Recycling metals such as aluminium and steel couldn’t be easier. Yet only 30% of metal worldwide is currently recycled.
The brilliant thing about metal is that most types can be recycled forever without degradation of properties. And by using recycled metals, it saves further depletion of our planet’s natural resources.
Recycling tins and cans also saves energy, reduces CO2 emissions and diverts them from landfill or incineration. Plus, by recycling these materials separately, you’ll be sure of a higher recycling rate at a cheaper cost.

Steel and aluminium can be recycled forever, making them a great choice for closed-loop packaging.
Production of fresh aluminium, however, can be very damaging for the planet. Manufacturing new aluminium requires extraction of raw bauxite ore. In this process, the soil atop the deposit needs to be removed, meaning the vegetation at the mining site is destroyed. In 2012 it was also estimated that if we continue to consume aluminium as we do now, there is only 80 years' worth of natural aluminium left on this planet.
What's more, carbon emissions for extracting and processing fresh aluminium are alarming: more than 1 tonne of carbon dioxide is released into the atmosphere for every tonne of aluminium produced. Recycling aluminium, however, releases only 5% of the CO2 required to refine it fresh from bauxite. And the energy saved by recycling just one drinking can is enough to power a TV for up to three hours.
Steel tins and cans are just as good for recycling - in fact, steel is the most recycled material in the world and has been reprocessed for 150 years. Today, every food can is made of recycled steel - but it's also present in vehicles, home appliances and construction.
Recycling steel saves up to 74% of the energy required to produce it from virgin raw resources. One tonne of recycled steel reduces carbon emissions by 86% and water pollution by 76% when compared to fresh steel extraction.
In short, tin and can recycling saves resources, energy and carbon emissions - a no-brainer, really!
But how can you recycle steel? And how is aluminium recycled?
Well, everything starts with big magnetics that separate steel and aluminium products.
Aluminium is then shredded, decoated, melted and cast into ingots that are then transported to a rolling mill and rolled out to form aluminium sheets, from which new tins and cans can be made. Steel goes through a very similar process, but are usually converted into steel blocks instead of sheets.
As you can see, metal recycling is an easy step to help the environment - order your tins and cans recycling sacks today and get started!
