Municipal Solid Waste Management

Solid waste management all over world is looked as major challenge to civil bodies. Pune corporation has taken initiatives to collect, segregate and treat solid waste and system for handling around 1600 MT / day is operative. Composting, biogas and inert waste recycle are present mode of treatment. Praj Industries limited, Pune has taken the activity further to noticeable level and can integrate overall waste management activities so that from biodegradables, biodiesel, bio CNG, fuel ethanol and liquid manure can be safely produced. No waste is left over. Biodegradable solid waste in Pune has potential to generate Biodiesel-18 to 20 MT/ day, Fuel ethanol-7 to 9 M3/ day, BioCNG-10 to 12 MT/ day and in addition 1100 to 1200 M3 liquid manure / day can be produced. These energy rich compounds can generate electricity, run vehicles and maintain solid fertility. One has to look scientifically in the optimization of collection and segregation from the point where waste generates. (C) 2016 Published by Elsevier B.V.
