EN 13705 Nitrous Oxide Emissions from Compostable Waste
The European Standard EN 13705 is one of the most important regulatory frameworks for compostable materials, particularly in waste management and recycling. This standard provides a standardized method to determine nitrous oxide emissions during the decomposition process of biodegradable plastics. Nitrous oxide (N2O) is a potent greenhouse gas with global warming potential 310 times greater than that of carbon dioxide over a 100-year period, making this test crucial for ensuring the environmental impact of compostable waste.
The test outlined in EN 13705 is designed to evaluate whether compostable materials meet the biodegradable and nontoxic requirements set by regulatory bodies such as European Commission Directive 2008/98/EC. The standard covers a range of parameters including moisture content, temperature conditions, and the presence of microorganisms that play a crucial role in the decomposition process.
The testing procedure involves incubating the compostable material under controlled conditions for up to 12 weeks. During this period, any nitrous oxide produced by the material is measured using an infrared gas analyzer or similar device capable of detecting trace amounts of gases. The results are then compared against predefined thresholds set in the standard.
The importance of this test cannot be overstated, especially given the growing demand for sustainable waste management solutions. Many countries around the world have adopted stringent regulations to control nitrous oxide emissions from organic waste to mitigate their environmental impact. This testing ensures that compostable materials truly meet these standards and can be safely utilized in recycling programs.
Compostable packaging and other materials often contain additives designed to enhance biodegradability, but not all of them perform as advertised under real-world conditions. By adhering to the rigorous protocols outlined in EN 13705, manufacturers can demonstrate that their products are environmentally friendly and meet international standards.
The test also helps companies comply with increasingly stringent environmental regulations. For instance, some regions require compostable materials to have a maximum nitrous oxide emission rate of less than 2 mg N2O/kg dry matter after a defined period in controlled conditions. Ensuring compliance with these regulations can significantly reduce legal risks and enhance brand reputation.
- Preparation: Specimens must be representative samples taken from the production batch and prepared according to specific guidelines provided by EN 13705.
- Incubation: Samples are incubated at specified temperatures (typically between 40°C and 60°C) for periods ranging up to 12 weeks. The duration depends on the type of material being tested.
The results from this test provide valuable insights into the environmental performance of compostable materials, helping stakeholders make informed decisions about product design, manufacturing processes, and waste management strategies.
Why Choose This Test
Selecting EN 13705 testing for nitrous oxide emissions is essential for several reasons. Firstly, it ensures compliance with international environmental regulations, which is increasingly important as countries around the world adopt stricter standards to combat climate change. By adhering to this standard, manufacturers can avoid costly fines and legal disputes associated with non-compliance.
Secondly, this test provides critical data that helps improve product performance and sustainability. Through rigorous testing, companies can identify areas for improvement in their compostable materials, leading to enhanced biodegradability and reduced environmental impact. This not only benefits the environment but also enhances the reputation of brands committed to sustainable practices.
Thirdly, EN 13705 testing supports research and development efforts aimed at creating more effective compostable materials. By understanding how different additives affect nitrous oxide emissions, scientists and engineers can innovate new products that better meet environmental goals. This continuous improvement cycle is vital in an ever-evolving regulatory landscape.
Finally, this test fosters trust among consumers who are increasingly concerned about the environmental footprint of their purchases. By demonstrating adherence to high standards like EN 13705, companies can build stronger relationships with environmentally conscious customers, potentially increasing market share and brand loyalty.

The reliability of our testing services is further enhanced by strict quality control measures and adherence to ISO 17025 accreditation standards. This ensures that the results are not only accurate but also repeatable, providing confidence in the integrity of every test conducted.
We employ state-of-the-art equipment such as gas chromatographs with mass spectrometers (GC-MS) for precise measurement of nitrous oxide emissions. These instruments allow us to detect even trace amounts of gases, ensuring that no potential issues go unnoticed.
Use Cases and Application Examples
- Compostable Packaging: Testing nitrous oxide emissions from packaging helps companies ensure their products meet regulatory requirements for biodegradability. This is particularly important in the food service industry where single-use items contribute significantly to waste.
- Bio-Based Plastics: For manufacturers of bio-based plastics, this test ensures that their materials decompose safely and do not release harmful gases during composting processes.
The results from EN 13705 testing are widely used in various sectors including agriculture, where the decomposition process can improve soil health. In urban settings, these tests help manage waste more effectively by identifying materials that can be safely composted rather than sent to landfills.
Additionally, this test is crucial for research and development teams working on new biodegradable products. By providing detailed data on nitrous oxide emissions, it aids in the optimization of material formulations and processing techniques.
A real-world example involves a major fast-food chain that switched to compostable packaging made from plant-based materials. Before launching this product, they conducted EN 13705 testing to ensure compliance with local regulations and to verify that the packaging would decompose safely in industrial composting facilities.
