Aluminum: Surprisingly Sustainable

Aluminum is actually one of the most recycled and recyclable materials available. According to the Aluminum Association, almost 75% of all the aluminum ever made is still being used today! Its many useful properties, including being lightweight and corrosion-resistant, make it great for all sorts of applications. The benefits of aluminum combined with the difficulty in creating it from scratch drove the development of our current robust aluminum recycling systems!

Before the discoveries of the Héroult/Hall electrolysis process and Bayer's refining method using bauxite ore, aluminum was considered a precious metal and was very valuable- even more than gold!

The current method of making virgin aluminum is to refine it out of bauxite ore extracted from open-pit mines in places like Australia, Guinea, and Brazil.

The efficiency of recycling scrap aluminum means it takes only 5% of the energy needed to produce virgin aluminum. This 95% energy savings is great for both manufacturer's budgets and the planet- the more cost-effective recycled aluminum is, the more demand there will be for increased recycling.

In contrast to aluminum's 75% recycled rate, a study published in Science Advances in 2017 indicates that only 9% of plastics ever made have been recycled. Aluminum can also be recycled indefinitely. The majority of plastics can only be recycled a handful of times, and many of them only once!

How is aluminum recycled?

1. It is shredded into chips and sent through an infrared sorter to catch and remove anything that doesn't belong, such as plastic and glass. A magnet also checks for scraps of steel.

2. The scrap aluminum chips are melted down (1,221°F!) and poured molds to form ingots. These ingots can be huge, weighing up to 29.8 tons each (or 1.5 million aluminum cans)!

3. Ingots aren't always the most convenient form to give to manufacturers for reuse, so commonly a series of rollers is used to progressively squeeze the ingots down into sheets about .01" thick.

The ingot sheets are then rolled up into coils and ready to be used again!

How recyclable is SelectSpace?

SelectSpace Partitions are almost entirely aluminum! All the panels, stand bodies, and planter stand bodies are aluminum (the stand and planter stand bases are stainless steel).

This means once you are done with your partitions, they can be easily recycled and the metals reused. The stainless steel is also just as recyclable- steel is the most recycled material on the planet!

How can I make sure my metal is recycled?

For larger metal scrap (like SelectSpace), it's a good idea to contact a scrap/recycling company and arrange a drop-off or pick-up. Municipal garbage services may also accept the scrap, but usually only by special arrangement. Using a dedicated company or service ensures your scrap doesn't end up in a landfill by mistake!

Aluminum is considered a 'green' material and its closed-loop recyclability makes it a great choice for sustainable products and design. It's great to know that once SelectSpace and other aluminum products have reached the end of their life-span they won't just be dumped in a landfill. They could come back as food packaging, automobile parts, medical equipment, construction materials or thousands of other products used every day across the world!
