Guidelines for Site Selection for Landfills for Solid Waste
Decision about design period, it is recommended that neither too long nor too small should be selected. For example, 60 years is considered as too long for landfills, while 10 years as too small. Thirty years design period looks appropriate; however, expert stakeholders may decide with appropriate flexibility.
Sanitary Landfills Vs. Dump Sites
Sanitary landfills are solid waste disposal sites which are properly planned and developed utilizing engineering principles to ensure environmental protection and better quality of life for human being in the surrounding regions; while, dump sites (or dumps) are randomly available places where waste is simply thrown with owners’ permission
Requirements of Solid Waste Disposal Sites
Better planning (based on proper estimation of waste generation rates, population, changes in generation rates and population, diversion factors etc.), proper design and construction (size/ capacity according to requirements, arrangements for leachate and gases recovery, cover requirements, and liners etc.), and continuous
Importance of Solid Waste Collection
The collection efficiency of Municipal Solid Waste varies by national income and by region. In developing countries like Pakistan, the collection services make up the bulk of a municipality’s SWM budget (as high as 80 to 90% in many cases leaving less for other components of the SWM services), yet collection rates tend to be low (40-65% in South Asian
Types of Solid Waste Collection Systems
For the successful waste minimization programs, the waste must be collected appropriately and be transported to the recycling and recovery facilities or disposal areas. There must be efficient waste collection methods and good programs for waste collection because they affect the success of waste management programs significantly.
