HA Ilarduya, takes responsibility.

Whether as supplier or consultant, employer or neighbour: We bear responsibility.

With this in mind, we act responsibly towards people and our natural resources.

We carry on intensive research to apply the specialist know-how in foundry chemistry which we have accumulated over many decades of years to new research approaches in the quest of devising even more efficient and environmentally friendly foundry processes together with our customers.

HA Ilarduya firmly trusts and operates in accordance with a global Integrated Management System and a code of conduct in accordance with the best ethical and moral practices.

“We will only be successful if we align the values of our company, our employees, our social and environmental surroundings. We take our responsibilities seriously.”

Environmental responsibility

What does this mean for HA?

Hüttenes-Albertus and its team have been known to the foundry community as specialists in efficient products and processes for many decades.

We prepare for the challenges of tomorrow by:

  • Intensive research in the area of sustainable and environmentally sound binder systems
  • Modern research methods
  • Close cooperation with universities and institutes
  • Extensive investment in new production equipment

HA recognised environmental protection as an opportunity for the foundry industry decades ago. With this in mind, we systematically promote product developments aimed at protecting the environment. We research and develop products that help our customers reduce emissions in their production processes and keep raw materials in circulation. We take appropriate measures to minimise the general environmental impact of our production processes and products, as well as their impacts on our immediate neighbourhood.

Clean Air

From the selection of the right sand to core production, from drying and casting to the regeneration or landfill disposal of used sand:
There are many sources of emissions in any foundry. At the same time, the regulatory requirements for keeping the environment clean are becoming increasingly stringent all over the world. Foundries are therefore increasingly faced with the challenge of reducing emissions. Of course, this must not be at the expense of product quality, productivity or efficiency. There is a need for chemical casting solutions that achieve this balancing act between lower emissions (BTX, CO2, smoke, odour, etc.) and uncompromising performance.

Recycling management

By promoting the reuse of foundry sand and its return to the material cycle, we can help increase sustainability in every sector of the foundry industry.
Recycling has long been common practice and an everyday reality in the foundry industry. Foundries have always recovered and recycled process materials such as metal and sand which are in turn used to produce moulding materials and cast products. It is in everyone’s interest to regenerate and reuse core and moulding sand. However, after regeneration, some sands have changed properties.


The highest possible quality standard of our products is the declared aim – for every new development, for all HA systems applied throughout the world every day, for every batch.


HA Ilarduya Certified quality

Our clear commitment to comply with customer and product requirements earned us the quality management certification according to the UNE EN ISO 9001 standard, in the 1990s. In 2015, we integrated the security management systems and environment, obtaining the UNE EN ISO 14001 and OHSAS 18001 certifications. In 2020 we adapted the safety management system to the UNE EN ISO 45001 standard. HA Ilarduya is focused on continuous improvement, therefore, in 2019 we integrated a new management system, in this case of energy efficiency, obtaining the certification in the UNE EN ISO 50001 standard.

Even with everything we have achieved, we are determined not to rest on our laurels: For HA, the quality management process is never complete, it is continuously lived, developed and constantly monitored throughout the entire HA group. This approach allows us to identify and address potential for improvements at the earliest possible stage.

Energy efficiency and renewable energy

In order to optimise the use of energy across the group, both economically and ecologically, HA Ilarduya implemented an ISO 50001-compliant energy management system. This certification is not only recognition of all that we have achieved so far, it also provides an incentive and confirms our obligation to continuously strive to increase the energy efficiency of our company.

Energy-efficient management is one of our key corporate goals and is anchored in our leadership principles.

  • We integrate environmental and energy considerations into all operational decisions, including planning and procurement. 
  • Emission volumes and energy consumption are measured regularly and potential for improvement is identified and implemented.

HA Ilarduya does not just pay lip service to the efficient use of energy and the conservation of natural resources, these have long been among our core guiding principles. As a supplier to the high energy consumption foundry industry, we are always working on solutions to help improve sustainability throughout the sector.
