What are the advantages and disadvantages of sanitary landfills and incineration?

Incineration plays a vital role in making waste management easier and more efficient. Incineration can burn up to 90% of the total waste generated and sometimes even more. However, landfills only allow organic decomposition without making much difference, and non-organic waste keeps accumulating.
