Trimmer line is a type of plastic string used in garden trimmers, weed whackers, and other tools for cutting grass and weeds. It is typically made from hardened, monofilament nylon, a synthetic polymer that is durable and resistant to breakage. While nylon trimmer lines are commonly used due to their strength and flexibility, they have also raised concerns about plastic pollution. As the nylon string wears away during mowing, tiny pieces of plastic are scattered into the environment, contributing to microplastic pollution. To address this issue, biodegradable alternatives like Biotrim have been developed, which aim to reduce the environmental impact of trimmer lines by naturally decomposing over time. However, the effectiveness of these biodegradable options has been debated, as they may still contain nylon or turn into microplastics that persist in the environment.

What You'll Learn
Trimmer line is often made from nylon
When used in trimmers, the nylon line is subjected to significant friction and force, causing it to wear away and break into tiny pieces. These small fragments of nylon are then scattered across yards, gardens, roadsides, and natural habitats. The problem is exacerbated by the high speeds at which trimmers operate, often reaching 28,000 feet per minute. This results in the dispersal of countless nylon particles into the environment.
The presence of these microplastics in the environment poses a significant ecological concern. Animals, both domestic and wild, may mistake these plastic particles for food, leading to potential harm or even death. Additionally, the tiny pieces of nylon can find their way into water bodies, contributing to the growing issue of plastic pollution in oceans and other water sources.
To address this environmental challenge, some companies have developed biodegradable trimmer lines. One notable example is Biotrim, which claims to offer a 100% biodegradable alternative to traditional nylon lines. After a decade of research and development, Biotrim's product is designed to decompose when it comes into contact with the soil. This innovation represents a step towards reducing the environmental impact of trimmer lines and promoting more sustainable landscaping practices.
While nylon is a common material for trimmer lines due to its durability, the environmental consequences of its disposal have sparked the creation of biodegradable alternatives. These eco-friendly options aim to strike a balance between effective trimming and reducing the persistent problem of plastic pollution caused by nylon trimmer lines.

Nylon is a synthetic polymer
Trimmer line is often made from Nylon, a synthetic thermoplastic polymer. Nylon is the name of a family of synthetic polymers that are commonly used to make a variety of different types of apparel and consumer goods. It is a plastic that is highly durable and versatile.
Nylon was the first commercially successful synthetic thermoplastic polymer, developed by researchers at DuPont. DuPont's experience with rayon, another synthetic fibre, was an important precursor to its development and marketing of nylon. DuPont's invention of nylon spanned an eleven-year period, from the initial research program in polymers in 1927 to its announcement in 1938, shortly before the opening of the 1939 New York World's Fair. The first nylon, nylon 66, was synthesised on February 28, 1935, by Wallace Hume Carothers at DuPont's research facility.
Nylon is entirely synthetic, which means that it has no basis in organic material. It is made from organic (carbon-based) chemicals found in natural materials such as coal or petroleum. The main ingredient of nylon fabric is petroleum oil. It is also possible to make nylon from renewable materials, such as castor oil.
Nylon is made by reacting together two fairly large molecules using moderate heat (roughly 285°C or 545°F) and pressure in a reaction vessel called an autoclave. One of the starting molecules is called hexane-1,6-dicarboxylic acid (also called adipic acid), and the other is known as 1,6-diaminohexane (also called hexamethylenediamine). When they combine, they fuse together to make an even larger molecule and give off water in a chemical reaction known as condensation polymerisation.
Nylon is not biodegradable, and as such, is a source of plastic pollution.

Nylon is not biodegradable
Trimmer line is often made from nylon, a synthetic polymer and a type of plastic. Nylon is not biodegradable, and the improper disposal of products containing nylon can lead to microplastic contamination. Even when nylon is properly disposed of, microscopic pieces of fibre will slough off as it is worn and washed, contributing to waterway and ocean pollution.
Nylon is a polymer composed of repetitive units of diamines and dicarboxylic acids that contain different numbers of carbon atoms. The resulting mixture can be cooled and the filaments stretched into an elastic thread. The manufacturing process for nylon has several direct environmental impacts, including the production of nitrous oxide, a greenhouse gas that is 300 times worse than carbon dioxide.
Nylon is also derived in part from coal and petroleum, supporting some of the world's dirtiest industries. When nylon is washed, it releases microplastics, which are tiny bits of plastic that are one of the biggest sources of ocean and shoreline pollution, killing marine life at a rapid rate. These microplastics are often mistaken as food by birds and animals, both domestic and wild, and end up in the digestive systems of wildlife, causing harm.
While there are some biodegradable alternatives to nylon trimmer lines, such as Bio-Line and BioTrim, these products are not entirely honest about their biodegradability. BioTrim, for example, contains nylon, which does not biodegrade. The manufacturer claims that the final process is soil bacteria eating the nylon, but bacteria do not further process microplastics. Instead, the microplastics exist inside the bacteria and anything that eats them, moving up the food chain.
Therefore, while there may be alternative trimmer line products on the market, it is important to remember that nylon is not biodegradable, and the improper disposal of products containing nylon can have severe environmental consequences.

Biotrim is a 100% biodegradable alternative
Trimmer line is typically made from nylon, a synthetic polymer and disposable plastic item. This has led to concerns about plastic pollution, as the nylon is worn away during mowing and scattered in the environment.
Biotrim's string trimmer line is designed to resist early breakage and holds up well to multiple uses. Its twisted outer layer also reduces noise. In addition, the packaging that the line comes in, including both the plastic and the packaging body, is also biodegradable.
While some have questioned the biodegradability of Biotrim, claiming that it still contains nylon, the product has been certified by a French certifying body as taking between 5 and 10 years to decompose once in contact with the soil.

Trimmer line can be used for 3D printing
Trimmer line, often made from nylon, can be used for 3D printing. Nylon is a synthetic polymer, a disposable plastic item, and string trimmers use a lot of it. It is worn away during mowing and scattered into the environment. This has led to concerns about plastic pollution.
Nylon trimmer line is available in hardware stores and can be a cheaper alternative to 3D printing filament. It is also available in smaller quantities, so you don't need to buy a full spool. The diameter of trimmer line is also consistent with the range of normal 3D printing filament.
However, there are some challenges to using trimmer line for 3D printing. Nylon is hygroscopic, meaning it absorbs moisture, which can affect the printing process and the final product. To mitigate this, the trimmer line can be dried before printing. Additionally, some materials not intended for 3D printing may release toxic fumes when heated, so it is important to print in a well-ventilated area.
Despite these challenges, some people have successfully used trimmer line for 3D printing, achieving good layer adhesion and flexibility in their prints. The average strength of the printed parts was also impressive, although there were some issues with material buildup at the nozzle and stringiness in the final product.
Overall, while trimmer line may not be the ideal material for 3D printing, it can be a feasible alternative in certain situations, especially for small parts or when nylon is specifically required for its flexibility and strength.
