For the last 15 years, compliance with the EU Essential Requirements for Packaging was demonstrated using the EN standards for packaging that were developed by CEN (the European Committee for Standardization). As part of a global approach, ISO stepped in to develop a framework that would both align with and update the EN standards, making them more modern and relevant. The standards focus on four main concepts among :
• Packaging optimization. Unlike the EN standards, the goal is not simply source reduction. Packaging has an instrinsic value and that sometimes more packaging may be better than less.
• Evaluation for heavy metals and dangerous substances. The ISO standard utilizes the Globally Harmonized System (GHS) to evaluate substances that may be in packaging that could be considered hazardous if released into the environment.
• Demonstrated end-of-life options for packaging. All packaging must be recoverable through at least of the following: material recycling, organic recycling, or energy recovery.”
