As a material science expert with a focus on sustainable alternatives to traditional materials, I have been involved in the study and development of various synthetic materials, including those used in the fashion industry. My work has been centered around understanding the environmental and health impacts of these materials, and finding ways to improve their sustainability.
Polyurethane (PU) leather is a synthetic material that has gained popularity as an alternative to traditional leather due to its versatility and affordability. It is made through a chemical process that involves the reaction of a polyol and an isocyanate. The resulting polymer is then processed to create a material that mimics the look and feel of natural leather.
One of the primary concerns regarding PU leather is its toxicity. It's important to note that the toxicity of a material can be assessed from several perspectives, including its production process, the substances it emits during use, and its disposal.
Production Process: The production of PU leather is generally considered to be less toxic than that of PVC (polyvinyl chloride), another synthetic material used to create faux leather. The reason for this is that the manufacturing process of PU involves fewer harmful substances and produces less pollution. However, it is not entirely without environmental impact. The chemicals used in the production of PU can be hazardous, and proper management of these substances is crucial to minimize environmental harm.
Breathability and Comfort: Unlike PVC, which is known for being non-breathable and can lead to discomfort such as sweaty feet, PU is designed to be more breathable. This feature not only makes PU leather more comfortable to wear but also suggests a reduced potential for causing skin irritations or other health issues related to trapped moisture.
Emissions: When it comes to emissions, regular PU leather may off-gas volatile organic compounds (VOCs) during the initial stages of its life cycle. These VOCs can include substances that are harmful to human health and the environment. However, the extent of emissions can vary greatly depending on the quality of the material and the specific production methods used.
Disposal: At the end of its life, PU leather, like many synthetic materials, poses challenges for disposal. It is not biodegradable and can contribute to waste if not properly recycled or disposed of. Efforts are being made to improve the recyclability of PU and other synthetic materials to mitigate their environmental impact.
Regulations and Standards: There are regulations and standards in place to ensure that materials like PU leather meet certain safety requirements. These standards help to minimize the risk of toxicity to consumers and the environment.
In conclusion, while PU leather is considered to be a more environmentally friendly and less toxic alternative compared to PVC, it is not without its own set of challenges. The key to reducing the toxicity of PU leather lies in improving production methods, ensuring proper ventilation to minimize emissions, and promoting recycling and responsible disposal. As the demand for sustainable and ethical products grows, the industry continues to innovate and develop new materials that are safer for both people and the planet.

Today's vegan leather is made using polyurethane (PU), and it is so much better than PVC. Unlike PVC, PU is completely breathable, so it totally avoids the issue of sweaty feet. What's more, it is far less toxic to produce than PVC. ... However, regular PU is not completely squeaky clean.Feb 8, 2016
