10 How is paper recycled? Paper is one of the easiest materials to recycle. Paper is collected from our kerbside or recycling banks by local authorities and waste management companies. Once the paper is collected it is then: Sorted, graded and delivered to a paper mill. Once at the paper mill it is added to water and then turned into pulp. The paper is then screened, cleaned and de-inked through a number of processes until it is suitable for papermaking. It is then ready to be made into new paper products such as newsprint, cardboard, packaging, tissue and office items. It can take just seven days for a newspaper to go through the recycling process and be transformed into recycled newsprint which is used to make the majority of Britain’s national daily newspapers.
