Energy rich, but hard to break down

Grasses contain a lot of lignocellulose. They owe their rigid structure to this fibrous and hard to break down material. However, lignocellulose is very energy rich which makes it an attractive feedstock for the production of bio-energy. However it’s a challenge to make this energy available. Due to the poor degradability of lignocellulose anaerobic digestion is difficult, making it economically less profitable.
