Food waste needs more than an ordinary bin bag
Food waste is different from ordinary dry rubbish.
For cafés, restaurants, commercial kitchens and NSW FOGO setups, choosing the right compostable food waste bin liner is different from choosing an ordinary rubbish bag.
It can be wet, heavy, uneven and sometimes include sharper or more acidic food scraps. A liner used for food scraps may need to handle coffee grounds, fruit peel, vegetable scraps, cooked food, sauces, leftovers and back-of-house kitchen waste.
This is why businesses should not choose compostable bin liners only by looking at whether a product is labelled “eco” or “compostable”. For food waste collection, the liner also needs to match the bin size, waste type and handling method.
Compostar’s wholesale compostable film liner range is designed to support this practical side of food waste collection.
Compostar wholesale compostable film liner range
Compostar’s current wholesale compostable film liner range covers 18L, 36L, 80L, 120L and 240L sizes.
This range is designed to support different food waste collection points across a business, from small caddies and café counters to back-of-house kitchen bins, wheelie bins and larger waste room setups.
The 18L liner is positioned for food waste caddies, small kitchen bins, café counters and office kitchens. The 36L liner supports small commercial food waste stations. The 80L liner is better suited to wet food waste and back-of-house kitchen use. The 120L and 240L liners support larger wheelie bin and FOGO collection points.
| Compostar Size | Compostar Thickness | Best Suited For |
|---|---|---|
| 18L | 20 micron | Food waste caddies, café counters, office kitchens, small food waste stations |
| 36L | 24 micron | Small commercial bins, staff kitchens, café prep stations, school food waste points |
| 80L | 26 micron | Commercial kitchens, wet food waste, back-of-house food waste collection |
| 120L | 26 micron | Wheelie bins, FOGO bins, food waste transfer, larger kitchen waste points |
| 240L | 26 micron | Large wheelie bins, hotels, clubs, schools, venues and waste rooms |
How Compostar compares with common compostable liner thickness ranges
Many compostable bin liners on the market do not clearly show thickness information, especially for larger food waste and wheelie bin applications.
Where thickness is publicly listed, small compostable caddy liners are often much thinner than commercial food waste liners. This can be acceptable for light scraps, but it may not be enough for wetter and heavier food waste.
| Size / Use Case | Common Thickness Range Seen in Public Product Listings | Compostar Thickness | What This Means |
|---|---|---|---|
| Small caddy / kitchen food waste liners | Around 12–20 micron | 18L: 20 micron | Compostar’s 18L liner sits at the stronger end of common small compostable liner ranges. |
| 30L–36L small commercial liners | Around 18–25 micron | 36L: 24 micron | Compostar’s 36L liner sits near the upper end of common small commercial compostable liner ranges. |
| 80L commercial kitchen liners | Often not clearly disclosed; commercial wet waste usually needs stronger liners | 80L: 26 micron | Compostar’s 80L liner is positioned for heavier food waste and back-of-house kitchen use. |
| 120L wheelie bin liners | Some publicly listed compostable liner products appear in lower thickness ranges | 120L: 26 micron | Compostar’s 120L liner provides a stronger thickness specification for wheelie bin and FOGO use. |
| 240L large wheelie bin liners | Some publicly listed compostable liner products appear in lower thickness ranges | 240L: 26 micron | Compostar’s 240L liner is positioned for larger wheelie bin use and high-volume food waste collection points. |

Why size matching matters
A liner that works well in a small food waste caddy may not work well in a large wheelie bin.
For small food waste caddies, the 18L liner can support café counters, office kitchens and staff kitchens. For shared food waste points, the 36L liner gives businesses another small-to-medium option.
For commercial kitchens, the 80L liner becomes the main back-of-house option in the wholesale range. It is better suited to wet food waste, prep-area scraps, heavier kitchen waste and hospitality bin setups than smaller caddy-style liners.
For larger movement of food waste, the 120L liner supports wheelie bins, FOGO bins and transfer points. For high-volume sites such as hotels, clubs, schools, venues and larger waste rooms, the 240L liner provides a larger wheelie bin option.
| Business Area | Recommended Compostar Size | Why It Fits |
|---|---|---|
| Café counter | 18L or 36L | Suitable for coffee grounds, tea leaves and small food scraps |
| Office kitchen | 18L or 36L | Good for daily food waste collection in staff kitchens and shared spaces |
| School food waste station | 36L or 80L | Suitable for shared food waste points and higher-volume collection |
| Commercial kitchen prep area | 80L | Better for wetter and heavier kitchen scraps |
| Restaurant back-of-house | 80L or 120L | Suitable for larger food waste movement and transfer points |
| Hotel, club or venue waste room | 120L or 240L | Better for larger wheelie bins and high-volume collection |

A practical lesson from food waste setup
Many food waste problems are not caused by one single product failure. They often come from using the wrong liner size in the wrong place.
| Method Tried | Result | Drawback |
|---|---|---|
| Using light liners for wet kitchen scraps | Worked for small amounts of dry or low-moisture scraps | Became less reliable with coffee grounds, sauces and heavier food scraps |
| Using one liner size across all food waste points | Simple for ordering | Poor fit in some bins, more stretching, harder staff handling |
| Using small caddy liners for high-volume food waste | Fine for low-volume collection | Filled too quickly and required frequent changeover |
| Using wheelie bins without suitable liners | Reduced liner cost | Increased bin cleaning, odour and bin juice risk |
| Using thicker, size-matched compostable liners | Better fit and handling across food waste points | Requires businesses to choose different sizes for different areas |
Choosing the right Compostar liner size
For business food waste collection, the best liner is not always the largest one. The better approach is to match each food waste point to the most suitable liner size.
A café may need 18L or 36L liners near counters and staff kitchens. A commercial kitchen may need 80L liners for wetter back-of-house food waste. Larger sites may need 120L or 240L liners for wheelie bins, transfer points and waste rooms.
This helps reduce poor bin fit, overfilling, stretching, staff handling problems and unnecessary cleaning.
