Roberts Waste Disposal is a third generation family business operating a successful waste transfer station in Bridgwater, Somerset.
Operating a fleet of skip lorries and hook loaders from an extremely successful transfer station in Bridgwater, the company has recently experienced a significant increase in the amount of waste been processed.
To process and recycle a large proportion of the incoming material a new waste material sorting plant was commissioned, designed, manufactured and installed by DUO Manufacturing from their Somerset works.
The Roberts waste sorting system was designed to specific criteria and depending on the type, condition and bulk density of the feed material the plant is designed to handle up to 100 tph and will separate the feed material into 6 grades.
With all tip waste deposited into the transfer station, large items are sorted and removed, the remainder of the waste is then loaded into a feed hopper and transferred via a 4 metre x 1.2 metre vibrating tray feeder into a 2.4 metre x 5.6 metre rotating trommel screen.
The 0-40 mm material in the feed is screened out and deposited into the bay below the trommel for removal by a loading shovel, the + 40 material is then transferred via 1200mm wide x 15.2 metre long link conveyor into the 4 - station picking house.
Picked waste is discharged into 2 skips situated beneath the picking chutes with a third skip being fed directly from the 1200mm wide by 25 metre long picking belt.
The system also incorporates a blowing unit for the removal of further light waste and a permanent self cleaning magnet, overband separator to remove the ferrous material from the oversize material which is deposited via a stainless steel chute into the ferrous material bay.
Constructed of heavy-duty material the new plant is designed for ease of maintenance and operation, and has provided Roberts Waste with the ability to recycle a larger proportion of incoming material with scrap, plasterboard, clean wood, green waste and cardboard being recycled. Any general waste that cannot be recycled is transported to the local landfill site at Walpole.
Finally, the resulting clean hardcore from the plant is removed to another adjacent company site where it is crushed and used for secondary surface materials.
Beccy Roberts - Director, commented, "The plant has been very successful as it has allowed us to recycle a large proportion of our waste and we will strive to recycle more as time passes. Unfortunately there is a shortage of sites for other wastes such as plastics and glass in the South West; ideally we could recycle more if we had more local opportunities"
