How to Recycle Bio-Waste Properly: A Practical Guide for Households and Communities

by

Across Europe, bio-waste plays a key role in the transition to a circular economy. Yet a large part of it still ends up in mixed waste streams where it cannot be recovered. Bio-waste represents the largest single component of municipal waste in the EU, making its effective collection and treatment particularly important. The European Environment Agency stresses that proper bio-waste collection helps reduce landfill, cut greenhouse gas emissions, and turn organic matter into valuable compost and digestate. To reach these benefits, we all need to sort smarter and reduce contamination at home.

This guide brings together LANDFEED’s key recycling tips to help households and communities sort bio-waste correctly and support sustainable waste systems.

Sort It Right: What Belongs in the Brown Bin

Correct sorting forms the basis of effective bio-waste recycling. Correct sorting forms the basis of effective bio-waste recycling. Local collection systems differ, but commonly collected bio-waste can include food scraps and garden waste. Depending on local rules, this may include:

  • Raw fruit and vegetable scraps
  • Eggshells
  • Coffee grounds
  • Garden clippings
  • Compostable paper, where allowed

When correctly sorted and processed, bio-waste can be transformed into compost or digestate that can be used as a soil improver or fertiliser.

If in doubt, check your municipality’s guidelines. A quick check avoids mistakes and keeps recycling streams clean.

Keep Plastics and Packaging Out of the Bio Bin

Items such as conventional plastic produce stickers, tea bags containing plastic or unsuitable bags can contribute to contamination in composting systems. This contamination can lower the quality of compost and make the recycling of bio-waste more difficult.

Where compostable bags are accepted by the local collection system, look for recognised certification such as EN 13432. Always check local guidelines before using them in the bio-waste bin. European Bioplastics offers guidance on how to identify compostable materials and understand relevant certification.

Understand “Compostable” vs “Biodegradable”

These terms often confuse consumers. All compostable materials are biodegradable, but not all biodegradable items are compostable. “Biodegradable” may simply mean that an item breaks down under certain environmental conditions and within a particular timeframe, which does not necessarily make it suitable for composting.

Products labelled only as “biodegradable” should not automatically be placed in the bio-waste bin, as biodegradability does not necessarily mean they are suitable for industrial composting.

A simple rule works well: check for recognised compostability certification and, above all, follow your local collection guidelines.

Join or Start a Community Composting Hub

Community composting offers a solution when households lack garden space and can complement municipal bio-waste collection. These hubs bring neighbours together, create compost for local gardens and help keep organic material within local cycles.

Home and community composting can also reduce the amount of bio-waste that needs to be collected and processed centrally.

Keep the Bio-Waste Free from Contamination

Good sorting means keeping materials that do not belong in the bio-waste stream out of the bin. Conventional plastics and other non-compostable materials can contaminate bio-waste and affect the quality of the resulting compost.

Always follow your municipality’s instructions on what can and cannot be placed in the bio-waste bin. Local guidance may also specify which bags or liners can be used.

Recycle Garden Waste Correctly

Garden waste, including biodegradable plant material, can also be recycled or composted. However, collection systems vary, and some municipalities collect garden waste separately or place restrictions on the type and size of material accepted.

Always check your local guidelines before adding garden waste to your bio-waste bin or collection.

Follow Local Rules for Municipal Collection

Although EU legislation requires bio-waste to be separated and recycled at source or collected separately, the materials accepted by local collection systems can vary. Some cities accept cooked food and compostable packaging; others have different requirements depending on their collection and treatment systems.

These differences can reflect local infrastructure and processing technology. Before sorting, review your municipality’s accepted materials.

Use Technology to Improve Sorting

Digital tools can also help households prevent food waste and make better use of available food. Apps can help users keep track of food, redistribute surplus or better understand how much food they throw away.

FAO has also developed digital tools that use food-waste data to help identify opportunities for waste reduction.

Clean Sorting Creates Real Value

Recycling starts at home. When bio-waste is correctly separated, it can be processed through composting or anaerobic digestion to produce compost, digestate and, in the case of anaerobic digestion, biogas. Compost and digestate that meet relevant quality requirements can be used as soil improvers and fertilisers.

Good sorting also supports projects like LANDFEED, which rely on high-quality organic matter to develop bio-based products.
