Compostable Bin Liners

These BPI-certified compostable bin liners are designed in convenient dispenser box format, perfectly suited for kitchen compost collection needs. These products are often marketed as biodegradable plastic bags or biodegradable bags, and are the dominant format for household food waste collection programs in the UK and Germany. AISUNBIO’s roll-format liners are engineered to precisely fit standard 7L and 10L kitchen caddies issued under municipal waste collection schemes. The perforated roll design allows users to tear off exactly one bag at a time without tangling, making dispensing intuitive and hassle-free. An optional breathable micro-perforation feature reduces condensation buildup inside the caddy, minimizing anaerobic conditions that lead to unpleasant odors. The compact roll structure takes up minimal storage space in drawers or under-sink cabinets, making it ideal for residential kitchen use. All roll formats maintain TÜV Austria OK Compost INDUSTRIAL certification, and the liners are fully compatible with all major UK council compost collection schemes, ensuring they are accepted at municipal compost facilities without issue. Custom print on the roll core sleeve is available for brands looking to add custom branding elements to their waste collection products.

Key Design Features

1. Perforated roll dispensing: The pre-perforated roll format eliminates tangling, allowing users to tear off a single bag cleanly and efficiently, no fumbling with tangled rolls or multiple bags coming loose at once.
2. Precision caddy fit: Engineered to match the exact dimensions of standard 7L and 10L UK and EU kitchen caddies, the liners sit securely inside the caddy without slipping, bunching, or leaving excess material hanging over the rim.
3. Industrial compostability compliance: Certified to EN 13432 standards, the liners are accepted by municipal industrial composting facilities across the EU and UK, eliminating the risk of waste being rejected at collection points.
4. Optional micro-perforation: The breathable micro-perforation option allows consistent airflow inside the caddy, reducing moisture condensation that creates anaerobic environments and causes strong, unpleasant odors between collection days.
5. Space-saving roll design: The compact roll format occupies minimal storage space, fitting easily in kitchen drawers, under-sink cabinets, or small pantry areas without taking up valuable storage real estate.
6. Star seal bottom construction: The star seal bottom design prevents leaks and tears, even when holding wet food waste, ensuring no messy spills inside the caddy or during transport to collection points.
7. Custom core sleeve printing: Custom print on the roll core sleeve is available, allowing brands, municipal programs, or retailers to add custom messaging, branding, or collection instructions directly on the roll packaging.

Target Customer Segments

This product is ideal for a range of B2B customers operating in the UK and EU markets, including municipal waste management authorities running household food waste collection programs, retail chains selling household waste management products to residential customers, sustainable lifestyle brands looking to expand their eco-friendly product lines, commercial property management companies supplying waste bins and liners to residential buildings, and wholesale distributors serving the household cleaning and waste product market. The product’s compliance with local composting standards makes it a reliable choice for customers looking to align with EU and UK circular economy goals, reduce plastic waste, and provide residents with easy, compliant food waste collection solutions.

Application Scenarios

These compostable bin liners are designed exclusively for kitchen food waste collection, fitting seamlessly into daily household routines. Common use cases include lining standard kitchen countertop compost caddies to collect fruit and vegetable peels, coffee grounds, tea bags, eggshells, and other food scraps before weekly municipal collection. The liners are also suitable for use in small office kitchen areas, community shared kitchens, and student accommodation facilities that participate in local compost collection schemes. The compact roll format means the product can be stored near kitchen waste stations for easy access, and the leak-proof star seal design ensures no mess when transferring full bags from the kitchen caddy to larger outdoor compost bins or curbside collection points. For municipal programs, the dispenser box format makes the product easy to distribute to residents as part of welcome kits for new food waste collection scheme participants, or to sell at local council offices and community centers.

Industry Pain Points Addressed

1. Contamination issues in compost streams: Many generic biodegradable bags do not meet EN 13432 standards, leading to contamination of municipal compost batches, increased processing costs, and rejected waste loads. These certified liners eliminate that risk, ensuring compost streams remain clean and compliant with processing facility requirements.
2. Poor bag fit leading to user frustration: Generic bin liners often slip inside caddies, bunch up, or are too large to fit neatly, leading users to avoid using the liners entirely and dump loose food waste directly into caddies, creating messy, hard-to-clean surfaces. The precision fit of these liners removes that friction, making it easier for residents to consistently use compost collection systems.
3. Odor complaints from residents: Anaerobic condensation in sealed caddies leads to strong odors that draw complaints from residents, leading to low participation rates in municipal compost programs. The optional micro-perforation feature reduces that odor buildup, improving resident satisfaction and program participation rates.
4. Tangled roll dispensing issues: Traditional roll bags often tangle when users try to pull one bag free, leading to wasted product, frustration, and messy storage. The perforated roll design eliminates tangling, creating a smooth, intuitive user experience.
5. Storage space constraints in small kitchens: Many households have limited under-sink or drawer storage, making bulky bin liner packages impractical. The compact roll design of these liners takes up minimal space, making them accessible for even the smallest urban kitchens.
6. Leakage and mess during waste transport: Weak seal points on generic liners often leak when holding wet food waste, creating stains on caddies, floors, and curbside collection areas. The star seal bottom design adds extra leak protection, reducing mess and cleaning requirements for both residents and waste collection teams.

Sustainability Impact

By using certified compostable bin liners, households and municipal programs can significantly reduce the amount of plastic waste sent to landfills, as the liners break down fully in industrial composting facilities alongside food waste, creating nutrient-rich compost that can be used to improve soil health in agricultural and landscaping applications. The availability of recycled and PCR material options further reduces the carbon footprint of the product, aligning with EU and UK circular economy targets to cut single-use plastic consumption and increase waste diversion from landfills. The high acceptance rate of these certified liners also helps improve participation rates in municipal food waste collection programs, increasing the overall volume of food waste diverted from landfills, where it would otherwise release methane, a potent greenhouse gas. For brands and retailers, offering these certified compostable liners allows them to meet growing consumer demand for sustainable, zero-waste household products, building brand loyalty among environmentally conscious customers.
