Polyamide Nylon Sutures: A Sustainable Choice in Surgical Practices

Surgical sutures are indispensable medical devices used to close incisions and lacerations. Traditional suture materials like catgut, silk, and linen have given way to synthetic absorbable and non-absorbable alternatives in modern surgical practice. One of the most widely used synthetic suture materials is polyamide nylon suture, commonly known as nylon. With excellent performance characteristics and a favourable sustainability profile, polyamide nylon should be considered an eco-friendly suturing option.


Benefits of Polyamide Nylon Sutures

Polyamide nylon possesses several properties that make it an ideal suture material for many procedures. It has high tensile strength that rivals stainless steel. Unlike natural fiber sutures, nylon retains its strength and smooth passage through tissue even after repeated tying. It also has low tissue reactivity, eliciting minimal inflammatory response. These characteristics lend nylon sutures excellent knot security and wound support for up to 6 weeks in tissues.

Polyamide nylon sutures provide strength and durability comparable to non-absorbable options like polypropylene. Yet nylon is available in grades that become partially or fully absorbed over extended periods. This gives it versatility across wound types. Nylon’s strength, elasticity, and low friction make it suitable for cardiovascular, orthopedic, ophthalmic, and other surgical disciplines.


Environmental Sustainability Factors

Beyond its clinical utility, polyamide nylon offers sustainability advantages over other suture materials in certain environmental impact categories:

Renewable Raw Materials: While historically made from petrochemical precursors, nylon polymers can also be produced from plant-based sources like vegetable oils or fermented sugars. These renewable feedstocks provide building blocks for fully bio-based nylon suture production.

Recyclability: Most nylon sutures are monofilament extruded from virgin polymer. However, recycling initiatives demonstrate nylon can be reprocessed from post-industrial and post-consumer waste into suture-grade material.

Carbon Footprint: Life cycle assessments show that bio-based nylon production emits less greenhouse gases compared to petroleum-based nylon and other polymers. This reduces the carbon footprint of polyamide sutures.

By utilizing more renewable, recycled, and lower-carbon nylon feedstocks, manufacturers can enhance the sustainability of these essential medical products. More data is needed to compare nylon sutures and other suture materials fully across all sustainability indicators. However, current knowledge suggests nylon is a relatively eco-friendly suturing choice.


Challenges to Overcome

Despite promising sustainability potentials, there are challenges to scaling more sustainable production of polyamide nylon sutures:


Cost: Bio-based and recycled nylon polymers remain more expensive than standard petrochemical nylon. However, costs are projected to decrease as manufacturing technology matures.


Processing Limitations: Recycled polymer must meet strict specifications for medical-grade use. Impurities can compromise performance and biocompatibility. Additives may be needed to achieve necessary material properties during recycling.


Sourcing Complexity: Expanding plant-based and recycled nylon feedstock supply requires major coordination across chemical producers, suture manufacturers, waste management firms, and other stakeholders.

By investing in research and collaborative efforts to expand sustainable material sourcing, the nylon suture industry can navigate these hurdles.

The Road Ahead

Polyamide nylon sutures provide the high performance and biocompatibility needed in diverse surgical applications. Manufacturers should continue exploring bio-based and recycled polymers to improve the environmental footprint of this essential medical product line.

With sound data and industry cooperation, nylon sutures, positioned as a leader in sustainable surgery, can become a reality. Healthcare systems pursuing environmentally preferable purchasing programs should recognize the unique advantages polyamide suture offers. By choosing nylon sutures, facilities can support progress toward more renewable, recyclable, and eco-friendly healthcare.


Polyamide nylon has been a trusted monofilament polyamide suture material for decades thanks to its strength, handling, absorption profile, and biocompatibility. As sustainability rises in importance across healthcare, nylon emerges as a suture material potentially ahead of the curve. By harnessing more bio-based, recycled, and lower-carbon nylon feedstocks, manufacturers can offer a product line with excellent performance and improved environmental credentials compared to other synthetic sutures. There are still challenges to expanding sustainable polyamide suture production, but the material is poised to become an eco-friendly option for surgical wound closure. Healthcare facilities should recognize nylon’s unique sustainability advantages when purchasing sutures.
