Highlights
•
Duckweed has been tested as feedstock for biogas production.
•
Higher cellulose and low lignin content of duckweed indicate its potential for higher biogas production.
•
Volatile matter of duckweed (84.24 ± 0.2%) with a lignin content of 12.2%, which is very promising for biogas production.
•
Combination of duckweed and cattle dung @ 50:50 facilitated highest biogas production.
