Thorn, Ian; Au, Che.Most pulping operations using the kraft process are net contributors to the electricity grid or use the electricity to run an adjacent paper mill.It is used by itself to form two and three-dimensional shapes and collages.

The individual fibres in this sample are around 10 m in diameter.Mechanical pulps have rather short fibres, thus producing weak paper.

With almost twice the yield as chemical pulping, mechanical pulps is often cheaper.See also Notes Hogben, Lancelot.
