UNNI Compostable Trash Bags 23 Gallon Value Pack - Certified Home

Our review of the UNNI Compostable Trash Bags focuses on households and small facilities that collect daily food scraps and want a certified, plant-based liner. The biggest reason to consider these bags is their blend of proven compostability and everyday practicality: two rolls of 30 liners (60 total) sized for 23 gallon / 87 liter cans, with independent certifications that confirm they break down in home and commercial systems. For anyone prioritizing reducing conventional plastic while keeping a tidy large-capacity bin, these are a practical option.

Key Features

• Bulk value pack: Two rolls of 30 bags provide 60 liners, which reduces the frequency of repurchase and is convenient for busy kitchens and offices.
• Large capacity: The 23 gallon / 87 liter size (28 in x 42 in) fits common 20-23 gallon bins and helps contain daily food scraps without constant bag changes.
• Reinforced thickness: At roughly 1.0 mil thickness, the liners handle typical kitchen peels, pulp and food scraps with less immediate tearing than very thin compost bags.
• Certified compostable: Independently certified by BPI, CMA and OK compost HOME to meet ASTM D6400, so the bags are validated for home and industrial composting systems where accepted.
• Plant-based materials: Made from plant-derived polymers to cut reliance on conventional plastic while still functioning as practical bin liners.
• Storage guidance: The manufacturer recommends storing in a cool, dry place and using within 12 months for best performance to retain strength and compostability.

Who It's For

These liners are best for environmentally minded households, small cafeterias, schools, and offices that collect food scraps in larger 20-23 gallon cans and want certified compostable options. The pack size and size make them useful where frequent changes are needed and bulk savings matter.

Those who rely on very wet or heavy waste streams, or who need industrial-strength contractor bags, should look elsewhere; pro composting facilities and heavy-duty municipal collection may require thicker or specifically engineered commercial bags. Also check local composting availability since commercial composting is not universal.

Pros & Cons

Pros

• Certified by BPI, CMA and OK compost HOME, so compostability is independently validated.
• Large 23 gallon size and 60-count bulk pack reduce shopping frequency and fit common kitchen cans.
• Plant-based construction reduces reliance on fossil-fuel plastics while remaining functional as a liner.
• Reinforced 1.0 mil thickness provides reasonable durability for daily food-scrap use.

Cons

• Some users report mixed durability with occasional tearing or leakage when handling very wet scraps, so extra care or lining with paper is advised.
• Composting infrastructure varies by location, so certified composting may not be available everywhere.
