Why Switch to Compostable Bin Liners: Environmental Benefits Explained
Understanding What Makes a Liner Truly Compostable
Truly compostable liners are made from plant-based materials like cornstarch, vegetable oils, and PLA (polylactic acid) that break down completely in composting conditions. Unlike “biodegradable” plastics that may leave microplastic residue, certified compostable liners decompose into water, carbon dioxide, and biomass within 180 days in commercial composting facilities. Look for certification labels like ASTM D6400, EN13432, or BPI to ensure your liners meet strict decomposition standards.
How Compostable Liners Reduce Your Carbon Footprint
Switching to compostable bin liners significantly reduces your carbon footprint by decreasing reliance on petroleum-based plastics that release greenhouse gases during production and disposal. When compostable liners break down, they return nutrients to the soil instead of releasing methane in landfills. Research shows that plant-based liners produce up to 70% fewer carbon emissions in their lifecycle compared to conventional plastic bags, particularly when composted properly with food waste.

Frequently Asked Questions
What are compostable bin liners made of?
Compostable bin liners are made from plant-based materials such as cornstarch, PLA (polylactic acid), vegetable oils, and sugar cane. Unlike traditional plastic bags, these materials are designed to break down completely in composting environments without leaving harmful residues. Some brands like Repurpose use a triple-layer construction of various plant-based components, while others like UNNI incorporate cornstarch and PBAT for durability.
How long do compostable bin liners take to decompose?
Certified compostable bin liners typically break down within 180 days in commercial composting facilities. Some high-performance options like Repurpose bags can decompose in 90-180 days. Home composting may take longer, depending on conditions. This decomposition timeframe is significantly faster than conventional plastics, which can persist for hundreds of years in the environment.
Are compostable bags as durable as regular plastic bags?
Yes, many compostable bags offer comparable durability to regular plastic bags. Premium options like BioBag and UNNI (with 0.85 MIL thickness) can effectively handle wet organic waste without leaking or tearing. Brands like EcoSafe and Stout by Envision feature reinforced seams that can support up to 25 pounds of waste. The multi-layer construction in many compostable bags provides excellent moisture resistance.
What’s the difference between biodegradable and compostable bags?
Compostable bags break down completely into non-toxic components (water, carbon dioxide, and biomass) within a specific timeframe, typically 180 days in commercial facilities. Biodegradable bags may eventually break down but can leave behind microplastics and harmful residues. True compostable bags are certified by organizations like the Biodegradable Products Institute (BPI) and meet ASTM D6400 standards, ensuring complete decomposition.
Can compostable bin liners go in home compost piles?
Most certified compostable bin liners are designed for commercial composting facilities, which maintain higher temperatures necessary for complete breakdown. Some brands like Repurpose claim their bags can break down in home composting setups under optimal conditions. However, home composting may take longer and be less effective at completely breaking down the liners compared to industrial facilities.
How do compostable bin liners reduce carbon footprint?
Compostable bin liners reduce carbon footprint by minimizing reliance on petroleum-based plastics and returning nutrients to the soil. Research indicates they produce up to 70% fewer carbon emissions over their lifecycle when properly composted. By diverting organic waste from landfills (where it produces methane) to composting facilities, these liners contribute to a circular economy approach to waste management.
Which size compostable bin liner should I choose?
Choose a compostable bin liner size that matches your specific container. Brands like BioBag and EcoSafe offer multiple sizes ranging from small 3-gallon kitchen counter bins to large 42-gallon commercial containers. For kitchen food waste, 3-gallon bags typically work well. For larger household or commercial needs, 13-30 gallon options are available. Always measure your bin before purchasing to ensure a proper fit.
How should I store compostable bin liners?
Store compostable bin liners in a cool, dry place away from direct sunlight and humidity. Unlike conventional plastic, compostable materials can begin breaking down if exposed to excessive moisture or heat. Keeping them in their original packaging until needed helps maintain their integrity. Some manufacturers recommend using the bags within 1-2 years of purchase for optimal performance.
