Eco-Conscious Waste Solutions
Transition to an environmentally responsible waste management system with our range of wholesale compostable liners. Manufactured for trade, they are engineered to decompose naturally alongside your organic waste, helping to reduce landfill reliance and enrich composting materials.
Naturally Decomposing Materials
Our compostable liners are specifically engineered to provide an eco-friendly alternative to traditional plastic bags. Made from plant-based, natural starches, these liners are designed to break down completely in industrial composting facilities, leaving no microplastics or harmful residues behind.
This process allows them to turn into naturally benign materials, helping to reduce landfill waste and support corporate sustainability initiatives. They offer a strong and reliable way to collect organic waste while significantly minimizing your ecological footprint.
Certified Performance (EN 13432)
Choosing the right compostable product is essential to prevent contamination in recycling streams. Our starch-based compostable bags meet stringent European (EN 13432) industry standards. This certification guarantees they break down efficiently in industrial composting conditions, giving you verified confidence in your organic waste disposal.
Versatile for Food & Organic Waste
The applications for our compostable liners are extensive. They are perfect for collecting food waste in commercial kitchens, restaurants, and office caddies. They are also highly effective for council and commercial garden waste disposal.
Note on storage: Because they are designed to break down, our compostable liners have a shelf life of up to 12 months. We recommend storing them in a cool, dry place out of direct sunlight.

Frequently Asked Questions
How do compostable liners differ from traditional plastic liners?
The key difference lies in their material and disposal process. Traditional plastic liners are made from petroleum-based plastics and can take hundreds of years to break down. In contrast, our compostable liners are made from renewable, plant-based materials and are certified to completely biodegrade in an industrial composting environment.
Are your compostable liners certified?
Yes, our compostable bags meet strict EN 13432 industry standards for compostability. This certification confirms that they will effectively break down in commercial composting facilities, leaving behind no microplastics or harmful residues.
Can compostable liners be used for all types of waste?
While our compostable liners are specifically designed for organic waste like food and garden debris, they are not suitable for heavy-duty, general, or sharp waste, as they are naturally designed to break down. For heavier general refuse, we recommend our standard recycled polythene commercial bags.
What is the shelf life of compostable liners?
Our compostable liners have a shelf life of up to 12 months. To maintain their strength and integrity before use, we strongly recommend storing them in a cool, dry place away from direct sunlight and using them as soon as is practical.
