Milling combines several mechanical stresses, such as compression, friction, impact, and shear. The combination of these stresses reduce the particle size, crystallinity, and degree of polymerisation, making the biowaste more accessible for further processing. However, milling is energy intensive and has a high capital cost. The required energy can be reduced by combining milling with other processes.<ref>{{Cite journal|title=Ball milling as an important pretreatment technique in lignocellulose biorefineries: a review|year=2021-08-12|author=Yalew Woldeamanuel Sitotaw, Nigus G.
