Redefining Food Service Sustainability in Corporate Dining - A Conversation with David Mesagno & Peter D'Angelo

Welcome back to Going Zero, the sustainability podcast for leaders making a difference.

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.
