Before questioning the importance of food waste management, it is essential to ascertain the definition of food waste. Are the rotten vegetables and fruits that are discarded considered as food waste? Or is the chocolate bar that is thrown away considered food waste? Well, the answer to this question is that both are classified as food waste. The Food and Agriculture Organization of the United Nations defines food waste as “food appropriate for human consumption being discarded, whether it’s kept beyond its expiry date or left to spoil”.
Food waste management refers to the process of efficiently handling, recycling or disposing of food waste generated at various stages of the food supply chain. It involves the implementation of strategies to reduce, reuse, and recycle food waste to minimize its environmental impact. Proper food waste management aims to address the significant issues of food loss, environmental pollution, and resource depletion.
The global food waste management market is expected to grow at a CAGR of 5.4% from 2023 to 2028. The food waste management market is growing due to increasing awareness of food waste's environmental impact. Strategies include reducing, recycling, and repurposing waste at various levels. Anaerobic digestion and composting are popular methods for recycling food waste, but they require space, generate volatile organic chemicals, and consume energy. Anaerobic digestion decomposes biodegradable waste without oxygen, producing renewable energy or biogas. The rise in global food waste is attributed to increased food production to meet population demands, but inefficiencies in the supply chain and inadequate infrastructure contribute to waste. For instance, the Food and Agriculture Organization of the United Nations (FAO) estimates that the world population will reach 9.7 billion by 2050.
Food waste management involves prevention, distribution, reuse, recycling, and disposal, promoting sustainable farming practices, reducing wastage, and utilizing environmentally friendly methods for disposal. The components of food waste management are as follows:
Food waste presents a critical global issue, contributing significantly to climate change by releasing greenhouse gases, mainly methane, from landfill disposal. This excess food wastage poses ethical challenges, especially considering widespread global food insecurity. Addressing food waste is crucial not only for environmental sustainability but also for ensuring equitable access to food, making it a paramount concern for global food security.
Food loss results in significant economic losses for farmers, food producers, and distributors, leading to reduced income and financial instability, particularly in developing countries where agriculture is a major source of livelihood.
The key players operating in the global food waste management market are Veolia, Suez, Waste Management, Inc., Republic Services, Inc., Covanta Ltd., Stericycle, Inc., Remondis SE & Co., KG, Clean Harbors, Inc., and Biffa, among others.
As the issue of food waste continues to persist, the world must come up with solutions to manage food waste. Some of the possible solutions are as follows.
The above are some of the solutions that will help in reducing food waste and achieving a sustainable food practice for the future.
Food waste management is a global concept and different countries have adopted different approaches to deal with food waste. The situation of food waste management in different regions of the world are as follows.
In conclusion, the global challenge of food waste demands urgent and comprehensive action, with the need for efficient food waste management practices becoming increasingly imperative. While the consequences of food waste reverberate across diverse sectors, including the economy, environment, and social well-being, collaborative efforts between governments, businesses, and communities are crucial to implementing sustainable solutions. The world can strive towards a more sustainable and equitable future for food production and consumption by prioritizing responsible consumption, innovative recycling methods, and supportive policy frameworks.
