Closure plan of an old landfill in Kampong Chhnang, Cambodia: a study on closing a dumpsite in a developing country.

Abstract

The thesis focuses on the comprehensive closure plan for an old landfill, commissioned by Polarix Consulting Oy. The primary objective of the study was to develop a systematic plan encompassing the relocation of accumulated waste, sealing procedures, and the implementation of essential infrastructure to an old landfill in Cambodia. This involved designing a cover structure (capping) for the landfill, devising a water management strategy (without purification), establishing a protocol for landfill gas management, and ensuring physical barriers to restrict public access to the area. Qualitative research methods were employed throughout the study to assess the environmental impact and feasibility of various closure techniques. The process involved extensive literature review, combining preliminary data and reports from the client, drawing details sections and a layout of the capping by using AutoCAD design program and on-site evaluations to understand the specific challenges and requirements of the project in a developing country. Overall, the thesis contributes to the body of knowledge in landfill closure practices and offers practical recommendations for stakeholders involved in similar projects. By prioritizing environmental protection and sustainable development, the study benefits not only the client but also the broader community by ensuring the safe and responsible management of waste disposal sites.
