ANNOUNCEMENTS
Urban areas are emerging population hub with increased population densities and are considered to be significant Greenhouse gas (GHG) emitters. It is crucially identified that quantification of greenhouse gases is a must prerequisite. The study aims to quantify the amount of GHG release from urban local bodies (ULBs) Andhra Pradesh state targeting waste management sector as the key thrust area with key indicators including methane generation from SWDS and nitrous oxide emissions from biological treatment of MSW generated. The study aims to quantify methane emissions from solid waste disposal sites (SWDS) for bulk waste and different compositions of waste. Nitrous oxide emissions from biological treatment of organic component of waste. The study analyses the potential of different mitigation measures on methane and nitrous oxide emissions from SWDS and biological treatment of waste in Andhra Pradesh.
The impacts of mitigation measures have been identified on the basis of reduction potential in respective GHG. For this purpose, a comparative study is done between the BAU scenario(business as usual) and ALT scenario (alternative scenario) for ULBs of Andhra Pradesh. The study analyses various alternative scenarios for the horizon years i.e. 2020, 2030 and 2040. These scenarios have been compared to the base year 2015. The key findings that emerge from the study includes maximum methane emissions from SWDS is due to food waste deposited in the landfills and during biological treatment of waste the wet weight component account less nitrous oxide emissions as compared to the dry weight component. The alternative scenarios are the combinations of various policy interventions and action plan statements (national or state level). Therefore on the basis of Alt scenarios for years 2030 and 2040, consecutive reduction in GHG emission levels are observed.
