Poorly designed or poorly managed landfills can create a number of adverse environmental impacts such as wind-blown litter, attraction of vermin, and generation of liquid leachate . Another common product of landfills is gas (mostly composed of  methane and  carbon dioxide), which is produced as organic waste breaks down anaerobically.

15. 2.) Incineration Incineration is a disposal method in which solid organic wastes are subjected to combustion so as to convert them into residue and gaseous products.   Combustion in an incinerator is not always perfect and there have been concerns about pollutants in gaseous emissions from incinerator stacks.  Particular concern has focused on some very persistent organics  which may be created which may have serious environmental consequences. 9/29/2013 Waste Disposal Management 15

16. 3.) Water Treatment Plants Sewage treatment is the process of removing contaminants from wastewater and household sewage, both runoff (effluents), domestic, commercial and institutional . Using advanced technology it is now possible to re-use sewage effluent for drinking water, although  Singapore is the only country to implement such technology on a production scale in its production of  ’NEWater’. The objective of sewage treatment is to produce a disposable effluent without causing harm to the surrounding environment, and prevent pollution. 9/29/2013 Waste Disposal Management 16
