Reducing Food Waste in Buffet Restaurants

Reducing Food Waste in Buffet Restaurants

How can the global foodservice industry effectively combat the massive challenge of food waste, especially in the context of popular buffet-style restaurants?

Food waste is a global issue with profound economic and environmental consequences. According to the United Nations, approximately one-third of the world’s food is wasted each year, costing an estimated $750 billion and occupying vast agricultural land. In this context, the hospitality industry stands as a major contributor to food waste, accounting for 17% of total food waste, a significant portion of which is avoidable.

While extensive research has examined food waste in various segments of the hospitality industry, buffet-style restaurants have received limited attention. Buffet restaurants present unique challenges due to their all-you-can-eat model, which often results in significant food waste. This article delves into this relatively unexplored territory and presents a corporate management approach to reduce food waste in buffet restaurants.

Food Waste in Buffet Restaurants: A Growing Concern

Buffet-style restaurants are recognized as among the most significant food-waste generators in the hospitality industry. Factors such as large portions, diverse menu options, unpredictable customer demand, and restaurant culture contribute to this issue. Buffets typically yield more food waste compared to à la carte restaurants due to uneaten food on plates and service counters.

The causes of food waste in buffet restaurants can be categorized into several key areas:

  • Forecasting Food Demand and Menu Design: Accurate forecasting of food demand is crucial to reducing food waste. Menu planning plays a pivotal role in mitigating food waste. Extensive menu choices, while essential for attracting customers, can lead to excess food production and, consequently, more waste.
  • Measuring and Monitoring Food Waste: To identify common plate waste items, separate waste bins are recommended in preparation and service areas. Continuous monitoring of food waste, including customer plate waste, can significantly reduce waste generation.
  • Communicating and Engaging Employees and Customers: Awareness among employees and customers about food waste is essential. Effective communication throughout the foodservice process, from menu planning to guest education, can play a critical role in reducing waste.

The Global Challenge of Food Waste

Throughout the world, the foodservice industry is undergoing rapid expansion, leading to a proliferation of restaurants catering to diverse tastes and preferences. This growth, however, exacerbates a pressing issue: food waste. In 2020, the global community grappled with the staggering problem of food waste, with an estimated 1.3 billion tons of food discarded each year, equivalent to roughly one-third of all food produced. This issue transcends national boundaries, impacting economies and the environment on a global scale.

Buffet-style restaurants, renowned for their popularity, face distinct challenges in tackling this problem, yet research on effective strategies to reduce waste in these establishments remains limited. This concern is not isolated to any specific region; it is a worldwide predicament that necessitates innovative solutions and heightened awareness across the foodservice industry.

Corporate Management Approach to Reduce Food Waste

This study investigated food waste management practices in Taiwanese buffet restaurants. The research identified and evaluated food waste at various operational stages and developed corporate management strategies to minimize waste. Key strategies include:

  • Establishing a Central Kitchen: A central kitchen can help control food quality, reduce spoilage, and minimize waste in the pre-restaurant stage.
  • Cooperation with Qualified Suppliers: Partnering with trusted suppliers can ensure a steady supply of fresh ingredients, reducing the risk of overstocking and waste.
  • Accurate Forecasting: Accurate forecasting of customer numbers and food demand enables better planning and reduces unexpected waste.
  • Aesthetic Restaurant Design: Open kitchens and personalized dish plates can enhance the dining experience while minimizing food waste.
  • Redesigning the Service Method: Smaller portion sizes and open kitchens can reduce waste by giving customers more control over their meals.
  • Measuring and Monitoring Food Waste: Regularly monitoring food waste at both preparation and service stages helps identify areas for improvement.
  • Proactive Communication: Engaging with both employees and customers through training, feedback mechanisms, and awareness campaigns can lead to a reduction in waste.


Food waste in buffet restaurants is a pressing concern, with substantial economic and environmental consequences. The study conducted in Taiwanese buffet restaurants highlights the importance of implementing a corporate management approach to tackle this issue effectively. Strategies encompass pre-restaurant practices, on-site preparations, and engagement with customers and employees.

As buffet restaurants continue to thrive in Taiwan and worldwide, adopting these food waste reduction strategies can not only benefit the environment and economy but also enhance the sustainability of the foodservice industry. Furthermore, collaboration between government bodies, restaurant operators, and customers is essential to creating a comprehensive and effective framework for reducing food waste in buffet restaurants.
