Hello, hello!
In this episode of the Good Garbage Podcast, host Ved Krishna sits down with Sandeep Kulkarni, Founder of Kool Earth Solutions and a global expert in sustainable packaging.
With experience spanning PepsiCo’s Advanced Research team, packaging innovation, and circular economy systems, Sandeep brings a rare insider perspective into how materials, business realities, and sustainability intersect.
🎙️ What This Episode Explores
This conversation goes beyond buzzwords like eco-friendly and biodegradable — and dives into the real science, trade-offs, and economics behind packaging materials.
From paper bottles to plastic recycling, molded fiber, and biopolymers, Sandeep explains why there is no perfect material — only better decisions depending on context.
If you’ve ever wondered:
- Can paper really replace plastic?
- Is glass actually more sustainable?
- What happens to your plastic bottle after you throw it away?
This episode answers it — honestly.
