Tackling Food Waste at Scale with Ben Lephilibert

Episode 34 of The Exponential Show features host Mayank Singh in conversation with Ben Lephilibert, CEO of LightBlue and Co-Founder of The PLEDGE on Food Waste.

With over a decade of experience working closely with kitchens, chefs, and hospitality operators, Ben has built one of the most structured approaches to tackling food waste in the industry. His journey highlights how a problem hiding in plain sight can become a global mission when approached with the right mix of systems, discipline, and persistence.

An Accidental Entrepreneur with a Clear Mission

Ben describes himself as an accidental entrepreneur. Originally from France and Denmark, he arrived in Thailand without a clear plan and eventually found himself working in hospitality through an opportunity with Accor.

His early work in sustainability exposed him to a wide range of environmental challenges across hotels. But one issue stood out immediately. Food waste.

What surprised him most was not just the scale of the problem, but the complete lack of data. Kitchens were throwing away large amounts of food every day, yet no one could quantify how much or why.

This gap led him to build his own methodology. Starting with a single hotel, he introduced a simple but powerful system. Every piece of wasted food was measured, categorized, and analyzed. Over time, this evolved into a structured approach that combined data, training, and operational changes.

That was the foundation of LightBlue.

From Methodology to Global Standards

As Ben and his team worked with more hotels, it became clear that food waste was not being treated as a serious business issue.

Most operators relied on assumptions rather than actual measurement. Many believed food waste was limited to buffets or visible leftovers, while the majority of waste actually occurred behind the scenes in preparation and storage.

To address this gap, Ben co-founded The PLEDGE on Food Waste, a certification system designed specifically for hotels, restaurants, and canteens.

The PLEDGE introduced a structured framework based on best practices, measurable criteria, and clear milestones. It gave organizations a way to not only reduce food waste but also demonstrate accountability and progress.

Today, it is recognized as one of the leading certifications in this space.

The Biggest Misconceptions About Food Waste

One of the key insights from Ben’s work is how misunderstood food waste really is.

First, very few organizations actually measure it. Without data, food waste remains invisible and therefore ignored.

Second, most people associate food waste with buffets or customer leftovers. In reality, buffet waste typically accounts for only a small portion of total waste. The majority comes from spoilage and preparation processes.

Third, the financial impact is often underestimated. When properly calculated, food waste can cost hotels hundreds of thousands of dollars annually.

Finally, there is a structural disconnect. In many cases, the people managing kitchens are not the ones directly bearing the financial cost. This reduces the urgency to act.

Scaling Impact Through Technology

In the early years, Ben’s work was highly manual. Data was collected using spreadsheets and basic tracking systems.

Over time, this evolved into a technology platform called FIT, which digitizes food waste tracking and analysis.

FIT allows kitchens to collect real-time data across multiple dimensions, including category, kitchen, shift, and type of food. This enables operators to identify inefficiencies with precision and take targeted action.

However, Ben is clear that technology is not a silver bullet. It is an enabler.

Real change still depends on leadership, culture, and consistent execution. Even simple measurement systems can significantly reduce waste when combined with the right mindset.

Lessons from the Ground

After working across hundreds of kitchens, Ben has seen both progress and resistance.

One recurring pattern is underestimation. Chefs often believe they waste far less than they actually do. When measured properly, the numbers can be several times higher.

Another challenge is inertia. Even when solutions are proven to deliver strong financial and operational benefits, some organizations hesitate to adopt them due to perceived effort or resistance to change.

Despite these challenges, Ben has also seen meaningful success. Large hotel groups have saved significant costs while reducing their environmental impact, proving that change is both possible and scalable.

The Bigger Opportunity

While much of Ben’s work focuses on hospitality, he emphasizes that food waste exists across the entire supply chain.

From farms to manufacturing to distribution, significant amounts of food are lost before they even reach consumers. In some cases, perfectly edible food is discarded simply because it does not meet aesthetic standards or market pricing conditions.

This creates a massive opportunity for innovation.

New models are emerging that connect surplus food from producers to buyers who can use it effectively. These solutions not only reduce waste but also create economic value.

What Keeps the Mission Alive

After more than 13 years in this space, Ben remains optimistic.

He points to a growing awareness around sustainability and a shift in how organizations are starting to approach food waste. More importantly, he draws motivation from working with people who genuinely care about making a difference.

At its core, his belief is simple. The alternative to solving this problem is not acceptable.

That conviction continues to drive his work forward.
