Plastics that Degrade in the Environment by a Combination of Oxidation and Biodegradation, indicates the formal recognition of the oxo-biodegradation technology internationally.

ASTM D5272 Outdoor Exposure Testing

According to ASTM D5272 Outdoor Exposure Testing, TDP™ bag has been gradually degrading after exposure to sunlight. After 55 days, it has obviously degraded into plastic fragments. In contrast, conventional bag has not degraded at all.

Award

Plastic Products incorporating TDPA™ have also been credited for their contribution to the environmental preservation. Awards include “The Millennium Products” Award presented by the former British Prime Minister, Mr. Tony Blair and “The Green Apple Award” by an authoritative environmental organization have been received.
