Introduction

Addressing food waste is essential for environmental sustainability. Food waste is a major environmental problem that must be eradicated to alleviate climate change. Reducing food waste lowers costs, generates profits, and helps mitigate climate change. Becoming a "food waste hero" involves adopting practices that minimize waste and promote a sustainable approach to food consumption.

The Problem of Food Waste

• Environmental Impact:
• Food waste significantly contributes to greenhouse gas emissions. When organic waste decomposes in landfills, it produces methane, a potent greenhouse gas. Methane traps far more heat in the atmosphere than carbon dioxide, exacerbating global warming .
• The production of food requires substantial resources, including water and energy. When food is wasted, these resources are squandered. Reducing food waste conserves these precious resources and lessens the environmental burden.
• Food waste leads to long-lasting environmental effects, including resource depletion and increased food insecurity.
• Global Statistics:
• In 2019, 931 million tonnes of food were wasted by households, retailers, restaurants, and other food services.
• Food waste accounts for approximately 10% of the total waste generated in Singapore.
• Globally, one-third of the food produced is lost or wasted.
• Economic Costs:
• Food waste results in significant financial losses for businesses and households.
• In Australia, 7.6 million tons of food are wasted annually, costing $36.6 billion .

Key Sources of Food Waste

• Consumer Level:
• Around 61% of food waste occurs within households, making consumers a primary source of the problem.
• Consumer habits, such as buying more food than needed, failing to use food before it spoils, and serving overly large portions, contribute to this waste.
• Retail and Supermarkets:
• Supermarkets play a significant role in tackling food waste by guiding consumer behavior and implementing waste-reduction strategies.
• Initiatives such as selling "wonky" or imperfect fruits and vegetables encourage consumers to buy produce that might otherwise be discarded due to cosmetic imperfections .
• Food Service Industry:
• Restaurants, hotels, and canteens also generate substantial food waste due to overproduction, large portion sizes, and inefficient inventory management .

Strategies for Reducing Food Waste at Home

• Meal Planning:
• Meal planning helps streamline grocery shopping, ensuring that only necessary items are purchased and used. By planning meals in advance, consumers can reduce impulse buys and minimize the risk of food spoilage.
• Love Your Leftovers:
• Creative use of leftovers can significantly reduce waste.
• Freezing extra portions for future meals ensures that food is not left to spoil. Vegetable and herb scraps can be used to make soups and broths, maximizing their utility.
• Proper Food Storage:
• Storing food correctly helps extend its freshness and prevents spoilage.
• Some foods should not be stored together because they interact and accelerate spoilage.
• Composting:
• Composting food scraps and unavoidable food waste, such as fruit and vegetable peels, reduces landfill waste and creates nutrient-rich compost for gardens .
• Options include garden composting and curbside composting programs offered by local municipalities .
• "Use-it-Up" Shelf:
• Designating a specific shelf in the refrigerator for items that need to be used soon helps ensure that these foods are prioritized and consumed before they spoil.

How Businesses Can Reduce Food Waste

• Advanced Inventory Management:
• Businesses can prevent food waste through advanced stock control and inventory management systems.
• Artificial intelligence (AI) and machine learning can optimize supply chains and improve demand forecasting, reducing overstocking and waste.
• Enhanced Donation Efforts:
