One-fifth of food produced for human consumption is lost or wasted globally, amounting to one billion meals a day and costing the global economy roughly US$1 trillion. These statistics give us valuable insight into the food waste crisis, demonstrating the importance of reducing waste to achieve greater sustainability and global food security.
From turning food waste to energy to implementing circular economy frameworks, there are different approaches that businesses and governments can implement to reduce dependence on landfills. Keep reading to learn about the technologies and strategies driving this change.
Key Technologies Driving Food Waste Transformation
New technologies are constantly emerging. It should come as no surprise, then, that modern tools and solutions are transforming traditional waste management processes.
Let’s take a look at how anaerobic digestion, composting innovations, and artificial intelligence (AI) are key solutions for reducing food waste.
Anaerobic Digestion
Anaerobic digestion is a biological process in which bacteria break down organic matter in an oxygen-free environment. While this process occurs naturally in environments like marshes and swamps, it can also be carried out on a large scale using enclosed vessels called anaerobic digesters.
This process produces biogas, a renewable energy source, and digestate, a nutrient-rich material that can be used as fertilizer. The environmental benefits of anaerobic digestion include diverting waste from landfills, generating renewable energy, improving soil health, and reducing methane emissions.
Composting Innovations
Composting is the biological decomposition of organic materials by microorganisms in the presence of oxygen. In addition to reducing waste, composting decreases methane emissions from landfills, improves plant health, and supports sustainable agriculture.
While traditional systems don’t require technology, innovations in composting technology help turn organic waste into compost on a much larger scale.
Automated composting systems monitor and manage factors like temperature and microbial activity to accelerate decomposition. In-vessel composting is another useful innovation, using technology and a controlled environment to enhance the composting process for commercial or community waste.
AI-Powered Technology
AI optimizes a range of processes across the supply chain, helping reduce waste and increase efficiency.
Here are 3 ways companies are using AI today:
- Smart bins and sensors: Companies use AI-powered bins and sensors to identify patterns, gain real-time insights into how waste is generated, optimize collection schedules, and reduce sorting errors—all of which enhance overall waste management.
- Predictive analytics: Grocery stores, restaurants, and manufacturers use predictive analytics to improve demand forecasting, optimize inventory, and enhance supply chain efficiency.
- Computer vision for automated sorting: AI-powered image recognition systems help identify food waste, separate edible from non-edible items, and improve sorting accuracy in real time, allowing companies to recover more usable materials and reduce overall waste.
Strategic Approaches for Managing Food Waste
In addition to adopting innovative technology, there are different strategies that can be implemented on a global scale to reduce waste.
Circular Economy Frameworks
The goal of a circular economy is to keep products and materials in circulation for as long as possible. The Ellen MacArthur Foundation recognizes three key principles of a circular economy: eliminating waste and pollution, circulating products and materials at their highest value, and regenerating nature.
There are many ways a circular economy can be put into practice. For instance, a company may redesign its products using sustainable materials and implement a recycling program to increase resource efficiency. A local government, on the other hand, may invest in infrastructure to support circular activities, such as an anaerobic digestion facility.
Policy and Regulatory Initiatives
Food waste regulations play a critical role in reducing waste. Various initiatives help increase awareness and minimize waste, such as extended producer responsibility, landfill taxes, organic waste bans, incentives for food waste-to-energy initiatives, and more.
While existing regulations help raise awareness of the food waste crisis, additional initiatives are needed to drive lasting, large-scale change.
Increased Public Awareness
Unfortunately, there’s still a widespread lack of knowledge about the food waste crisis. While many people want to support sustainability initiatives, they often lack the tools or awareness needed to make meaningful changes.
Educational campaigns and local initiatives are key to increasing awareness and getting more people involved. For instance, curbside composting programs help households divert food from landfills, while an increase in local infrastructure helps companies manage waste more effectively.
Benefits of Enhanced Food Waste Management
The technologies and strategies discussed above can help countries and companies around the world reduce food waste. Why is this important?
The benefits can be broken down into three main categories:
- Environmental: Reducing food waste has an array of environmental benefits. From reducing greenhouse gas emissions to conserving natural resources and minimizing pollution, strategies like composting and adopting a circular economy contribute to a more sustainable world.
- Economic: As mentioned, food loss and waste cost the global economy an estimated USD 1 trillion each year. These losses affect households and companies alike, meaning those that implement waste-reduction strategies can significantly minimize the financial impact. Even more, companies have the opportunity to create new revenue streams by turning waste into useful resources like energy, compost, and animal feed.
- Social: An estimated 673 million people faced hunger in 2024. At the same time, one billion meals are wasted every single day. By reducing waste through initiatives like donation programs, you can ensure surplus food goes to those in need, supporting communities and contributing to a more sustainable food system.
Final Thoughts
Food waste is a multifaceted issue. Every country has its own challenges, infrastructure requirements, and policies leading these efforts.
When combined with the unique obstacles faced by companies across the supply chain, it becomes clear why food waste reduction remains such a complex challenge. For that reason, it’s important to remember that there’s no one-size-fits-all solution; every government, company, and household must evaluate their specific challenges and goals and create a strategy that works for them.
Whether your household is embracing an AI-powered meal planning app to cut down on waste or your company is partnering with a waste management provider to support an anaerobic digestion project, every effort matters.
So ask yourself: Can emerging technologies help you reduce waste? How might implementing a circular economy framework benefit you?
