Biodegradable inks are environmentally friendly printing inks made from natural materials that can break down over time. Unlike traditional inks, which often contain harmful chemicals, biodegradable inks use plant-based substances, such as soy or vegetable oils, making them safer for the environment. These inks are designed to decompose naturally when exposed to moisture and microorganisms, reducing waste in landfills. They are commonly used in packaging, labels, and printing materials, helping to promote sustainable practices in the printing industry while minimizing the ecological impact of printed products.
