The Margam Green Energy Biomass Plant is a 40MW electricity power station utilising chipped wood waste as fuel otherwise destined for landfill. When fully operational the project will use around 300,000 tonnes of waste wood from nearby regions.
The plant is located on land off Harbour Way (A4241), near Margam in South Wales, in an area designated for commercial and industrial development. Built on a 3.98 hectares site the buildings are surrounded by a 6209m2 (66,834ft2) concreted yard plus asphalt access roads and car park.
Hauraton supplied three types of channel to meet the rigorous specifications for surface drainage of the main concreted yard surrounding the plant, weighbridges and car park.
Three sizes of RECYFIX® HICAP® high capacity channels were installed in the yard. 3 metres of HICAP® 1000, 303 metres of HICAP® 2000 and 255 metre of HICAP® 3000. The total water capacity of the HICAP® channels was just over 20,390 litres. By installing this system, the channel runs were kept to a minimum so saving on installation costs and future maintenance. Factory fitted with 14mm slotted ductile iron inlets, the channels comply with a loading Class of F900 so can easily take the weight of a HGV fully laden with wood chips. Importantly, once installed the complete system is highly resilient to the twisting forces imposed by the laden vehicles.
42 metres of FASERFIX® SUPER 150 channels with Class F900 ductile iron 20mm gratings were installed around the two weighbridges. The FASERFIX® channel component is made from the company’s Fibre Reinforced Concrete with galvanised steel angle housings moulded into the top edges of the channel during production. This specification is highly resistant to extreme loads and constant dynamic forces and was found to be ideal for the weighbridge application. The FASERFIX® gratings are secured by SIDE-LOCK® patented boltless system. The system allows gratings to be installed and later, removed quickly. Once a grating is positioned over the channel, foot pressure is simply applied. A loud click is then heard which confirms it is securely locked onto the channel. The grating is removed using a large screwdriver inserted into a discreet leverage point. This feature is particularly useful where channels need to be cleaned out at regularly.
Finally, 39 metres of RECYFIX® PRO 100 Type 75mm factory fitted with FIBRETEC® heel-safe gratings were installed in the car park. The FIBRETEC® grating, moulded from a fibre strengthened Polyamide (PA-GF) and allows loadings up to Class C250 (BSEN 1433)
All he RECYFIX® channel components specified for the project are made from 100 per cent recycled Polypropylene (PP) derived from post consumer and post industrial sources.
Hauraton Project Manager, Cat Jones comments about the project,
“We are pleased to have worked closely with the contractor, Interserve, on this large project. Working on a call of schedule with precise delivery dates we managed to ensure delivery’s arrived on the specified dates. On site project management was essential to ensure the smooth running of this project”
