Birdsall Leather and Crafts
“The Birdsall Leather and Craft tannery produces approximately 20,000 litres of effluent every week. Apart from odour issues, we were well in excess of our Trade Waste discharge limits with high Chromium, Phosphate, Sulphate, BOD, oil and grease levels. We were disposing of the sludge in landfill but the clay lining of the landfill started to degrade.
With a combination of reagents that can be re-used and with no capital expenditure, Virotec made the sludge inert so it could be disposed of as general rather than hazardous waste at a much lesser cost. The smell is barely noticeable and employee and customer complaints have significantly reduced.
What we liked about Virotec was that they did the lot – technology, design, engineering, application, monitoring and liaison with the regulatory authorities. As we are now well below our discharge limits we have one less worry.”
