What Makes a Bag Compostable?
Material Composition
Unlike conventional plastics derived from fossil fuels, compostable bags are manufactured from renewable plant-based materials including:
- Corn starch: Provides structural integrity and flexibility
- Tapioca: Enhances biodegradation rates
- PLA (Polylactic Acid): Derived from fermented plant sugars
- PBAT: Biodegradable polymer for durability
These materials undergo sophisticated processing to create films that match or exceed the performance of conventional plastics while maintaining complete biodegradability under appropriate composting conditions.
Certification Standards
Legitimate compostable products must meet internationally recognized certification standards. In Australia and New Zealand, the Australasian Bioplastics Association (ABA) administers verification programs including:
- AS4736-2006: Australian Standard for compostable plastics
- OK Compost: European certification (EN 13432)
- OK Biobased: Verification of renewable material content
- Seedling Logo: Visual certification for consumer recognition
Because We Care maintains all relevant certifications, with products verified by the Australian Government National Measurement Institute for ongoing compliance.
Types of Compostable Bags
Bin Liners
Compostable bin liners provide an essential service for organic waste diversion. When food scraps and garden waste are placed in compostable liners, the entire package can be processed at commercial composting facilities without separating the bag from its contents. This simplifies waste handling for households, restaurants, and commercial kitchens while ensuring organic material reaches appropriate processing facilities.
Available in various sizes from small kitchen caddy liners to large commercial waste bags, compostable bin liners offer the leak resistance and strength necessary for practical use while breaking down completely within 90-180 days in industrial composting conditions.
Dog Waste Bags
Pet ownership creates significant waste management challenges, with conventional plastic dog bags persisting in landfills for centuries. Compostable dog waste bags offer a responsible alternative, allowing pet owners to manage waste without contributing to long-term plastic pollution.
Produce Bags
Retailers transitioning from single-use plastic produce bags to compostable alternatives support customers in reducing overall plastic consumption. These lightweight bags protect fresh produce while offering end-of-life options through home or commercial composting.
Retail and Shopping Bags
With single-use plastic bag bans expanding across Australian jurisdictions, businesses require compliant alternatives. Compostable shopping bags provide the carrying capacity and durability customers expect while meeting regulatory requirements. Custom printing options allow businesses to maintain brand visibility while demonstrating environmental responsibility.
Benefits for Businesses
Regulatory Compliance
Australian states and territories continue implementing single-use plastic restrictions. Businesses adopting compostable alternatives position themselves ahead of regulatory requirements, avoiding potential penalties and supply disruptions as legislation evolves.
Brand Differentiation
Consumers increasingly factor environmental considerations into purchasing decisions. Businesses offering compostable packaging communicate values alignment with environmentally conscious customers, creating competitive differentiation.
Waste Management Efficiency
Organizations implementing organic waste diversion programs benefit from compostable packaging that simplifies waste streams. Food service operations can collect food scraps in compostable containers without separating packaging from contents.
Supply Chain Resilience
Plant-based materials offer supply chain advantages over petroleum-dependent alternatives. Agricultural feedstocks provide renewable sourcing, while domestic production reduces international shipping dependencies.
Proper Disposal and Composting
Industrial Composting
Compostable bags achieve optimal degradation in controlled industrial composting environments where temperature, moisture, and microbial activity are carefully managed. Commercial facilities maintain conditions that break down compostable materials within 90-180 days.
Home Composting
Some compostable products are certified for home composting, though degradation occurs more slowly due to lower and more variable temperatures. Home composters should verify specific product certifications.
Waste Collection Services
Many Australian councils now provide FOGO (Food Organics and Garden Organics) collection services accepting compostable packaging. Businesses and residents should confirm local council capabilities.
Conclusion
Compostable bags offer businesses a practical pathway toward sustainable packaging without sacrificing performance or convenience.

Environmental Impact and Sustainability
Reducing Plastic Pollution
Conventional plastic bags contribute significantly to environmental degradation, persisting in landfills for hundreds of years and creating microplastic contamination throughout ecosystems. Compostable alternatives eliminate this long-term pollution burden, breaking down into harmless organic compounds that enrich soil rather than contaminating it.
Carbon Footprint Reduction
Plant-based materials sequester carbon during growth, partially offsetting emissions from production and transportation. Life cycle assessments demonstrate significantly lower carbon footprints for compostable packaging compared to petroleum-based alternatives, supporting corporate sustainability goals and climate commitments.
Circular Economy Integration
Compostable packaging enables true circular economy pathways where packaging materials return to the soil as valuable compost, supporting agricultural productivity and closing the loop between consumption and production. This contrasts with linear plastic systems that end in landfill or incineration.
