- Recycled paper and board used for waste pulp is often used for lower grade paper - it's strength, colour and durability is not as good as virgin fibres.
- Waste pulp is mixed with virgin fibres to make better quality papers as fibres become shorter and weaker.
ADVANTAGES
-Makes use of recycled papers - a sustainable resource.
-Well suited for bulk grades of paper (newsprint, tissue, board packaging)
DISADVATNAGES
-Cannot always be recycled as the pulp loses quality and more virgin pulp will need to be added.
-Doesn't save any more energy than other methods.
-Requires processing and additives to achieve a good quality.
