A. Karna et al., RECYCLING LIFE-CYCLE ANALYSIS OF NEWSPRINT - A EUROPEAN VIEW - IT MAYBE BEST TO USE ONP FOR ENERGY RECOVERY, Pulp & paper Canada, 95(11), 1994, pp. 38-45
Life cycle assessment (LCA) is a method for making a comprehensive eva
luation of all the material and energy resources needed for a product
or service during its physical life, as well as the emissions involved
. At KCL, a dedicated computer program has been developed for LCA purp
oses. One of its first applications concerns newsprint. The analysis i
s based on systematically collected data. Two cases of maximized maxim
ized collection rate are studied, the first involving greater paper re
-use and the second energy recovery from waste paper. These are compar
ed with the reference condition in Europe (Germany) in 1990. The LCA i
nventory calculations show that, if the landfilling rate is to be redu
ced, it is ecologically preferable to use more waste paper for energy
recovery rather than to maximize recycling. Besides carbon dioxide bal
ance, several other emission parameters (though not all) support this
conclusion.
