Metal is one of the most recycled materials in the world, with steel being recycled the most in Europe at a rate of 79.5%Metal packaging is recycled more than any other primary packaging material. This is because metals can be recycled an infinite number of times, whereas plastic can only be recycled a certain number of times before it has to be downcycled, sent to a landfill, or incinerated. Plastic recycling is very energy-efficient, using 90% less fuel than new plastic, but plastic usage has skyrocketed in the last 50 years and recycling hasn't been able to keep up. Consumers in the UK, for example, only recycle one-third of their plastic packaging.

What You'll Learn
- Metal packaging is recycled more than any other primary packaging material
- Steel is the most recycled packaging material in Europe
- Metals can be recycled infinitely, unlike plastics
- Consumers have a strong preference for environmentally friendly products and recycling
- Plastic littering and pollution have a greater impact on the environment and human health
Metal packaging is recycled more than any other primary packaging material
The high recyclability of steel contributes to a more circular economy. For example, reports indicate that 75% of all aluminium ever produced is still in use today. In contrast, consumers in the UK only recycle one-third of their plastic packaging, with two-thirds ending up in landfills. While plastic recycling is energy-efficient, using 90% less fuel than new plastic, the process can only keep up to a certain extent with the skyrocketing production and use of plastic over the last 50 years.
Metal packaging is also preferred due to its environmental impact compared to plastic. Plastic can pollute land, rivers, lakes, and oceans, and it contains additives and chemicals like BPA that may be harmful to humans and wildlife. Microplastics are released when plastic breaks down, further contributing to environmental issues. On the other hand, metal packaging can be continuously recycled, reducing its environmental footprint.
Additionally, consumers have a strong preference for environmentally friendly products and packaging. They are more likely to support companies that adopt sustainable practices, such as using recyclable metal packaging. This shift in consumer behaviour encourages businesses to move towards more sustainable packaging options, reducing the use of plastic and promoting the recyclability of metal packaging.

Steel is the most recycled packaging material in Europe
The commitment to recycling steel packaging in Europe is evident in the industry's transparency and alignment with the EU's vision for a circular economy. The adoption of stricter recyclability measures, such as the Packaging and Packaging Waste Regulation (PPWR), further reinforces this commitment. The PPWR introduces a performance grading system that will phase out materials with less than 80% recyclability by 2038. Steel packaging consistently achieves grades A or B, outperforming other materials like plastics and laminated cartons.
The superior recyclability of steel packaging in Europe is attributed to the collective efforts of the industry and stakeholders. Steel for Packaging Europe, for instance, has played a pivotal role in advocating for sustainable practices and maintaining a 100% closed material loop. Their secretary-general, Steve Claus, has expressed pride in the industry's achievements and the harmonized method for calculating packaging recycling rates, which creates a level playing field for all packaging materials.
The recyclability of steel packaging in Europe extends beyond mere numbers. It reflects the industry's dedication to transparency and sustainability. With stakeholders working towards a common goal of a circular economy, steel packaging's ever-increasing recycling rates are a testament to the successful collaboration between the industry and policymakers. As a result, steel has become the most recycled packaging material in Europe, setting a standard for other materials to follow.
Additionally, steel is a highly recyclable material that can be reused multiple times without losing its quality. This makes it an ideal material for packaging, as it can be recycled and reused for the same purpose repeatedly. The unique properties of steel, such as its durability and magnetic properties, also make it easier to separate and sort during the recycling process, contributing to its high recyclability rate.

Metals can be recycled infinitely, unlike plastics
Metals, unlike plastics, can be recycled infinitely without any loss in the quality of the material. Aluminium, for instance, can be recycled endlessly and can be back on the shelf in less than 60 days after being tossed in the recycling bin. This is because metals are elements, and once they are transferred from the natural resource stock and enter the economy, they can be recycled indefinitely, provided their purity is maintained and systems are in place for their recovery.
The recycling process for metals is also more energy-efficient than creating new products from raw materials. Recycled aluminium cans, for example, take 95% less energy to produce than cans made from new aluminium. This helps to minimise environmental degradation and saves substantial amounts of energy and water.
In contrast, plastics are polymers, synthetic substances composed of very large molecules that break down when recycled. While plastic recycling is more energy-efficient than creating new plastic, using 90% less fuel, it is still not as eco-friendly as metal recycling. This is because plastic can only be recycled a limited number of times before it ends up in a landfill.
Glass, like metal, can also be recycled an unlimited number of times, making it a more sustainable option than plastic. However, it is important to note that not all types of glass can be recycled together due to their different melting points.

Consumers have a strong preference for environmentally friendly products and recycling
Consumers are increasingly demanding environmentally friendly products and sustainable packaging. A survey by The Economist found that consumers believe that brands have as much responsibility as governments to create positive environmental change. This shift in consumer behaviour is encouraging companies to increase their commitments to responsible business practices.
A recent study by NielsenIQ found that 78% of US consumers say that a sustainable lifestyle is important to them. Similarly, a 2020 McKinsey US consumer sentiment survey found that more than 60% of respondents cared about buying environmentally and ethically sustainable products. This trend is particularly pronounced among Millennials, who increasingly seek out brands that embrace purpose and sustainability.
In addition to their purchasing behaviour, consumers are also paying attention to the global climate crisis and how their products are packaged. A survey by Business News Daily found that 77% of respondents considered plastic to be the least environmentally friendly packaging material, while 55% considered paper to be the most environmentally friendly. The same survey also found that 72% of respondents were actively buying more environmentally friendly products than they did five years ago, and 81% expected to buy even more over the next five years.
While consumer demand for sustainable products is high, there is a paradox in that few consumers who express positive attitudes towards eco-friendly products and services actually follow through with their purchases. This could be due to the higher cost of sustainable products or the inability of companies to generate sufficient consumer demand for these products. However, as consumers become more educated about the environmental impact of their purchasing decisions, it is likely that the demand for environmentally friendly products will continue to grow.

Plastic littering and pollution have a greater impact on the environment and human health
Plastic pollution is a pressing issue that poses significant risks to the environment and human health. Unlike other materials, plastic does not biodegrade, leading to its accumulation in the environment. With over 430 million tonnes of plastic produced annually, two-thirds of which are short-lived products, the scale of plastic waste is immense. This waste often ends up in landfills, comprising 46% of plastic waste, while 22% is mismanaged and becomes litter, ultimately choking marine wildlife, damaging soil, and poisoning groundwater.
The impact of plastic pollution extends beyond the environmental realm, seeping into the human food chain. Plastic pollution in the ocean, predominantly caused by human littering, disrupts ecosystems' ability to adapt to climate change. It alters habitats and natural processes, exacerbating the challenges posed by global warming. The production of plastic contributes to this issue, as it is derived from chemicals manufactured during the production of greenhouse gas-emitting fuels.
The pervasive presence of plastic in modern life, from packaging to clothing and beauty products, underscores the urgency of addressing plastic pollution. While bioplastics offer promising alternatives with enhanced durability and lower production costs, the solution lies in a holistic approach encompassing design, reuse, repair, and recycling. Education is pivotal in combating plastic pollution, particularly nature-based environmental education, to foster a sustainable mindset among future generations.
In contrast to plastic, glass is easily reusable and can be transformed into storage containers, drinking glasses, and other creative purposes. Metal recycling, although energy-intensive in the manufacturing process, is more prevalent due to the economic value of recycled metal products. Plastic recycling, while energy-efficient, has limited applications, and once recycled, plastic often ends up in landfills.
To mitigate the environmental and health risks associated with plastic pollution, a multifaceted approach is necessary. Governments play a pivotal role in enforcing rules and regulations, while companies and consumers must share the responsibility of reducing, reusing, and recycling plastic products. By embracing alternatives like bioplastics and shifting behaviors away from single-use plastics, we can collectively address the detrimental impact of plastic pollution on our planet and human health.

Frequently asked questions
Metals tend to have a much higher recycling rate than plastic and can be recycled an infinite number of times. Steel is the most recycled packaging material in Europe, with 79.5% of steel packaging being recycled. In contrast, plastic recycling often struggles to keep up with the skyrocketing production of plastic goods.
Recycling metals contributes to a more circular economy. Some reports indicate that 75% of all aluminium ever produced is still in productive use. Metals also tend to be less harmful to the environment at the end of their lifecycle than plastics.
Recycling metals often requires a significant amount of energy during production. For example, aluminium is one of the most energy-intensive industries. Additionally, some metals made with alloys may require toxic or hazardous chemicals, such as chlorine, to break them down.
Plastic tends to be a lighter material than most metals, which means it may have a lower delivery, transport, and freight footprint.
