Thinking Outside the Box

摘要

Tetra Pak is committed to being a world leader in sustainable recycling, by promoting and encouraging effective widespread carton recycling programs. The company strives to achieve a 40 per cent global carton recycling rate by 2020, doubling the rate world-wide from 2010. On average, "gable top" cartons are 80 per cent fibre and 20 per cent polyethylene, and "aseptic" cartons are 74 per cent fiber, 22 per cent polyethylene and four per cent aluminum. Cartons have high-quality virgin bleached long fibre and the ink is on the polyethylene layer and not the fibre. This makes cartons attractive to mills that can separate fibre from the poly/aluminum. Some end-users can also use the poly/ aluminum either as feedstock or fuel.
