“…Also biomass pellets burn clean and are highly preferable to coal due to no negative impact on health and air quality [10]. With the availability of agro waste in large quantities in the country, the pellet production potential in Nepal is estimated at 11.21 metric ton with the generation of 83.5 Peta joule energy [11] .…”

Pellets are densified biomass fuel compatible for household as well as industrial use. Pellets can be potentially used as an alternative fuel source in many medium, small and micro enterprises (MSME) such as dairy, dyeing, laundry, khoa making, pickle making, yogurt making, soap making enterprises etc. in Nepal. Despite of the presence of large number of such industries and abundant biomass resources, production and application of pellets as a fuel source is almost non-existent in Nepal. Hence, to assess the benefits of using pellets as alternative fuel, an applied research of pellets application was carried out in a dyeing industry. Energy, environment and economic performances of the dyeing industry was compared between the baseline scenario of utilizing sawdust and wood chips mixture in loose form with that of non-carbonized pellets application as an alternative fuel. Results showed decrease in specific energy consumption by 6% on utilizing non-carbonized pellets compared to baseline. In terms of the environmental performance, emission of CO decreased from 100 Mg/L to 10 Mg/L and CO2 emission decreased from 7.5% to 4%. Similarly, suspended particulate matter (SPM) emission decreased from 37.4 mg/Nm3 to 14.8 mg/Nm3 but the negligible increment of NO2 emission was observed. However, emission of SO2 increased significantly from 3.3μgm/m3 to 33.7μgm/m3. High Sulphur content was found in the pellet which could be from the lubrication used in the pellet machine, but this could not be confirmed. The economic analysis revealed that the energy cost was almost twice with pellet application which was mainly because of the higher cost of imported pellets. If the production could be initiated in Nepal, utilizing the abundantly available local biomass resources, the cost could be considerably lowered thus making use of such fuel economically feasible.

“…It is therefore vital to address this issue by promoting alternate ways of disposing the crop residues like in-situ utilization as mulch, using it as raw materials for industries like brick kilns, paper production, mushroom cultivation, etc. and for alternative energy production like bio-briquette, pellets [34,35].…”

Determinants of crop residue burning practice in the Terai region of Nepal

2021

View full text Add to dashboard Cite

The open burning of agricultural crop residue is a key environmental issue facing the Hindu Kush Himalaya region, the Indo-Gangetic plain in particular. There is a varying intensity in the incidence of open agricultural burning in this region, and multiple drivers that determine why farmers in this region decide to burn their crop residues. While there have been research studies conducted for other countries in the region, research into the determinants of crop-burning in the Nepalese context is missing. Using primary data from a survey of 388 farming households across three districts of the Nepal Terai―Nawalparasi, Rupandehi and Kapilvastu―applying a recursive bivariate probit model, this study seeks to find out what drives the Nepalese farmers to burn their crop residue instead of using them in a sustainable manner and suggest policy recommendations for mitigation. Our findings show that the major determining factors that influence the farmers’ behavior in Nepal are livestock ownership, combine harvester use and awareness level of the farmers. While the effects of crop residue burning is transboundary in nature, the mitigation measures require to be region specific. Based on the findings, the study proposes raising livestock, using technology like Happy Seeders or upgrade the combine harvesters, raising awareness and changing perception of farmers, and promoting alternative uses of crop residue as viable mitigation measures.
