Sammendrag
Proper disposal of municipal solid waste of Lahore is one of the major challenges for responsible
waste management authorities. Various studies reveal that about 50 to 70% of the generated
waste is collected in Lahore while the rest of the waste lies in the street, walkways and in vacant
plots. The collected waste is dumped in the open and uncontrolled landfills without any energy
recovery. The present study is a literature review study where an attempt is made to find out
sustainable solution for the disposal of municipal organic waste of Lahore. In the present study it
is found out that biogas production from the municipal organic waste is a sustainable source of
handling the waste. Hence, the biogas production will also help to achieve sustainable
development in Lahore due to reducing the gap of demand and supply of electricity shortfall
through renewable energy sources (biogas), greenhouse gas emission reduction substituting the
fossil fuel and receiving the economic benefits from biogas.
Biogas production from municipal solid waste Lahore will improve environmental quality of the
surrounding by reducing GHG emission and control the leachate pollution. A rough estimate of
the study shows that if 100% of the generated municipal organic waste of Lahore is collected and
utilized for biogas production this can produce 352,745.96 m3 biogas/ day. The produced biogas
can be utilized for electricity production or upgraded biogas can be used in the vehicles which
substitutes the fossil fuel. Of this produce biogas 884MWh electricity can be generated with 35%
electric conversion efficiency while 50% of the biogas energy can be utilized for cooling or
heating the buildings. In addition to these 18,234,387.4 tons CO2 equivalent/year can be avoided
due to changing of current improper waste disposal system to biogas and the substitution of
electricity and chemical fertilizer. From the economic point of view biogas production from the
municipal organic waste of Lahore can generate revenue of US$ 844.34 billion /year due to the
substitution of fossil fuel, chemical fertilizer replacement with digestates and through carbon
credit scheme.
