8 Gallon Compostable Trash Bags (30L Compostable Bin Liners)
8 gallon compostable trash bags—also commonly specified as 30L compostable bin liners—are designed for small kitchen bins and indoor organics collection systems.
These compostable liners are widely used in commercial kitchens, cafés, offices, schools, and institutional facilities where reliable compostable bags are required for daily food waste disposal.
Our 8 gallon compostable trash bags / 30L compostable bin liners are manufactured exclusively for B2B procurement, supporting distributors, waste-management programs, and facility operators requiring stable bulk supply and consistent product specifications.
As a factory-direct manufacturer, we provide OEM and private-label production with customizable bag dimensions, thickness options, seal structures, and packaging configurations.
What Are 8 Gallon Compostable Trash Bags?
8 gallon compostable trash bags are small-capacity compostable liners designed to fit indoor bins used for food waste and organic waste collection.
In Australia and many international markets, this capacity is commonly described as 30L compostable bin liners.
These liners are typically used in locations close to the waste source, including:
- kitchen food-waste bins
- office pantry bins
- café and restaurant prep areas
- indoor compost collection stations
Compared with larger sizes such as 60L or 120L compostable bin liners, 8 gallon liners are replaced more frequently and require reliable tear resistance and leak control for daily operations.
Typical Applications for 8 Gallon / 30L Bin Liners
8 gallon compostable trash bags are commonly used in:
- commercial kitchens and food preparation areas
- cafés, restaurants, and catering facilities
- office kitchens and staff break rooms
- hospitals, schools, and childcare centres
- supermarkets and food retail back-of-house waste stations
In these environments, liners must perform reliably with wet organic waste, frequent handling, and regular bag changes.
AS4736 & AS5810 Certified Compostable Materials
All compostable bin liners supplied by ORIZON are manufactured using certified compostable plant-based materials.
Our materials typically consist of PLA / PBAT blends, designed to achieve the balance between durability and compostability required for professional waste management systems.
Available certifications include:
- AS4736 – Industrial Compostable
- AS5810 – Home Compostable
- EN13432 – EU Industrial Compostable
- ASTM D6400 – US Compostable Standard
These materials break down in certified composting environments without leaving microplastics or harmful residues.

Trash Bag Capacity Conversion
Different regions describe waste bag capacity using either gallons or litres.
| Trash Bag Size | Equivalent Capacity | Typical Use |
|---|---|---|
| 8 gallon | ≈ 30 L | small kitchen bins |
| 13 gallon | ≈ 50 L | standard kitchen bins |
| 30 gallon | ≈ 114 L | commercial waste |
| 33 gallon | ≈ 125 L | contractor bags |
For this reason, 8 gallon compostable trash bags are frequently referred to as 30L compostable bin liners in Australia and Europe.
Available Specifications for 8 Gallon Bin Liners
For professional procurement, bin liner specifications must match the application environment.
Typical specifications include:
| Specification | Details |
|---|---|
| Capacity | 8 gallon / 30 L |
| Material | PLA + PBAT compostable blend |
| Thickness | customizable for application |
| Seal type | star seal or flat seal |
| Packaging | rolls or bulk cartons |
| Certification | AS4736 / AS5810 / EN13432 / ASTM D6400 |
Exact bag dimensions (flat width × length) can be adjusted according to bin design and waste profile.
Thickness Selection for 30L Compostable Bin Liners
Selecting the correct liner thickness is essential to balance durability, compostability, and cost efficiency.
Thickness selection plays a critical role in balancing performance, cost efficiency, and compostability.
Typical guidance includes:
- Light food waste (dry scraps, coffee grounds):
Lower thickness options suitable for frequent bag changes - Wet organics (food waste with liquid content):
Medium thickness options to reduce leakage and tearing - High-turnover commercial use (kitchens, institutions):
Reinforced thickness for improved handling strength and reduced failure rates
Rather than over-specifying thickness, we help buyers select application-appropriate specifications that minimise complaints while controlling procurement costs.
Seal Structures and Bag Design Options
The bottom seal structure plays an important role in load distribution and leak resistance.
Common seal types include:
Star seal (star gusset)
Even load distribution and improved leak resistance
Recommended for wet food waste applications
Flat seal
Suitable for controlled waste streams with lighter loads
Additional customization options include:
- flat opening or vest-style opening
- customized bag dimensions
- different roll configurations
- bulk carton packaging
Performance for Food Waste & Daily Indoor Use
Our 30L compostable waste bags are designed for real operating conditions—not laboratory demonstrations.
Key performance features include:
- Tear resistance during frequent bag changes
- Moisture resistance for wet food waste
- Reliable sealing to minimise leaks and odours
- Consistent quality across bulk production batches
This makes them suitable for high-turnover indoor organics programs.
