Chemical Pulping


	Chemical Pulping
	Advantages High quality wood pulp produced with longer, stronger fibrs that contain fewer inpurities Produces 'chlorine-free' disposable products Waste lignin from the process can be burnt as a fuel oil substitute, often supplying power to the national grid or steam to local domestic heating plants	Disadvantages Lower yeild than mechanical pulping, as the lignin has not completely dissolved and seperated from the fibres No chemical pulp is produced in the UK, therefore is has to be imported
