Recycling Cardboard When cardboard is recycled, it is first shredded and combined with large amounts of water, additional pulp, and is then stirred until it breaks down into individual fibres. All foreign objects are removed by using special filters and the cardboard is de-inked. Once the pulp is clean, it is ready to be drained and dried, through a series of rollers that flattens the pulp and removes remaining moisture. All the meshed pulp is ridged by specially geared machines, the linerboards are glued on, and the resulting flat pieces are trimmed to size and creased along a pattern of folds to make two types of cardboard: Boxboard Cardboard, made as a solid sheet used for products like shoe boxes & Corrugated Cardboard, made like a paper sandwich of linerboard and a ribbed inner layer and used to make boxes in which appliances are packaged. Corrugated cardboard manufactured from recycled pulp uses about 75% of the processed energy used in the manufacture of corrugated cardboard made from virgin pulp. Nonetheless, every time cardboard is recycled, the fibres become weaker limiting the number of times it can be recycled, usually up 8 times. Remember!
