5] plastics boxes, bags , shopping container.
*chemical disposal of hazardous waste-[2016-2018]
1]The chemical disposal hazardous waste by chemical include ion exchange, oxidation, reduction and neutralization.
2] The most desirableis to reduce quantity of waste at its surface to recycle the materialfor other productive use.
3]For solve problems of HWD there will always need for treatment and for storage and disposal of some amount of hwd.
4]The method is used for disposal is biologically is called land fillingor farming.
5] In technique the waste is carefully mix with surface soil on suitable track of land microbes that can metabolize the waste may be added among nutrient.
6]In some cases genetically engineered bacteria is used .some commen type of tempore storage for hazardous liquid waste is open pit or holding called lagoons ponds
*solid waste treatment as sanitary landfills --[2018-19]
1] sanitary landfill of solid waste is little better than open dump , actually sanitary land fill means an instalation wheare a satisfactory solid waste disposal operation is being carreid out in accordance with recognised procedure.
2] A mathod of disposing of solid waste on land without creating nuisanve of hazardous waste to public helth.
3]The smallest waste to the smallest perticular area to redused it to smallest valume and cover it with layer of earth.

* How radioactive waste from thermal power plant affect envoirment-
1]Neuclear power plant used the uranium as fuel. The process of mining uranium realease high amount of co2 in envoirment .
2] when the nuclear power plant are made or built it involve the transfer of co2 inti the envoirment wich causes pollution.
3]uranium wich is use as fuel is remain radioactive in the envoirment for thousand of year and it dangerous for our helth
4] There is the envoirmenral threat due to radioactive decay . Destruction caused by radioactive material because of emultion of hazardous ionizing rasiation like beta , gama , alpha rays exist in envoirment.
5]Thease radiation metal seriously affect and even destroy plant and animal life , the extent of damage or danger posed to envoirment depemd on radioactive material concentration.
