Biodegradable vs. Compostable: Understanding the Difference in Sustainable Materials
Introduction:
In today's world, the importance of sustainable materials is more evident than ever. As consumers become increasingly eco-conscious, understanding the distinction between biodegradable and compostable materials plays a crucial role in making informed choices. In this blog post, we will explore the difference between biodegradable and compostable materials, shedding light on their environmental impact and applications. Join us as we delve into this topic and discover the significance of these sustainable materials for InkBuiltUK's commitment to a greener future.
1. Biodegradable Materials:
Biodegradable materials are capable of breaking down naturally over time through the action of microorganisms. These materials decompose into simpler organic compounds, returning to the environment without leaving behind harmful residues. It is important to note that the breakdown process may vary depending on factors such as temperature, humidity, and the presence of microorganisms.
2. Compostable Materials:
Compostable materials, on the other hand, are a specific subset of biodegradable materials. Compostable materials not only break down into organic compounds but also contribute to the nutrient-rich composition of compost when subjected to specific conditions. These conditions typically involve controlled composting processes, including specific temperature ranges, moisture levels, and aeration.
3. Environmental Impact:
a. Biodegradability: Biodegradable materials offer the advantage of reducing waste accumulation, as they break down over time and minimise the burden on landfills. However, it is important to ensure that the degradation process does not result in the release of harmful substances or contribute to pollution.
b. Composting: Compostable materials support the creation of nutrient-rich compost, which can be used to enrich soil and promote sustainable agriculture. When compostable materials undergo proper composting, they contribute to the circular economy by returning valuable nutrients back to the environment.
4. Applications:
a. Biodegradable Materials: Biodegradable materials find applications in various industries, including packaging, disposable utensils, and single-use products. These materials help reduce waste and environmental impact in scenarios where long-term durability is not required.
b. Compostable Materials: Compostable materials are commonly used in compostable packaging, food containers, and certain agricultural applications. They are designed to be composted in specialised facilities, allowing for the creation of nutrient-rich compost.
5. Certifications and Standards:
Various certifications and standards exist to ensure the authenticity and environmental integrity of biodegradable and compostable materials. Examples include the ASTM D6400 and EN 13432 certifications, which verify the compostability of materials under specific conditions. InkBuiltUK ensures compliance with these certifications when incorporating biodegradable and compostable materials into their product range.
Conclusion:
Understanding the difference between biodegradable and compostable materials is essential in making sustainable choices. Both play a vital role in reducing waste and minimising environmental impact. By incorporating biodegradable and compostable materials into their products, We take significant strides toward a greener future. Join us in our commitment to sustainable materials, and together, let's embrace a more eco-conscious lifestyle.

In the United Kingdom, several standards and certifications are in place to ensure the authenticity and environmental integrity of biodegradable and compostable materials. Here are some British standards and certifications commonly referenced in relation to these materials:
BS EN 13432: Packaging - Requirements for Packaging Recoverable through Composting and Biodegradation: This standard specifies the requirements for packaging materials and products that are designed to be composted and biodegraded in specific composting conditions. It covers criteria such as material composition, biodegradability, disintegration, and ecotoxicity.
BS EN 14995: Characterisation of Sludge - Biodegradability Test for Leaching of Organic Compounds: This standard focuses on the assessment of the biodegradability of organic compounds present in sludge. While not specific to packaging or materials, it can be relevant when considering the environmental impact of compostable materials on sludge.
Compostable Packaging Standard (CPS): The Compostable Packaging Standard is a certification program managed by the Renewable Energy Association (REA) in the UK. It verifies that packaging products meet the requirements of compostability outlined in BS EN 13432. The CPS certification ensures that the materials and packaging products can be safely composted and do not cause harm to the environment.
Seedling Logo Certification: The Seedling logo is an internationally recognised certification mark managed by DIN CERTCO, a German certification body. It confirms that packaging materials meet the requirements of the European standard EN 13432. Products bearing the Seedling logo demonstrate their compostability in industrial composting facilities.
OK Compost Certification: The OK Compost certification is another internationally recognised certification program administered by TÜV Austria. It verifies that materials meet the requirements of EN 13432 and can be safely composted in industrial composting facilities.
Home Compostable Certification: The Home Compostable certification, managed by TÜV Austria, verifies that products can be composted in home composting systems. This certification indicates that the materials will break down effectively in domestic composting conditions.
When incorporating biodegradable and compostable materials into our products, We ensure compliance with relevant certifications and standards to ensure the authenticity and environmental integrity of our offerings. By adhering to these certifications, InkBuiltUK demonstrates its commitment to sustainability and responsible material selection.
