POLYBUTYLENE ADIPATE TEREPHTHALATE

PBAT

PBAT is designed to break down completely under industrial composting conditions, leaving no toxic residues. This just means that when it's buried in soil, it breaks down completely and leaves no toxic residues behind and degrades quickly.

POLYLACTIC ACID

PLA

PLA is a monomer derived from renewable, organic sources such as corn starch or sugar cane. PLA uses less energy in production and emits less greenhouse gases during decomposition than plastic.

ZEA MAYS

CORN STARCH

Corn starch is a natural organic material derived from corn, renowned for its rapid biodegradability. Harvested from the kernels of corn, this eco-friendly substance is widely used in various applications, from cooking to bioplastic production. Its ability to break down quickly makes it an excellent choice for sustainable and environmentally conscious products.

WHAT IS TÜV OK CERTIFIED COMPOSTABLE? ↓

TÜV Austria’s OK Home Compost certification ensures that a product will fully break down in a home composting environment—without the high heat of industrial facilities. It means the material decomposes safely within 52 weeks at ambient temperatures and leaves no toxic residue behind. It also confirms the product is non-toxic to plants and soil.

This certification is considered one of the most rigorous compostability standards in the world. Products must pass strict tests for biodegradability, disintegration, ecotoxicity, and heavy metal content. Testing is done by independent labs and often takes several months. Because of its credibility and difficulty, it’s a gold standard in compostable packaging.

WHAT IS BPI-CERTIFIED COMPOSTABLE? ↓

BPI (Biodegradable Products Institute) Certification is an internationally recognized program that verifies the compostability of products according to ASTM standards, specifically ASTM D6400 or ASTM D6868. Administered by the Biodegradable Products Institute, a non-profit organization, this certification ensures that products meet stringent criteria for biodegradability, disintegration, ecotoxicity, and compost quality.

The BPI certification process involves several key steps:

  1. Testing and Verification: Products must undergo rigorous testing by independent, BPI-approved laboratories to ensure they can break down in industrial composting facilities without harming the environment. These tests assess the product's ability to biodegrade, disintegrate into non-distinguishable pieces in compost, and not release harmful substances.
  2. Compliance with Standards: The product must comply with ASTM D6400 or D6868 standards, which outline the necessary conditions and timeframes for compostability. These standards are regularly updated to reflect current scientific understanding and industry practices.
  3. Certification Mark: Once a product passes the necessary tests, it is awarded the BPI Certification Mark. This mark indicates to consumers, composters, and regulators that the product is compostable and meets all required standards. The mark must be displayed on the product and its packaging to help differentiate it from non-compostable items.
  4. Environmental Benefits: BPI-certified products contribute to reducing landfill waste and supporting the composting infrastructure by providing a clear market signal for compostable materials. These products, when composted, enrich the soil with nutrients, promoting a circular economy.
