Compostable Bin Liners

Product Overview

Compostable bin liners, also widely referred to as biodegradable plastic bags or coloured compostable waste bags, are designed to simplify food waste sorting and support sustainable waste management systems. The distinctive green tint of these liners serves as a clear visual cue for users, distinguishing compostable bags from conventional plastic waste bags to reduce sorting errors. Manufactured by AISUNBIO, these liners use a plant-derived green pigment that is fully certified within the overall compostable scope, with no petrochemical dyes added to the material. The product range is available in three capacity options: 10L for kitchen caddies, 30L for bathroom bins, and 50L for outdoor compost bins, covering common household and commercial waste collection needs. The lightweight yet strong material can withstand typical wet food waste loads without tearing or leaking, ensuring reliable performance during daily use. These liners are popular with retailers positioning their own-brand liner ranges as premium, as well as zero-waste stores and eco-branded supermarket own-label lines, aligning with consumer demand for sustainable, easy-to-use waste management products.

Core Certifications & Compliance

These compostable bin liners hold multiple internationally recognized certifications to ensure compatibility with global composting programs and regulatory requirements. First, the product is TÜV HOME & INDUSTRIAL certified, verifying that it meets compostability standards for both home composting environments and industrial composting facilities. For the North American market, the liners are BPI certified, which is a mandatory requirement for acceptance into most North American municipal organics collection programs, ensuring that waste collected in these bags can be processed through local composting systems without issues. For the European Union market, the liners are EN 13432 certified, meeting the strict EU standards for compostable packaging, ensuring acceptance into EU municipal compost programs. All certifications cover the entire product, including the plant-derived green pigment, so the coloured liners do not compromise compostability or compliance with local waste processing rules.

Key Product Advantages

1. Clear Sorting Cue: The green tint of the liners provides an immediate visual signal that the bag is compostable, reducing sorting errors by users and waste management staff, which improves the efficiency of organics collection programs. Unlike clear or white compostable bags that can be mistaken for conventional plastic, the green colour eliminates confusion, ensuring that compostable waste is not sent to landfill.
2. Plant-Derived Pigment: The green colour is achieved using a plant-derived pigment, with no petrochemical dyes added. This means the entire bag, including the colouring agent, is fully compostable, so it breaks down completely in composting facilities without leaving microplastics or harmful residues.
3. Strong, Leak-Resistant Design: The lightweight PBAT + PLA blend material is engineered to hold up to 5kg of wet food waste without tearing or leaking. The star seal bottom design further enhances load-bearing capacity and prevents leaks, making the liners suitable for wet food waste such as fruit peels, vegetable scraps, coffee grounds, and other organic waste.
4. Multi-Market Compliance: With BPI certification for North America and EN 13432 certification for the EU, these liners are compatible with most municipal organics collection programs globally, making them suitable for brands and retailers operating across multiple regions.
5. Retail-Friendly Packaging: The liners are available in rolls of 25, packaged in either printed boxes or retail sleeves, which are designed for end-consumer display. This format is convenient for retail shelves, allowing customers to easily purchase the liners for household use, and supports own-brand product lines for supermarkets and eco-stores.

Target Customer Segments

These compostable bin liners are designed to serve a range of B2B customers across the sustainable waste management and retail sectors. Primary target segments include: zero-waste retail stores that specialize in eco-friendly household products, supermarket chains developing eco-branded own-label waste product lines, municipal waste management organizations running organics collection programs, commercial food service providers such as restaurants, cafes, and corporate cafeterias that need to manage food waste sustainably, sustainable packaging distributors serving retail and commercial clients, and eco-focused consumer brands looking to reduce the environmental impact of their product packaging and waste management offerings. The product’s compliance with multiple global certifications makes it suitable for customers operating in both North American and European markets, as well as other regions with established composting infrastructure.

Application Scenarios

The compostable bin liners are versatile enough to cover a wide range of household and commercial waste collection scenarios. For household use, the 10L liners are perfectly sized for kitchen caddies, where users collect daily food scraps such as fruit and vegetable peels, eggshells, coffee grounds, and tea bags. The 30L liners are suitable for bathroom bins, collecting organic waste such as used cotton balls, natural hair, and biodegradable personal care product packaging. The 50L liners are designed for outdoor compost bins or larger household waste bins, holding larger volumes of food and yard waste. For commercial use, the liners are ideal for restaurants and cafes to collect food waste from kitchen prep areas and customer dining spaces, for office buildings to provide composting options for employees, and for municipal waste programs to distribute to households as part of their organics collection service. The green tint ensures that users can easily identify the correct bin for compostable waste, reducing contamination of recycling and compost streams.

Industry Pain Points Addressed

The compostable bin liners are designed to solve several common pain points in sustainable waste management and retail packaging. First, a major issue in organics collection programs is contamination: many users mistake clear compostable bags for conventional plastic bags, leading to entire batches of compost being rejected because of non-compostable plastic waste. The green tint of these liners eliminates this confusion, reducing contamination rates and improving the efficiency of composting programs. Second, many coloured compostable bags use petrochemical dyes that are not compostable, meaning the coloured bags cannot be accepted into composting facilities, even if the base material is compostable. The plant-derived pigment used in these liners is fully compostable, so the entire bag breaks down without leaving harmful residues, solving the problem of coloured compostable bag non-compliance. Third, conventional compostable bags often tear easily when holding wet food waste, leading to leaks and messy waste collection. The strong PBAT + PLA blend and star seal bottom design can hold up to 5kg of wet waste, eliminating leaks and tearing issues. Fourth, many retailers struggle to find compostable liners that are compatible with both North American and European certification standards, requiring them to source different products for different markets. These liners hold both BPI and EN 13432 certifications, allowing retailers to use the same product across multiple regions, reducing sourcing complexity and inventory costs.

Sustainable Value Proposition

By choosing these compostable bin liners, customers can reduce their environmental footprint while improving the efficiency of their waste management systems. The liners are designed to break down completely in composting facilities, diverting organic waste from landfill where it would otherwise produce methane, a potent greenhouse gas. The plant-derived material and pigment reduce reliance on fossil fuel-based plastics and dyes, aligning with global sustainability goals. For retailers, offering these certified compostable liners allows them to meet growing consumer demand for eco-friendly household products, strengthening their brand reputation as a sustainable business. For municipal waste programs, the clear sorting cue reduces contamination rates, making composting programs more cost-effective and efficient, which encourages more households to participate in organics collection. Overall, these liners provide a practical, easy-to-use solution for sustainable waste management, bridging the gap between consumer convenience and environmental responsibility.
