Liberty & sustainability

Composite air handling units, a durable quality product. Sustainability is a core theme for us on which we do not cut corners. On the contrary: we strive for the highest possible quality. For us, sustainability and quality go hand. Wherever it is technically, ecologically and economically responsible and feasible, we use recycled and renewable raw materials – and we would like to see the use of these materials grow in the coming years. Would you like to know more about how we strive for circularity?

Long lifespan with low maintenance costs

Our air handling units last longer. We see that, and our customers see it too. In addition, re-coating the inside of the casings every few years is unnecessary. Rosenberg NL also provides a 12-year warranty on the composite casing.

Surface treatment not required

Most metals will rust immediately upon exposure to the environment. This is a natural process that can be prevented by unnatural coating or environmentally harmful galvanising or coating. Composite is completely corrosion resistant and therefore does not require any surface treatment. This is important for the environment.

54% lower Carbon Footprint

A study by EuCIA shows that the Carbon Footprint of composites is 54% lower than that of aluminium and steel. This is because fewer fossil-based raw materials are needed for its production, and the production process requires significantly less energy. In addition, the considerably lower weight has an effect on the entire chain of production, transport, necessary construction, etc.

Use of recycled waste composite

The entire inner wall is covered with PET foil. This hygienic film is made from up to 80%  granulate from recycled (PCR) PET consumer and industrial waste. In accordance with legislation (EC) 1935/2004 and (EU) No 10/2011. The high-quality reuse of waste composite as a raw material for a technological end product fits the cradle to cradle philosophy.

After completing their longer lifespan, composites can be used as a raw material for the manufacture of concrete. The favourable properties such as sturdiness and low weight are also advantageous here.

Collaboration with the OPEN Foundation

The full name of OPEN is: Foundation for the Organisation for Producer Responsibility for E-waste Netherlands (OPEN). And we are responsible for the collection and recycling of e-waste on behalf of all manufacturers and importers of electrical appliances in the Netherlands from 1 March 2021. Our goal is to achieve the legal collection target of 65% and make e-waste circular. We can only realise this ambition together. 

To achieve the set objectives, mass is required: both in terms of commitment and financing. The OPEN Foundation works closely with chain partners. The OPEN Foundation is operational from 1 March 2021 and implements legal producer responsibility
