Asbestos is a naturally occurring mineral that was once widely used in construction materials 

Asbestos is a mineral that was once widely used in construction and industry due to its heat resistance and durability. However, it was later discovered that asbestos exposure can cause serious health problems, including lung cancer and mesothelioma. Asbestos should be identified and removed from homes and workplaces to prevent exposure. In this comprehensive guide, we will discuss what asbestos looks like, where it is commonly found, how to test and remove it, and UK regulations and laws regarding asbestos.


Introduction to Asbestos


Asbestos is a fibrous mineral that occurs naturally in the environment. It was once commonly used in construction, insulation, and other industries due to its heat resistance and durability. However, it was later discovered that asbestos exposure can cause serious health problems, including lung cancer and mesothelioma. Asbestos is made up of six different minerals, including chrysotile, amosite, crocidolite, tremolite, actinolite, and anthophyllite.


What Does Asbestos Look Like?


Asbestos fibres are microscopic, so it is impossible to identify asbestos simply by looking at it. However, asbestos minerals have distinct visual characteristics that can help identify them. It is important to note that not all materials containing asbestos are dangerous, and the risk of exposure depends on the condition of the material and the amount of asbestos present.

Chrysotile (White Asbestos)


Chrysotile, also known as white asbestos, is the most common type of asbestos and accounts for 95% of the asbestos used in the UK. It is a soft, white mineral that can be spun into fibres. It is commonly found in products such as asbestos cement, floor tiles, and insulation.

Amosite (Brown Asbestos)


Amosite, also known as brown asbestos, is a harder and more brittle mineral than chrysotile. It is brown in colour and is commonly found in insulation and cement sheets.

Crocidolite (Blue Asbestos)


Crocidolite, also known as blue asbestos, is commonly considered the most dangerous type of asbestos. It is a blue-grey mineral that can easily break down into tiny fibres that can be inhaled. It was commonly used in insulation and cement products.

Tremolite


Tremolite is a white or grey mineral that is found in talc and vermiculite products. It is also found in some insulation materials.


Actinolite


Actinolite is a green or black mineral that is found in some types of insulation materials.


Anthophyllite


Anthophyllite is a grey or green mineral that is found in some types of insulation materials.


Where is Asbestos Commonly Found?


Asbestos was widely used in construction and industry until November 1999. It can be found in many different materials, including:


Asbestos Floor Tiles


Asbestos was commonly used in floor tiles as well as in the bitumen adhesive used to fix the tiles in place until the 1980s. These tiles may still be present in older homes and buildings.

Asbestos Cement


Asbestos cement was commonly used in roofing and siding materials. It can also be found in pipes, insulation, rainwater goods and many other products. Asbestos cement is one of the most common materials to still be present within buildings in the UK today.

Asbestos Insulating Board


Asbestos insulating board was commonly used in walls, ceilings, and fire doors until the 1980s. It was the buikders best friend and was used pretty much everywhere within construction making it both one of the easiest and also most difficult products to locate within buidings due to the nature in which it was used.

Asbestos Insulation


Asbestos insulation was commonly used in pipes, boilers, and other equipment. It can also be found in ducts, walls, loft voids and ceilings. Boiler rooms in older buildings are regularly found to be contaminated with asbestos insulation debris following sub standard asbestos removal works in the past.

Asbestos Roofing


Asbestos was commonly used in roofing materials. Asbestos roof tiles and corrugated roofing sheets are still present in many older buildings. It can be found in domestic, commercial, industrial and agricultural building roofs. Whilst the corrugated roof sheets are one of the easiest materials to identify visually, some asbestos cement roofing products were designed to look like natural slate meaning it can be very hard to identify without sampling. 

Asbestos Testing and Removal


If you suspect that your home or workplace contains asbestos, you should have it tested by a professional. Asbestos testing involves taking a sample of the material and analysing it under a microscope to determine if it contains asbestos. If asbestos is present and poses an imminent, it should be removed by a licensed asbestos removal contractor.


Asbestos removal involves sealing off the area and using specialised tools and safety equipment to remove the asbestos safely. The asbestos is then disposed of in a special landfill site.


UK Regulations and Laws Regarding Asbestos


In the UK, there are strict regulations regarding asbestos. The Control of Asbestos Regulations 2012 requires anyone who may come into contact with asbestos to have appropriate training and equipment. Employers are also required to identify and manage any asbestos present in the workplace.


How to Protect Yourself from Asbestos Exposure


To protect yourself from asbestos exposure, you should avoid disturbing any materials that may contain asbestos. If you need to work in an environment where asbestos is present, you should speak with a professional asbestos consultant first to ensure you can undertake your work safely, without disturbing the deadly material. If you can't, you will need the help of a licensed asbestos contractor.


Conclusion and Final Thoughts


Asbestos is a dangerous material that can cause serious health problems. It is important to be able to identify asbestos and have it removed by a licensed professional. If you suspect that your home or workplace contains asbestos, you should have it tested and removed as soon as possible. By following proper safety procedures, you can protect yourself and others from asbestos exposure.

Asbestos and the Circular Economy: Why It's Time to Stop Burying the Problem Twenty-five years after asbestos was banned in the UK, we’re still digging a hole—literally and metaphorically. Every day, across the country, asbestos waste is double-bagged, labelled, loaded into skips, and driven to landfill, where it will sit indefinitely, taking up valuable space, creating ongoing liability, and adding to our already bloated environmental burden. And yet, 2025 presents a different path. A smarter one. One that replaces disposal with repurposing, and turns a dangerous waste product into a useful, circular resource. The technology exists. So the question we should be asking isn’t “Can we recycle asbestos?” It’s “Why the hell aren’t we doing it already?” Landfill is Failing Us—But We’re Still Relying On It Let’s start with the basics. There are still over 1.5 million buildings in the UK that contain asbestos, most of them now approaching the end of their useful life. As these structures age or undergo refurbishment, the volume of asbestos waste is only going to increase. Right now, we handle that waste the same way we did decades ago: • Identify it • Remove it (usually under fully controlled conditions) • Seal it in heavy-duty plastic • Drive it to landfill • Bury it • Forget about it Except we don’t forget, do we? Because landfill space is running out. Disposal costs are going up. And the environmental cost? We’re only just starting to count it. There’s a Better Way—and It Already Works Here’s what most duty holders don’t realise: We no longer have to bury asbestos. Thanks to recent advances in thermal treatment technology, we now have a method that can safely denature asbestos, breaking down its fibrous structure and rendering it harmless. Companies like Thermal Recycling in the UK are already proving this is not science fiction. They’re using high temperatures to transform asbestos cement products—like corrugated roofing sheets—into an inert ceramic material that’s completely safe. But here's the best bit: That material isn’t just neutral. It’s useful. It can be crushed and graded into aggregate, which can be used in road construction, paving, and concrete mixes. Instead of creating a waste burden for the next generation, we’re creating a valuable, low-carbon building material. Why Aggregate Matters in the Carbon Equation The production of virgin aggregates—through mining and quarrying—is energy-intensive and environmentally damaging. It contributes significantly to CO₂ emissions and destroys natural landscapes. So by replacing some of that demand with recycled aggregate from denatured asbestos, we: • Cut carbon emissions • Reduce dependence on extraction • Shrink the environmental footprint of infrastructure projects • Extend the life of quarries and reduce waste tonnage That’s not just a win for waste management. That’s a win for the entire construction supply chain. And yet most people in the industry don’t even know it’s possible. Why Are We Still Burying What Could Be Reused? As someone who’s worked in asbestos compliance for over 20 years—and now helps business leaders manage risk more intelligently—I’ve seen the same patterns play out time and time again: • “We’ll just do what we’ve always done.” • “This project’s tight on budget—landfill’s cheaper, right?” • “We’re just following the usual route—it’s less risky.” Let’s be honest. That mindset is outdated, short-sighted, and lazy. Cost may always be a factor, but the belief that landfill is “cheaper” needs to be challenged. Once you factor in: • Long-term environmental costs • Reputational risk • Rising disposal fees • And the public pressure for sustainable practices Thermal recycling is already starting to make sense. Especially when the output is something usable, not something buried. Licensed Contractors: You Don’t Get a Free Pass Either This isn’t just about clients or duty holders. Licensed Asbestos Removal Contractors (LARC’s) have a moral obligation here too. And I say that not from a place of opinion—but from first-hand experience, day in and day out for over two decades. Too often, LARCs put profits over progress. They default to landfill because it’s faster, easier to price up, and keeps their margins clean. They know the alternatives exist—but they don’t explore them, let alone offer them to their clients. When you hold a licence from the HSE, you’re not just a business—you’re a guardian of public health. That comes with responsibility. Choosing the most sustainable, forward-thinking disposal route should be part of that. Especially when the technology is available, proven, and legal. It’s time for the industry to stop hiding behind what’s convenient and start leading from the front. A Moral Obligation for Everyone Involved Whether you’re a: • Local authority managing public buildings • Developer under pressure to go green • Commercial landlord looking to reduce liability • Or a licensed contractor with influence over disposal routes —you have a responsibility to look beyond the cheapest or fastest option. If there’s a proven, safe, and more sustainable way to manage asbestos, you have a duty to understand it before choosing to ignore it. Because let’s be honest: “We didn’t know” isn’t going to wash when the public starts asking why we’re still filling landfill sites with a problem we already have the technology to eliminate. So What Can You Do Differently? No one’s asking you to overhaul your entire waste strategy overnight. But you can—and should—start asking better questions: • “Is landfill our only option here?” • “Could this waste stream be recycled instead of buried?” • “What suppliers, contractors, or experts do we know who can help us explore this?” You don’t have to be a global pioneer. But if you’re in a position of responsibility, you should at least be aware that the old way isn’t the only way anymore. Final Thought: The Future Is Circular—Whether You Join In or Not Asbestos will be with us for decades to come. That’s a fact. But how we handle it—and whether we choose to keep repeating the past or do something smarter—is up to us. Thermal recycling and other denaturing technologies offer a rare opportunity to do something that actually moves the industry forward. Not just ticking the compliance box. Not just burying the problem. But solving it—and turning it into something useful in the process. If you’re involved in asbestos management in even the slightest way, ask yourself this: Are you part of the problem, or part of the solution?
