Buying Guide

Check compostability certifications

Look for third-party certifications such as BPI or OK Compost Industrial/Home to ensure bags break down appropriately in commercial or home compost systems

Match bag size to your use

Choose small 2–3 gallon liners for countertop food waste, 13‑gallon bags for kitchen bins, and 33‑gallon or 87L bags for yard waste to avoid over- or under-sizing

Consider material strength and seam quality

Thicker compostable formulations and reinforced seams reduce tearing when handling wet or heavy food scraps and yard debris

Compare count and cost-per-bag

Evaluate pack counts (e.g., multi-packs of 50–100 bags) to determine the per-bag value rather than only the overall pack price

Verify intended compost environment

Some bags are rated for industrial composting while others are OK Compost Home certified—match the rating to whether you use curbside/municipal composting or a home system
