IQE has a unique opportunity as a leading material solutions provider to develop technologies that support a sustainable world.

We are committed to minimising the environmental impact of our operations and have a robust environmental management system in place to ensure compliance with regulations and encourage waste reduction. Achieving a high level of environmental performance is a priority for IQE, as we recognise that acting responsibly is not just good for the world, but actively contributes to the success of our business.

IQE encourages all employees to reduce their impact on the environment, including through reducing waste, recycling, restricting unnecessary travel, saving water and reducing energy usage.

Environmental Policy

IQE’s policy for conducting business in an environmentally responsible manner is as follows:

  • We fully integrate environmental considerations into the business planning and decision-making processes;
  • Compliance obligations are identified and our operations must be conducted in accordance with these obligations;
  • We validate our fulfilment of compliance obligations by means of documented periodic review;
  • We employ best practice to reduce the environmental impact of our operations, prevent pollution, minimise waste and maximise the efficient use of energy and resources to protect the environment;
  • We will work with companies throughout IQE's supply chain to help minimise their environmental impacts;
  • We continually improve our environmental management system and its performance by setting measurable objectives and reviewing them on a regular basis;
  • We provide suitable information and training to all employees, and interested parties to ensure that the aims of the environmental management system are achieved;
  • Appropriate resources will be made available to ensure this policy can be implemented.

In addition, each of our sites will supplement this policy to meet local requirements.

Compliance with Legislation

Compliance with environmental legislation is critical to our global businesses and we adhere to the laws of the jurisdictions in which we operate. To ensure we are meeting our regulatory requirements we employ appropriately qualified Environmental, Health & Safety professionals, reporting to the Chief Operating Officer, and these EHS professionals have access to third-party professional advisors as required.

Additionally, IQE maintains membership of a number of professional bodies which provide a good source of reference and support, enabling it to keep up-to-date with continually evolving legislation. This includes regular updates from the British Standards Institution, Institute of Environmental Management and Assessment in the UK, the Institute of Occupational Safety and Health (IOSH), the US National Safety Council, the US National Fire Protection Agency, Semiconductor Environmental Health and Safety Association, and the US Federal Register.

Environmental Management System

IQE’s Environmental Management System (EMS) is designed to the ISO 14001:2015 standard, which provides a structure that enables us to meet Environmental Policy commitments and requirements for environmental compliance. The ISO 14001:2015 standard is broadly separated into EMS sections including: Context of the organisation, leadership, planning, support, operation, performance evaluation, and improvement.

All of IQE’s operating facilities are third-party certified to meet the ISO 14001:2015 standard. This is a global standard for environmental management which was developed to help organisations reduce their environmental impact and provide a framework for the continual improvement of environmental management practices. IQE successfully completed independent third-party audits of our ISO 14001 compliance in 2019 with no material deficiencies recorded.

Waste, Water, Soil and Air Management

At each of our global sites IQE operates continuous improvement programmes to reduce waste and to recycle and re-use wherever practicable. Currently each of our locations recycles plastics, steel, aluminium, paper, cardboard and process by-products where the opportunity to do so safely exists.

IQE also closely monitors the consumption of electricity, gas and water at all facilities, and looks for opportunities to improve energy efficiencies for new facilities, existing facilities, and facility expansions. Examples include:

  • The new Newport Mega Foundry designed and built from 2018 to 2019. The Newport facility was built to the highest technical standards with emphasis on energy-saving features, engineering controls, and air emission controls.
  • The existing US based North Carolina MBE manufacturing facility incorporates state-of-the-art engineering and energy-savings controls that are designed into its cleanrooms, wastewater management, and air emission controls.
  • Facility expansions in Massachusetts (USA) and Hsinchu (Taiwan) from 2018 to 2019 were designed and built with the latest technologies in energy savings, hazardous material handling safety, and air emission controls.

Additionally, IQE seeks minimise all GHG emissions and has targeted environmental improvement programs as part of ISO14001 to reduce carbon dioxide emissions and the depletion of natural resources as well as conserve water usage, and minimise waste generated. As a Company trading on AIM, a market operated by The London Stock Exchange, the reporting requirements relating to the disclosure of greenhouse gas emissions do not apply to IQE.
