The inventorization was carried out using revised IPCC 1996 and IPCC 2006 guidelines for National greenhouse gas inventory. There were mainly two types of effluents released from industries viz. non-hazardous and hazardous effluents. The study involved three major sources viz. mineral, metal and “others industries”. The mineral industry comprised three cement and one glass unit; metal represented sixteen industries among them eleven were iron and steel producing, two ferroalloy and three aluminium. Other industries comprised four pulp and paper, thirty food and six beverage. A total of 60 industries were randomly selected which produced non-hazardous effluents. The industries which produced hazardous effluents were also categorized under three broad categories viz. mineral, metal and “other industries”. The mineral industry comprised one cement and one glass unit, metal industry included a total of nine industries among them eight were iron and steel producing and one aluminium. “Other industries” had three food industries only. A total of 14 industries were randomly selected which produced non-hazardous effluents. CH4 was the only GHG released by municipal solid waste (MSW). The main sources of MSW were houses, hotels and restaurants, shops, dhabas, schools, colleges, govt. offices and hospitals. The emissions of different GHG’s were estimated by multiplying the amount of effluents in a particular industrial sector with the emission factor associated with the respective gas released per unit activity in industrial sector. The results have revealed that varying concentrations of different greenhouse gases viz. CH4 and N2O were released from the region. 59.82 Gg CH4 and 1238.42 Gg N2O was released from non-hazardous effluents and 0.28 Gg CH4 and 293.13 Gg N2O was released from hazardous effluents. A total of 385166.94 Gg CO2 eq. was emitted from non-hazardous effluents, 90876 Gg CO2 eq. was from hazardous effluents. Municipal solid waste (MSW) emitted 7503 Gg CO2 eq. of methane. Total amount of GHG released was 483545 in BBN region during 2010. N2O was the main industrial GHG released from BBN industrial region, followed by CH4. The increasing accumulation of above GHG’s in the atmosphere will have adverse impacts on regional climate. Hence following management strategies are suggested to mitigate the effects. The strategies are landfill CH4 technologies, waste reduction, re-use and recycling, biorecycling of urban solid waste and developing clean development mechanism (CDM) like opportunities at local level which will help in achieving carbon neutral development of the region.enThesis
