How does Gränges work on sustainability?
Gränges contributes to a more sustainable society through efficient use of resources, continual streamlining of production processes, environmentally-conscious product development and focused safety work.
Furthermore, Gränges has comprehensive routines and guidelines for its purchasing, to ensure traceability and responsible use of resources in the entire supply chain.
How is Gränges contributing to a better environment?
A maximum metal yield, greater use of recycled aluminium and energy-optimising processes are absolutely crucial to Gränges financial results, while representing the company’s main contribution to reducing the environmental and climate burden.
How energy-intensive is Gränges’ production?
The production of primary aluminium requires a large amount of energy. However, once the metal has been produced, it can be recycled without quality deterioration, at only 5 % of the energy that is required to produce primary aluminium.
After metal procurement and personnel, energy constitutes the largest cost.
Direct energy savings are achieved partly by improving production equipment and processes, partly through the recycling of thermal energy from the processes. Waste heat is reused for heating of premises, amongst other things.
Gränges carries out regular energy surveys to identify improvement measures. Gränges has successfully reduced its energy cost per tonne of aluminium in the past three years, thanks to efficiency improvements throughout its processes.
How sustainable are Gränges’ products?
Aluminium is often called the green metal, thanks to properties that enable recycling and re-melting.
Gränges’ products enable smaller, lighter and more designable heat exchangers, thereby increasing economic efficiency and reducing environmental impact. The products increase the efficiency of customers’ production processes, and the performance of the end product, the brazed heat exchanger.
How does Gränges work with the supply chain?
With a view to ensuring sustainable supplier operations, Gränges has produced a new Supplier Declaration for all suppliers.
