Is pencil biodegradable?

This blog post will answer the question, “Is pencil biodegradable” and cover topics like the biodegradability of pencils and frequently asked questions related to the topic.

Is pencil biodegradable?

Yes, pencils are biodegradable. While the majority of pencils are composed of biodegradable materials. However, not every component of pencils composed mostly of biodegradable materials is biodegradable.

What Materials Are Used to Make Pencils?

The majority of the materials used to make wooden pencils come from nature. Usually, cedar is used to make the pencil’s casing since it is a hardwood that resists warping and splintering.

Non-toxic paint is applied to the wood of certain pencils to help preserve it and, in some circumstances, to adorn it. Graphite makes up the portion of the pencil that is really utilized for writing.

The mineral graphite, a dark grey substance formed from mined carbon, is often combined with chemicals and clay to increase its toughness.

A ferrule is a name for the piece of metal at the pencil’s tip that retains the eraser. Aluminum was chosen as the material because it is readily available, lightweight, and easily moldable.

The rubber used to make the eraser, which comes from tropical rubber plants, is the eraser’s main component. Pumice, a different mineral that occurs naturally, is sometimes added to the rubber mixture.

Rubber erasers and graphite are both found in mechanical pencils. However, the graphite is enclosed in plastic rather than wood.

Similar to wooden pencils in many ways, colored pencils are made mostly of colored clay as opposed to graphite. Additionally, most colored pencils lack erasers.

Are Pencils Sustainable?

Given that they are mostly comprised of renewable materials, wooden pencils are sustainable. The only component of them that isn’t renewable, whether it comes from natural or synthetic sources of graphite, is that.

However, even if the graphite is synthetic, producing it uses a lot less crude oil byproducts than producing other items.

In terms of the resources, they are built of, mechanical pencils are not sustainable, particularly given that producing them requires additional crude oil, a non-renewable resource.

However, mechanical pencils may be sustainable in that sense if you use them often and just change the graphite in them.

Do Pens Cause More Environmental Damage Than Pencils?

Pens often cause more pollution than pencils, whether they are wooden or mechanical.

More environmentally friendly materials are used to make wooden pencils. The majority of pens are composed mostly of plastic and contain ink that is a suspension of colors and pigments in oil.

While some pens do feature refillable ink, most pens, particularly the more affordable ones, are intended to be thrown away as the ink runs out.

Despite the fact that mechanical pencils are mostly constructed of plastic as well, changing the graphite in them is more frequent and less difficult than doing the same with a pen’s ink cartridges.

Do Pencils Contain Lead?

The graphite used in pencils is often referred to as “lead.” The idea that pencils were previously composed of lead, but are now made of graphite instead because lead is hazardous, is a widespread one.

Since lead and graphite have extremely similar appearances, when lead was first discovered in the 1500s, people simply called it lead because they couldn’t tell the difference.

It wasn’t until the latter half of the eighteenth century that it was realized that what had been mistaken for lead was actually carbon, a completely unrelated element.

They gave this substance the name graphite, which comes from the Greek verb “graphein,” which means “to write.”

Can you compost pencil shavings?

Pencil shavings are often biodegradable, despite their sluggish decomposition. As a result, they may be used for mulching and composting.

They may also serve as a bug deterrent since they are often composed of cedarwood. This makes pencil shavings a fantastic addition to your backyard garden, especially when combined with their capacity to help maintain soil moisture.

In addition to gardening, pencil shavings may be utilized as art supplies or as firewood.

Therefore, if you discover that you have a lot of pencil shavings in your house, just visit Pinterest to find some lovely DIY art projects you can use them for.

What should you do with used pencils?

Even if you are no longer in need of or able to use your pencils, there are still a number of things you may do with them. These consist of:

  • Produce art
  • Make jewelry
  • Use them as seedling starting sticks.
  • Apply them like garden stakes.
  • Employ them to create Christmas tree ornaments
  • Use them as spools
  • Make birdhouses
  • Create a few dolls
  • Create a pencil stand.

I will now elaborate on these.

Produce art

You may use used pencils to make a variety of DIY projects. One possibility is to use them to adorn your photo frames.

Make jewelry

You can make earrings and many other jewelry items by breaking up used colored pencils into tiny bits and gluing the pieces together.

Use them as seedling starting sticks.

You may use old pencils as starting sticks for plants in your garden. Your seedlings will have something to cling to as they develop in this manner. Additionally, you may easily take the sticks out later and plant new seedlings on them.

Apply them like garden stakes.

Another option to utilize used pencils in your garden is in this manner. Put them in the ground in front of a row of seedlings, labeled with the plant’s name. 

They can survive the weather for a long period since they are strong. Everything should be OK as long as you wash them beforehand before planting them.

Employ them to create Christmas tree ornaments

To create Christmas tree decorations and other decorative items, you may connect them to other items.

Use them as spools

Are there any excess pieces of yarn, wire, or thread laying around your home? They can be wrapped around your used pencils, I suppose. Additionally, because pencils spin quickly, freeing the thread for usage is simple.

Make birdhouses

Old pencils may be piled and glued together to make lovely birdhouses that make wonderful toys for your children and animals.

Create a few dolls

You already know how crucial it is to have wooden dowel rods on hand if you’ve ever created a doll, particularly for the limbs and legs. 

Pencils, on the other hand, might be an excellent replacement for these dowels if you don’t have any. They are equally strong and are simple to cut to the desired size.

Create a pencil stand.

You can make a lovely pencil holder by hot-gluing your colored pencils into a round container.

Make coasters

You may make coasters out of your used pencils if you need some to hold hot beverages or even give as presents. Simply cut a few of them to the same height, then glue them all together.

Are pencils better for the environment than pens?

Pens are often constructed of polystyrene whereas pencils are typically made of wood & graphite, making pencils generally considered to be more ecologically friendly. But things are not always cut and dry.

The annual felling of up to 80,000 trees for the production of pencils continues. And to make things worse, carbon dioxide is added to the environment as a result of graphite mining.

Additionally, pencils last a lot less time than pens do. In the end, it is difficult to determine which is more ecologically beneficial. Since they both often wind up in landfills, they seem to both affect the ecosystem in various ways.

Can You Recycle Pencils?

Both mechanical and wooden pencils cannot normally be recycled curbside since doing so would require separating the pencils into their constituent parts before recycling, which would take a lot of time.

However, mechanical pencils, markers, and other plastic writing instruments as well as their packaging are now recyclable thanks to a collaboration between BIC and Terracycle, one of the market leaders in stationery.

Can Pencils Be Reused?

Technically, any pencil may be used again. You can keep sharpening wooden pencils until you run out of wood & graphite. A wooden pencil must be replaced with a new one when you’ve sharpened it to that degree.

If a mechanical pencil is still functional, it may be used more often. Instead of discarding the whole pencil when the graphite runs out, you may just add more.

Even if men don’t do it, if they did, it would help lessen the amount of plastic that ends up in landfills and make mechanical pencils a little more environmentally friendly.

Are There Eco-Friendly Pencil Alternatives?

Wooden pencils are the most environmentally friendly alternative when deciding between them and mechanical pencils.

But using recycled plastic to manufacture mechanical pencils and recycled or salvaged wood to make wooden pencils may both make them more environmentally friendly.

That being said, there aren’t any particular companies that just produce eco-friendly pencils.

But certain pencils, particularly those manufactured from recyclable materials, are produced by companies like BIC and Ticonderoga that are more environmentally friendly than their regular pencils.

Can a pencil case be biodegraded?

The only way a pencil case may be biodegradable is if it is made of components derived from natural resources, like a cork. Because cork is often soft, strong, and flexible, it is frequently utilized as an eco-friendly material to build pencil cases.

As a result, cork pencil boxes are renewable and degradable. Pencil covers made of plastic or other synthetic materials, however, cannot decompose. Even if they were to disintegrate naturally, it would take centuries.

Frequently Asked Questions(FAQs), “Is pencil biodegradable?”

How do pencils impact the environment?

Although the production of pencils may not have a significant environmental effect, the removal of trees has an influence on the environment. 

Pollution is produced by the factories that produce pencils, all the vehicles and machinery used in this operation, and the mining of all the resources for the ferrule and eraser.

Can pencils be recycled?

Since most pencils are constructed of recyclable materials, they may be recycled. Graphite, metal ferrules, natural or synthetic rubber, and woods like cedar and its species are often used to make wooden pencils in addition to graphite.

Can you compost pencils?

Pencil shavings are often biodegradable, despite their sluggish decomposition. As a result, they may be used for mulching and composting. They may also serve as a bug deterrent since they are often composed of cedarwood.

How long does it take for pencils to decompose?

Graphite use will continue until a better substitute is discovered or pencils are rendered obsolete. If the graphite is compacted securely in the landfill, it will disintegrate in 100 to 200 years or more.

How are pencils used again?

If a pencil or colored pencil is manufactured from genuine, untreated wood, it may be recycled. To recycle the eraser & metal ferrule separately, first, remove them. It is not possible to recycle mechanical pencils.

Which pencils are the most environmentally friendly?

Environmentally speaking, the mechanical pencil is preferable since it has the ability to endure a very long time. Unlike wooden pencils, which need replacement once the lead runs out, mechanical pencils may be easily refilled.
