Short Lived Climate Pollutants (SLCP) avoidance and reduction approaches in municipal solid waste (MSW) management Janya Sang-Arun Senior policy researcher Sustainable Consumption and Production Group Institute for Global Environmental Strategies (IGES)
IGES-SCP SLCP avoidance What is the major SLCP from MSW management? • Methane – greenhouse gas – Degradation of organic matter under anaerobic condition (no oxygen) open dumping, landfill - Incomplete combustion of waste and fossil fuels • Black carbon – black smoke – Incomplete combustion (low heat) of waste under open burning and some types of incineration – Incomplete combustion of fossil fuels Janya Sang-Arun IGES | http://www.iges.or.jp CCAC-MSWI, 23-24 Feb 2014, Surabaya 2
IGES-SCP SLCP avoidance How to avoid and reduce methane emission? 1) Avoided open dumping and landfill of organic waste 1.1) Use for animal feed 1.2) Composting and use for soil amendment 1.3) Producing biogas for energy use 1.4) Pre-treatment before landfilling – mechanical biological treatment (MBT) 1.5) Incineration with advanced and well controlled incinerators 1.6) Others 2) Captured landfill gas for energy use or flaring Janya Sang-Arun IGES | http://www.iges.or.jp CCAC-MSWI, 23-24 Feb 2014, Surabaya 3
IGES-SCP SLCP avoidance How to avoid and reduce black carbon emissions? 1) Avoided open burning of waste 1.1) Prohibit/Stop open burning 1.2) Separation of recycle materials before disposal to dumpsite that has open burning 2) Reduced waste transportation by heavy fuels 2.1) Reducing waste generation (reduce, reuse) 2.2) Enhancing residents to treat their own waste – household composting, etc. 2.3) Changing type of fossil fuels use (e.g. diesel NGV) Janya Sang-Arun IGES | http://www.iges.or.jp CCAC-MSWI, 23-24 Feb 2014, Surabaya 4

IGES-SCP SLCP avoidance • Change of fossil fuel use : change from diesel to NGV Phitsanulok, Thailand Janya Sang-Arun IGES | http://www.iges.or.jp CCAC-MSWI, 23-24 Feb 2014, Surabaya 14
IGES-SCP SLCP avoidance Conclusion • There are many SLCP avoidance and reduction practices in Asia. • Remaining questions are: – How we can sustain & scale-up these practices? – How we can improve the management & operation? – How to select the most appropriate technologies for our cities? – How we can systematically account our efforts on SLCP avoidance and reduction? – Etc. We can work together to find solution for these challenges under the CCAC-MSWI . Janya Sang-Arun IGES | http://www.iges.or.jp CCAC-MSWI, 23-24 Feb 2014, Surabaya 15
