29 Sep International Day of Awareness of Food Waste: a global challenge
Every September 29, the world marks the International Day of Awareness of Food Waste, promoted by the UN and FAO to highlight a daily issue with deep environmental, economic, and social consequences.
Why is food waste a problem?
Food waste is not just about “throwing food away”: it means wasting resources such as water, energy, land, and human labor. It is estimated that one-third of all food produced worldwide ends up in the trash, creating economic losses and unnecessary pressure on ecosystems.
Environmental and social impacts of waste
Food waste accounts for a significant share of global greenhouse gas emissions along the entire chain (production, transport, storage, and disposal). At the same time, while millions of tons of food are discarded, millions of people face food insecurity. Reducing food waste is therefore both an environmental and social justice action.
SDG 12: responsible production and consumption
SDG 12 calls for sustainable patterns of production and consumption. Reducing losses and waste throughout the agri-food chain is one of its key goals. This involves better purchase and storage practices, innovation in processes, partnerships with social organizations, and responsible waste management when food cannot be recovered.
Practical solutions for homes and businesses
The good news: there are concrete and achievable actions.
At home
- Plan meals and shopping to avoid excess.
- Apply FIFO (first in, first out) in your fridge and pantry.
- Use leftovers in new recipes and freeze portions.
- Separate organics for composting whenever possible.
In restaurants and businesses
- Monitor waste by station/shift and adjust portions.
- Train staff on safe storage and date labeling.
- Donate surplus food in good condition to food banks.
- Implement traceability and valorization routes for inedible waste (compost, biogas, by-products).
How Greenside contributes to this challenge
At Greenside Solutions, we turn waste management into a tool against food waste:
- Environmental management portal to record and trace flows (organics, packaging, oils, etc.).
- Dashboards to visualize trends and make informed decisions.
- Consulting to implement operational improvements and measure impact (emissions avoided, savings, SDG compliance).
“Reducing food waste is not only an environmental responsibility: it is also an act of efficiency and social justice.”
Conclusion
Food is worth more than its price tag: it is water, energy, time, and land. Acting today—at home and in businesses—means moving towards a more efficient, resilient, and fair food system. September 29 is a reminder; real change happens every day.
