Is resin biodegradable?

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

Is resin biodegradable?

Resin is biodegradable if it is made from organic materials. Biodegradable resins include eco-resin, silicone resin, & epoxy resin. And non-biodegradable resins include polyester resin, polyurethane resin, & thermoset resins.

How is Resin Produced?

The majority of resin is a synthetic kind of plastic.

Refining crude oil into a form that may be utilized for a particular purpose produces plastics.

Large quantities of crude oil are converted into smaller hydrocarbon molecules called monomers during the production of resin.

Ethylene and propylene are examples of monomers, however, the specific kind of monomer generated depends on the type of plastic being manufactured.

Once the monomers have been generated, they undergo a distinct chemical process in which they are mixed to form polymers and resin. The resin is then modified with dyes and other chemicals, depending on its intended application, to impart distinct qualities.

The resin may subsequently be transformed into a kind of plastic or packaged and sold in its liquid state.

Does Resin Biodegrade?

There are several varieties of resins. These resins are not made from identical components. Others are created from synthetic fibers.

Biodegradable resin is exclusively created from organic resources. Biodegradable resins include eco-resin, silicone resin, & epoxy resin. And non-biodegradable resins include polyester/fiberglass resin, urethane resin, & thermoset resins.

The most prevalent kind of resin, epoxy, is biodegradable. Following an experiment, it was determined that two bacteria are responsible for the biodegradation of epoxy resin. The two bacteria that break down epoxy resin are Rhodococcus rhodochrous & Ochrobactrum anthropic.

Is Resin Better for the Environment Than Plastic?

The primary distinction between plastic & resin is that resins are made from organic substances. They are created directly from plants, while synthetic ingredients are used to create plastics. Resins are solid or semi-solid amorphous materials, however, plastic is a kind of synthetic resin.

The majority of eco-friendly resins, such as eco-resin, silicone resin, & epoxy resin, are natural and so do not pose harm to the environment. In contrast, plastic degrades slowly and contributes to environmental contamination.

When resins are dried & cured, they become ecologically benign, but plastic is not. After resins have been sanded and cured, they pose no hazard to the environment. 

Produced from synthetic fibers, plastics have few organic components. Therefore, plastic is more environmentally hazardous than resin.

Resin is recyclable since it is biodegradable and made from organic elements. It may be divided into smaller parts. Plastic is difficult to recycle since the recycling process sometimes entails burning. 

Plastic, when burnt, emits toxic gases such as furans, dioxins, mercury, & poisons. All of these are harmful to people, animals, and the environment.

When plastic is discarded in landfills and ends up in the ocean, it presents a significant danger to marine life. Plastic is not an organic substance, hence its consumption by aquatic creatures is hazardous. 

However, biodegradable resins may be broken down by microorganisms and bacteria, providing no hazard to aquatic life.

How Quickly Does Resin Decompose?

To keep our environment a safe place to live, we must be very cautious with the goods we use and discard. Our ignorance, incompetence, and recklessness have rendered our environment practically uninhabitable. Our actions have contributed significantly to the reduction of animal populations.

To safeguard the environment, we must adopt the usage of compostable and biodegradable materials. Because these items are organic, they do not affect the environment. Instead, they feed it.

Resin is biodegradable. However, only eco-resin & silicone resin are composed entirely of organic substances. Therefore, they are the only biodegradable resins. At the reaction temperature, the rate of resin degradation accelerates, and the reaction time rises.

Some sites suggest that biodegradable resins disintegrate in five to seven days. Nevertheless, specific circumstances must be met for the resin to break down within the specified time frame.

Is Resin eco-friendly?

Most resins are not environmentally friendly since they are derived from crude oil and subsequent refining. Both the collecting of crude oil and the manufacturing of resin are very detrimental to the environment and its human and animal inhabitants.

There are several hazardous compounds utilized in the refining process that are discharged into the environment by their manufacturer.

Even if the garbage is properly disposed of, it may still damage the air, water, and land. Many individuals perceive silicone resin to be more environmentally friendly than epoxy, fiberglass, & polyurethane resin.

Since the silica used to create it is derived from sand rather than crude oil, they say that it is safer for the environment and for individuals than other forms of resin.

True, but the silicon collected from sand must still undergo processing and chemical reactions before it can be used. This indicates that silicone resin still has the ability to damage the environment but to a lesser extent.

Is Resin a sustainable material?

Because crude oil is a nonrenewable resource, any product made from it cannot be considered sustainable. The crude oil supply will soon run out due to over drilling and the increasing usage of plastics.

Therefore, epoxy, polyester/fiberglass, & polyurethane resins cannot be considered sustainable. Silicone resin is more environmentally friendly since it is derived from sand rather than crude oil.

However, even silicone is not totally sustainable owing to its co-production with chemicals derived from crude oil.

Is Resin Toxic?

The liquid form of resin is more hazardous than its solid form, notably epoxy & polyester/fiberglass resin. These specific forms of resin are often obtained in liquid form and are most frequently utilized for home purposes.

Without suitable protection such as a respirator, hazardous vapors may be breathed while working with epoxy and polyester/fiberglass resin. This may lead to asthma and other respiratory complications.

When working with any form of resin, it is also advisable to operate in a well-ventilated location and wear gloves.

Some of the compounds included in most resins are believed to be carcinogenic to both animals and humans. They are also capable of polluting water and soil.

Once the resin has solidified, however, its toxicity to humans reduces.

Is Resin recyclable?

Technically, epoxy, polyurethane, & silicone resins may be recycled, however, it is difficult to recycle them. Because they can only be recycled in certain ways, recycling plastics in these forms is expensive and energy-intensive.

Occasionally, recycling them requires the employment of chemicals to decompose them. Therefore, anyone attempting to be more eco-friendly by recycling these products must consider how eco-friendly recycling them truly is.

However, recycling resin is often reserved for major enterprises and businesses. You and I are unable to recycle resin since it must be transported to a facility to which we do not have access.

In other words, you cannot just bring resin to the local recycling facility.

Sustainable Substitutes For Resin

There are natural and environmentally friendly resins available. However, they will be somewhat more expensive than synthetic resin. However, this is a little price to pay for being environmentally friendly.

However, we should also note that, although being more eco-friendly, these items are still deemed fairly harmful.

Here are sustainable substitutes for resins:

  • EcoPoxy
  • CCR Biological Resin
  • Seal-Once Eco-Friendly Wood Protectant

I will now elaborate on these.


EcoPoxy resin is an excellent alternative to the epoxy resin that is derived from plants. The USDA has certified it as a BioPreferred Product. There are also a variety of colors and finishes available.
