Shaping a Sustainable Future Together

Developing our new, market-leading sustainability strategy

Glanua has been at the forefront of implementing innovative sustainable solutions for our valued clients. As we expand our footprint, we recognise the need to do more to safeguard future generations’ well-being.

In support of our ongoing commitment towards sustainability, we are partnering with Earthshine Group – a leading consultancy with offices in Dublin and Copenhagen – in developing a new, market-leading sustainability strategy, covering all dimensions of the sustainability agenda, which will be fully integrated within our business strategy, operations and our entire value chain, including our valued customers, suppliers and stakeholders.

By developing an integrated approach, we will be able to take a proactive stance in managing all sustainability-related business risks and opportunities, while delivering improved sustainability impacts and long-term value. We will also be working towards decoupling of emissions from Glanua’s business growth trajectory.

Our new strategy will pave the way towards Glanua being a leader for sustainability in the water industry, delivering a significant range of benefits:

First and foremost – positive action to address the global climate crisis.

Improved impacts for our customers and suppliers.

Enhanced social value and community wealth.

De-risk business performance and future earnings potential.

Full compliance with regulations and standards.

Improved utilisation of natural resources and development of a circular economy.

Improved ESG performance and long-term value.

Eco-efficiency cost savings withe reduced energy, resources and waste.

Enable responsible growth (decoupling).

A major contribution to the UN SDGs.

Leading the Way in Sustainable Solutions

Nature Based Solutions

In full bloom

As part of our commitment to promoting a sustainable and biodiverse environment, Glanua planted a wildflower meadow at Gorey RWSS.

Bug Hotels

Glanua collaborate with local community group, Cloyne Irish Men’s Sheds Association on building and installing ‘bug hotels’ to promote biodiversity in the Lower Aghada Pump Station and Whitegate Waste Water Treatment Plant.

Renewable Energy

Glanua completed the installation of 230 solar panels at the Thurles RWSS on behalf of Uisce Éireann. The predicted annual energy yield from the system was 83,264 kWh per year of renewable energy, giving a CO2 Offset per annum of 40 tonnes. This system provides up to 40% of the site’s energy demand in the summer months. In 2023, Glanua commenced a Nationwide Solar Installation programme for Uisce Éireann.

As part of our ongoing commitment to sustainability, we’re actively working on defining our Science-Based Targets (SBT).

This process involves rigorous analysis and collaboration with our employees, clients and supply chain to ensure our sustainability goals align with our emissions targets. Our Science-Based Targets will be independently verified and we invite you to check back regularly on this page for updates.

Glanua and the
circular economy

Our vision is to be a leader in unlocking the full potential of bioresources and creating a sustainable circular economy for the clients and sectors we serve. Innovation and the circular economy are embedded in our group DNA having developed a patented Fluidised Bed Combustion (FBC) Technology for the agri-sector. This advanced technology reliably converts manure into heat, electricity and other valuable by-products. We aim to build on our technical expertise and grounding in the principles of the circular economy by expanding our turnkey offering and utilising our Design, Build, Operate and Maintain capability in the sectors we serve.

Our projects make a real difference.
