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.

Glass Containers: How They Work Inside a Compostable-First Kitchen
A ‘compostable-first’ kitchen isn’t a kitchen full of compostable disposables. It’s a kitchen where the default for any one-time use is compostable, and where the default for repeated use is reusable — typically glass, sometimes stainless steel, sometimes silicone. Glass plays a specific role in this approach: it handles the food-storage, leftovers, and reusable-container categories…

A Buyer’s Guide to Compostable Cone Filters
Coffee cone filters are one of the smallest disposable items in a coffee-drinking household, used 1-3 times per day, tossed into compost or trash with the spent grounds. The compostability question turns out to be more nuanced than most coffee drinkers assume — bleaching processes, fiber sources, manufacturing certifications, and what ‘compostable’ actually means for…

The Basics of TÜV OK Compost Certification Tiers
TÜV Austria’s OK Compost certification family is the most widely-recognized European compostability mark, and the structure has more layers than most buyers realize. OK Compost INDUSTRIAL, OK Compost HOME, OK Bio-Based, OK Soil Biodegradable, OK Marine Biodegradable, and several others each test different end-of-life conditions or different attributes. Knowing which mark on a package actually…

Kid Birthday Goodie Bags: Compostable Treat Containers
Goodie bags are one of the quietly more wasteful corners of kid birthday culture. The standard format — a cellophane bag filled with a handful of cheap plastic toys, individually-wrapped candy, and themed stickers — produces a disposable disposable. The cellophane bag itself goes in the trash within 48 hours. Most of the toys are…

Wedding Reception Cup and Plate Strategy
A wedding reception puts more pressure on disposable tableware than almost any other event. The plates and cups have to hold up to professional photography, scrutinize at close range by hundreds of guests, complement venue aesthetics, and survive a 4-6 hour event with multiple courses. The compostable options have matured enough to handle the demand,…

9 Best Compostable Plates for Outdoor Events
Outdoor events stress disposable plates in ways indoor events don’t. Wind blows lightweight plates off tables. Sun softens flimsy materials. Hot food and barbecue grease test grease resistance. Stacked storage in coolers demands rigid nesting. The compostable plate category has matured to handle outdoor demands across nine distinct products that each fit specific use cases.…

Compostable Library Cards: A Real Pilot Program
The plastic library card has been a quietly-overlooked piece of municipal disposable infrastructure for decades. Public library systems issue them by the millions, then re-issue replacements when cards are lost, replace whole batches when card designs change, and never recover them when patrons move away. Compostable card pilots have emerged in adjacent categories — hotel…

The Basics of Carbon Sequestration in Foodservice
Carbon sequestration in foodservice is one of the more confused topics in restaurant sustainability. The phrase gets used to mean different things — sometimes carbon avoidance, sometimes carbon offsetting, sometimes literal soil carbon storage from regenerative sourcing. Understanding the distinction matters because some forms of sequestration are real and durable while others are essentially marketing…

Fall Leaves: The Free Compost Treasure Most People Throw Away
Every American household with mature trees produces somewhere between 50 and 300 pounds of fallen leaves each autumn. The standard ritual is to rake them, bag them, and put them at the curb for collection. Some go to municipal composting; many more go to landfill. Almost none are kept on-site for the household’s own use,…

The PHA Bacteria That Eat Their Own Plastic Discovery
In 1925, a French chemist named Maurice Lemoigne noticed that certain bacteria stored carbon energy as small granules of a plastic-like polymer inside their cell bodies. The same bacteria, when food ran out, would break the polymer back down and consume it. The discovery sat largely ignored for fifty years before becoming the basis for…

The Edible Compostable Cup That Tastes Like a Cookie
Edible coffee cups have moved from novelty trial to genuine commercial product over the past decade. Air New Zealand serves them on flights. Bulgarian company Cupffee ships them to coffee shops across Europe. KFC ran a UK pilot in 2015. The cup is a wafer-style cookie that holds hot or cold liquid for an hour,…
