Design and Operation of Semi-Aerobic Landfill

Introduction

Solid waste management is a systematic practice of waste generation storage, collection, transport, treatment and disposal (Agamuthu, 2010). Sanitary landfill is one of the important methods for solid waste disposal in waste management system. Even though there are more advance disposal methods have been developed, the sanitary landfill remains as an ideal method for developing country (Idris & Hassan, 2004). The sanitary landfill is a final disposal method that treats and restores the organic portions of the waste to the nature which emphasizing the technical aspects like siting, design, operation and long-term environmental addeddment (Hans & Ramke 2001).

Unlike open dumpsite, the sanitary landfill is designed to deal with leachate, landfill gas and odor management. The collected wastes are handled at a disposal facility that is designed and operated at a constraint of public health and environment protection. The primary purpose of landfill site is to implement final disposal of the waste with minimum environmental impact. Besides, the sanitary landfill system can be classified based on decomposition process employed. Table 1 describes the characteristics of the landfill types.
