The Multifaceted Causes of Food Waste
Food waste in Singapore stems from a combination of factors across the supply chain, from production to consumption. Despite campaigns by the National Environment Agency (NEA) and other bodies, ingrained habits in homes and businesses pose significant obstacles to reducing waste.
Commercial and Industrial Contributors
The commercial and industrial sectors contribute around 40% of Singapore's food waste. Several practices within these sectors lead to this:
- Cosmetic Filtering: Due to Singapore importing over 90% of its food, strict appearance standards for produce result in edible but 'ugly' items being discarded at various stages to meet consumer expectations for perfect-looking food.
- Over-ordering and Inventory Issues: The competitive F&B industry often over-orders ingredients to avoid shortages. Bakeries may also overstock for display, leading to excess food being thrown away daily.
- Liability Concerns for Donation: Although the Good Samaritan Food Donation Bill was introduced to encourage donations, businesses previously worried about potential liability when donating surplus food. Shifting cultural and legal perceptions will take time.
Household Habits and Societal Norms
Households are also major contributors to food waste, often due to daily habits and cultural norms:
- Overbuying and Improper Storage: Many households buy more groceries than they can consume before spoilage. Incorrect storage methods also accelerate this process.
- Misunderstanding Expiry Dates: People often discard food immediately after the 'best-before' date, even if it's still safe. This reliance on labels instead of checking the food itself contributes significantly to waste.
- Leftovers from Dining Out: Cultural practices, particularly at large events and buffets, encourage excessive food portions. Finishing all the food can be seen as impolite, resulting in high plate waste at F&B establishments.
Comparison of Household vs. Commercial Food Waste Factors
| Factor | Household Food Waste | Commercial/Industrial Food Waste |
|---|---|---|
| Primary Cause | Overbuying, improper storage, misunderstanding labels, cultural norms regarding leftovers. | Cosmetic filtering, over-ordering, poor inventory control, and overproduction. |
| Contributing Culture | Desire for abundance and pristine appearance; hesitancy to take home leftovers from dining out. | High consumer demand for flawless produce; economic pressure to avoid stock-outs. |
| Waste Type | Uneaten food, expired products, food preparation scraps. | Imperfect produce, manufacturing scraps, expired inventory, plate waste from diners. |
| Potential Solution | Public education, meal planning apps, home composting guides. | Mandatory waste segregation, tech-driven inventory tracking, donation programs. |
The Environmental and Social Impact
Large amounts of food waste have severe consequences for Singapore.
- Landfill Strain: Singapore's only landfill, Semakau, is filling up quickly, and food waste contributes significantly to this. Incinerating food waste, the main disposal method, also uses considerable energy.
- Greenhouse Gas Emissions: Decomposing food waste in landfills releases methane, a potent greenhouse gas contributing to climate change.
- Resource Depletion: Wasting food means wasting the resources used to produce it, which is particularly impactful for an import-dependent nation.
- Food Insecurity: The presence of extensive food waste alongside food insecurity highlights a societal imbalance that could be partially addressed by redistributing surplus food.
Moving Forward: Tackling the Root Causes
Singapore's 'Zero Waste Masterplan' and NEA initiatives provide a framework for addressing food waste, but consistent effort from everyone is needed.
Key Strategies for Reduction
- Mandatory Segregation: Large commercial and industrial facilities must segregate food waste for better treatment and recycling.
- Infrastructure Investment: Facilities like the upcoming Tuas Nexus will treat food waste to produce biogas. New buildings are also required to include space for on-site treatment.
- Encouraging Redistribution: The Good Samaritan Food Donation Bill protects donors, encouraging them to give excess food to charities.
- Technology and Innovation: Tools like 'Smart Dustbins' track waste in F&B outlets to improve inventory, and initiatives find ways to convert food waste into useful products.
- Targeted Public Education: Campaigns target specific behaviors, like finishing food at canteens, and educate consumers on date labels and proper storage.
Conclusion
Food waste persists in Singapore due to a mix of systemic and behavioral factors. While government policies and infrastructure are being developed, tackling the issue long-term requires changes in cultural norms and individual actions. By addressing commercial practices and promoting mindful consumption, Singapore can make progress towards becoming a Zero Waste Nation.
