#### Deciphering lignin heterogeneity in ball milled softwood

The product was ball milled with a Retch PM-400 planetary ball mill. For the ball milling, stainless steel jars and grinding balls were used. The ratio of jar volume (L):grinding balls (kg):sample weight (g) was kept constant for all the samples 1 : 0.8 : 40. The ball milling was performed in 1 h intervals with 30 min interval breaks at 300 rpm.
