One project in Haryana, India is using Mechanical pre-treatment for the Paddy Straw.

Mechanical pre-treatment is the one which I have seen commercially adopted.

Best process to efficiently digest Paddy Straw is dry fermentation using Plug Flow Reactor. Paddy Straw being one of the most dry feedstock for the anaerobic digestion requires huge amount of water for the wet fermentation. Huge amount of water leads to the high energy requirement for the mixing and heating.

Also, there may be White Rot Fungi in stored paddy straw which is very harmful for the methanogens and in wet CSTR, it can affect adversely.
