. provides a 90% yield from teh pulpwood as it uses the whole of the log except for the bark.
. investment costs for mechincal pulp mills are realtively low in comparsion with other types of mill.
. well suited for 'bulk' grades of paper; i.e newsprint and packaging boards.
. can be bleached to produce higher value-added products.
. lower strength characteristics than softwood chemical pulps
. paper can 'yellow' when exposed to bright lights due to high lighin content.
. higher quailty wood pulp produced with longer, stronger fibres that contain fewer impurities.
. produces 'chlorine-free' disposable products.
. waste lighin from the process can be burnt as a fuel oil substitue, often supplying power to the national grid or steam to local domestic heating plants.
. lower yeild than mechanical methods as the lighin is completely dissolved and separated from the fibres.
. no chemical pulp is produced in the UK, therefore it must be imported
. makes use of recycled papers, which are a sustainable resource.
. well suited fro 'bulk' grades of paper; i.e. newsprint, tissue and packaging boards.
. cannot be recylced indefinite;y as pulp loses quailty - virgin pulp needs to be added.
. does not save any more ebergy in processing than other methods
. requires considerable processnig and additives to produce good-quailty paper.
