Cardboard is one of the most environmentally friendly packaging materials on the market. Corrugated cardboard is 100% natural, renewable and biodegradable. Not only that, but it is also highly durable and versatile. Nine out of ten packages are recovered, making it a highly sustainable, ductile and strong material. Remember that paper and cardboard represent 30% of all waste. Cardboard is disposed of in the same way as paper. However, it is important to avoid wet or soiled cardboard: once corrupted, cardboard should not be discarded as paper waste because it cannot be recycled and could clog automatic material sorting mechanisms. Cardboard is also crushed, ground and destroyed and finally recycled.
