Food Waste: 5 Tips to Reduce Waste and Leftovers
Imagine this: you come home after a long day, open the fridge, and realize that the bunch of spinach you bought with the best intentions is wilted, the milk has expired, and yesterday’s bread is too hard. What do you do? If your first reaction is to throw everything in the trash, you’re not alone. But here’s the problem: that small action, repeated in millions of households, contributes to a global issue affecting both the environment and our wallets. The good news is that we can change this—we can reduce food waste.
Adopting a zero-waste kitchen isn’t just an Instagram trend; it’s a real necessity in a world where food waste is one of the leading causes of pollution and resource depletion. But this isn’t about feeling guilty—it’s about finding practical and sustainable solutions to make our food consumption more efficient and responsible. How can we reduce food waste at home? Let’s take a look.
1. Planning: the key to a waste-free home
How can you prevent food waste? The best way is to plan your meals, make a shopping list, and check your pantry before you buy. This way, you only purchase what you actually need and use up products before they expire.
Most food ends up in the trash not because we want to waste it, but because we forget to use it in time. A small change in mindset can make a huge difference: shop strategically, not impulsively.
Before heading to the supermarket, think about what you’ll be cooking during the week. This doesn’t mean rigid and boring meal planning, but having a general idea to avoid buying unnecessary items. Have you noticed that when you shop without a list, you end up with products you don’t even remember why you grabbed? Planning helps you spend less and use everything you already have at home.
A useful trick is to take a quick inventory of your fridge and pantry before shopping. This way, you ensure you don’t buy duplicates and prioritize items that are close to expiring. You can also try mobile apps that help manage your food stock and suggest recipes based on what you have available.
Additionally, buying in bulk and opting for fresh seasonal products not only reduces environmental impact but also improves the taste of your food. Less packaging, fewer preservatives, and more authentic flavor.
2. Food storage: the secret to reducing food waste
Did you know that placing certain foods in the wrong part of the fridge can make them spoil faster? For example, tomatoes and potatoes last longer outside the refrigerator, while fresh herbs can be kept like flowers, in a glass of water in the fridge. A small adjustment in how we store food can double its shelf life.
The Japanese refrigerator organization method suggests using transparent trays to make everything visible at a glance and avoid forgotten items in the back. If what’s out of sight doesn’t get used, then let’s make it visible. The same applies to the pantry: place older items in front and newly bought ones behind. A simple organization method can prevent kilos of waste each year.
Another useful tip is to label containers with expiration dates. We often forget when we opened a product and discard it just to be safe. Writing the date on the lid with a marker can help avoid this problem.
And if something is close to expiring, prioritize it. You can create a dedicated section in your fridge for foods that need to be used soon, making them the first thing you see when cooking.
3. Cooking with leftovers: the art of zero-waste cooking
This is where the magic happens. Many times, we waste food simply because we don’t know what to do with it. But with a little creativity, what would normally go in the trash can be transformed into delicious meals.
This concept is known as zero-waste cooking, a philosophy that aims to maximize the use of all available ingredients, minimizing waste and optimizing resources. Top chefs have embraced this mindset, proving that even the most overlooked parts of food can create gourmet dishes.
What is zero-waste cooking? It’s a way of preparing food where every part of an ingredient is used to avoid waste. For example, carrot peels can be used for broths, stale bread can become toast or pudding, and overripe fruit is perfect for smoothies, compotes, or homemade jams.
Did you know there's already a law promoting the sale of ugly fruits and vegetables to reduce food waste? Find out here how it works and why it's great news for the planet (and your wallet).
Another useful tip is learning to correctly interpret expiration dates. Many people confuse “best before” with “use by” dates. The first is merely a quality recommendation, while the second indicates a potential health risk. For products like yogurt or bread, the consumption window is often much longer than we assume.
It’s also a great idea to dedicate one day a week to batch cooking and freezing portions. If you cook in larger quantities, store individual servings for busy days. This reduces waste and saves you from the dreaded “What should we eat today?” dilemma.
4. Composting: the last resort for unavoidable waste
While our goal is to minimize waste, there will always be inevitable scraps, such as peels, apple cores, or coffee grounds. Instead of throwing them in the trash, we can give them a second life through composting.
Having a small compost bin at home doesn’t require much effort and is an excellent way to turn organic waste into fertilizer for plants. If you don’t have space for a compost bin, check for organic waste collection programs in your city or share your compost with neighbors who have urban gardens.
How can you compost at home? Gather organic waste like fruit and vegetable peels, coffee grounds, and eggshells in a compost bin. In a few weeks, they’ll turn into natural fertilizer for your plants.
