What is EN ISO 14855-1:2012?

EN ISO 14855-1:2012 is a professional technical standard that provides guidelines for the determination of the ultimate aerobic biodegradability of plastic materials exposed to controlled composting conditions.

Introduction

In today's world, where plastics play an integral role in various industries, it is crucial to ensure their environmental impact is minimal. EN ISO 14855-1:2012 sets out specific requirements and methodologies to assess the biodegradation of plastics under simulated composting conditions.

The Scope of EN ISO 14855-1:2012

This standard focuses on determining the ultimate aerobic biodegradability of plastic materials by composting them. It specifies the test conditions, including temperature, humidity, and composition of the composting medium. The standard also outlines the requirements for sampling, preparation of test specimens, and data analysis.

The Testing Procedures

In order to determine the biodegradability of a plastic material according to EN ISO 14855-1:2012, several steps must be followed:

Sample Preparation: The plastic material is cut into small pieces and any contaminants are removed.

Composting Conditions: The prepared samples are placed in a composting environment with controlled temperature, moisture, and air supply.

Monitoring: Throughout the composting process, various parameters, such as temperature, pH, and gas production, are monitored.

Data Analysis: After a specified period (typically 8 weeks), the remaining mass of the plastic material is measured and compared to the initial mass to determine its biodegradability percentage.

Benefits and Importance

The EN ISO 14855-1:2012 standard provides a reliable and standardized method for assessing the biodegradability of plastic materials. Its importance lies in guiding manufacturers, researchers, and regulatory bodies in making informed decisions regarding the environmental impact of plastics. By using this standard, stakeholders can identify plastic materials that are compostable, leading to a reduction in waste accumulation and promoting sustainable practices.

In conclusion, EN ISO 14855-1:2012 is a significant technical standard that determines the ultimate aerobic biodegradability of plastics under controlled composting conditions. Its guidelines and testing procedures play a vital role in assessing the environmental impact of plastic materials and promoting more sustainable practices in various industries.
