Abstract
Households with all their activities produce waste which can be a source of GHG emissions if not managed properly. Reducing waste from its source is one of the ways to reduce GHG emissions. In Bandung Regency, one of the ways to reduce household waste is by running the Waste Bank program. Research is needed to find out how much the reduction of GHG emissions from waste management in the Waste Bank. This study used a combination of quantitative and qualitative methods with descriptive analysis including IPCC method to estimate GHG emission reductions from waste management and in-depth interview with the operators in one of the Master Waste Banks (Bank Sampah Induk) in Bandung Regency, Y Waste Bank. The results showed that the potential GHG emission reductions from Y Waste Bank reached 0.016 Gg CH4 or equivalent to 401.273 tons of CO2eq, reducing GHG emissions from total household waste in Bandung Regency by 0.0007 %. Program and technology innovations and also assistance for customers or fostered groups are expected to be able to increase the quantity of waste managed at the Y Waste Bank up to the household level so that it can give higher contribution in reducing GHG emissions in Bandung Regency.
Highlights
Climate change expert’s consensus believe that the global warming is a natural phenomenon that accelerated by human activities, especially after the industrial revolution occurred [1,2,3]
Analysis was focused on efforts from the waste bank operators to improve their waste management that contributes to greenhouse gases (GHGs) emission reduction
GHG emission calculation method from Intergovernmental Panel on Climate Change (IPCC), the emission value result is greatly influenced by the type of waste management which has been carried out because it will affect the value of the methane correction emission factor used in the calculation [15]
Summary
Climate change expert’s consensus believe that the global warming is a natural phenomenon that accelerated by human activities, especially after the industrial revolution occurred [1,2,3]. One of the main causes of the earth's average temperature increase or scientifically known as global warming is caused by greenhouse gases (GHGs) [4,5]. The waste management is one of human activities that potentially emits the most significant greenhouse gasses (GHGs) such as Carbon Dioxide (CO2) and Methane (CH4) during its process. Reducing household waste from its source is a practical strategy to cope with solid waste problems. This strategy has been carried out in Bandung Regency, especially to support the campaign of Bandung Regency waste-free by 2020. One of the pivot programs of this strategy is the Waste Bank, which focused on reducing household inorganics waste [10]
