Compostable Packaging Resources & Guides
Welcome to the Pure Compostables resource library — a working set of in-depth guides written for the people who actually procure, evaluate, and switch to compostable packaging. You’ll find detailed certification breakdowns (BPI, TUV, EN 13432, ASTM D6400 and beyond), step-by-step playbooks for transitioning a business away from conventional plastics, and product selection guides covering bag sizes, materials, and use cases. Every article is written from the perspective of a manufacturer with thirteen years of operating experience — not a marketing team. Use the categories below to navigate by topic, or browse the most recent guides directly. If your question isn’t answered here, our team is happy to help — start with our wholesale page or send us a note via the contact page.

The Basics of Bagasse and Plant Fiber Materials
Bagasse — the fibrous residue from sugarcane processing — is the largest single material used in compostable foodware today. Combined with other plant fibers (bamboo, wheat straw, palm leaf, banana fiber), it forms a category that has displaced billions of polystyrene plates and bowls. Here’s how it actually works.
