• The cost
of straw collection ranged
from US$12 to US$18 per ton
of straw in the MD, accounting for 10–20%
of the total investment cost
of biogas or mushroom production; net profits of mushroom production was US$123 (±14) per ton
of straw used.
This study illustrated the feasibility of the mechanization of rice
straw collection. Despite fossil fuel consumption in mechanization
resulting in GHGE, mechanized rice straw collection can help avoid
in-field burning, produce feedstock for further sustainable processing,
and add value to rice production.
