Inadequate management of pyrolysis technique by-products poses health risks
The Central Pollution Control Board (CPCB) has pulled up 270 tyre pyrolysis units in 19 States for employing technology that is polluting and harmful to the health of workers employed.
Tyre pyrolysis refers to a technique of breaking down used tyres in the absence of oxygen. Shredded tyres, at temperatures between 250º C and 500º C, produce liquid oil and gases.
While this is considered a safer technique than burning tyres, pyrolysis leaves fine carbon matter, pyro-gas, oil as residue and the inadequate management of these by-products poses health risks.
