Road chiefs have reiterated their objections to a controversial waste energy plant in the Norfolk countryside, branding transport routes “inadequate”. 

The highways department at County Hall has restated its case against an anaerobic digester plant in Bressingham, near Diss.  

The plant uses organic waste and crops – such as manure or maize – to create biomethane that can be used to produce power. 

Deal Farm Biogas, the company behind the plans, has proposed a series of ‘passing places’ for vehicles to overtake lorries going to and from the site. 

But Highways officers at County Hall said the need for 37 expanded sections of road over 2.8miles “only acts to demonstrate the inadequacy of the route”. 

They added: “There are significant issues with regard to the proposed improvements even if they were considered appropriate as there is no guarantee the applicant could implement them.” 

A spokeswoman for Deal Farm Biogas has previously said the Bressingham farm was the ideal site because it is where the feedstock is produced and stored. 

The company argues this will lead to a reduction of 400 two-way movements each year. 

A decision on the application is expected to be made later this month.
