Plant Description and Design

Summary of Operational Processes and Procedures

The installation provides a sustainable method of waste disposal and recovery for the whole of the North

Staffordshire conurbation, comprising the districts of Stoke-on- Trent, Newcastle under Lyme, Staffordshire

Moorlands the northern area of Stafford and limited quantities from East Staffordshire, Leicestershire and

Derbyshire, which would usually be taken to landfill.

With two combustion lines operating with a combined capacity of up to 24 tonnes per hour, the facility is able to

process a maximum of around 210,000 tonnes of waste per year, providing an effective alternative for sending

the waste to landfill.

Heat produced during the incineration process is converted to electrical energy by generating steam in high-

pressure boilers and expanding the steam through a steam turbine. When operating at full load, the plant will

typically generate around 14.2 MW of electricity and, after satisfying its own power needs, exports approximately

12 MW of electricity to the grid.

The Plant is regulated under the terms of a Permit issued by the Environment Agency (reference QP3234SX)

which contains conditions to ensure that the requirements of the Waste Incineration Directive are incorporated

and will be met.

MES Environmental operates all of its sites under an Integrated Management System certified to ISO

14001:2015 (environmental management), ISO 9001:2015 (quality management), and ISO 18001:2007 (health

and safety management). The company also maintains the globally recognised RoSPA Gold standard award,

all of which helps to ensure that the company operates responsibly, safely, and efficiently, with regard to all of its

operations.

In terms of plant operation, the incineration processes have been designed against the background of a detailed

assessment of the prevailing environmental conditions at the site location, and are based upon the Best

Available Technology (BAT) as detailed both in the original Authorisation application and the application for the

Permit issued under the Pollution Prevention and Control (England and Wales) Regulations. These include, but

are not limited to, the following:

• Well proven process plant developed specifically for incineration of municipal solid wastes

• Efficient, comprehensive process control and monitoring systems to ensure optimum conditions for complete

combustion of the wastes and to minimise emissions from the processes

• Operations confined within buildings under slight negative pressure in order to contain and minimise emissions

such as dust and odour

• Qualified and experienced operating and maintenance personnel to implement procedures to ensure that the

required high standards are maintained. Operating and Maintenance Procedures are established according to

an internationally recognised system of quality assurance

• Multi-stage high efficiency flue gas cleaning systems comprising deNOx Selective Non-Catalytic Reduction

(SNCR) for the removal of oxides of nitrogen, activated carbon and lime semi-dry acid gas scrubbing for

controlling acid gas, dioxins/furans and mercury emissions

• Final stage flue gas abatement for particulate materials using fabric filtration

• Residues from the combustion process and from the flue gas cleaning system disposed of by approved

means, maximising recycling wherever possible

• Waste water from the process is neutralised and recycled as far as is practicable to minimise the quantities

released to sewers

• Provision of bunds or double skinned vessels for storage of fuel and chemicals in order to prevent accidental

and inappropriate discharge to the public sewers and watercourse

Summary of Plant Operations and Maintenance during the reporting year

Summary of Residue Handling for the reporting year

Each of the two units are designed to operate continuously throughout the year, although regular routine

preventative maintenance programmes are in place to ensure performance efficiency is maintained and to

prevent the development of major problems resulting in significant plant outages.

Routine maintenance activities and legal requirements represent the principal reasons for significant outages.

Other stoppages tend to be short-term shutdowns of individual streams, for one or two days, to deal with smaller

scale issues such as tube leaks or minor repair works. Although these are generally relatively small jobs

the time taken to complete is often extended whilst waiting for boilers to cool down before work can commence

and then by the curing time required when bringing the system back up to operating temperatures.

There were two significant improvements made during 2019 at the Stoke-on-Trent EfW plant, namely that the

combustion control of boiler one has been integrated into the plants distributed control system, and the

improvements to the filter bag cleaning system on baghouse two (which was started in 2018) was completed, this

has allowed for constant ‘on-line’ cleaning of the filter giving more stable operating conditions.

In addition to the above, a number of works were undertaken during the planned maintenance outage, which

included;

- Complete strip down and overhaul of the grate on both units

- Inspection and replacement where shown necessary of superheater panels

- Servicing of the soot blowers (unit 1)

- Inspection and service of screw conveyors (unit 1)

- Inspection and repair of the ash conveying system

- Inspection of all boiler fans and motors

There are two main sources of residue that arise from the operation of the plant; Incinerator Bottom ash (IBA)

which includes ferrous metals discharged within the ash), and residues from the flue gas treatment system -

known as Air Pollution Control residue (APCr).

Residues from the flue gas treatment process are discharged into an enclosed system which feed into double-

skinned heavy-duty bags prior to removal from site for controlled treatment and disposal. These residues

account for around 5% of the total weight of all refuse processed by the facility.

The bottom ash produced by the site represents around 10% of the original volume of the refuse processed, and

around 20% of its weight. Bottom ash residues are discharged from the lower end of each grate into a water

filled ash discharger, where it is quenched and then ejected onto a conveyor system. Larger items are screened

out and ferrous metals are removed via magnetic separation.

The resulting material is stored in the storage bunkers prior to removal from site for recycling - the storage

capacity for bottom ash residues and separated ferrous metals is sufficient to ensure 4 days storage. Collections

for delivery to further processing or treatment sites are made on Mondays to Fridays and are scheduled to ensure

sufficient storage capacity is maintained at all times. Collections are available at weekends if operational

conditions require this facility.

Bottom ash is now widely used in the UK and Europe as a substitute for valuable primary aggregate materials in

the construction of roads and embankments. Bottom ash from MES Environmental is currently being

reprocessed, with additional ferrous and trace metals being removed, and the remaining material being further

processed into usable aggregate.

10-minute Reference Periods Daily Reference Periods

Comments :

Environment Agency explanatory note: The 10-minute average ELV is based on the “95th percentile”. In this case this means that

95% of the 10 minute averages in the relevant 24-hour period (i.e. 137) must be below 150 mg/Nm3, and 5% (i.e. 7) are allowed to be

any value above 150 mg/Nm3. Whilst we expect operators to minimise CO emissions at all times, it is perfectly acceptable for the

value of the maximum 10-minute average to be above 150 mg/Nm3, provided the 95th percentile ELV has been met for that period.
