| description | Rice straw is one of the abundant renewable resources in the world. Until now, open
field burning remains a common practice in many Asian countries for the final disposal
of rice straw. The emitted pollutants from open burning of rice straw may cause adverse
impact on visibility, human health, and regional air quality. Bio-transformation of rice
straw to value products is an economical and environmental friendly solution for this
problem. However, one of the main problems in rice straw transformation is its nonbiodegradability.
The bio-oxidation rate of hydrocarbon compounds in solid state
increases after such compounds transform into solution forms. Similarly, the composting
of lignocellulose materials significantly enhances under thermophilic conditions.
Therefore, this study focuses on time reduction of the rice straw composting process by
using thermochemical pretreatment and operation under thermophilic conditions. This
study investigates the operational condition of the thermochemical pretreatment process,
optimize the thermochemical pretreatment, and determine the influence of thermophilic
condition on the composting of pretreated rice straw. The objectives of this research are
for optimization of thermochemical pretreatment process, studying the effect of
pretreatment process on the stability, maturity and enhancing of rice straw composting
process. The influence of mesophilic and thermophilic conditions was also
investigated. |
