InteliCoat Technologies has invested GBP 150,000 in the recently completed upgrade of its Regenerative Thermal Oxidiser system, for the safe removal of essential hazardous materials.

InteliCoat Technologies has invested GBP 150,000 in the recently completed upgrade of its Regenerative Thermal Oxidiser (RTO) system, for the safe removal of essential hazardous materials in line with the Integrated Pollution Prevention and Control (IPPC) directive 96/61/EC and as part of the company's ongoing programme of continuous improvement Increasing regulatory issues concerning the safe and environmentally friendly disposal of hazardous waste have led to a rise in the costs of monitoring and updating compliance in manufacturing practices

By outsourcing processes such as the coating of materials, responsibility for such issues is transferred to specialist coating companies such as InteliCoat, who are obliged to demonstrate expertise in solvent handling and compliance with environmental legislation.

Coating processes often use materials that generate odours and volatile organic compounds (VOCs).

Using high temperature thermal oxidation, InteliCoat's RTO system typically destroys 99% of VOCs and therefore controls emissions as well as minimising the associated odours.

All InteliCoat's product development, scale-up and manufacturing activities are IPPC-regulated to minimise possible impacts on the environment.

The site operates under permits granted by the local authority, which impose strict conditions that must be met in order to control emissions to air, water and land (including disposal of waste), and also to ensure efficient use of energy and control of noise.

Benchmarked Best Available Techniques (BAT) are used to minimise pollution from current activities and ensure that future developments are sustainable in light of likely future legislation.

The precision coating of engineered films is performed on a web, with any solvent emissions routed into the oxidiser during the drying process to prevent atmospheric contamination.

The oxidiser bed media destroys solvent gases on contact, at a rate of up to 60,000m3/h.

Two oxidisers are operated in parallel, which allows the internal pressure to be maintained on a manageable scale and provides security of supply.

Although there have been moves towards aqueous and solvent-free processes in the coating industry, it is likely that the use of solvents will be required for the foreseeable future and so it remains critically important that methods of safe disposal are continuously reviewed and improved.
