Incineration is a general term that applies to burning material, usually waste.  It mostly applied to the plants that were built many years ago that just reduced the waste to an ash with no energy recovery - therefore reducing the volume of waste then sent to landfill.  

Today, with the exception of some hazardous waste treatment plants, all energy from waste thermal treatment plants recover the energy in waste (exported as electricity or heat), and the ash is recycled.  Modern energy from waste plants are therefore no longer incinerators.

The burning process is referred to as combustion, which is the oxidation of the material being burnt in air.  With Gasification, the material being treated is heated to above 700°C without enough oxygen present to enable it to burn.  This causes the molecular structure of the material to break down and produces a gas called synthesis gas.  This enables the gas to be used in various ways.  One way is to burn the gas, and in a gasification energy from waste plant, it is the syngas that is burnt, not the waste itself.  Gasification and incineration are, therefore quite different. 

All thermal processes create emissions, but the plant cleans them before releasing them to the atmosphere so they are not harmful.  This process is controlled strictly by the regulations and the local authorities and the Environment Agency in England and Wales, and SEPA in Scotland monitor all energy from waste plants to ensure they do not emit substances in quantities harmful to human health.  

Before a plant can be operated, it has to obtain an environmental permit which states the maximum level of emissions the plant can emit.  If the plant exceeds any of the limits it must report it to the regulatory authority and take corrective action. If it fails to satisfy the authorities, the plant will be closed down.

No not only will Drenl be looking at current waste management companies and local authorities to take waste from the local area meaning the same waste trucks will remain in the area just with a different end destination; but waste will be both sorted and processed all on site avoiding multiple journeys, in collections, delivering, processing and so on.

No. The plant is designed with fast acting roller shutter doors which will be closed when vehicles are inside the building to unload waste; keeping both noise and smell emissions to a minimum. These doors will remain closed other than vehicle access.

Approximately 200 jobs will be created during construction and 60 permanent jobs.

Where possible we will look to hire locally.

No.  Drenl has specific requirements of its suppliers to which each will need to agree before delivering to the site.  We will be able to consider most commercial companies, but the general public will not be allowed to deliver to the sites unless special provisions are made to enable them to do so.

Yes, we will primarily be looking to utilise waste in the local area.
