These 3Rs are now implemented in many testing establishments worldwide and have been adopted by various pieces of legislation and regulations. [2]
Effective recycling programs can significantly reduce the need for virgin materials and the environmental impacts associated with extracting and processing those materials. Product life-cycle analysis (LCA) is a comprehensive method for evaluating the environmental impacts associated with all stages of a product's life.
