Abstract: Organic solid waste represents 50% of the Municipal Solid Waste (MSW) composition in Palestine. MSW in the West Bank (WB) are managed by municipalities, Local Governmental Units (LGUs), and Joint Service Councils (JSCs). MSW are collected and transferred to the existing four landfills along the WB, there are no waste separation or recycling in Palestine except small projects and enterprises. The collected MSW reaches the landfills as a mixed wastes with the composition of metal, paper, glass, plastic, and organic wastes. The current organic waste treatment in Palestinian territories is represented by composting and biogas generation, the small pilot projects of composting that have been implemented facing problems related to quality, competition, and financing. Biogas production from organic solid wastes is also limited and concentrated in producing biogas from animals manure. New proposals have been discussed regarding solid waste incineration in the field of Waste To Energy (WTE) projects, except the composting and bioenergy there are no another treatment for organic MSW in the WB. This study ensures about the importance of the concept of waste separation at source, and to adapt the concept of WTE operations. Due to the high moisture content and high organic proportion in the MSW; bio-drying processes are valuable as a pretreatment stage for organic waste treatment. This study also highlights on the Refuse Derive Fuel (RDF) as a product of bio-drying processes that could help in organic MSW treatment.

Abstract: Assimilative capacity of air environment in Dolvi, Maharashtra was evaluated. AERMOD was applied to pin down the spatial distribution of PM10 and PM2.5 concentrations. The baseline air quality was delineated, and it was found that PM10 and PM2.5 concentrations were beyond National Ambient Air Quality Standards (NAAQS) in every season. The major contribution to these particulates were from fugitive emissions i.e. mainly resuspended dust from vehicles and highway construction. As the plant had planned for expansion, spatial distribution of PM10 and PM2.5 was estimated at 5 MTPA and 10 MTPA. It was found that existing air environment in Dolvi region was very poor, however, the results of dispersion model showed that modifications in technology at 5 MTPA reduces PM 10 and PM2.5 concentration in ambient environment and at design estimations of 10 MTPA the concentrations are within standards. It was also found that paving of external and internal roads the PM 10 concentrations will reduce by 70% compared to existing scenario but due to movement of vehicles on external road PM 10 will continue to be high at some locations in the region. The estimation of VC in region showed that it does not have enough assimilative capacity in month of February and April and in month of October region has less pollution potential as higher VC values 15300 m2/s were present. This study also revealed that VC values are an important parameter for understanding the natural capacity of region for its existing air quality.

Abstract: The socio-economic development activities are aimed to improve the quality of life of the inhabitants along with industrial growth of the region. The development activity proposing expansion or new construction is anticipated to affect environment and hence any ecosystem existing in the vicinity of development activity needs to be assessed. In this study, an attempt has been made to assess the changes in existing ecosystem services due to expansion of industry and construction activities in the Dolvi region. For assessing the carrying capacity of region in such scenario indicators like NDVI, NDWI, Vegetation NDWI and forest ecosystem services such as carbon stock are estimated using geospatial techniques. To account for the possibility and effect of development on forest ecosystem, remote sensing and field analysis was carried out to estimate the status of indicators along with carbon sequestration and sink potential for the region. The NDVI value of 0.87 show healthy vegetation existing in the region. The NDWI has indicated the presence of water indicating region is not under water stress. From the current biomass estimation, the study region shows presence of forest which has biomass as high as 8 Mg/ha at terrestrial vegetation and 5 Mg/ha at mangrove vegetation. This biomass is a result of carbon sequestered in the region as 84.7 Mg/ha. The study confirmed that region has high Carbon stock with sink potential to absorb emissions from the development activities including construction and expansion of the industry in the region.q
