Building a Sustainable Future

Metal Technology realises that a firm commitment to environmental matters is of great importance to a productive and efficient business. Accordingly, we believe that we have a responsibility to work with our suppliers and clients in minimising the environmental effect of our work wherever and whenever the case may arise. We are committed to making a positive impact on the environment through our responsible business practices. Explore the various facets of our sustainability initiatives below.

Target Net Zero

At Metal Technology, we recognize the urgency of addressing climate change. Our commitment to achieving Net Zero emissions is at the forefront of our sustainability goals. We are actively implementing strategies to reduce our carbon footprint across our entire value chain, from supply to production, through to distribution.


Business In The Community (NI) Climate Action Pledge

We are committed to reducing our scope 1 and 2 greenhouse gas emissions by 50% by 2030, as well as measuring and reducing our scope 3 GHG emissions and reporting company-wide GHG emissions on an annual basis. We look forward to working in collaboration with other NI businesses to address the critical issue of climate change.

Metal Technology’s Managing director Calvin Wilson commented :

“We have, for many years, had a strong focus on reducing our carbon footprint, and initially introduced solar panels to reduce our energy consumption in 2014. This has now gathered pace and this year we will introduce an additional 100kW system, which will have the added benefit of battery storage for electricity we are producing but not consuming, with a programme to enhance this further in 2024.

This is in line with our environmental strategy, with all company vehicles ordered from 2022 being fully electric or Hybrid. We have also recently taken delivery of a further 3 electric forklifts which now means our entire fleet of 8 trucks are also fully electric. We have renewed our electricity contract which is from a green energy source, further demonstrating our long-term commitment. All electric lighting within our offices and warehouse facilities have been changed or upgraded to LED. Packaging is also being minimised and sourced from recycled materials.

The introduction of our new Passive House range of windows, doors and curtain walling is testament not just of our processing commitments but also to the built environment. We are excited to be part of the BITC community with so many like-minded companies and are confident in achieving our goals well in advance of our target date. So, let’s collaborate on climate change – it’s our future.”


Low Carbon Aluminium

Our dedication to sustainability extends to our product offerings, with a focus on Low Carbon Aluminium. We leverage advanced technologies and processes to minimize the environmental impact of our aluminium production. Our low-carbon approach ensures that our materials meet the highest industry standards while significantly reducing the carbon intensity associated with their manufacture.

Metal Technology have taken a corporate decision to only procure and supply aluminium profiles that have been manufactured from a low carbon aluminium billet with a maximum carbon footprint of 4.0kgCO2/kg aluminium. The current Global average is 16.7kgCO2/kg aluminium, with a European average of 6.7kgCO2/kg aluminium.
For ultra-low carbon projects we have billets available, offering kgCO2/kg aluminium of 3.0 and 2.3, currently the lowest available in the market.

Please speak to your regional Architectural Advisor for more information on a project specific basis.


The intrinsic qualities of aluminium, its infinite recyclability, strength and lightness, durability and low maintenance qualities mean it is one of the most sustainable building materials that can be used.

Aluminium is the earth’s third most abundant element after oxygen and silicon (ahead of iron).

Aluminium does not emit dust, vapour or particles and is not toxic to touch.

Given its durability and resistance due to applied surface treatments such as anodising or powder coating, aluminium structures need only regular cleaning with neutral detergents followed by rinsing with water.

Aluminium is non-flammable and, when it reaches its melting point in the event of a fire (about 650°C), it gives off no flammable gases or vapours.

Life cycles

Recycling is a valuable asset in the battle against the greenhouse effect. The global aluminium industry has made great strides during the last century to reduce its environmental impact at all stages of the supply chain. Aluminium extraction and refining companies have reduced their energy requirements by almost 70% since 1900.

Aluminium extraction has seen the growing use of hydro-electric energy coupled with a vast increase in aluminium that is recycled. At present more than a third of global aluminium production is from recycled metal, a figure that is growing. Recycled aluminium takes just 5% of the energy needed to produce primary metal with a consequent reduction of 95% in the greenhouse gases produced.

The recycling process is economically attractive and viable. Recycled aluminium meets almost 40% of the demand for the metal in Europe. Between 80%-100% of the material used to produce Metal Technology extrusions is recycled.

Aluminium is infinitely recyclable with no loss of its properties.

The aluminium cycle is a closed life cycle

The Delft University of Technology in the Netherlands has investigated the collection rate of aluminium in buildings. Demolition case studies in six different European countries (France, Germany, Italy, Spain, the Netherlands and the United Kingdom) were carried out and the data collected shows that collection rates are over 95%.

Recycling aluminium windows

As the loss of metal in the remelting process is such a small percentage, and the remelted material keeps the same quality, this allows the same metal to be used in the same product over and over again. (i.e. almost absolute recycling.)

The purpose of recycling is to produce new high quality material from waste and used products in an economical and environmentally friendly manner.

There are generally two kinds of raw material for recycling, process scrap and waste from the aluminium industry.

The process scrap is easy to identify and it has a well known composition, while on the other hand aluminium from used products is much more complex. However, both types of scrap can be processed and recycled to a high standard.

Finishes to the aluminium are simply burned away in the melting process and any noxious gas emissions are collected in efficient fume capture equipment. This gas is burned off providing heat to the furnaces. Non-metallic components end up in the salt slag, and an inert substance skimmed from the molten aluminium is used in the cement industry. Thermal breaks or resin are either mechanically separated or simply burned away in the process. Where aluminium is combined with other metals such as stainless steel screws and fixing lugs, this aluminium is fed into a special furnace that separates the iron thermally (i.e. iron and steel melt at a higher temperature than aluminium and are also heavier. As a result they fall to the base of the furnace, thus ensuring 100% aluminium can be accessed.)

Gasketry must be manually removed from the window as part of the deglazing process. Material is then sent to a rubber recycling plant where it can be re-smelted or ground into granules.

In many of these cases, the stainless steel has suffered little degradation and still contains a high value of the initial alloying elements such as chromium, nickel and molybdenum. This makes it a valuable source of those constituents to the stainless steel producer and a high proportion of material going into the melting furnace is usually recycled.

Metal Technology Aluminium products are 100% recyclable. It is Metal Technology’s aim to continue to develop its recycling theme within the building industry in order to realise its environmental plan for the future.

Environmental Product Declarations

An EPD is a document that is used to demonstrate the environmental impacts of a product and is used to provide data for evaluating green buildings, allowing architects and designers the ability to assess products prior to the inclusion within the building fabric.

Metal Technology has undertaken a third-party accredited Life Cycle Assessment (LCA) of its manufacturing facility, and associated supply chain for its core façade systems – Windows, Doors, and Curtain Walling.

Greenhouse gas emissions

In 2016 we started measuring and monitoring the greenhouse gas emissions that occur because of our activities. We will continue to do this going forward to drive performance improvements and reduce our emissions per tonne of product we sell.

Direct Emissions93.690.387.384.966.381.868.9
Indirect Emissions30.126.525.825.523.721.622.8
Total Emissions123.7116.8113.1110.490.0103.491.7

Solar panel generation

Solar panels installed on our warehouses mean greenhouse gas indirect emissions have been reduced as follows:

Generation (kwh)55592543645913655186578045787057409
Indirect Emissions reduced by (tonne)23191714131211

Waste recycled10.5210.028.669.19.4810.2710.2510.169.4010.2710.14

We record the amount of waste we generate year-on-year. Due to the nature of our products, we recycle the majority of our waste and send only a small proportion to landfill. We are continuously driving ourselves to be more efficient with resources and reduce the amount of waste we are sending to landfill.

We strive to reduce the amount of waste we generate from our activities. Following an internal benchmarking exercise, we decided to benchmark ourselves against our 2016 performance to drive us going forwards.

Waste Best Practice

We have a commitment to apply the waste hierarchy and maximise diversion of waste from landfill. Effective management of all waste streams will be achieved by adhering to the waste regulations. A register of licences for waste carriers is detailed in the Metal Technology environmental management system which is certified to ISO 14001:2015. Performance metrics are also set around minimising waste as far as practicable, and that waste produced is diverted from landfill. As part of its wider waste management strategy Metal Technology monitors and measures the amount of waste that it produces as an organisation in tonnes.

The amount of waste generated can then be derived in terms of kilograms of waste generated per tonne sold. At this moment in time industry benchmarking is not possible.

We have had success with staff engagement with waste reduction activities through promoting behavioural change to encourage office recycling. This also forms part of our supplier evaluation process which we use to engage with our suppliers.


As a company, we use very little water in our production process, with most of our use being for domestic purposes. However, as a company we recognise water is a scarce resource and so understand the importance of conserving water. We therefore measure our water consumption to ensure we are being as efficient as we can.

Our use for 2016 was 13 m3 per employee and in 2017 11.5 m3 2018 to 10.3 m3 2019 11.7 m3, 2020 8.2 m3 and 2021 10.13 m3 and 2022 9.52 m3 .

Water Best Practice

We have a commitment to use water as efficiently as possible. Metal Technology commits to monitor and minimise water usage as far as practicable, given that all water used by Metal Technology is sourced from mains water supplies and thus no water is extracted directly from the source. Water meters are installed allowing Metal Technology to measure domestic water consumption – no water is consumed during the production process. A reduction in water use will be strived for by setting performance metrics around water use, which will monitor and measure domestic water use in litres. The litres of water used per employee can then be derived. Objectives and targets are focused upon minimising use and staff are educated in the efficient use of water in the workplace.


1. We deliver our products both within Northern Ireland and to the UK mainland. We therefore understand that emissions from transport of our product to our customers have potential to cause significant environmental harm. For deliveries within Northern Ireland, we use our own fleet of vehicles, and we use our ISO 14001 certified environmental management system to identify environmental impacts from our fleet. For our deliveries to the UK mainland, we use several third-party hauliers, who we survey to establish how they identify and manage their environmental impacts. We will strive to work with our hauliers to help them meet our environmental ethos and comply with our CSR policy.

2. Through our environmental management system, we have identified our impacts on the environment from transport as emissions of CO2, CO, NOx, particulate matter and other volatile organic compounds (VOCs).

3. To mitigate against our significant environmental impacts, we ensure all our drivers and the drivers of our third-party hauliers are CPC trained in fuel efficient driving techniques. We have upgraded our fleet to lorries with Euro VI emissions class engines to reduce our impact on the environment from vehicular emissions. In addition to this, we also plan routes to ensure deliveries in the same locality can be grouped on the same lorry and we use full loads where possible to minimise our emissions per tonne of product transported. Our hauliers have also been surveyed to understand what actions they take to minimise their environmental impacts, with planning of routes, monitoring of fuel efficiency, and use of Euro VI emissions standards vehicles all tactics employed by our hauliers.

Employment and skills

We recognise the importance of having a skilled workforce to deliver our products. We therefore invest in providing our employees with learning and development opportunities to help them in carrying out their day to day role.

In 2016 we provided a total 524 hours’ worth of training increasing to 536 in 2017, 654 in 2018, 724 in 2019, 741 in 2020, 658 in 2021 and 686 in 2022.

Local Communities

As a responsible organisation, we recognise the importance of giving back to the local community in which we operate as and when we can. We therefore make a number of cash donations throughout the year to a number of good causes.

In 2016, we donated a total of £45,885 to local community and other charitable good causes. In 2017 this figure increased to £61,118 and again in 2018 to £75,061. In 2019 we donated £58,744, 2020 £42,552, 2021 £40,247 and 2022 £56,050.

We also recognise the importance of being a good neighbour and therefore take any community complaints that we might receive very seriously.

In 2016 we received zero community complaints and it is our aim to ensure we continue to achieve zero community complaints going forward. In 2017, 2018, 2019,2020 and 2021 we did not receive any complaints.
