Recycled Content
Sustainability Workshop
Increasing the recycled content in aluminium HPDC foundries is a game-changer for both sustainability and business growth. By using more recycled aluminium, especially post-consumer scrap, foundries can slash their carbon footprint and save energy. This not only helps the planet but also cuts production costs. With better recycling technologies and processes, foundries can handle more recycled content without losing quality, making them greener and more efficient.
These improvements attract eco-conscious customers who care about sustainability. As more businesses look for environmentally friendly partners, foundries with high recycled content stand out. They become the go-to choice for companies wanting to meet their own green goals. By highlighting their commitment to using recycled content, foundries can build strong relationships, grow their customer base, and boost their business success.

Where does the carbon footprint come from?
Primary aluminium is made from the ore Bauxite. After several steps, the Hall–Héroult process uses molten cryolite and aluminium oxide at 950 to 1000°C. With graphite electrodes, the aluminium oxides are reduced to pure aluminium. At the graphite electrode, carbon dioxide is formed. So, it takes about 17 kWh of energy per kilogram of aluminium without calculating losses. That is a lot of energy; depending on the source of the energy, it affects the carbon footprint.
Secondary alloys are made from scrap, so they do not need to go through the mining process, which saves a lot of energy. It is easy to understand that increasing the recycled content of alloys decreases the carbon footprint massively. But is all aluminium’s recycled content the same?
There are post-industrial and post-consumer scraps. Only the post-consumer scraps are rated with 0 kg CO2 per kg Al. For the post-industrial scrap, the carbon footprint of the production is from having to be accounted for.
The problem is that everyone is looking for high-quality scrap to increase their recycled content. So, one way is to pay more for post-consumer scrap than for primary alloys. The other way is to find innovative solutions to increase the recycled content where the specifications can be lowered.
Start your Sustainability Journey with the Goldcasting Podcast episode:
In this Gold Nugget, we discuss the trend toward sustainability. T What are the ways to reduce the carbon footprint, and at what cost? Who is paying for the change towards low-emission castings? Does any purchase organisation care for sustainable castings, or is it just about saving pennies? How do CBAM and Catena-X impact the industry?
How can sustainability improve your business?
The mission at Casting-Campus is to guide foundries on their journey toward sustainability. From assessing the feasibility of green initiatives to implementing eco-friendly technologies to weaving sustainability into the fabric of their operations.
The Imperative of Sustainability
Foundries embracing sustainability are not just adapting to industry trends; they are pioneers of positive change. The imperative to reduce environmental impact, optimize resource utilisation, and meet the growing demand for eco-conscious manufacturing is driving a paradigm shift in the foundry sector.
Sustainable Casting Processes
Sustainable casting processes designed to minimise waste, energy consumption, and environmental footprint are at the forefront of this shift. From implementing closed-loop systems to recycling initiatives, foundries can significantly reduce their environmental impact while maintaining operational efficiency.
Aligning with Industry Trends
Sustainability isn't just a moral imperative; it's a strategic advantage. Industries worldwide are increasingly seeking suppliers who share their commitment to environmental responsibility. Foundries that align with these trends position themselves as preferred partners, opening doors to new collaborations and market opportunities.
Cost-Efficiency Through Sustainability
Many sustainable practices lead to significant cost savings, contrary to the misconception that sustainability comes at a cost. Energy-efficient processes, waste reduction, and recycling initiatives contribute to a greener planet and enhance a foundry's bottom line.
Educating and Inspiring Change
Education is crucial beyond implementation. Through workshops, training programs, and collaborative initiatives, I strive to empower foundry teams with the knowledge and tools to embrace sustainable practices, fostering a culture of continuous improvement.
In the sustainability workshop, we review these points, assess them individually for your foundry, and determine the best strategy to increase recycled content, weave sustainability into your operation, and market that to your customers. Schedule a meeting today to learn more about how sustainability helps your foundry.

Secondary Alloy Dilemma
Using secondary alloys can reduce carbon emissions, but it’s complex. Secondary alloys come from post-industrial and post-consumer scraps. Only post-consumer scraps have a 0 kg CO2 footprint. Casting alloys need high purity, limiting usable scrap sources. Producing casting alloys often requires adding silicon, adding 0.5-0.6 kg CO2 per kg Al. High-purity scrap is scarce, so securing your supply is crucial.
