Writing, drawing, and doodling are just some creative activities that are even better when introducing colors—our shirts, sheets, and practically everything that isn’t in black and white. Even computers display better data in vibrant colors.
If everything looks better in an array of colors, what’s to happen to the environment when we encourage our indulgences? What are the effects of ink on the ecosystem? Is ink biodegradable?
Is ink toxic to the environment? If you have any questions about the post-use life of ink, this article will answer them.
Is Ink Biodegradable?
No, traditional ink is not biodegradable. It is made from varnish, oil, and pigments, and some of these ingredients are not natural. Biodegradability will not occur when dealing with inorganic substances, which is the bulk of what ink comprises.
Ink helps leave the mark that you desire. The history of this substance dates back to the 23rd century BC; people started with reed straws with strategic slits, moved on to quills, and eventually graduated to the ability to use ink even on printers and devices that aren’t pens.
Before the desire to expand beyond pens and quills, the ink used to be made purely from trees. But now we also use printers to inscribe on paper, shirts, billboards, and pretty much everything! If you can put a label on it, why not?
Now that the proliferation of ink is spreading, we must question its biodegradability status.
Judging by the materials it is made from, ink is not biodegradable. Let’s break down its essential components: varnish, oil, and pigments.
Varnish is made from resin, a plant product. Resin can also be extracted from animals; it is a chemical compound used to create the glossy surface of your inscriptions. Varnish isn’t bad for the environment because it is a bioproduct, but when other additives like polymers or synthetic materials are included, it renders the product non-biodegradable.
Oil is another component used in manufacturing modern paint. It is often petroleum-based, especially when you are dealing with conventional paint. Plastic or synthetic polymers are made from crude oil.
They are manufactured in a manner that they don’t break down, ever! Instead, we are left with microplastics and nanoplastics even decades after decomposition.
This is what also happens with the oil-based components of the ink. They will pollute the environment during decomposition. It is also worth mentioning that decomposition will not occur fast; it may take decades and even longer.
The final ingredient that goes into manufacturing ink is pigments.
There are three types of pigments – inorganic, organic, and metallic.
Metallic pigments are used in industrial applications. Metals like aluminum and zinc are the pigments included in this type of paint. It does not biodegrade.
Inorganic pigments are synthetic pigments, and they are used to achieve a variety of colors. This is the type used in the ink industry, but it is not suitable for the environment.
The last type is organic pigment – made from bioproducts. This type is biodegradable because it is made from organic matter.
Depending on the composition, it may break down fast, and it may not. If it has a mixture of biodegradable and non-biodegradable materials, you can assume which would break down first. The non-biodegradable parts will not break down fast.
Is Ink Toxic to the Environment?
Ink may be toxic. Traditional ink is bad for the environment because it is made from materials that don’t break down naturally. For instance, it has volatile organic compounds and heavy metals that do not break down. Ink takes a long time to decompose, depending on the environment it is put in.
Ink is toxic, simple. Without volatile organic compounds, achieving the fine print and attractive color that comes out on paper may be challenging. The vibrant colors you see result from an array of acids and chemicals, such as the reactive red 23 dye and direct blue dye.
Other chemicals found in ink include ethylene glycol, ethylenediaminetetraacetic acid, and butyl urea.
These are potent compounds that will undoubtedly harm the ecosystem during decomposition. It is bad enough that non-biodegradable items take longer to degrade, but it is even worse when the materials in question are hazardous to the environment, like ink.
That’s not all the harm this item causes – it contains oil, which does not mix well with water. So, if oil makes its way into our water bodies, it will affect the balance of the marine habitat. It will also poison the ecosystem if it spills on land.
Crude oil is present in ink. Crude oil is the same substance used in manufacturing plastics that never biodegrades. The singular fact that it is a component of ink causes the ink to lose its biodegradability status,
Titanium dioxide is also a common metallic substance found in the pigment of ink. Titanium dioxide is present in many products, including ink and sunscreen, but it is bad for the environment because it is not biodegradable.
The effects a material has on the ecosystem are determined by its ingredients. If they are toxic, they will negatively affect the environment one way or the other.
Is Pen Ink Biodegradable?
Pen ink is not biodegradable. It shouldn’t be encouraged to biodegrade naturally because it contains toxic chemicals. There are also non-biodegradable pigments; don’t expose leftover ink to the environment because microbes will not decompose it.
Biodegradable materials are items that will break down fast. They will also have no adverse effect on the environment. In other words, this is how nature breaks down or recycles our waste.
Now, not all materials are biodegradable. In most cases, manmade items will not biodegrade because of their inorganic nature. They often need to be fortified with synthetic polymers to improve their strength and durability.
Ink is an example. Of course, there are ink types that are made from biodegradable substances. The very first pens ever used were made from natural materials in the 23rd BC. This was long before we understood that we could expand our manufacturing activities.
Fast forward to the present moment, and we have found a way to produce ink with different enticing features. Nevertheless, these inclusions harm the environment because they render ink inorganic and incapable of natural degradation.
Furthermore, composting ink that is not biodegradable is not a good idea because it will cause environmental pollution. As mentioned earlier, ink is made from materials like oleic acid, alkyl alkanol amide, and crude oil-based oil.
The pigments for the ink aren’t also good for the environment.
The ink does not mix well with water and may find its way to our water bodies if not disposed of properly. If it is polluting the landfill or even your yard, it leaches toxicity into the soil and surrounding biodiversity.
There are plenty of reasons to avoid biodegrading ink.
Is Printer Ink Biodegradable?
No, printer ink is not biodegradable. There are different types of printer ink – petroleum-based, soy-based, or vegetable oil-based. However, none of the available printer ink products on the market are entirely biodegradable. They must contain petroleum or other synthetic material for better functioning.
Conventional printer ink is not suitable for the environment because it contains materials that are not biodegradable. Crude oil used to be essential for manufacturing ink. It was even more indispensable for printer ink, as you will see when you go through old newspapers.
That ink contained heavy metals that don’t biodegrade. Therefore, leaving them to be broken down in the environment was always the wrong choice.
The heavy metals will disrupt the balance of where they are left. Since landfills have been designed for this purpose, they don’t contain a significant portion of living biodiversity. Therefore, it is more reasonable to leave the waste there.
Printer ink will not biodegrade unless it is a hundred percent natural. Water-based products may satisfy this need, but even they need to be appropriately disposed of. There are solutions for industrial users of ink because they consume it on a large scale.
Is Ink Compostable?
No, ink is not compostable. This is especially if we are talking about conventional ink. Although ink wasn’t always toxic, it grew to be so because of the constant improvement humans strive to achieve. Now, some products contain heavy metals, chemicals, and dyes. These extras are not suitable for the compost pile or the environment, for that matter.
We don’t recommend composting ink. There are many reasons for this, but let’s start with the fact that it is not biodegradable. Ink does not break down because it contains petroleum and other synthetic materials. They take forever to break down, but the toxic substances will leach into the environment before that happens.
Another reason you should avoid composting ink is that it is inorganic matter. The essence of composting is to gather resources from organic matter while also biodegrading them in the way that nature would.
This means only organic matter is allowed. Everything in a pile decomposes within a specific time so that you can relieve the environment of the waste while also nourishing the soil and plants.
Oil-based ink will pollute this wonderful creation and leave a mess that you will not like looking at. In addition to this, they release volatile organic compounds or VOCs that pollute the environment.
Can You Compost Paper with Ink?
You can compost paper with ink, but it also depends on what the ink is made of. If it is one of the modern biodegradable options, go for it! However, if the ink is not biodegradable, i.e., made from petroleum-based products, it is best to avoid composting it.
Before composting paper with ink, check that the print was not made some fifty-something years ago. At this time, we were still printing our words with non-biodegradable ink.
But now, there are water-based options that microbes will break down seamlessly. Those are the ones you should compost.
Is Water-Based Ink Eco-Friendly?
Yes, water-based ink is eco-friendly. It is eco-friendly because it is water-soluble, which means it breaks down in the water. However, water-soluble pens are not yet in great use because they dry fast.
Conventional ink is not biodegradable because it is petroleum-based. However, biodegradable options are arising; these are vegetable-based and lack chemical additives, ensuring that biodegradation takes place.
