are landfills a solution to garbage disposal problem of country state advantages disadvantages of it paste pictures
Answers
Answer:
A landfill is an engineered pit, in which layers of solid waste are filled, compacted and covered for final disposal. It is lined at the bottom to prevent groundwater pollution. Engineered landfills consist of a lined bottom; a leachate collection and treatment system; groundwater monitoring; gas extraction (the gas is flared or used for energy production) and a cap system. The capacity is planned and the site is chosen based on an environmental risk assessment study (UNEP 2002). There are also landfills specially designed to encourage anaerobic biodegradation of the organic fraction of the waste for biogas production by monitoring the oxygen conditions and moisture content. Landfills need expert design as well as skilled operators and a proper management to guarantee their functionality.
Advantages
Effective disposal method if managed well
Sanitary disposal method if managed effectively
Energy production and fast degradation if designed as a bioreactor landfill
Disadvantages
Fills up quickly if waste is not reduced and reusable waste is not collected separately and recycled
A reasonably large area is required
Risk of groundwater contamination if not sealed correctly or the liner system is damaged
High costs for high-tech landfills
If not managed well, there is a risk of the landfill degenerating into an open dump
Once the landfill site is shut down O&M and monitoring must continue for the following 50 to 100 years
