Our Flagship Product

GRIND Z

GRIND Z is the world's first pencil lead made from recycled coffee grounds, representing ZIROBIO's breakthrough in sustainable innovation by combining eco-friendly materials with artistry. Free from graphite, its natural brown hue, derived from coffee, offers a smooth and clean drawing experience while contributing to a greener planet.

How It’s Made

  • Collecting Spent Coffee Grounds

    We begin by sourcing spent coffee grounds directly from local coffee factories.

  • Grinding and Drying the Coffee Grounds

    The collected coffee grounds are then finely ground and thoroughly dried.

  • Crafting the Pencil Leads

    Finally, the specially treated coffee grounds are meticulously crafted into GRIND Z pencil leads, using the natural color of coffee instead of traditional graphite and pigments.

Four Standout Advantages

  • ✅ Recycled Coffee Grounds

    Free from graphite—GRIND Z is made from recycled coffee grounds, making it more than just a pencil lead; it’s a revolution in sustainable artistry. Each lead is crafted by repurposing waste from coffee factories, transforming what was once discarded into something valuable and practical. 1 Coffee = 6 Leads.

  • ✅ Vintage Brown

    Embrace the unique, natural brown hue of GRIND Z. This vintage-inspired color, sourced directly from the coffee itself, offers a distinctive look with the rugged texture of coffee grounds, adding a unique touch to every sketch or word. If you’ve ever used brown charcoal, you’ll understand the magic of this shade.

  • ✅ Eco-Friendly & Skin-Friendly

    GRIND Z is as gentle on the planet as it is on your skin. Made with natural ingredients and free from harmful chemicals, it’s designed for those who care about their environmental impact and health. No smudging or dirty hands—GRIND Z provides a clean, hassle-free experience, making it safe for everyday use.

  • ✅ Like the taste of coffee?

    Then you’ll love the rich coffee aroma that accompanies every GRIND Z pencil lead. It inspires your creativity, reminding you of the product’s sustainable origins, and adds an extra layer of sensory pleasure to your creative process.
