Roy Hatfield Case Study
Dust Suppression In Gypsum Recycling
Challenge:
Established in 1972 Roy Hatfield Ltd are a family owned have gypsum recycler. Their 6-acre processing facility in Rotherham re-processes of over 60’000 tonnes of gypsum waste every year. The plasterboard is processed, separating the plaster core from the paper liner leaving clean paper and clean plaster Every year around 270 million M² of plasterboard product is produced. A WRAP report identified around 1 million tonnes of plasterboard waste is created annually. Out of this waste it is estimated around 300,000 tonnes is sent for reprocessing, that means only 30% is plasterboard is being recycled As of 2010 plasterboard and other high sulphate bearing wastes are no longer allowed in general landfill. Presently the only 2 options for plasterboard waste are to recycle or dispose at a mono-cell landfill site; due to the high costs incurred for these mono-cell sites recycling is becoming the only feasible option. Working with the environment Agency, WRAP and DEFRA Roy Hatfield have developed new standards for processing recycle wastes which have previously been thought of as ‘unrecoverable”.

The Mist-air Solution:
mist-air have worked with Roy Hatfield for over a decade. In 2009 mist-air installed their first two systems for their open-air processing yard. Localised misting manifolds were installed to the feed hoppers and storage doorways to suppress the dust at these generation points. A mist-air Raingun system was also installed to the outside of the buildings to provide suppression for vehicle and wind movement around the yard to prevent dust from being blown off site and migrating to neighbours. In 2017 the mist-air system was extended when other areas were extended to include a new building over their entire outdoor area. mist-air installed roof mounted fan assisted manifolds to suppress the dust from the whole of their process including, vehicle tipping and the mixing process. The wind break provided by the building allowed the mist to be far more effective.
