From Environmental Management to Mining Exploration: The Many and Varied Applications of Remote Sensing

Spectral analysis has long been used to determine the composition of materials across a range of different fields. Until recently, this was generally done in a highly targeted way, with readings usually taken from small samples. However, advances in technology have allowed both the speed and scale of this testing to increase significantly, without compromising accuracy.

This has led to even wider adoption of this technique, with remote sensing applications now spanning many different industries. 

Here we take a closer look at what this technology is, how it works, and the different ways it is being used.

What is Remote Sensing?

Also referred to as airborne hyperspectral imaging, remote sensing is an analysis technique that provides detailed compositional data for large areas. 

Using high-resolution imaging and an aerial platform, like a drone, it can quickly map vast landscapes. By combining this with advanced spectral analysis, it can also see past the visible, and accurately assess chemical and geological structures.

History of Remote Sensing

Broadly speaking, the history of remote sensing began in the 1840s, when topographic images were first taken using cameras attached to tethered balloons. This practice quickly expanded, and by World War I, cameras were being attached to the underside of planes to support reconnaissance activities.

This was taken to the next level when, in 1957, Russia launched the world’s first artificial satellite, Sputnik I. While early satellites were primarily used for weather monitoring, the opportunity for large-scale imaging of the Earth’s terrain was soon recognised. This led to the 1972 launch of what would become known as Landsat 1, the first satellite designed specifically for earth observation.

Since then, remote sensing technology has continued to advance and adapt. This was spurred on by the start of the “Drone Age” in the early 2000s, when use of Unmanned Aerial Vehicles (UAVs) became much more widespread. This, combined with the development of more compact and lightweight spectral analysis tools has seen significant growth in the applications of remote sensing.

Common Remote Sensing Applications

Due to its speed, scope, and accuracy, remote sensing is now used in a range of industries, for a variety of purposes. Due to the depth of data it can produce, it is consistently seen as a superior option to more traditional analysis techniques.

Agricultural Operations

Farming was one of the first commercial industries to see widespread adoption of remote sensing at the individual operator level. Traditionally, factors like soil health and crop moisture had to be assessed manually, which was time-consuming and destructive. 

But now, almost every step of the growing process can be enhanced using advanced analysis techniques, without the loss of a single grain.

Early adoption of this technology saw UAVs being used to map farmland and monitor for obvious signs of infestations and diseases. The addition of spectral sensors has further developed this practice, enabling careful monitoring of crop health, soil quality, and crop moisture and nutrient levels. This has led to the development of precision agriculture practices, designed to increase productivity, boost yields, and improve sustainability.

Practical applications of remote sensing in agriculture include collecting and analysing the detailed data required to optimise farm management, as well as more specific applications like helping to fight citrus blight.

Mining Exploration

In the mining industry, accurate and detailed compositional analysis can quite literally be as good as gold. While extraction activities can be extremely lucrative, they can also be very expensive to set up and operate. As such, you need to be sure that the investment will be worth it.

Traditionally, this has meant extensive sample collection and laboratory testing to confirm the presence of valuable minerals in a site. 

However, even the most robust manual testing programs could not provide a reliable assessment of the size and potential value of a mineral deposit. This is where remote sensing technologies have really changed the game.

In addition to identifying valuable minerals in much smaller concentrations, spectral analysis can also identify the shape and size of a deposit. This supports a more accurate calculation of its value and better decision-making about where to invest. 

It can also help inform the selection of the optimal extraction sites and methods, making mining operations much more efficient.

By attaching sensors to a UAV, the speed and scope of analysis activities can be significantly increased. You also enable the safe assessment of sites that are difficult or dangerous to access on the ground.

Environmental Monitoring

As our focus on sustainability and preservation increases, so does the need for reliable data on the true state of our environment. 

Historically, this data has been limited by the extremely expensive and time-consuming collection process. However, remote sensing overcomes many of the barriers facing manual analysis, making it much quicker and easier to gather invaluable environmental insights.

Regular monitoring of sensitive landscapes allows changes to be tracked and interventions planned to slow degradation. 

Analysis of at-risk ecosystems enables us to evaluate their health and detect contamination or the presence of invasive species. Plus, measurement of the density and composition of vegetation can provide important insight into the state of forests and other critical green spaces.

Practical applications of remote sensing in environment research include coastal exploration projects and monitoring of the Great Barrier Reef for signs of coral bleaching.

Defence Activities

Since the earliest days of the technology, the military applications of remote sensing have been heavily explored. 

While the applications within defence remain largely the same – primarily surveillance and reconnaissance – the analysis that is now possible is far more advanced. This includes the ability to detect small changes in terrain and other evidence of concealed objects and infrastructure.

Over the last few decades, sustainability has become an increasing focus for commercial and industrial operations across the world. As a result, there has been widespread adoption of resource conservation activities, like the recovery and recycling of metal. 

This is particularly true here in Australia, where scrap metal is now a multi-billion dollar industry.

While recycling scrap metal has both environmental and economic benefits, it also presents a range of unique challenges. Most significantly, careful analysis and sorting are required to identify and correctly manage contaminated scrap metal. 

Failing to do this can have serious operational, environmental, and social consequences.

In this article, we will take a closer look at the many and varied risks associated with contaminated scrap metal. From health issues to financial impacts, we will explore what these risks are and how they are best managed.

What is Contaminated Scrap Metal?

From a recovery and recycling perspective, contaminated scrap is metal that contains other elements that make it unsuitable for processing. 

Often, the contaminant is fairly innocuous, like paint or dirt, and the metal can be easily cleaned. However, some contaminants, like asbestos and radioactive material, are much more serious and significantly harder to remove.

The Dangers of Contaminated Scrap Metal

The exact risks posed by contaminated scrap metal will depend on the nature of the contamination. Where some contaminants will only impact the value of the metal, others will make the metal dangerous to handle and process. 

Common dangers associated with contaminated scrap metal include:

Risk to Health

There are a number of contaminants that can result in serious health complications if they are not handled correctly.

Most obviously, exposure to metal that is contaminated with asbestos increases the risk of mesothelioma, an aggressive form of cancer. This is a particular concern in construction and steelworking environments, where asbestos coatings were once widely used to improve heat resistance. 

While asbestos was made illegal in 2003, metals produced before this time – and particularly before the 1980s – may still contain traces of asbestos.

Chromium 6 is another common scrap metal contaminant, as it is widely used in paints and coatings to help prevent corrosion. 

Direct exposure to this material can cause irritation of the skin and damage to the eyes. When inhaled, Chromium 6 can also result in asthma-like symptoms and increase the risk of developing lung cancer.

It is also possible for scrap metal to be contaminated with radioactive materials, though this is less common in Australia. The main sources of these metals are the industrial processing, mining, oil and gas, and medical fields. 

The impact of exposure to these materials will depend on the nature and strength of the radionuclide present but could include an increased risk of cancer.

Risk to Environment

If scrap metal is not properly identified and disposed of, contaminants like lead and mercury can leach into the soil and groundwater.

This pollutes the site, impacting the health of the local ecosystem and potentially limiting future uses of the area. It can also harm local plant and animal life, particularly if contaminants spread to nearby bodies of water (rivers, dams, etc.).

If they are not identified and removed prior, contaminants can also be released during the recycling process. 

To make it easier and more efficient to melt, once scrap metal has been collected and sorted, it is shredded. As the material is broken up, any contaminants are released, creating dust that impacts air quality and, depending on the contaminant, polluting the local environment.

Risk to Safety

Depending on how it was used and what it has been treated with, contaminated scrap metal can be combustible or explosive. This is particularly true if it has been pressurised, mixed or coated with flammable materials, or has significant rust build-up. 

It is crucial that these materials are identified, monitored, and handled correctly, including being kept away from welding and grinding activities.

The Costs of Contaminated Scrap Metal

In addition to potentially being dangerous, contaminated scrap metal can also be costly – both financially and operationally. Again, the exact impact will depend on what the contaminant is, but common costs include:

Reduced Resale Value

In addition to being good for the environment, there are also significant financial benefits associated with scrap metal recycling. 

For most commercial and industrial operations, these usually come from the sale of scrap materials to processing facilities. They can also be quite lucrative and help offset the cost of ongoing equipment and plant maintenance, repair, and upgrade activities.

However, scrap metal resale rates depend on its type, volume, and quality, and most facilities will conduct testing prior to purchase.

If contamination is identified, depending on what the contaminant is, the scrap may still be able to be sold. However, the price offered will be adjusted to reflect the additional work that will be required to clean and process the material.

Increased Handling Costs

Prior to sale, scrap metal needs to be recovered and sorted based on the type of metal (steel, copper, etc.). As part of this process, testing is often done to determine the exact composition of the material and identify any contamination. 

As contaminated scrap metal needs to be managed differently, its presence slows the sorting process, making it both less efficient and more expensive.

Scrap Metal Sorting Made Easy

There are a range of tools that can aid in the identification and management of contaminated scrap metals.

For asbestos screening, you can’t go past the lightweight, but powerful ASBpro. Using NIR technology, it can identify 6 different types of regulated asbestos fibres, and testing is quick, affordable, and non-destructive.

For everything else, there’s the Niton XL2 Plus. Able to detect elements from Magnesium to Uranium, as well as tramp and trace elements, it makes scrap metal identification fast, accurate, and reliable.
