4.2 Cellulosic materials

The structural integrity of non-woody (i.e. herbaceous) plants is provided mainly by cellulose, which is a major component of the straw and other supporting tissues of all the major food crops.

The most common cellulosic bioenergy crop for temperate climates is the tall grass miscanthus.

  • bracken
  • Gunnera
  • kelp
