The simplest way to deal with the waste is open dumping. It is inexpensive and convenient for the dumper, but is not generally suitable as it causes air and ground water pollution and encourages rodents and insects which can be a health hazard.
Organic Matter is decomposed by anaerobic bacteria to produce methane, which can be collected and used as a fuel, and hydrogen sulfide and organic acids.
Products formed from nuclear reactors can maintain dangerously high levels of radioactivity for thousands of years. Waste disposal presents a formidable problem because daughter products from the decay process may themselves act as parents for other nuclear reactions.
The site selected for the disposal must safely contain the material for a very long period of time and prevent it from entering the underground water supply.
There is always the problem that land masses may move and the radioactive material escape, the waste is buried in remote places that are geologically stable.
Advantages of incinerating waste:
Reduces volume/stable odour-free residue/ source of energy
expensive to build and operate/can form dioxins/toxic gases/requires energy/adds to greenhouse effect
