ii. PLC based auto activation of bypass arrangements for bypassing the pyro gas from reactor to primary oil tank connected to various condensers, uncondensed gas collection tank and flaring system in case of blocking/chocking of outlet vent inside the reactor or direct bypass for flaring iii. PLC based system for control of temperature and pressure inside the reactor iv. PLC based gas sensors connected with sirens (hooters) in case of release of gases (Methane and Carbon monoxide) v. Unloading and bagging of carbon black powder jointly through mechanical and manual means with minimal spillage and fugitive emission vi. Suction hood over the gate of reactor and water sprinkling system for prevention of fugitive emission during unloading of carbon black, opening of the gate and unloading steel scrap.

vi. Existing Batch Tyre Pyrolysis Plants need additional features like PLC based control arrangement, by pass arrangement for pyro gas, installation of gas sensors, pressure, temperature gauges at reactor & storage tank, alarm system, facility for flaring of entire pyro gas during emergency, arrangement for re-circulation of pyro gas for reactor's heating, suction hoods over the gate of reactor, sprinkler system for control of fugitives and mechanized arrangement for unloading of carbon black powder and arrangement of nitrogen purging etc. to meet the environmental concerns.

7.0 RECOMMENDATIONS OR THE STUDY ON ADEQUACY OF TYRE PYROLYSIS PLANTS TO MEET ENVIRONMENTAL CONCERNS i. All the existing batch Tyre Pyrolysis Plants to install additional features like PLC based control arrangement, bypass arrangement for pyro gas from reactor door to primary condenser, installation of gas sensors, pressure, temperature gauges at reactor & storage tank, alarm system, flaring of entire pyro gas during emergency, arrangement for re-circulation of pyro gas for reactor's heating, provision for flaring of pyro gas, suction hoods over the gate of reactor and carbon black powder bagging area, water sprinkler system and mechanized arrangement for removal of carbon black powder and steel scrap and arrangement of Nitrogen(N2) purging.

8. Applicants have stated that presence of gas sensors, pressure and temperature gauges at reactor are a mandatory part of safety and environmental concerns and the same have been violated by respondent 5 in operations of its industrial unit.

9. CPCB has also issued an updated version of SOP dated 16.01.2024 for re-cycling of waste tyres scrap for recovery of Tyre Pyrolysis oil, Pyro gas and Char in tyre Pyrolysis oil units and the copy of the said document is on record as annexure at page 101 of the paper book.
