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.

Composting Fish Scraps Without Attracting Pests: A Practical Guide
Most composting guidance flatly forbids fish scraps because of pest attraction — raccoons, rats, flies, dogs, neighborhood cats. The standard advice ignores that fish scraps are nutrient-dense compost material that humans have been processing for centuries. The real question is not whether to compost fish but how to do it safely. This guide covers the…

A 1950s Magazine Article That Predicted Compostable Plastic — Did One Actually Exist?
The idea of compostable plastic feels modern, but the conceptual seeds were planted decades earlier. Did a 1950s magazine article predict compostable plastic specifically? The honest answer is that mid-century plastic futurism was vast and varied, and definitive single-article claims are hard to verify. What is documentable is a richer story: the 1950s thinking about…

The Squirrel That Built a Nest of Compostable Bowl Fragments — Wildlife and Bioplastic in the Real World
The story of a squirrel using compostable bowl fragments in its nest is the kind of anecdote that captures how compostable packaging behaves once it enters the natural environment rather than the industrial composting facility it was designed for. Whether or not a specific squirrel has been documented doing this exactly, the broader phenomenon is…

The First Compostable Cup at the Olympics (And Where It Was): What We Actually Know
Which Olympics first served beverages in compostable cups? The honest answer is that no clear documented record establishes a definitive first. What we do have is a multi-Games history of sustainability programs that progressively normalized compostable packaging — Vancouver 2010, London 2012, Sochi 2014, Rio 2016, PyeongChang 2018, Tokyo 2020, Beijing 2022, and Paris 2024…

How to Recycle Your Old Plastic Toothbrush Heads (Without Just Tossing Them in the Bin)
A used toothbrush head looks small but the global toothbrush waste stream is enormous — billions of toothbrushes discarded annually, almost all of them ending up in landfill or ocean. This guide covers what your toothbrush is actually made of, why it doesn’t go in normal recycling, the take-back programs that do work, the genuine…

What Plants Don’t Like Compost? A Gardener’s Guide to the Exceptions
Compost is the universal soil amendment of home gardening — until it isn’t. Some plants, by evolutionary design, thrive in lean, mineral, dry, or acidic soils where rich compost actually hurts performance. Cacti, Mediterranean herbs, native wildflowers, alpines, blueberries, and several other categories underperform in compost-amended soil. This guide walks through which plants prefer lean…

How Much Compost Does One Household Produce a Year? A Realistic Estimate
A four-person household typically generates 600 to 1,200 pounds of compostable kitchen and yard waste per year, which yields roughly 200 to 400 pounds (4 to 8 cubic feet) of finished compost. The numbers vary widely with household size, eating habits, yard size, climate, and composting method. This guide walks through the realistic numbers, what…

The Basics of Bioplastic Chemistry: PLA, PHA, PBAT, and the Family Tree of Compostable Polymers
Compostable plastics share a name but not a chemistry. PLA is made from corn or sugarcane, behaves like rigid plastic, and composts in industrial systems. PHA is produced by bacteria, breaks down in marine environments, and costs much more. PBAT is petroleum-based but biodegradable, and is usually blended with starch or PLA to make compostable…

How to Handle Rush Orders on Compostable Packaging
Compostable packaging supply chains are tighter than conventional ones. Custom print lead times run weeks. Manufacturing capacity is concentrated. Stock SKUs cycle through distributor inventories more variably. When a venue, restaurant, or chain needs significant volume on short timeline, the situation requires structured response — supplier qualification, substitution protocols, freight tactics, and clear communication. This…

How to Manage Compostable Packaging Storage and Shelf Life
Compostable packaging is built to break down. That same property makes it more sensitive to storage conditions than conventional plastic. Humidity, temperature, light exposure, and stack pressure all affect shelf life. This guide covers the storage practices, environmental controls, inventory rotation, and quality monitoring that protect a compostable inventory through its useful life.

The Basics of Microplastic Contamination: Sources, Pathways, and the Compostable Connection
Microplastics are now found in human blood, breast milk, placentas, lung tissue, drinking water, agricultural soil, atmospheric dust, and the deepest ocean trenches. The contamination is comprehensive and the trajectory is increasing. This is a foundational guide to what microplastics are, where they come from, how they move through ecosystems and human bodies, the emerging…

Memorial Trees: From Planting to Compost-Loop Closure
A memorial tree is one of the longest-running rituals a household can undertake. Plant it well and it grows for decades. Maintain it thoughtfully and every fall’s leaf drop returns to the soil that feeds the next year’s growth. Eventually, generations later, the tree itself returns to compost. This is a practical guide to memorial…
