EN 13706 Biogas Yield from Organic Waste
The European Standard EN 13706 outlines a procedure to determine the biogas yield of organic waste. This standard is pivotal for quality managers, compliance officers, R&D engineers, and procurement teams involved in the field of waste management and recycling testing. It provides a standardized method to assess the potential energy recovery from organic waste materials through anaerobic digestion.
The determination of biogas yield is essential for assessing the environmental impact and economic viability of compostable waste streams. This standard ensures that all participants in the waste management industry can accurately measure, compare, and improve their processes, thereby promoting sustainable practices.
Organic waste, such as food residues, yard trimmings, and paper products, is a significant component of municipal solid waste. The biogas yield from this organic matter can be harnessed for energy production, contributing to the circular economy by reducing landfill use and greenhouse gas emissions.
The testing procedure involves several steps including sample preparation, inoculation with specific microorganisms, incubation under controlled conditions, and measurement of biogas produced over a set period. The standard provides detailed guidelines on the type of containers used, temperature control, pH management, and other crucial parameters to ensure consistent results.
Compliance with this standard is particularly important for facilities that handle organic waste in industrial-scale anaerobic digestion plants or those involved in research and development aimed at improving waste-to-energy processes. Accurate biogas yield data helps in optimizing operational efficiency and meeting regulatory requirements related to renewable energy targets.
Applied Standards
| Standard Code | Description |
|---|---|
| EN 13706:2005 | Determination of biogas yield from organic waste in laboratory scale digestion plants. |
| ISO 10145-1:2019 | Biodegradable plastics – Determination of biodegradation and composting performance – Part 1: Laboratory test methods for biodegradation (biostability) in a defined medium at 58°C. |
| ASTM D5511-04(2019) | Determination of biodegradability of plastic materials by the controlled composting method – Test conditions and procedures. |
These standards complement EN 13706 by providing additional methodologies for assessing the degradability and environmental impact of organic waste, ensuring a comprehensive approach to sustainability in the waste management sector.
Scope and Methodology
| Key Elements | Description |
|---|---|
| Sample Preparation | The organic waste sample must be homogenized, dried if necessary, and ground to a particle size suitable for the digestion process. |
| Inoculum Use | A defined inoculum of microorganisms is used to initiate anaerobic digestion in the laboratory-scale reactor. |
| Incubation Conditions | The digestion reactor is maintained at a constant temperature and pH level conducive to microbial activity. Gaseous output is monitored over a predetermined period. |
| Data Collection | Biogas production rates are recorded every 24 hours for several weeks, allowing for the calculation of total biogas yield per unit mass of organic waste. |
The methodology ensures that the test conditions closely mimic those in industrial anaerobic digestion plants, providing reliable data on biogas potential. This standardized approach is crucial for consistent results and meaningful comparisons between different waste streams or treatment processes.
