Glanua: Sustainable Water and Wastewater Solutions for a Greener Future

What is the Glanua Project?

Glanua is all about making the planet cleaner and greener. This innovative company focuses on designing, building, operating, and maintaining critical water and wastewater infrastructure across the UK and Ireland. With a passion for tackling today’s environmental challenges, Glanua delivers sustainable and decarbonised engineering solutions that serve both municipal and industrial sectors. Their expertise covers everything from design and commissioning to operation and maintenance, always pushing the boundaries of innovation in water and wastewater management.

Main Benefits of Glanua’s Approach

Here’s what sets Glanua apart:

• Industry leader in water and wastewater solutions across the UK and Ireland
• Focus on sustainability, innovation, and engineering excellence
• Customised solutions that help clients comply with environmental regulations
• Collaboration with clients and partners to stay ahead of technological trends
• Commitment to reducing ecological footprints through efficient effluent treatment
• Miniaturised Fluidised Bed Combustion (FBC) technology converting low-value organic waste into heat and power
• Local, low-carbon waste disposal solutions reducing transport and equipment size
• Production of high-quality ash rich in phosphorus and potassium, adding value to waste

Innovation at the Core

Innovation isn’t just a buzzword for Glanua—it’s the heartbeat of their work. Their miniaturised Fluidised Bed Combustion (FBC) technology is a game-changer. Originally developed to convert poultry manure into energy within a closed-loop system, this unique combustion tech now tackles a wide range of organic wastes. Think municipal and industrial wastewater sludges, meat and bone meal from rendering plants, organic fines from municipal solid waste, and anaerobic digester residues—materials that traditional boilers struggle to burn. The miniaturisation aspect is key here, shrinking what used to be massive incinerators down to a much smaller, more efficient scale.

Protecting Our Environment

Glanua’s commitment to the environment goes beyond just compliance. They work hand-in-hand with manufacturing, industrial, and municipal clients to treat effluents before they hit the environment. Their customised solutions don’t just meet regulations—they promote sustainable practices and actively reduce ecological footprints. By managing waste locally and efficiently, they help cut down on transport emissions and minimize the environmental impact of waste disposal.

Building a Circular Economy

At the heart of Glanua’s mission is the drive to build a truly circular economy. Their continuous research and development efforts focus on refining processes that turn waste into valuable resources. The high-quality ash produced by their combustion technology, rich in phosphorus and potassium, is a perfect example of this. Instead of waste ending up in landfills, it becomes a resource that feeds back into the environment, closing the loop and supporting sustainable agriculture and industry.

Project Impact on Sustainable Development Goals (SDGs)

• SDG 6: Clean Water and Sanitation – through advanced wastewater treatment solutions
• SDG 7: Affordable and Clean Energy – by converting organic waste into heat and power
• SDG 9: Industry, Innovation, and Infrastructure – via cutting-edge engineering and technology
• SDG 11: Sustainable Cities and Communities – supporting municipal waste management
• SDG 12: Responsible Consumption and Production – promoting circular economy principles
• SDG 13: Climate Action – reducing carbon footprint with local, low-carbon waste solutions
• SDG 15: Life on Land – protecting ecosystems by managing effluents responsibly

The Evolution of Glanua

Back in 2023, BHSL Group rebranded to Glanua Group Limited, sharpening its focus on sustainable engineering solutions for water and wastewater infrastructure across Ireland and the UK. This wasn’t just a name change—it was a fresh, integrated identity combining the strengths of its subsidiaries. Glan Agua Ltd became Glanua Ireland, MEIC Ltd transformed into Glanua Civils, Hydro International is now Glanua Industrial, and Glan Agua UK rebranded as Glanua UK. Together, these entities form a powerhouse dedicated to innovation, sustainability, and environmental stewardship.

What Glanua actually does

Glanua is a water, wastewater, and organic waste engineering group based in Loughrea, Ireland. The company was known as BHSL until a 2023 rebrand that unified it with its sister operations, Glan Agua and Hydro International, under one name.

Where Glanua shows up

• Municipal water infrastructure: delivered the Kerry Central Regional Water Treatment Plant and the Co. Cavan Wastewater Treatment Plant.
• Technology partners: Marches Biogas serves as its UK sales and service partner for its waste-to-energy technology.

Proof, not just claims

Why this belongs on a sustainability directory

Glanua connects to SDG6 (Clean Water and Sanitation) by engineering the drinking water and wastewater infrastructure for municipalities, and to SDG12 (Responsible Consumption and Production) through its organic waste-to-energy technology, originally developed under the BHSL brand.
