## The Food Waste Challenge Under the Table, Part 7 (Central News Agency, Reporter Jiang Mingyan, Taipei, 12th) The biggest waste in all-you-can-eat buffet restaurants is not in the back-of-house kitchen, but on the front-of-house tables. Data shows that over 60% of food waste from buffet restaurants comes from customers' leftovers. Facing sustainability pressures, cost challenges, and customer satisfaction, operators must find a balance. As consumer culture shifts towards quality, the era of 'eating to get your money's worth' is fading, bringing new opportunities for the food and beverage industry to reduce waste at the source.
With the 2027 ban on using food waste for pig feed approaching, as the food and beverage industry actively seeks new solutions for food waste disposal, a more fundamental issue has surfaced. The industry now recognizes that 'reducing waste at the source is more effective than post-processing.'
When it comes to all-you-can-eat buffets, most people intuitively believe that waste comes from over-preparation in the kitchen or excessive food on the serving counters.
However, after analyzing data, Han Lai Gourmet (漢來美食) found that its five Harbor Buffet restaurants generate approximately 361 metric tons of food waste annually. Of this, front-end preparation accounts for only 20-30%, soup stock residue accounts for about 10-20%, and the remaining over 60% comes from leftovers on customers' tables.
In contrast, for the Han Lai Gourmet group's Chinese cuisine brands, 50-60% of food waste comes from ingredient processing, 20-30% from soup stock residue, and less than 10% comes from what customers actually leave uneaten.
This data highlights the core of food waste in the industry and has led operators to realize that 'the real waste in all-you-can-eat buffets is not in the kitchen, but in customers taking too much and not finishing it.'
## From Large Plates to Small Plates: Changing Customer Eating Habits
Once the source of waste was identified, restaurants began adjusting their operational strategies. Han Lai Gourmet took the lead in its buffet restaurants by replacing large serving plates with smaller round plates, aiming to change customers' habit of 'filling the plate first' to 'take what you can eat.'
Another buffet operator stated that customer leftovers are the largest component of overall food waste. Therefore, in recent years, they have gradually increased made-to-order dishes, reduced portion sizes, and even designed dishes to be 'one-bite' sized.
'We don't want customers to feel restricted. The goal is to gently guide them to take appropriate portions without affecting their dining experience,' the operator said.
## Food Conservation is More Than Just Cleaning Your Plate: The Industry Seeks to Bridge Sustainability and Consumer Expectations
In recent years, the Ministry of Environment has been promoting food conservation environmental education, with the core concept being 'source reduction,' rather than creating massive amounts of waste and then finding ways to deal with it.
According to UN statistics, about one-third of the world's food is wasted during production, transportation, and consumption, with more than half of this waste concentrated in restaurants and at the consumer level. This discarded food not only generates a large amount of kitchen waste but also increases greenhouse gas emissions.
The Ministry of Environment emphasizes that 'food conservation is not just about not leaving leftovers; it's about fully utilizing the ingredients as much as possible and maximizing the value of the food.'
In recent years, many food and beverage brands have tried to integrate sustainability concepts into their operations. Han Lai Gourmet, for example, collaborates with local small farmers to turn food waste into organic fertilizer, which is used to grow tomatoes and asparagus that return to the restaurant's tables. They have also made drinks from 'ugly' fruits and vegetables, creating a circular economy model.
However, a gap remains between ideals and market reality. Han Lai Gourmet admits that while turning leftover parts of expensive salmon into fried fish skin or grilled fish bones aligns with the spirit of using everything, it may clash with consumer expectations for a high-end buffet. 'Balancing sustainability, cost, and customer satisfaction is always a challenge.'
In the past, some food and beverage brands promoted using 'substandard' fruits and vegetables in their dishes. However, they later found that 'farmers' associations had to put in extra effort to sort out the substandard items, and kitchen chefs needed more skill to trim the ingredients,' which actually increased costs. As a result, they stopped using this as a primary selling point.
## The Qualitative Change of the Buffet 'Little Happiness' Supports the Foundation of a Circular Economy
Regarding Taiwan's prevalent all-you-can-eat culture, a government official privately stated, 'This is not just an environmental issue; it's also a health issue. The more advanced a country, the less it encourages excessive eating as a consumer appeal.'
However, the market is also changing. Ting Yuan-Wei (丁原偉), General Manager of Yun Pin International (雲品國際), believes that all-you-can-eat is a long-standing food culture in Taiwan, and the market is shifting from 'quantity' to 'quality.' As the unit price at many buffet restaurants exceeds NT$2,000, 'consumers' goals have shifted from 'getting their money's worth' to pursuing premium ingredients and a sense of surprise.'
Ting gave an example, stating that Yun Pin's restaurants have expanded the sense of premium value from the food itself to the brand experience and the value proposition of not wasting. For instance, they have elevated the buffet to a fine dining experience, where steak is cooked to order, or served tableside.
Chang Huang-Chen (張皇珍), Deputy Dean of the Commerce Development Research Institute, also believes that in the future, in addition to the food and beverage industry using AI to analyze leftover data and optimize preparation, it is even more important to continuously raise consumer environmental awareness.
