Construction and Operations

When will the plant be built?
It is anticipated that construction will commence in 2021 and be operational by 2024. Once construction starts, we expect the build and commissioning phases will take approximately three years from start to finish.
What is the operational life of the facility?

Today, modern energy-from-waste plants, such as the proposed 3Rs facility, can operate for thirty (30) years or more.
Will the facility operate 24/7?

Yes, the facility will operate 24/7, but waste deliveries will not be made 24/7.  Vehicles will only be allowed to enter the plant during normal working hours which will be controlled by the planning permission. Most of the plant’s operations will be carried out inside the building, which prevents and mitigates the amount of noise that could be heard externally.
Will the facility be noisy?
Noise has been very carefully considered and assessed using computer modelling of the proposed building and process equipment. The planning permission will set limits for the noise emitted by the plant and this will be monitored and enforced by both Horsham District Council Environmental Health Department and the Environment Agency.
Will the facility smell and attract vermin?
No. Waste that cannot be recycled will be delivered by road to the tipping hall into the facility where it will be immediately tipped into a bunker within the building. Importantly, as the building operates under a negative air pressure, this draws in air and prevents odours from escaping externally. The facility will deploy vermin control, which will be subject to strict monitoring by the Government’s Environment Agency.
What happens to the residues it produces?

After combustion, the volume of waste is reduced by 90%, leaving an inert ash containing metals.  The other residue produced by the plant will be that from the gas clean-up system. The ash will be non-hazardous and will be taken offsite to an ash recycling facility where it will be turned into an aggregate and used in applications such as road base.

The residues from the gas clean-up process will be alkaline as it will consist mostly of lime. This will be stored in a sealed silo and collected from the site by vacuum tanker. It will then be taken to a licensed processing plant where it will be used to neutralise acidic chemicals or turned into a rock-like aggregate and recycled.
Will there be any recycling from the back end of the facility?

Yes. After combustion has taken place at the facility, we are able to recover metals from the remaining ash for recycling. The metals will be removed from the residual bottom ash for recycling and the ash itself will be recycled into a replacement aggregate material... Recycling metal from EfW facilities avoids the energy spent in smelting new metals and recovers valuable natural resources that would have otherwise been lost in landfills.
