What is the best way to prevent food waste? 

There are numerous strategies that businesses can explore based on their specific needs and goals. Keep reading to learn more about popular waste management approaches and how different sectors can implement them. 

1. Better Forecasting & Demand Planning 

One of the keys to minimizing food waste is to align production and purchasing with real consumer demand. By improving demand forecasting, businesses can avoid overstocking and overproducing, therefore reducing spoilage. 

To enhance demand planning, organizations can leverage tools like data analytics and AI to predict customer demand more precisely. 

Benefiting sectors: 

• Restaurants: To reduce food waste in restaurants, establishments can use tools to track seasonal trends, weather, and economic factors to prevent overstocking and better understand which dishes are in high demand. 
• Supermarkets: Supermarkets can use advanced systems to monitor sales and inventory patterns, preventing overstocking and reducing food waste at grocery stores.  
• Food producers: Producers can adjust their production levels and resource allocation by having a deeper understanding of the anticipated demand, therefore preventing overproduction. 

2. Improving Storage and Preservation to Prevent Food Spoilage 

Another way to minimize food waste is to improve storage methods, therefore helping extend the shelf life of products. There are various ways that businesses can do this, such as investing in temperature-controlled storage, smart packaging, and advanced monitoring systems.  

In addition, businesses that use AI to prevent food waste in storage can monitor temperature and humidity levels in real-time, enabling them to address potential issues quickly and prevent waste at the source. These strategies can be utilized throughout the supply chain—from production to retail—to maintain food quality and prevent spoilage. 

Benefiting sectors: 

• Food producers: Producers can invest in climate-controlled storage facilities to prevent spoilage before products reach retailers. 
• Supermarkets: Supermarkets can implement smart shelves that track expiration dates and trigger alerts when products near their sell-by date. 
• Food distributors: Distributors can use temperature sensors in refrigerated trucks to ensure products remain fresh during transit. 

3. Portion Control 

In addition to reducing plate waste, serving more accurate portion sizes also helps food establishments maintain quality and optimize inventory management. Restaurants can improve portion control and minimize food waste by analyzing consumer consumption patterns and offering flexible portion sizes. 

Benefiting sectors: 

• Restaurants: Restaurants can improve profitability while catering to customer preferences by implementing smaller portion options or customizable serving sizes to reduce plate waste. 

4. Partnering with Food Donation Programs 

While there are many tips to prevent food waste, collaborating with local food banks or nonprofit organizations is among the most beneficial to the community. In addition to preventing food waste, donations help reduce food insecurity, minimize disposal costs, and help businesses potentially gain food waste tax deductions.  

Businesses can use apps to reduce food waste that are designed to facilitate donation efforts, helping them donate surplus, unsellable—but still safe—food items. The Bill Emerson Good Samaritan Food Donation Act has significantly encouraged these efforts by providing legal protection to businesses that donate food in good faith.
