With its myriad of applications, charcoal has been a trusted companion to adventurers, campers, and survivalists for generations.
However, in recent times, another form of this wonder substance has gained attention – activated charcoal.
As the debate over which type to include in survival kits and bug-out bags heats up, it’s essential to understand the fundamental distinctions between these two powerhouse materials.
What Is Charcoal
Charcoal is a black, porous substance created by burning organic materials, such as wood, in a low-oxygen environment.
This process, known as pyrolysis, removes water, volatile compounds, and impurities, leaving behind a highly carbon-rich product. Its porous structure grants charcoal impressive adsorption capabilities, making it effective in various applications. It’s something that many preppers forget about!
Traditional charcoal is commonly used for cooking, heating, and as a fuel source.
On the other hand, activated charcoal is a specially processed form with increased surface area, rendering it highly absorbent and widely used in medicine, water filtration, skincare products, and more.
Its versatility and long history make charcoal an essential material in many aspects of human life.
What Is Activated Charcoal?
Activated charcoal is a highly porous form of charcoal created through a controlled process of heating carbon-rich materials like wood or coconut shells at high temperatures.
This treatment creates a vast network of small pores on its surface, dramatically increasing its surface area and adsorption capacity.
Unlike regular charcoal, activated charcoal is specifically designed to trap and remove toxins, impurities, and chemicals from liquids and gases.
Due to its remarkable adsorption properties, activated charcoal finds widespread use in various industries, including medicine for treating poisoning and overdoses, water filtration to purify drinking water, skincare products, air purification, and more.
What Are The Differences Between Charcoal & Activated Charcoal
Charcoal and activated charcoal are both carbon-rich materials, but they differ significantly in terms of their properties, preparation, and applications.
Preparation: Regular charcoal is produced by heating organic materials, such as wood, in a low-oxygen environment, a process called pyrolysis. This leaves behind a black, carbon-rich substance with a porous structure. On the other hand, activated charcoal undergoes an additional step called activation. After pyrolysis, the charcoal is exposed to oxidizing gases or chemicals, which creates an extensive network of small pores on its surface. This activation process significantly increases its surface area and adsorption capabilities.
Surface Area: One of the key distinctions between the two is their surface area. Traditional charcoal has a porous structure, but the activation process gives activated charcoal an incredibly larger surface area, sometimes reaching thousands of square meters per gram. This increased surface area provides more binding sites, enhancing its ability to adsorb a wide range of substances.
Adsorption Capacity: Regular charcoal has some adsorption capabilities, but activated charcoal’s expanded surface area makes it far more effective at trapping and retaining impurities, toxins, and chemicals. It is widely used for filtering and purifying water, air, and even in medical settings for treating poisoning and drug overdoses.
Applications: Traditional charcoal is commonly used as a fuel source for cooking and heating, as well as in some industrial processes like metallurgy. On the other hand, activated charcoal finds diverse applications due to its superior adsorption properties. It is used in water filters to remove contaminants, in air purifiers to reduce odors and pollutants, in medicine for detoxification, and even in skincare products to absorb excess oil and impurities.
Safety: While regular charcoal is generally safe for cooking and heating purposes, activated charcoal should only be used for specific purposes and under proper guidance. In medical settings, it is administered in controlled doses, and ingesting it without medical supervision may interfere with certain medications and lead to potential side effects.
How To Use Activated Charcoal and Charcoal
Using Activated Charcoal:
- Water Filtration: Place activated charcoal granules or sticks in a water filter or purifier to remove impurities, chemicals, and odors from tap or natural water sources.
- Medical Use: In case of poisoning or drug overdose, seek medical assistance immediately. Medical professionals may administer activated charcoal orally to help prevent the absorption of toxins.
- Air Purification: Use activated charcoal filters or air purifiers to reduce indoor air pollutants, allergens, and unpleasant odors.
- Skincare: Create face masks or cleansers by mixing activated charcoal powder with water or other natural ingredients to draw out dirt and toxins from the skin.
- Teeth Whitening: Use activated charcoal toothpaste or powder in moderation to help remove surface stains and whiten teeth.
Using Charcoal:
- Cooking: Use traditional charcoal in grills or barbecue pits to cook food, providing a smoky flavor to meats and vegetables.
- Heating: Burn charcoal in stoves or fireplaces to generate heat during camping or in emergency situations.
- Art and Drawing: Use charcoal sticks or pencils for sketching and drawing due to their soft texture and easy blending.
- Deodorizer: Place pieces of charcoal in closets, drawers, or refrigerators to absorb moisture and eliminate odors.
- Gardening: Crush charcoal and mix it with soil to improve drainage and provide essential minerals to plants.
FAQ
Can I use charcoal instead of activated charcoal?
While both charcoal and activated charcoal have similar origins, they have distinct properties and applications. Activated charcoal’s enhanced adsorption capabilities make it suitable for specific purposes like water filtration and medical use. Regular charcoal lacks this efficacy, so it is not a direct substitute for activated charcoal in those applications.
How do you use charcoal for survival?
In survival situations, charcoal can be used in various ways:
- Fire Starting: Use charcoal as a fuel source to start and maintain fires for cooking, warmth, and signaling.
- Water Purification: Make a makeshift water filter with charcoal layers to remove impurities.
- First Aid: Crush charcoal into powder and use it to create poultices for wound dressing to prevent infection.
- Food Preservation: Use charcoal to absorb moisture and keep food fresh for a longer time.
- Tool Creation: Charcoal can be used to make simple tools like charcoal pencils for writing or drawing survival maps and notes.
Is burnt wood activated charcoal?
No, burnt wood is not activated charcoal. Burnt wood is regular charcoal, created through the pyrolysis process of heating wood in a low-oxygen environment. Activated charcoal, however, undergoes an additional activation process using oxidizing agents, which significantly increases its surface area and adsorption capabilities.
What is an alternative to activated charcoal?
An alternative to activated charcoal for certain applications is bentonite clay. Bentonite clay also has adsorption properties and is used in some water filtration systems, skincare products, and digestive health supplements. However, its adsorption capacity may not be as high as activated charcoal for certain purposes.
How do you know if charcoal is activated?
To determine if charcoal is activated, look for specific characteristics: activated charcoal is highly porous with a larger surface area, often appearing as fine black powder or granules. It is usually labeled as “activated charcoal” on the packaging and is commonly used in medical, water filtration, and air purification applications.
