Trimmer line, also known as string trimmer line, is a type of plastic line used in lawn care and gardening. It is a synthetic polymer made from nylon, a disposable plastic item. During use, the trimmer line is worn away and can break into small pieces, becoming a source of plastic pollution in the environment. While most trimmer lines are not biodegradable, some eco-friendly alternatives, such as Biotrim, are made from biodegradable materials and are designed to decompose when in contact with soil. Trimmer lines come in various shapes, including round, square, diamond, and six-sided lines, with edged lines providing a stronger cut but a higher tendency to break. The durability of the line also depends on its diameter, with thicker lines being less prone to breakage but requiring more engine power.

What You'll Learn
Trimmer line is often made from nylon
Nylon trimmer line is worn away during mowing and spewed into the environment at high speeds, becoming microplastics. These microplastics can be harmful to the environment as they are difficult to address due to their small size, and they can be ingested by organisms, leading to poisoning.
To address the environmental concerns associated with nylon trimmer lines, some companies have developed biodegradable trimmer lines made from natural fibres such as cotton, hemp, or other eco-friendly options. These biodegradable options are designed to break down over time and return to the environment without causing harm.
One example of a biodegradable trimmer line is Biotrim, which is made by Oregon and is 100% biodegradable. It is designed to only begin decomposing when it comes into contact with the soil, ensuring that it lasts a few years when stored indoors. Another example is the Laser Biodegradable Trimmer Line, which is made from biodegradable polymers and provides reliable cutting power.
While biodegradable trimmer lines are a more environmentally friendly alternative, they may not be as durable or long-lasting as nylon trimmer lines. Additionally, they may be more difficult to find in stores compared to traditional nylon or plastic options.

Nylon is a synthetic polymer
Trimmer line is made of nylon, a synthetic polymer. Nylon was the first commercially successful synthetic thermoplastic polymer. It was developed by researchers at DuPont, with the first nylon, nylon 66, being synthesised on February 28, 1935, by Wallace Hume Carothers at DuPont's research facility. In response, Paul Schlack at IG Farben developed nylon 6, a different molecule based on caprolactam, on January 29, 1938.
Nylon is a polyamide polymer, characterised by the presence of amide groups in the main polymer chain. It is obtained through the polymerization process, specifically as a condensation polymer that is produced by eliminating small water molecules during its formation. The polymerization process involves the chemical bonding of five or more identical units called monomers, which are then connected repeatedly to form isomers. These isomers are then strung together repeatedly to form polymers.
Nylon is commonly used to make a variety of different types of apparel and consumer goods. It is not biodegradable, and its production has significant environmental costs, including the use of raw materials (oil), energy consumption, waste produced during fibre creation, and eventual waste disposal.
Despite the environmental concerns, nylon has influenced and contributed significantly to society. It has led to scientific discoveries related to plastic polymerisation and has had an economic impact. Nylon is also highly durable and versatile, making it suitable for various applications, including hair combs, machine screws, food packaging, and toothbrushes.

Trimmer line is a source of plastic pollution
The plastic line used in trimmers is often made from nylon, a synthetic polymer that is not biodegradable. As a result, the line is disposed of without any attempt at recycling, leading to plastic pollution. This single-use plastic is used abundantly by landscapers, homeowners, and highway crews, with an estimated 90 million trimmers worldwide.
The pollution caused by trimmer lines is not limited to the immediate environment. The microplastics produced can be carried by stormwater into rivers and oceans, where they are ingested by marine life, causing poisoning and attracting toxins.
While some biodegradable options for trimmer lines exist, such as Biotrim, they are not widely available, and most people are unaware of their existence. These biodegradable options are made from natural fibres like cotton or hemp and break down over time without causing harm to the environment.
The plastic pollution caused by trimmer lines is a serious and overlooked issue. With the widespread use of trimmers and the non-biodegradable nature of their lines, microplastics are being dispersed into the environment, causing harm to ecosystems and marine life. It is essential to raise awareness about this issue and promote the use of biodegradable alternatives to reduce plastic pollution.

Biodegradable trimmer line is available
Trimmer lines are typically made of nylon, a synthetic polymer that is a disposable plastic item. In the course of mowing, the nylon string is worn away and released into the environment, causing plastic pollution.
However, there are now some options for biodegradable trimmer lines that are better for the environment. Biodegradable trimmer line is available, and it can be a great alternative to traditional plastic trimmer lines. While it may not be as durable or long-lasting as traditional trimmer lines, biodegradable options are much better for the environment and can help reduce plastic pollution.
One example of a biodegradable trimmer line is GreenLine, a 100% biodegradable product made of innovative bioplastics that biodegrade into humus, water, and CO2 within a maximum of 24 months. Unlike oxo-degradable trimmer lines, which only facilitate disintegration without completely degrading, GreenLine does not lead to the accumulation of microplastics. GreenLine is available in the Netherlands and Belgium, with plans to expand throughout Europe.
Another option is the oxo-biodegradable trimmer line by ECHO, which is certified by CNEP, a French research organisation for photo ageing. This line can degrade into the soil through exposure to sunlight, heat, and microorganisms over time.
While these biodegradable options are available, they may not be as widely accessible or popular as traditional trimmer lines. Some people may be concerned about the practicality of biodegradable lines, as they may break too easily. However, with the increasing awareness of plastic pollution, these biodegradable options can be a more environmentally conscious choice for those looking to reduce their impact on the environment.

3D printing trimmer line is possible
Trimmer line is typically made of nylon, a synthetic polymer that is a disposable plastic item. String trimmers use a lot of nylon strings, which are worn away and spewed into the environment during mowing, causing plastic pollution.
Nylon is also a strong and impact-resistant thermoplastic used in weed-trimmer lines. Interestingly, some trimmer lines can be used as 3D printer filament with good results, and they are generally cheaper and easier to obtain than 3D-printing-specific nylon filaments. However, it is important to note that some trimmer lines may release toxic fumes when heated, so 3D printing with these materials should only be done in well-ventilated areas.
When using trimmer line for 3D printing, it is essential to consider the diameter of the line. The standard diameter for 3D printing filaments is 1.75mm or 3mm, while trimmer lines typically have a diameter of 0.065" (approximately 1.65mm) or 1.7mm. This discrepancy can be addressed by using an extrusion factor of around 112% for a 1.75mm-based printer. Additionally, it is recommended to use a heated bed with glue stick or dried glue for better adhesion.
Nylon is a hygroscopic material, meaning it absorbs moisture. This can cause issues during 3D printing, as the moisture boils off and ruins the prints. To mitigate this, the nylon should be dried out before use, although some recommend leaving a small amount of moisture in the trimmer line to create a rougher surface for better layer bonding. It is also important to note that printing with completely dry nylon may result in reduced impact resistance and flexibility until the material reabsorbs moisture from the air.
In conclusion, 3D printing trimmer line is possible, and it can be a cost-effective alternative to traditional 3D printing filaments. However, it is important to take the necessary precautions to ensure safe printing and to address the challenges associated with nylon's hygroscopic nature.
