Hardide is committed to reducing its emissions to the environment in every aspect. In the selection of equipment at Hardide’s new facility in Bicester, special attention was paid to identifying equipment and methods of waste treatment that reduce the environmental impact, use less material, or both. As a result, items of old but serviceable machinery have been replaced at greater financial cost but with much-enhanced environmental performance.
In our new UK facility, we have eliminated the use of natural gas, and all electricity is now supplied from a renewable REGO-certified (Renewable Energy Guarantees Origin) source. The only use of natural gas is at our US facility in Martinsville where it is used for workspace heating.
In creating our US facility we now coat parts for North American-based customers in the US, rather than in the UK, thereby avoiding double freight transits across the Atlantic and considerable emissions of CO2.
Hardide’s products greatly increase the life of customers’ components by reducing wear and enhancing corrosion resistance, with customer and test reports of over a hundredfold increase in useful operating life. They also help improve efficiency and provide further benefits to end-users that include reduced downtime and extended service intervals. Each of these features bring environmental benefits.
Hardide’s coatings are non-toxic and are environmentally compliant. Used to replace hard chrome plating (HCP) on components, they eliminate the health hazard that the production of HCP presents and reduce the amount of toxic chrome sludge in landfills, which pose threats to both soil and groundwater. Hardide can be used instead of high- velocity oxy-fuel (HVOF) thermal spray coatings, which can contain cobalt. The use of cobalt is currently under review by the European Chemicals Agency and is thought likely to be restricted or possibly banned in the future.

CO2 Emissions
Any water used in the coating process is filtered, stored in interception tanks and before discharged to drain, is analysed to ensure compliance with permitted limits. All gaseous emissions are passed through a series of wet scrubbers to ensure that there are no harmful emissions to atmosphere. The resulting wastewater is treated and tested as above. Regular testing of discharges to drain are taken and analysed by the local water companies.
Water usage
Environmental Management Systems
Our site in Bicester is accredited to the requirements of ISO 14001:2015 and subjected to regular internal and external auditing. The Martinsville facility complies with the requirements of the local Public Service Authority (PSA) and the State of Virginia Department of Environmental Quality (VDEQ). Regular auditing and sampling of discharges to drain takes place.
Most customer parts for coating arrive in packaging which is reused to return the parts to the customer. Only a small amount of waste is sent to landfill and consists of such items as general office waste, non-reusable packaging and plastic containers from suppliers.
Metal residue resulting from the coating process and any metal used in masking and tooling of the products is segregated and sold to metal recycling companies.
