Aluminium is a particularly important raw material in modern industry. It is used for a wide range of products, from drinks cans to aircraft components. Due to its versatile use, aluminium is also a highly sought-after raw material. However, the production of new aluminium is very energy-intensive and results in high CO2 emissions. The recycling of aluminium offers a sustainable alternative here.
The recycling of aluminium plays a decisive role in protecting the environment. In contrast to new production, up to 95% of energy can be saved when recycling aluminium. This not only leads to a reduction in CO2 emissions, but also to a reduction in the extraction of raw materials. Aluminium can be recycled almost indefinitely without losing quality. This reduces the need for new aluminium and reduces the environmental impact of aluminium production.
The aluminium recycling process is comparatively simple and efficient. Old aluminium products are collected, melted down and processed into new products. The energy required for recycling is significantly lower than for the production of new aluminium. The closed cycle in aluminium recycling means that old products can also be reintegrated into the market, which saves resources and protects the environment.
All in all, the recycling of aluminium is therefore of great importance for the environment. It helps to save energy, conserve resources and reduce CO2 emissions. By recycling and reusing aluminium products, we can make an important contribution to environmental protection and promote the sustainable use of resources. It is therefore crucial that we all do our bit by disposing of and recycling aluminium products correctly.
Increasing efficiency by recycling metals such as copper and zinc
Increasing efficiency by recycling metals such as copper and zinc is of great importance, as the demand for these raw materials is constantly increasing.

A: The choice of the right non-ferrous metal can significantly influence the service life and efficiency of a product. Materials with high corrosion resistance and specific physical properties can reduce maintenance requirements and improve the functionality and reliability of the product throughout its lifetime. For example, the use of aluminium instead of steel in certain applications can reduce maintenance requirements, as aluminium has a higher corrosion resistance and is therefore less susceptible to rust. Aluminium is also lighter than steel, resulting in a reduction in weight, which can reduce energy consumption and costs for transport and handling. Another example is the use of copper instead of other materials in electrical applications, as copper has high conductivity and heat resistance. It is therefore important to consider the specific requirements and conditions of the application when choosing the non-ferrous metal to ensure the best possible performance and service life of the product.
Q: Why is the recyclability of non-ferrous metals an important factor in terms of environmental protection and sustainability?
A: The recyclability of non-ferrous metals plays an important role in environmental protection and sustainability, as recycling can significantly reduce energy consumption and CO2 emissions compared to new production. It also helps to conserve natural resources as fewer raw materials need to be extracted. By recycling non-ferrous metals, toxic heavy metals that are produced during the extraction and processing of primary metals can also be avoided. This helps to reduce the environmental impact of mining and protects people's health, while the recycling of non-ferrous metals also makes economic sense as the materials can be reused, saving costs for new production. Recycling can also create new jobs and strengthen the economy, so it is important that we all help to recycle non-ferrous metals and thus contribute to environmental protection and sustainability. By raising awareness of the importance of recycling and utilising efficient recycling processes, we can make an important contribution to protecting our environment.
