Developers want to increase the amount of material which will be processed by a new waste plant.

But while that means more lorries visiting the site, they will do so via new access road.

Earlier this year GMT Biogas and Mickram won an appeal after plans for an anaerobic digestor on the outskirts of King's Lynn were refused.

It wanted to build a plant processing 14,000 tonnes of beet pulp, maize and animal slurry on land off Cross Bank Road.

But people living on the narrow road objected, because lorries serving the plant would be using it.

Now GMT wants to increase the plant's production to 19,000 tonnes of beet, maize and straw.

But it is also proposing to build a new access road to the site from Estuary Road, meaning vehicles will not need to use Cross Bank Road.

West Norfolk councillors are being recommended to approve the plans when they meet on Monday.

A report to the planning committee says: "Clearly Members need to consider the fallback position in regards to the planning history of

this site, in their deliberations.

"There is an extant permission for a 14,000 tonne biomass/slurry anaerobic digester permission that was granted in April of this year on appeal.

"Looking at the main issues in turn, firstly, the visual impact of AD plant has already been deemed acceptable, and its visual impact has changed little from the appeal decision.

"Although the route has changed from that previously consented at appeal, and there are an extra 425 HGVs involved in the overall process, the traffic implications upon Estuary Road are deemed to be acceptable to the Highways Officer as Estuary Road is wide, has footpaths and is served by a signalised junction.

"Turning to amenity issues, the EHO officers have no objection in terms of noise and odour in respect to the construction of the plant and the operational phase of the development subject to conditions."

When operational, the plant will supply biogas and heat to neighbouring businesses DOW and KL Technologies. The government inspector who upheld the appeal said the plant could be built providing contracts for the supply of heat and electricity were agreed before building work begins.
