In this episode, I share why Earth Month holds such a special place in my heart, how a bold experiment in 2018 sparked meaningful conversations around waste, and why sustainability doesn’t have to be overwhelming. We explore how small, realistic steps can create real impact, and I also share an exciting Earth Month announcement to help you get started on your journey.

Mama Earth Talk Online Course

• Sustainability doesn’t have to be overwhelming, start small and build from there
• Progress over perfection is the key to long-term change
• Your daily habits are the best place to begin your journey
• Awareness (like noticing what’s in your bin) creates powerful change
• Small swaps, done consistently, lead to big impact over time
• You don’t need to do everything, just start with one step.
• The planet needs more people taking imperfect action, not a few doing it perfectly.

In this episode, I shares the real story behind building a sustainable hard-goods brand in the pet industry, unpacking the engineering, manufacturing, certification, and financial trade-offs that most people never see. From design constraints and material decisions to B Corp, 1% for the Planet, and sustainability reporting, this is an honest founder-level look at what it actually takes to balance environmental ambition with business reality, and why sustainability is a discipline, not a label.

• Sustainable product development is not theoretical, it’s constrained by tooling costs, manufacturing realities, minimum order quantities, and cash flow.

• A structured sustainability framework (Environment, People, Economy, Culture) is your decision-making filter when trade-offs get hard.

• Perfection can become paralysis, progress with sequencing is often more impactful than waiting for “100% sustainable.”

• Sustainability in hard goods lives in engineering decisions, not marketing language.

• Designing for longevity reduces waste, but can reduce repeat purchases. That’s a business model tension founders must face.

• The “most sustainable-looking” material isn’t always the most appropriate one. Context matters.

• Certifications are validation layers, not starting point, they should align with operational readiness and financial stability.

• Material compliance (FDA, REACH, BPA-free) is foundational and often more important than flashy badges.

• Sustainability reporting turns intention into measurement, and measurement drives accountability.

• Profit isn’t the enemy of sustainability, it’s oxygen. Without financial viability, environmental ambition can collapses.

• Transparency builds trust when it shows process, not perfection.

• Celebrating brands that are doing the structural work shifts incentives across the industry.

• Sustainability isn’t a label, it’s an ongoing discipline.

In this episode of Mama Earth Talk, we talk to Sahar Karoubi, founder of Bambuyu, a sustainable tissue company challenging the way everyday household products are made and consumed.

Together, we unpack something most of us use daily, toilet paper, and explore the hidden systems behind it, from deforestation and material sourcing to the real impact of “eco” alternatives. Sahar shares how her personal sustainability journey as a mother led her to build Bambuyu, why bamboo stood out as a powerful alternative to traditional tree-based tissues, and what it actually takes to create a sustainable product in a very conventional industry.
