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.

A Buyer’s Guide to Compostable Espresso Pods
Single-serve coffee pods are one of the worst single-use packaging categories by volume — somewhere around 56 billion pods produced globally each year, with roughly 95% non-compostable in 2022. Compostable alternatives have improved enough that several work in standard Nespresso and Keurig machines without modification, taste reasonably comparable to conventional pods, and break down in…

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…

Birthday Decorations Without Latex Balloons: 5 Alternatives
Latex balloons get marketed as ‘biodegradable’ and most party hosts assume that means harmless. The reality is balloons take years to break down, regularly end up in wildlife stomachs, and contribute to a steady stream of plastic-and-rubber waste from celebrations that don’t actually need balloons to feel celebratory. Five alternatives produce the same visual lift…

8 Compostable Items in Your Kitchen You’re Probably Throwing Away
Most households compost food scraps and yard waste and stop there. The rest of the kitchen produces a steady stream of items that go in the trash bin out of habit but compost just as well — coffee filters, paper towels, wine corks, wooden skewers, hair from the bathroom sink. Adding these eight items to…

Can I Compost Cooking Oil?
The short answer is mostly no — and the longer answer explains why even small amounts of cooking oil disrupt a backyard compost pile, where industrial facilities draw the line, and what to actually do with the gallon of used fryer oil sitting in your kitchen. Cooking oil disposal is one of the household-waste questions…

The Reusable Produce Bag Setup That Travels Through TSA
Most reusable produce bag setups are built for grocery shopping. The same bags are surprisingly useful for travel — packing snacks, separating contents, organizing carry-ons — if you pick the right materials and know which fabrics confuse airport scanners. Here’s the working four-or-five-bag kit that handles produce shopping at home, breezes through TSA when traveling,…

What’s ASTM D6400 and Why Should I Care?
ASTM D6400 is the US standard that almost every state law, every FTC compostability claim, and every BPI certification ultimately rests on. It looks like a dry technical specification, but the way it’s written and enforced shapes what ‘compostable’ actually means on a product label, what gets accepted at industrial composting facilities, and what gets…

The Basics of Industrial Composting Facilities
An industrial composting facility is the working backbone of every claim that something is ‘compostable in industrial conditions.’ These facilities process millions of tons of organic waste annually across the US, run at temperatures hot enough to break down materials a backyard pile can’t, and produce graded compost that goes to farms, landscaping, and erosion…

Christmas Tree Composting: From Living Room to Garden Mulch
Roughly 25-30 million live Christmas trees enter American living rooms each December. About a third of them go to landfill in early January. The rest get curbside-collected, dropped at municipal recycling programs, or processed by motivated households into firewood, mulch, garden stakes, and compost. The household processing path produces the most useful end products if…

5 Best Compostable Pizza Boxes That Don’t Leak Grease
Pizza boxes are one of the harder problems in compostable foodservice. The grease has to stay in. The cardboard has to compost. The cost has to compete with conventional. For years the industry’s answer was PFAS — the same chemicals now being banned across multiple US states. The post-PFAS pizza box landscape is still settling,…

A Buyer’s Guide to Compostable Plates for Birthday Parties
A birthday party tableware order has a different shape than a wedding, a corporate event, or an everyday takeout meal. The food mix is sugary, the portions are small but messy, the kids are enthusiastic about spillage, and the host has to balance themed aesthetics against the reality of frosting bleed. This is the working…
