ISO 17556 Plastics Aerobic Biodegradability in Soil
The ISO 17556 standard specifies a method to determine the aerobic biodegradability of plastics in soil. This test evaluates how efficiently plastic materials decompose under controlled soil conditions, which is crucial for assessing their environmental impact and recyclability.
This service is particularly important for waste management and recycling testing, especially focusing on plastic and polymer recycling. Understanding a material's biodegradability helps manufacturers design products that are more sustainable and reduces the burden of waste disposal. This test contributes to compliance with international standards and regulatory requirements, ensuring that materials meet environmental stewardship goals.
The ISO 17556 protocol involves placing samples in soil under specified conditions for a defined period. The biodegradation is measured by tracking CO2 production as an indicator of microbial activity breaking down the plastic components. This method provides insights into how quickly and thoroughly plastics can decompose, which is vital information for R&D engineers, quality managers, and compliance officers.
For accurate results, specimen preparation must be precise. This includes ensuring that samples are representative of the material being tested, cutting them to specified dimensions, and conditioning them under controlled conditions before testing. The environmental conditions during biodegradation, such as temperature, humidity, and soil type, significantly influence the outcome.
Instrumentation plays a critical role in this process. Automated systems can monitor CO2 production continuously, providing real-time data on the rate of biodegradation. This allows for more accurate assessments compared to manual methods. The testing period is typically 90 days, but longer durations may be used depending on specific requirements or material characteristics.
The results from this test are reported in terms of the percentage of CO2 produced relative to a reference compound like glucose. Compliance with ISO standards ensures that these tests are consistent and comparable across different laboratories and regions. This consistency is essential for regulatory compliance and international trade.
Understanding the biodegradability of plastics helps in making informed decisions about material selection, process optimization, and product design. For instance, materials that show high biodegradability can be promoted as sustainable alternatives, enhancing market competitiveness and consumer acceptance. Additionally, this service supports environmental sustainability goals by providing data to inform circular economy practices.
Specimens tested under ISO 17556 are typically plastics intended for recycling or those used in applications where their environmental impact is critical. Examples include biodegradable plastic films, packaging materials, and garden mulches. The test results can influence procurement strategies by guiding the selection of more environmentally friendly materials.
