In this episode, we dive into sustainability where the stakes—and the challenges—are at their highest: music festivals and live events. Our guest is Vivian Belzaguy Hunter, a trailblazer in festival sustainability who has transformed waste diversion, environmental protection, and behavioral change across massive, temporary “pop-up cities.”

From the chaos behind the scenes to the drive toward zero waste, Vivian shares how small decisions lead to big change, why recycling and composting efforts so often fall short, and how proactive planning can turn festivals into immersive classrooms for sustainability. Hear what sets truly green festivals apart from the rest, how organizers, vendors, and even artists play a pivotal role, and the innovations transforming the industry here and abroad. Whether you run a business, lead a campus, or love live music, discover what our wildest events can teach us about going zero—where change is possible, and sometimes, preferred.

Welcome back to Going Zero, the sustainability podcast for leaders making a difference. In this episode, we sit down with two industry powerhouses leading the charge in corporate hospitality and sustainability: David Mesagno, Executive Director, Amenities Services Lead, and Peter D’Angelo, North American Head of Global Hospitality Services. Both guests bring decades of experience on both the client and vendor side of food services, sharing their journeys from the restaurant world to steering sustainability initiatives at two of the world’s largest financial institutions.

This conversation dives into how sustainability has evolved from removing styrofoam cups to becoming a baked-in expectation at the corporate level, with clients now demanding innovative solutions from their partners rather than simply checking boxes. David and Peter explore topics like food waste management, single use reduction, the challenges of local sourcing, measuring real impact, and the pivotal role food and amenities play in shaping company culture and recruitment. You’ll also hear insights on partnering with disruptive vendors, piloting new technologies, and the importance of telling your sustainability story to employees.

Stay tuned for an open, forward-thinking discussion packed with real-world strategies, lessons learned, and actionable advice for organizations looking to lead on sustainability and redefine the workplace experience.

Welcome to another episode of Going Zero, the podcast where we delve into the people, innovations, and big ideas shaping the journey to zero waste. Today, we’re getting into the nitty-gritty of trash—literally—with Joe Dinardi-Mack, co-founder and CEO of Sourgum. As a fourth-generation recycling professional whose family has spent more than a century in the industry, Joe is uniquely equipped to talk about both its storied past and its tech-driven future.

Welcome to another episode of Going Zero, the podcast where we dive into real-world solutions to today’s toughest sustainability challenges. Our hosts, Christy Cook, Eric Passwalk, and Seth are joined by Amielle Lake, CEO of Carbonet, a company pioneering innovative chemistry to help industries recover, reuse, and waste less water—while dramatically cutting down on fossil fuel-based chemicals.

In this episode, Amielle shares her unique journey from digital marketing to sustainability entrepreneurship, and sheds light on the looming threat of global water scarcity. You’ll hear how Carbonet’s breakthrough technology is helping thousands of manufacturers, municipalities, and oil and gas operations treat wastewater more sustainably and cost-effectively—no environmental premium required.

We’ll dig into why water remains an underappreciated resource, the barriers to widespread adoption of new water tech, and the challenges of shaking up a multi-billion dollar chemical “cartel.” Plus, Amielle highlights Carbonet’s real-world impact stories, talks about safety improvements for workers, and discusses her work advancing women's representation in clean tech and investing through the Women’s Equity Lab.

Whether you’re a sustainability manager, a CEO, or just curious about how chemistry can help secure the future of our most vital resource, this episode will inspire you to rethink what’s possible—and the role every stakeholder can play in driving change.

This week, we're sitting down with Stephen O'Brien, formerly of the NY Dept of Education, to discuss driving healthy choices and sustainable solutions to a massive audience - 1.1 million students.

If you’re looking to drive real change—especially in education—Stephen O’Brien’s approach offers a playbook for creating measurable impact in even the biggest organizations. Here’s what you can learn from his experience leading sustainable food service transformation:

3 steps for successful, sustainable change:

**Step 1: Start with pilots, not mandates.**

Stephen didn’t try to overhaul everything at once—he launched small experiments like “Trayless Tuesdays” and salad bar pilots. Success with these prototypes gave him proof of concept and protected him from big, costly failures.

**Step 2: Build coalitions—especially with your end users.**

Lasting change came because he listened to students, staff, nonprofits, and policymakers, using their feedback to design solutions that actually worked for them. When students asked for better serviceware, he collaborated *with* them, not *for* them.

**Step 3: Use scale as leverage, not just as a challenge.**

Stephen pooled buying power through the Urban School Food Alliance. By aggregating demand, he negotiated better contracts for compostable plates and locally sourced food, making sustainable options affordable even in a giant system.

You may not be running the nation's largest school cafeteria, but you can always start smaller, test, scale, and invite others into the journey. Sustainable change is never solo work—and your allies may be waiting where you least expect them (including your youngest “customers”).

On the latest episode of Going Zero, hosts Christy Cook, Seth, and Eric sat down with Dominique Hadad, the founder of Green Scope Consulting. Unlike many established industry veterans, Dominique represents a powerful new generation in sustainability—young, bold, and determined to drive meaningful change from the ground up.

Dominique’s story begins with her Caribbean roots, where first-hand exposure to climate change impacts in Trinidad and Tobago created a deep awareness and resolve. In college at The Ohio State University, Dominique studied industrial engineering and soon found herself immersed in systems thinking—not just from textbooks but through real-world experience.

Some fun facts from the episode:

1. Dominique Hadad started her business right out of college, supported by winning Ohio State’s President’s Prize and a pitch competition—even though she didn’t see herself as an entrepreneur at first.
2. Dominique helped a local Columbus restaurant achieve over 90% waste diversion, making it functionally a zero-waste restaurant (and she “had to” eat their food during the process!).
3. Dominique crocheted a robot while studying engineering, earning her “engineering star”—but she was always more interested in connecting people and systems than building things.

As the conversation turns to the broader future of sustainability, Dominique observes a growing movement towards transparency and authenticity—especially among young professionals. Where once degrees in sustainability were rare, now they are proliferating, creating a richly diverse talent pool. She notes, too, that diversity must include age and difference in thinking—because innovation often comes from those who see the world differently.
