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.

Compost Pile Smells: A Diagnostic Chart by Odor
A healthy compost heap smells faintly of damp forest floor — earthy, slightly mushroomy, never offensive. Anything else is a diagnostic signal pointing at a specific imbalance. This piece walks through the smells you’ll actually encounter in a backyard or community heap, what each one says about what’s happening inside the pile, and the fix…

Composting in Cold Climates: Slow but Steady Wins
Cold-climate composting doesn’t fail because of the cold. It fails because the standard backyard playbook assumes a temperature range the pile never sees. The fix isn’t a heated tumbler or an indoor system; it’s a different mental model that accepts winter dormancy, plans for it, and builds a system that catches up in spring.

What’s Bagasse and Where Does It Come From?
Bagasse is the dry fibrous residue left over after sugarcane stalks are crushed for juice. For most of the past century it was burned as cheap fuel in sugar mills. In the last twenty years it has become one of the most widely used raw materials in compostable foodware. The supply chain runs through Brazil,…

What Is Finished Compost Supposed to Look Like?
Finished compost has a specific look, smell, and feel that doesn’t quite match the dramatic ‘rich black gold’ phrasing of gardening books. It’s dark brown, not black. It crumbles between your fingers but isn’t dust. It smells like forest floor after rain, never like the kitchen scraps you started with. Here’s the working description, the…

What’s the Best Compost Bin Size for a Family of Four?
A family of four generates between 1.5 and 2.5 cubic feet of compostable waste per week. Most off-the-shelf compost bins are sized for a couple, not a household, which is why so many family piles overflow by month four. The right answer depends on yard size and climate, but it almost always points at more…

Mardi Gras Beads: Compostable Alternatives Are Real
An average Mardi Gras season in New Orleans dumps 25 million pounds of plastic beads onto the streets. They clog storm drains, leach heavy metals into the soil, and contribute to one of the most concentrated single-event waste problems anywhere. Compostable alternatives have existed for several years now — algae-based, paper, seed, wood — and…

Mother’s Day Cards That Plant Themselves
Americans buy roughly 113 million Mother’s Day cards a year. Almost all of them end up in the recycling bin within a week, and a meaningful share end up in landfill instead because of foil, glitter, or plastic film. Plantable seed paper cards have been around since the 1990s but stayed a niche craft product…

Spring Picnics: Compostable Basket Liners
The picnic basket is having a small revival. Spring 2024 and 2025 saw a noticeable spike in basket sales, picnic-themed Instagram content, and park-permit picnic bookings. The basket itself has gone slightly upscale. The lining underneath the food, though, is still mostly the same cheap plastic mat or aluminum foil that ends up in the…

The Tea Bag Mountain That Inspired a Composting Revolution
For decades, British households dropped used tea bags into compost bins assuming the bag broke down with the leaves. Then a gardener noticed mesh skeletons surviving in his finished compost, and a quiet consumer revolt forced the UK’s biggest tea brands to rethink what they were sealing into millions of bags every day.

What’s EN 13432 and How Does It Differ From ASTM?
EN 13432 and ASTM D6400 are the two standards almost every compostable packaging product gets tested against. They look interchangeable on a spec sheet. They aren’t. The differences matter most when you ship across borders, work with multiple certifying bodies, or have to defend a compostability claim in front of a procurement officer who asks…

Retirement Parties: Compostable Cake Plate and Catering
Retirement parties have a specific tableware footprint — small cake plates, a punch service, hors d’oeuvres, maybe a sit-down dinner — that doesn’t quite match wedding-event guides or office-lunch buying patterns. Here’s a working playbook for picking compostable plates, forks, cups, and napkins for the retirement-party shape, with quantity math and the mistakes that consistently…

6 Compostable Materials Compared by Carbon Footprint
Compostable materials produce different carbon footprints across their lifecycles. PLA, bagasse, paper, bamboo, hemp, and others have distinct production energy, transportation impact, decomposition profile, and overall lifecycle carbon. Understanding the comparison helps buyers and operators select materials that fit their priorities. Here’s the practical comparison across six common compostable materials.
