Rice Field Residues
Abstract:
Emissions from open burning of rice residues are becoming an environmental problem of concern due
to its impacts, especially on air quality. The objective of this study is to investigate the optimum
utilization of unused rice field residues to reduce agricultural open burning emissions using field survey
and questionnaire survey in order to evaluate which emission reduction alternative would be the most
beneficial to the environmental in terms of air quality and global warming.
The research methodology was composed of 3 parts:
1) Determination of the amount of unused rice field residues by using statistical and physical properties
modeling tools.
2) Estimation of air pollutants and GHG emissions from open burning of unused rice field residues
based on 2006 IPCC guidelines.
3) Estimation of the amount of rice field residues usable for possible emissions reduction options and
their associated emissions ofair pollutants and GHG based on 2006 IPCC guidelines.
This study found the amount of unused residue that subjected to open bum is about 30.8+-7.47 Mt
(26%+-6.3% of generated rice residue) included l6.8+-4.07 Mt of stubble and 14.0+-3.38 Mt of straw. At
the average combustion rate 0.18+-0.03 for stubble and 0.68+-0.06, the amount of residue consumed by
fire will be about 11.3+-2.19 Mt (15%+-2.9% of generated rice residue) comprised 2.4+-0.49 Mt of
stubble and 8.9+-1.70 Mt of straw. Burning of 11.3+-2.l9 Mt contributes GHG as CO2 13.35+-2.595 Mt,
CH4 0.003+-0.0006 Mt and N20 0.0008+-0.0001 Mt and pollutant as CO 1.5+-0.29 Mt, NOx
0.035+-0.0007 Mt, PM2.5 0.3l+-0.060 Mt, PM10 0.15+-O.028 Mt, and black carbon 0.008+-O.0015 Mt.
To reduce emissions from rice residue open burning, the 3 utilization of 16.8+-4.07 Mt of unusedstubble
and l4.0+-3.38 Mt of unused-straw scenarios were purposed and compared emission with base
line scenario for validation the optimized utilization. The base line scenario covered open burning
unused residue, rice cultivation in the burned field with incorporation in the pre-cultivation season, and
lignite power production. 3 scenarios for mitigation emission from burning of unused residue included,
(1) zero open burning by agricultural purpose (all of unused straw incorporated into the soil), (2) zero
open burning by energy purpose (all of unused straw used for power production), and (3) zero open
burning by energy and agricultural purpose (unused straw in the high of power and provincial capacity
is used for energy purpose, the otherwise is used for agricultural purpose). Zero open burning by energy
purpose (scenario 2) was the good option in term of non-CO2 emissions reduction (0.76 MtCO2eq
reductions), the largest of net emission reduction (44.7 MtCO2eq) and also the outcome as power 1,221-1,998
MW. Zero open burning by agricultural purpose (scenario 1) mitigated the open burning
emission but enhanced emission especially in the group of non-CO2 from the rice cultivation activity.
Stop open burning by agricultural and energy purpose (scenario 3) was the good option in term of CO2
emission reduction (37.1 MtCO2 reductions) and implementation.
So, the emission mitigation option of rice residue open burning is to manage the unused rice residue.
The optimum utilization of unused residue in terms of environmental friendliness and implementation
for agricultural and energy purposes.
