ENVIRONMENT (emissions & waste)

1.        How much ash will this process create (fly ash and bottom ash)? What will you do with the bottom ash that is collected?

The combustion of the wood provides a residual of only 3% of ash.  About 80% of this is bottom ash (around 20 tonnes per day).  The bottom ash will be collected in sealed silos and is non hazardous so can be used for several purposes including use as a fertiliser filler.  GPL will seek customers for this ash nearer the time when the plant starts to operate. The top ash is deemed hazardous and will thus be sent to a proficient waste contractor for appropriate disposal.

2.        What kind of filtration system will the plant employ to minimise the fly ash?

The plant will use activated carbon to capture the small particles in the exhaust, and then this in turn is captured with the fly or top ash in a bag filtration system.

3.        What will be coming out of your chimneys?

Emissions will be almost entirely hot air.  We will have a full emissions monitoring system to control the emission of pollutants and almost all airborne particles will be captured by the filtration system.

4.        Will the emissions be clean?
 
The plant will be operated well within the operational emissions limits set by the Environment Agency. .

5.        Won’t the burning of wood inevitably generate smoke and dust?

The bag filtration system captures the smoke and dust normally associated with wood fires

6.        Will you need to build a cooling tower/s as part of the development?

A cooling system will certainly be required.  However, as we are close to the river, GPTVL believes that river cooling is the best available option and we will work with the EA to ensure the plant has no adverse effect on the river

7.        How high would the plant be? 

The main building will be the boiler house, which needs to be about 50m high.  The tallest structure will be the stack (chimney), which needs to be about 70m high.
