Zero waste stores have become an important part of the sustainable retail movement. As more consumers look for environmentally responsible products, retailers are also rethinking the packaging they use.
However, switching to compostable packaging is about more than replacing conventional plastic bags. Buyers also need to evaluate product certifications, packaging performance, supplier reliability, regulatory requirements, and long-term supply capability.
As packaging regulations continue to evolve, particularly under the EU Packaging and Packaging Waste Regulation (PPWR), choosing the right compostable packaging supplier has become a key procurement decision for zero waste retailers.
This guide explains what businesses should consider when sourcing compostable packaging and how to identify a reliable manufacturing partner.
Why Choosing the Right Supplier Matters
Many compostable bags on the market look similar, but product quality and compliance can vary significantly.
For zero waste stores, choosing the wrong supplier may result in:
* Products without recognized third-party certifications
* Inconsistent bag quality and sealing performance
* Limited production capacity for business growth
* Missing technical documentation required for export markets
* Increased procurement risks and customer complaints
Selecting an experienced compostable packaging manufacturer helps reduce these risks while supporting long-term business development.

What Zero Waste Stores Should Look For
Third-Party Certifications
Certification is one of the most important factors when evaluating compostable packaging.
Recognized certifications include:
* OK compost HOME
* OK compost INDUSTRIAL
* EN13432
* BPI ASTM D6400
* AS5810
* AS4736
These certifications demonstrate that products have been independently tested against recognized compostability standards.
Buyers should request certification documents rather than relying solely on marketing claims.
Manufacturing Capability
Consistent product quality depends on manufacturing capability.
An experienced supplier should have:
* Automated production lines
* Stable quality management systems
* Reliable production capacity
* Export experience in multiple international markets
These factors help ensure consistent product performance and stable long-term supply.

Regulatory Compliance
Packaging regulations continue to evolve worldwide.
For businesses supplying the European market, the Packaging and Packaging Waste Regulation (PPWR) introduces new requirements for certain packaging applications and strengthens documentation requirements throughout the supply chain.
Businesses should ensure their suppliers can provide technical documentation, certification records, and regulatory support for their target markets.

Product Performance
For zero waste stores, compostable packaging must perform reliably during everyday use.
Important considerations include:
* Load-bearing strength
* Seal integrity
* Storage stability
* Shelf life
* Compostability performance under appropriate composting conditions
Compostable packaging should deliver practical functionality before reaching its intended end-of-life.
It is also important to remember that **compostable bags are not recyclable products** and should be disposed of through appropriate composting systems according to local waste management practices.
