How to Reduce Food Waste at Home: 7 Habits That Actually Stick

Household food waste isn't a cooking problem — it's a memory problem. Most of what gets thrown out was perfectly good food that was simply forgotten until too late. That's good news, because forgetting is fixable.

1. Track expiry dates automatically

The single highest-impact habit. Food gets wasted when its date passes unseen; a reminder a week before turns “bin it” into “build dinner around it”. The habit only sticks if recording is effortless — with RiScan you scan the printed date with your camera and photograph the product, about ten seconds per item. The app then keeps track of the dates and notifies you in time.

2. Shop from your inventory, not your imagination

Duplicate purchases are quiet waste: the second jar of curry paste bought because you forgot the first. Before shopping, glance at your list — if it's in an app, it's in your pocket at the store. A pantry inventory pays for itself in avoided doubles alone.

3. Give “eat me first” a physical shelf

Keep one basket or shelf corner in the fridge for items expiring soon. When RiScan tells you something has a week left, move it there. Anyone cooking starts from that shelf.

4. Learn what the dates actually mean

“Best before” is a quality date, not a safety cliff — plenty of food is fine after it. “Use by” is the hard safety line. Knowing the difference (see best before vs. use by) stops both kinds of mistake: binning good food and risking bad food.

5. Store food where it lasts

• Bread: freezer beats fridge (fridge accelerates staling).
• Potatoes, onions, garlic: cool, dark, dry — not the fridge, and not next to each other.
• Herbs: like flowers, in a glass of water.
• Opened jars and sauces: note that “refrigerate after opening, use within X days” often matters more than the printed date.

6. Make a weekly “use-it-up” meal

One dinner a week — stir-fry, frittata, soup, fried rice — built entirely from whatever is expiring. With a list sorted by urgency, the menu writes itself: open RiScan, see what's yellow and orange, cook that.

7. Buy the awkward sizes on purpose

The half-price large pack is only a bargain if you finish it. If you do buy big, split and freeze half on day one — and scan the frozen half too, with the date you want to be reminded by.

Start with habit #1 — it carries the rest. RiScan is free for iPhone and iPad.

What it adds up to

Estimates of household food waste consistently land in the range of hundreds of euros per household per year, and a large share of it is preventable “forgotten food”. You don't need all seven habits on day one. Scan tonight's groceries, let the reminders arrive, and let the system prove itself one saved dinner at a time.
