Summary
Clinical Waste Incinerator operated by University Hospitals Plymouth NHS Trust and located adjacent to Derriford Hospital. The incinerator currently processes 3,500 tonnes of non hazardous waste and hazardous wastes most of which is clinical waste[1].
Plant[2]
The incinerator has a design capacity of 650kg/h with a typical operating capacity of ~510kg/h. The incinerator is fitted with air pollution control comprising of lime injection (to control emissions of sulphur dioxide and hydrogen chloride) and activated carbon (to control emissions of heavy metals and dioxins). There is also a high efficiency bag filtration system for the removal of particulate matter. There is a secondary combustion chamber that provides the required residence time of more than 2 seconds at a temperature of at least 850°C and 1000°C for cytotoxic wastes. Natural gas is used to support the combustion and to maintain the secondary temperatures.
Emissions to air are discharged via a 70-metre stack. There is an energy recovery system, and the incinerator supplies hot water to the adjacent hospital. Solid wastes produced are primary bottom ash and residues from the air pollution control system.
Waste Tonnage, By Origin
The table shows a list of the Waste for the Permit GP3236AX, that has arrived into sites as reported to the Regulator and then publicised in their reported statistics. The Data was last updated on October 2023. The total reported tonnage arriving at the site was: 3,549.65t. 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.
