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 ESG Reporting for Foodservice Brands

    ESG reporting — Environmental, Social, and Governance disclosure — has shifted from optional voluntary practice to expected business communication for foodservice brands. Major customers (Sysco, US Foods, large hotel chains, corporate dining contracts) increasingly require ESG documentation as procurement condition. Investors expect it. Regulators in multiple jurisdictions now mandate disclosure for certain operation sizes. The…

  • The Basics of B Corp Certification for Foodware Companies

    B Corp Certification is the comprehensive sustainability and social impact certification administered by B Lab. For foodware companies — manufacturers, distributors, brands — B Corp Certification signals verified commitment to environmental and social practices that goes beyond marketing claims. The certification requires meeting performance standards across five categories, legal accountability via corporate bylaws, and ongoing…

  • A Compostable Bird Feeder Made From Sunflower Seeds

    A compostable bird feeder made entirely from sunflower seeds is a real and documented DIY project. Compressed sunflower seed cakes — sometimes with peanut butter or honey as binder — work as both food source and the feeder itself. Birds eat the seeds; the remaining structure eventually breaks down and composts. The feeder lasts 1-3…

  • The pH of Healthy Compost: How to Test and Adjust

    Healthy finished compost has a pH between 6.0 and 8.0, with the sweet spot around 6.5-7.5. Active compost piles drift through different pH ranges during decomposition — initial pH around 4-5 from organic acid release, climbing through neutral as microbial activity proceeds, finishing at slightly alkaline. Testing pH at different stages reveals whether the pile…

  • Birthday Cake Candles: Compostable Wax and Reused Holders

    Birthday cake candles are a small annual waste category that’s easy to improve. The conventional birthday candle is paraffin wax (petroleum-derived) with a plastic spike for cake insertion. After one use it goes to trash. Beeswax and soy wax candles offer compostable alternatives. Reusable metal or wooden candle holders eliminate single-use plastic. The combined approach…

  • A Pandemic Compostable Item: The PPE Made From Plant Fiber

    During the 2020-2022 pandemic, the global use of disposable personal protective equipment (PPE) exploded. Surgical masks, face shields, gloves, and gowns generated an estimated 3.4 billion individual items per day at the peak. Most was made from synthetic plastics — polypropylene, polyethylene, nitrile rubber — that persist for centuries in landfills. Some researchers and companies…

  • The University Cafeteria That Reduced Trash by 80 Percent

    The claim of a university cafeteria reducing trash by 80 percent is plausible and matches achievements documented at several actual university dining programs. The University of California campuses, Middlebury College, Oberlin College, Stanford, Cornell, and similar institutions have all published sustainability reports showing 70-95% waste diversion through comprehensive programs. The 80% figure is consistent with…

  • Wedding Cocktail Hour: Compostable Stirrers and Picks

    Wedding cocktail hours generate substantial small-item bar waste — stirrers, picks for olives and citrus garnishes, paper drink napkins, sometimes paper straws. A 150-guest wedding typically uses 300-600 stirrers and picks across cocktail hour and reception. Conventional plastic versions go to landfill within hours. Compostable alternatives — wooden stirrers, bamboo picks, paper straws, natural fiber…

  • How to Set Up a Composting Program at an Office

    Office composting programs differ from restaurants, stadiums, and schools in operational scale and worker engagement. A typical 200-person office generates 5-12 lbs of compostable waste daily, mostly from coffee grounds, lunch leftovers, and pantry waste. Programs work best when integrated with existing facilities management, when properly sized for actual volumes, and when employees develop simple…

  • 7 Compostable Cup Lid Designs Compared

    Compostable cup lids come in seven main design categories: flat sip lid, dome cold lid, dome hot lid, flat cold lid with straw slot, vented hot lid, sippy cup style, and specialty designs. Each design targets specific cup applications and beverage types. The compostability characteristics vary by material (PLA, CPLA, paper, bagasse) and certification (BPI,…

  • 9 Compostable Items Every Sushi Restaurant Needs

    Sushi restaurants have a particular foodware mix — small dishes, soy sauce containers, wasabi cups, chopsticks, takeout boxes, condiment cups, paper sleeves for chopsticks, and napkins. The conventional version uses substantial single-use plastic. Compostable alternatives exist for all nine categories, and the cost premium is modest for most. A typical 60-seat sushi restaurant going compostable…

  • 9 Reasons Composting Improves Soil Health

    Compost applied to garden soil produces nine documented improvements: it adds slow-release nutrients, increases organic matter content, improves soil structure, enhances water retention, supports microbial diversity, reduces fertilizer needs, sequesters carbon, suppresses plant diseases, and buffers pH variation. The improvements aren’t just gardening folklore — agricultural research at land-grant universities has documented each effect across…
