Sustainable materials in jewelry: the use of PLA in our pieces

At Suagongo, we believe every design choice is also an ethical decision.
That’s why our jewelry not only stands out for its originality and lightness but also for being made with materials that respect the planet. In this article, we’ll explain why we use PLA, a bioplastic derived from natural resources, and how this material is shaping the future of sustainable jewelry.

What is PLA and why do we choose it?

PLA (polylactic acid) is a plant-based material made from starches such as corn, sugarcane, or other renewable crops. Unlike petroleum-based plastics, PLA is biodegradable under industrial composting conditions and has a much lower environmental impact.

In the world of jewelry, PLA offers an innovative alternative to traditional materials like precious metals or plastic resins. At Suagongo, we choose it for its versatility, lightness, and above all, because it aligns with our vision of responsible design committed to the environment.

Benefits of PLA in 3D jewelry

One of PLA’s main benefits is its sustainability. Made from renewable raw materials, its production emits fewer pollutants and doesn’t depend on extractive processes like those used for metals or synthetic plastics. Moreover, PLA contains no toxic substances, making it safe for both the environment and the wearer.

Functionally, this bioplastic is surprisingly lightweight, allowing us to design large, voluminous, or sculptural pieces without compromising comfort.

Thanks to 3D printing, we work with great precision on geometric shapes or organic structures that would be difficult — or impossible — to achieve using traditional techniques.

Another key aspect of PLA is its aesthetic versatility. It supports a wide range of colors, textures, and finishes. At Suagongo, we combine it with natural pigments and manually intervene each piece to give it a unique finish, always maintaining our commitment to ethical and conscious fashion.

PLA versus traditional materials

Compared to the ecological impact of other materials, PLA represents significant progress. For example, metals like gold or silver require intensive mining processes that directly affect ecosystems and communities. Resins and acrylics, while versatile, come from petroleum and are not biodegradable. Even some recyclable plastics have limited lifecycles and generate waste if not properly managed.

In contrast, PLA is compostable under industrial conditions and fits into a more circular production model—especially when used on demand as we do at Suagongo. By printing each piece only when ordered, we avoid overproduction, reduce waste, and eliminate the need for large warehouses or inventories.

It’s not perfect, but it’s a big step

Although PLA requires industrial processes for complete composting, it remains one of the most sustainable options currently available in contemporary jewelry. At Suagongo, we choose it consciously as part of a broader responsible design strategy that includes local production, plastic-free packaging, and ethical relationships with our suppliers.

Conscious design, sustainable beauty

Every time you choose a Suagongo piece, you’re supporting a different way of consuming—one that respects your skin, your style, and the planet. Because we believe beauty lies not only in form but also in substance: in how it’s made, with what materials, and with what values.

For us, PLA is more than a material—it’s a statement of intent.
