Summary
Clinical Waste Incinerator operated by Stericycle (SRCL) Ltd and located at the Royal Oldham Hospital. The plant consists of a single stream, rated at 850 kilograms per hour or 7,446 tonnes per annum of solid wastes[1]. The Primary Chamber operates the rotary kiln design to provide good mixing of the waste coupled to sufficient retention time to burn the wastes to a high quality ash[1].
Plant
Waste is loaded mechanically into the Primary Chamber using a hydraulic lift and tip arrangement, to avoid any manual handling of the waste[1]. The rotating action of the rotary kiln provides good mixing of the waste, exposing fresh surfaces to combustion conditions[1]. The combustion process is operated slightly in the sub-stoichiometric or starved air mode to produce volatile gases to fuel the Secondary Chamber while providing good burnout of the fixed carbon in the waste to produce bottom ash. The bottom ash is discharged from the end of the rotary kiln into an ash quench system to cool it rapidly, and from the ash quench pit it is discharged into storage skips. The skips of bottom ash are taken to a licensed landfill site for disposal as Non-Hazardous Waste[1].
The combustion gases produced in the Primary Chamber then pass into the Secondary Chamber, which operates at a minimum temperature of 850°C during start-up using Non-Hazardous Waste; and at a minimum temperature of 1000°C when Hazardous Waste may be loaded[1]. The Secondary Chamber provides a minimum of two seconds residence time under oxygen-rich conditions to combust any Carbon Monoxide and volatile organic compounds produced in the Primary Chamber[1].
The hot gases then pass through a boiler and dilution air system, which reduce the temperature from above 1000°C to around 160°C, before the gases pass on to the flue gas treatment system[1]. The query SELECT "updated" FROM "db_ea"."ea_ew_in" WHERE epr='ZP3230XC' LIMIT 1 is invalid (Error : SSL SYSCALL error: EOF detected
Function: EDConnectorRdbms::fetch Query: SELECT "updated" FROM "db_ea"."ea_ew_in" WHERE epr='ZP3230XC' LIMIT 1 ).Error: Could not connect to database (Cannot access the database: Unable to connect to PostgreSQL server: connection to server at "10.106.0.2", port 5432 failed: FATAL: the database system is in recovery mode).Error: Could not connect to database (Cannot access the database: Unable to connect to PostgreSQL server: connection to server at "10.106.0.2", port 5432 failed: FATAL: the database system is in recovery mode).
Waste Tonnage, By Origin
The table shows a list of the Waste for the Permit ZP3230XC, that has arrived into sites as reported to the Regulator and then publicised in their reported statistics. The Data used is from the most recent returns. The total reported tonnage arriving at the site was: Expression error: Unexpected < operator.t.
Where this tonnage exceeds that reported in year of the corresponding annual report, this may be due to the following reasons:
- Tonnage may have been received but not incinerated, i.e. the material is held pending incineration (the operator return to the EA reports as received whereas the annual report focuses on when the waste is incinerated.)
- Material may have been received into the site but treated in some other way than incineration.
- Material may have been received on the but transferred out of site for disposal/treatment at another site rather than incineration on the site.
