Research title Evaluation of Municipal Solid WasteManagement in Ha Long bay ScenarioAnalysis Based on Life CycleAssessmentApproach Supervisor: Presenter: Associate Professor HelmutYabar Hoang Duong
Content Research Objective Concept Methodology Study area Modelling scenarios LCA andresults
1. Research Objectives Analyzing the current situation of MSW management in Ha Long bay area; Proposing and assessing alternative MSW management scenarios in term of environmental and economic aspects;and Finding out suitable places for MSW facilities by using GIS data and national/provincial criteria in term of sustainable development
2. Concept Municipal solid waste (MSW) refers to wastes generated from households, businesses and office; Several different technologies using to treatMSW: Waste biological treatment Material recycling Incineration Landfill
2. Concept (cont.) Life Cycle Assessment (LCA) approach: a system to assess the environmental impact potential related to a product,process Table 1. LCA framework (Source: ISO2006)
3. Study area Located within Quang Ninh province in northeastVietnam; World Heritage Site; Mainly economic activities: mining; tourist; service; and Current situation of solid waste management (2015): Generated 115 thousand tons/year; Collect rate 90%; No official recycling facility; Most of collected waste is disposed at 2 landfill without LFG collection system; Source: Nippon Koei Co., LTD, 2013, Project completionreport The project for Environmental Protection in Halongbay
3. Methodology 1.Collecting secondary data from official sources such as the amount, the composition of the waste; 2. Using LCA model - IWM-II (Integrate waste management II) software to analyze the input and output data of municipal solid waste management in Ha Long bay; and 3. Using Arc GIS software to optimize landfill site selecting.
4. Modelling scenarios by LCA (IWM IIsoftware) Scenario 1 (S-1): Mixed waste collection, unsanitary landfill without LFG collection Informal Recycle Materials Mixed collection Unsanitary landfill without LFG collection
4. Modelling scenarios by LCA (IWM IIsoftware) Scenario 2 (S-2): Mixed waste collection, sanitary landfill with LFG collection Informal Recycle Materials Mixed collection Sanitary landfill with LFG collection
4. Modelling scenarios by LCA (IWM IIsoftware) Scenario 3 (S-3): Separated waste in source, recycling, sanitary landfill with LFG collection, Bio treatment Recycling Materials Separated waste Bio Product/ Energy gasification/Compost Sanitary landfill with LFG collection
4. Modelling scenarios by LCA (IWM IIsoftware) Scenario 4 (S-4): Separated waste in source, recycling, sanitary landfill with LFG collection, Bio treatment, incineration Recycling Materials Separated waste Bio Product/ Energy gasification/Compost Sanitary landfill with LFG collection Energy Incineration
5. Results Table 2. BOD potential Table 1 . GWPpotential Landfill gas collection and recovery or flaring can reduce GWP value compare to S-1 without landfill gas collection Water is polluted by leachate from landfill and recycling in some cases. The water pollution potential reduces from S-1 to S-4 due to the reduction of the waste amount sent to the landfill
