Food Waste in Supply Chains

Did you know that every year, millions of tons of food are wasted along the supply chain, from farm to fork? It’s a shocking reality that not only impacts our environment but also contributes to global hunger and economic losses. Discover the hidden truth behind food waste in supply chains. Food waste is a global challenge that affects not only our environment but also our economy and social well-being. Within the complex web of food production, distribution, and consumption, supply chains play a crucial role in determining how much food is lost or wasted.  

According to McKinsey, 33% to 40% of the world’s food is lost or wasted every year, yet one in nine of the world’s population can’t get enough to eat—that’s equivalent to 800 million suffering from hunger.

Food Waste in Supply Chains 

At every stage of the food chain, from production to consumption, food waste is a serious problem. Harvest, storage, processing, sale, and consumption are all parts of the supply chain where food that is still edible may be disposed of.  

Food waste is a silent epidemic that lurks at every turn of the supply chain, stealthily siphoning off precious resources and contributing to environmental degradation. At the production stage, farms witness the heartbreaking sight of imperfect produce being cast aside, surplus crops left to rot, and post-harvest losses silently eroding hard-earned yields. Processing facilities, despite their best efforts, witness inefficiencies during processing and packaging, leading to the heartbreaking sight of perfectly edible food ending up in the waste bin. During distribution, the journey from farm to fork becomes a perilous one, with transportation woes, storage mishaps, and mishandling culminating in the untimely demise of food items. Even in the hallowed halls of retail, where shelves groan under the weight of abundance, overstocking, stringent expiration dates, and the tyranny of cosmetic standards conspire to sentence perfectly good food to an ignominious fate. And alas, at the final frontier of consumption, where food meets its intended destiny, consumers grapple with confusion over labels, succumb to the whims of impulse purchases, and fall prey to the scourge of lacklustre meal planning, unwittingly contributing to the ever-swelling tide of waste. From farm to fork, each stage of the supply chain bears witness to the tragic saga of food waste, underscoring the urgent need for concerted action to stem the tide and build a more sustainable food system for generations to come. 

Agriculture and food supply chain disruptions can have great impacts on food security, economic stability and social well-being.

What is the Difference between Food Waste and Food Loss? 

Food waste and food loss are related concepts but have distinct meanings: 

Food Loss: 

• Food loss refers to the decrease in edible food mass throughout the supply chain leading to edible food not being available for human consumption. 
• It typically occurs during production, post-harvest handling, and storage stages of the food supply chain. 
• Factors contributing to food loss include poor agricultural practices, inadequate infrastructure, inefficient harvesting techniques, and improper storage conditions. 
• Food loss often occurs in developing countries where infrastructure and technology for food preservation and distribution are lacking. 

Food Waste: 

• Food waste refers to edible food that is discarded at any stage of the supply chain, including production, processing, distribution, and consumption. 
• It includes food that is thrown away by households, restaurants, supermarkets, and other food establishments. 
• Food waste can occur due to factors such as overproduction, expiration dates, cosmetic standards, consumer behavior, and inefficient inventory management. 
• Food waste is prevalent in both developed and developing countries, although the reasons and patterns may vary. 

In summary, food loss occurs primarily during the early stages of the supply chain before food reaches consumers, while food waste occurs at various stages of the supply chain and includes food discarded by consumers and food establishments. 

The Impact of Food Waste 

In India, 67 million tonnes of food are wasted and about 70-75% of food waste rots in landfills.   

Food waste is a problem that has big environmental effects. When food is wasted, the resources of land, water, energy, and labour used to generate it are also lost. Due to this, water use, deforestation, and greenhouse gas emissions rise unnecessarily, all of which contribute to climate change and biodiversity loss.  

“Food waste is an ethical outrage”, stated UN’s Secretary-General, António Guterres on UN’s designated International Day for the Awareness of Food Waste and Loss 

The connection between food waste and global warming lies in the significant amount of greenhouse gas emissions produced throughout the food supply chain, from production and distribution to consumption and disposal. When food goes to waste, all the resources used in its production such as water, energy and land are also wasted along with th e emissions generated. Global warming is significantly exacerbated by food waste. When food is wasted, it ends up in landfills where it decomposes and generates methane, a powerful greenhouse gas that has a 25-fold greater effect on global warming than carbon dioxide. 

According to the UN, after China and the United States, food waste would be the third-largest producer of greenhouse gases if it were a nation. 

The Environmental Impact  

The environmental impact of food waste is significant and multifaceted: 

Greenhouse Gas Emissions: 

   – When food waste is sent to landfills, it decomposes anaerobically, releasing methane, a potent greenhouse gas that contributes to climate change. 

   – Methane has a much higher global warming potential than carbon dioxide, making it a significant contributor to climate change. 

The food industry is responsible for 8-10% of the total Greenhouse gas emissions. 

Resource Depletion: 

   – Food production requires vast amounts of resources such as water, land, energy, and nutrients. When food is wasted, these resources are also wasted, leading to inefficient resource allocation and depletion. 

   – For example, agriculture accounts for a large portion of freshwater usage globally, and wasted food represents a loss of water resources used in its production. 

Biodiversity Loss: 

   – Agricultural expansion for food production can lead to habitat destruction and biodiversity loss, as natural ecosystems are converted into farmland. 

   – When food is wasted, it not only represents a loss of resources but also contributes to the demand for more agricultural land, exacerbating the pressure on natural habitats. 

Energy Consumption: 

   – Food production, processing, transportation, and storage require significant energy inputs. When food is wasted, the energy invested in its production and distribution is also wasted, leading to unnecessary energy consumption and associated environmental impacts. 

Landfill Pollution: 

   – Food waste disposed of in landfills contributes to landfill pollution, including leachate runoff and soil and water contamination. These pollutants can have adverse effects on ecosystems and human health. 

Overall, addressing food waste is essential for mitigating its environmental impact and promoting sustainability across the food system. Reducing food waste can help conserve resources, reduce greenhouse gas emissions, protect biodiversity, and minimize pollution. 

The Economic and Social Impacts 

The economic and social impacts of food waste are profound: 

Economic Losses: 

   – Food waste represents a significant economic loss throughout the supply chain, from production to consumption. 

   – Farmers incur losses due to wasted inputs such as labor, water, and fertilizers, as well as unsold or discarded crops. 

   – Food manufacturers and retailers lose revenue on unsold products, and additional costs are incurred for waste disposal. 

   – Consumers waste money on purchased food that is ultimately thrown away, contributing to household expenses. 

Increased Costs: 

   – Food waste leads to increased costs for waste management, transportation, and landfill disposal. 

   – Businesses incur expenses associated with handling, storing, and disposing of wasted food, impacting their profitability. 

   – Municipalities and governments bear the costs of waste collection and disposal, diverting resources from other essential services. 

Food Insecurity: 

   – While food is wasted at various stages of the supply chain, millions of people worldwide suffer from food insecurity and hunger. 

   – The resources wasted on food production and distribution could have been redirected to alleviate hunger and improve food access for vulnerable populations. 

Environmental Degradation: 

   – The environmental impacts of food waste, such as greenhouse gas emissions and resource depletion, also have economic consequences. 

   – Environmental degradation can lead to reduced agricultural productivity, increased production costs, and disruptions to supply chains, affecting livelihoods and economic stability. 

Social Equity: 

   – Food waste exacerbates social inequalities by perpetuating disparities in access to food and resources. 

   – Vulnerable communities, including low-income households and marginalized groups, are disproportionately affected by food insecurity, while excess food is wasted elsewhere. 

Overall, addressing food waste is crucial for promoting economic prosperity, social equity, and environmental sustainability. By reducing waste and improving resource efficiency, societies can create more resilient and equitable food systems for all. 

Why Companies need to Reduce Food waste? 

Reducing food waste is imperative for companies aiming to achieve sustainability objectives, as it not only supports environmental goals but also contributes to social targets. SDG 12.3, for instance, urges a reduction in food waste by half by 2030, aligning with broader aims such as SDG 2, Zero Hunger. Many major food corporations, including Nestlé, have committed to reducing food waste as a core sustainability objective, achieving significant milestones in waste reduction.  

In response to the climate crisis, sustainability goals have become essential for businesses, with stricter regulations emerging globally. The EU, for example, has implemented binding targets to reduce food waste, while Sweden has set ambitious strategies for halving food waste by 2030.  

Crucial to achieving these objectives is the ability to measure progress accurately using quality data. Sustainability management solutions play a key role in this regard, enabling companies to monitor their sustainability efforts and align with frameworks such as the SDGs effectively.
