How to Reduce Food Waste at Home

The average person throws away 30 kg of food per year, including 7 kg still in its packaging. That's $100 to $160 per person going in the trash. Beyond the wallet, it's a huge waste of resources (water, energy, farmland). The good news: 5 simple changes reduce your waste by 50 to 70%.

Steps

1

Audit your current waste

For one week, note everything you throw away: the wilted salad, the expired yogurt, forgotten leftovers. You'll be surprised by the trends. Most people always waste the same things: fresh produce bought in excess, bread, and unfinished meal leftovers.

2

Plan your meals around what you have

Before planning your weekly menu, open your fridge and cupboards. That half-onion, that piece of celery, and that can of tomatoes become the base of a meal. Plan 1-2 'fridge-clearing' meals per week specifically to use up leftovers and products nearing their end.

3

Master FIFO storage

FIFO = First In, First Out. When you put away your groceries, place the oldest products in front and the new ones in the back. It sounds basic, but it eliminates 90% of those 'I forgot that was there' moments. Apply the same logic to the freezer: label and date everything.

4

Learn to use leftovers creatively

Leftover cooked vegetables become a frittata, a soup, or a gratin. Stale bread makes French toast, breadcrumbs, or croutons. Overripe fruit can be turned into a smoothie, compote, or banana bread. There is no such thing as 'food waste' — only ingredients waiting for an idea.

5

Freeze before it expires

As soon as a food item approaches its expiration date, freeze it. Bread freezes perfectly slice by slice. Meat and fish should be frozen on the day of purchase if you don't plan to use them within 2 days. Chopped fresh herbs can be frozen in ice cube trays with a little oil.

Food waste in France: the numbers

France wastes about 10 million tons of food per year, or 150 kg per person across the entire food chain. Households are responsible for 33% of this waste. Fruits and vegetables are the primary category thrown away, followed by leftover meals and bakery products. In value, it's between $100 and $160 per person per year going in the trash. The 2016 Garot law prohibits supermarkets from throwing away unsold items, but at home, it's your organization that makes the difference.

Creative zero-waste recipes

Carrot top soup: the greens have as many nutrients as the carrots themselves. Veggie peel chips: potatoes, beets, parsnips — olive oil, salt, oven at 180°C for 15 min. Leek green pesto: the green part we often throw away makes an intense and flavorful pesto. Homemade stock: all the vegetable scraps accumulated in a bag in the freezer become a rich broth in 45 min of simmering. These recipes aren't a sacrifice — they're often better than the 'standard' version.

Composting, the last line of defense

Since January 1, 2024, sorting bio-waste has been mandatory in France. If your local council offers composting bins or separate collections, take advantage of it. For an apartment, a worm farm or a bokashi takes up less than one square meter and won't smell if managed correctly. Peels, coffee grounds, eggshells, and vegetable scraps turn into potting soil in 3-6 months. It's the ultimate solution for the little food waste that remains after applying the 4 previous steps.

Batch cooking reduces waste structurally

By planning your meals and cooking in batches, you buy exactly what you need. No surplus rotting in the back of the fridge. Ingredients are used in multiple recipes and leftovers are portioned and frozen by Sunday. Waste naturally drops from 30% to less than 5%.

Frequently Asked Questions

Use-by vs Best-before: what's the difference?
The DLC (Use-By Date, 'to be consumed until') concerns fresh and perishable products: pass it and there is a health risk. The DDM (Best-Before Date, 'best before') concerns dry products, cans, and frozen foods: after this date, the product may lose taste or texture but remains safe.
Can you freeze food that has already been thawed?
No for raw products. But if you have thawed meat and cooked it, you can freeze the cooked dish without any problem. The rule: never refreeze a thawed raw product, but a cooked product after thawing is fine.
How do you know if food is still good?
Three senses are enough. Appearance: visible mold, abnormal color, cloudy liquid → trash. Smell: sour, rancid, or 'weird' smell → trash. Texture: slimy, viscous when it shouldn't be → trash. When in doubt, throw it out. Food poisoning costs more than the wasted food.
Does food waste have a real environmental impact?
Huge. If global food waste were a country, it would be the 3rd largest emitter of greenhouse gases after China and the USA. Producing food that gets thrown away wastes 250 km³ of water per year and occupies 1.4 billion hectares of agricultural land for nothing.
