Food Waste in Restaurants: An Urgent Call for Sustainable Action

As countries globally strive for economic growth and improved food security, an insidious challenge undermines their efforts: food waste. The alarming numbers concerning wasted food make it clear that food waste prevention is no longer just an environmental concern but a pivotal factor influencing food security, economic development, and our shared pursuit of the United Nations’ Sustainable Development Goals (SDGs).

The Startling Reality of Food Waste

Recent data from the United Nations Sustainable Development Goal report paints a grim picture:

• Globally, from 2000 to 2019, domestic material consumption, which includes food produced, surged by over 65%, amounting to a staggering 95.1 billion metric tons in 2019.
• In 2020 alone, 13.3% of the world’s food was lost between harvesting and reaching retail markets, including grocery stores.
• Even more, disheartening is that about 17% of total food available to consumers, which equates to 931 million metric tons, is wasted at the household, food service, and retail levels.
• When discarded into landfills, this uneaten food generates between 8 to 10% of global greenhouse gas emissions.

The Scale of the Problem

According to the United Nations Food and Agriculture Organization (FAO), approximately one-third of the food produced globally for human consumption – nearly 1.3 billion tonnes – gets wasted every year. The restaurant sector plays a significant role in this figure:

• United States: Restaurants contribute to around 11.4 million tonnes of food waste annually.
• United Kingdom: The out-of-home sector, which includes restaurants, is responsible for 1.1 million tonnes of food waste, equivalent to £3.2 billion.

Australia: Commercial and industrial sectors, including restaurants, generate 2.2 million tonnes of food waste each year.

The Economic and Environmental Impacts

The Natural Resources Defense Council emphasizes that wasted food translates to wasted natural resources, including the water, energy, and land used in food production.

Households contribute significantly to the problem of wasted food. Household food waste represents lost economic value and underscores the need for better education on storing food correctly to prolong its shelf life.

Food loss and waste in the production and supply chain, often due to inadequate climate control, need to be addressed to ensure efficient distribution and safeguard food's nutritious quality.

This waste contributes significantly to GHG emissions, emphasizing the vital need to reduce food waste globally.

Steps Towards a Solution to Reducing Food Waste

Collaborate with Food Banks: Excess food from restaurants and food manufacturers can be rescued and redistributed through food banks, ensuring that edible food reaches those in need.

Empower Local Governments: Local authorities and governments play a crucial role in creating regulations and incentives to reduce food waste. Offering discounted prices for excess food or tax incentives for food donations can be effective.

Educate and Innovate: About 90% of countries have integrated education for sustainable development into their curriculum. This initiative can include food waste prevention strategies, teaching the next generation the importance of reducing wasted food.

Enhance the Food Production Supply Chain: Investing in technology and infrastructure can minimize food losses in the production and supply chains. Innovations that help store or distribute food properly will significantly reduce wasted food.

Tackling E-Waste: While e-waste is a different challenge, it’s noteworthy that in 2019, only 1.7 kilograms of the 7.3 kilograms of e-waste generated per capita globally was managed responsibly. This shows a broader pattern of wastage that extends beyond food and indicates a pervasive need for sustainable practices across all sectors.

Practical Steps to Reducing Food Waste in Restaurants

1. Inventory Management: Modern software can help restaurants accurately forecast demand and order supplies.
2. Staff Training: Equip staff with the knowledge and tools to minimize waste.
3. Consumer Education: Inform patrons about portion sizes and offer 'doggy bags.'
4. Collaboration: Work with food banks or other organizations to donate unsold food.
5. Sustainability Certifications: Consider obtaining certifications like the Zero Waste certification to demonstrate commitment and drive change.

Conclusion

Food waste is a multi-faceted challenge affecting every stage of the food production chain, from farms to dining tables. As we aim for sustainable economic growth and improved food security, addressing food waste becomes not just an environmental imperative but a moral and economic one. Collaborative efforts among food manufacturers, food service providers, local governments, and consumers are essential in aligning with the United Nations' Sustainable Development Goals.
