Session Information
Straw briquettes – a 2nd generation raw material – that effectively can boost your
biogas production and replace 1st generation silage and similar raw
materials.
Local regulations are aimed at increasing use of cereal straws and limiting energy
crops in order to render biogas operations more climate, energy, and
environmentally benign. Raw materials such as corn silage is being phased out
and the only possible replacement is agricultural crop residues such as wheat
straw. So far it has been virtually impossible to use wheat straw in
significant quantities in biogas operations due to the hydrophobic, porous, and
recalcitrant properties of raw straw. However, briquetted straw offers the
opportunity to effectively introduce and co-digest straw briquettes in biogas
operations, and obtain a high and stable gas yield. This session will introduce
a full concept of using straw in biogas operations.
