Are You Literally Throwing Money in Your Kitchen Trash?
We all know that feeling – staring into the refrigerator at slightly wilted vegetables, wondering if they’re still good, then reluctantly tossing them in the trash. Or automatically discarding those onion ends, carrot peels, and herb stems as you prep dinner.
But what if I told you that the average family throws away over $1,500 worth of food annually? And beyond that, many of the kitchen items we routinely discard could be repurposed, saving us from buying new products and putting serious money back in our pockets.
After tracking my own kitchen waste for a month, I was shocked to calculate the potential savings. By implementing these 10 simple zero waste kitchen practices, you could save well over $1,000 this year – while helping the planet too!
Let’s dive into the top 10 kitchen items you should stop throwing away immediately:
1. Vegetable Scraps → Homemade Stock
What most people toss: Onion ends, carrot peels, celery leaves, mushroom stems, leek tops, and other vegetable trimmings
The zero waste solution: Keep a “stock bag” in your freezer. Every time you prep vegetables, add the clean scraps to this bag. Once full, simmer the contents with water and herbs for 1-2 hours to create a flavorful vegetable stock that’s far superior to store-bought versions.
Annual savings: Store-bought organic stock costs $5-7 per quart. Making your own once weekly adds up to $260-364 saved annually.
Pro tip: Add a tablespoon of apple cider vinegar to help extract more nutrients from the vegetable scraps.
2. Coffee Grounds → Garden Gold
What most people toss: Used coffee grounds – Americans discard millions of pounds daily!
The zero waste solution: Coffee grounds are nitrogen-rich garden fertilizer for acid-loving plants. Simply sprinkle them around plants or add to compost. Alternatively, mix with coconut oil and sugar for a natural exfoliating body scrub.
Annual savings: Commercial organic fertilizer ($15/month) plus store-bought coffee scrubs ($20/month) equals $420 annual savings.
Pro tip: Coffee grounds also deter slugs and snails from garden beds – a natural pest control solution!
3. Glass Jars → Free Storage System
What most people toss: Pasta sauce, pickle, jam, and condiment jars
The zero waste solution: Remove labels (soak in hot water), thoroughly clean, and repurpose as food storage, pantry organization, or to-go containers. They’re perfect for storing homemade sauces, dried goods, leftovers, and even packed lunches.
Annual savings: Quality glass food storage containers cost $5-15 each. Repurposing just 30 jars annually saves $150-450.
Pro tip: Keep various sizes for different purposes – smaller jars work perfectly for homemade salad dressings and spice mixes.
4. Stale Bread → Gourmet Ingredients
What most people toss: Bread ends, stale slices, or slightly hardened loaves
The zero waste solution: Transform them into breadcrumbs, croutons, bread pudding, or French toast. For breadcrumbs, simply toast the bread until completely dry, then pulse in a food processor. Store in a repurposed jar for up to three months.
Annual savings: Artisanal breadcrumbs cost about $4 per container. Making your own twice monthly saves approximately $96 annually.
Pro tip: Season homemade croutons with olive oil, garlic powder, and herbs before baking for gourmet salad toppers that taste better than anything store-bought.
5. Citrus Peels → Natural Cleaning Products
What most people toss: Lemon, lime, orange, and grapefruit rinds
The zero waste solution: Place citrus peels in a jar, cover with white vinegar, and let sit for 2 weeks. Strain and dilute with equal parts water for an effective all-purpose cleaner that smells amazing and contains no harsh chemicals.
Annual savings: Natural cleaning products average $5 per bottle. Making your own monthly saves about $60 annually.
Pro tip: Orange peels work especially well for removing greasy residue from kitchen surfaces and appliances.
6. Herb Stems → Instant Flavor Boosters
What most people toss: Woody stems from herbs like rosemary, thyme, basil, and parsley
The zero waste solution: Chop herb stems finely and freeze in ice cube trays with olive oil or butter. Pop out a cube whenever you need instant flavor for cooking. Alternatively, add woody stems directly to soups and stews while cooking (remove before serving).
Annual savings: Herb-infused oils cost about $4 each. Creating your own monthly saves approximately $48 annually.
Pro tip: Different herb stems have different uses – woody rosemary and thyme stems flavor stocks beautifully, while tender cilantro and parsley stems can be used anywhere you’d use the leaves.
7. Bones → Nutritious Bone Broth
What most people toss: Chicken carcasses, beef, pork, or fish bones
The zero waste solution: Save bones from meals in a freezer bag. When you have enough, roast them for extra flavor, then simmer for 12-24 hours with a splash of apple cider vinegar (which helps extract nutrients). The resulting bone broth is incredibly nutritious and versatile.
Annual savings: Quality bone broth costs about $8 per quart. Making your own twice monthly saves approximately $192 annually.
Pro tip: Add vegetable scraps from your stock bag for additional flavor complexity.
8. Wilted Greens → Smoothie Starters
What most people toss: Slightly wilted spinach, kale, lettuce, or other leafy greens
The zero waste solution: Slightly wilted (but not spoiled) greens are perfect for green smoothies. Wash, chop, and freeze them in portions. Add directly to your blender from frozen – they create a perfectly chilled smoothie with no ice needed.
Annual savings: Organic greens cost about $3.50 per bag. Saving one bag weekly from the trash equals $182 annually.
Pro tip: Add a squeeze of lemon juice before freezing to help preserve color and nutrients.
9. Leftover Wine → Homemade Vinegar
What most people toss: Unfinished wine that’s been open for a few days
The zero waste solution: Instead of pouring it down the drain, use leftover wine to make your own vinegar. Simply leave it in a jar covered with a cloth (to keep out insects but allow airflow) for 1-2 months. The natural fermentation process will transform it into delicious homemade vinegar.
Annual savings: Artisanal wine vinegar costs about $4 per bottle. Making 15 bottles yourself annually saves approximately $60.
Pro tip: Add a splash of existing vinegar with “mother” (like raw apple cider vinegar) to speed up the fermentation process.
10. Food Packaging → Seed Starters
What most people toss: Egg cartons, toilet paper rolls, yogurt containers, and other packaging
The zero waste solution: Repurpose these items as biodegradable seed starters for your herb and vegetable garden. Egg cartons and toilet paper rolls can be planted directly into soil as they decompose naturally.
Annual savings: Herb plants cost $3-4 each at nurseries. Growing 30 plants from seeds saves $90-120 annually.
Pro tip: Label your seedlings with plant markers made from old popsicle sticks or cut-up plastic containers.
The Numbers Don’t Lie: Serious Savings Add Up
Let’s tally up the potential savings from these simple changes:
- Vegetable Stock: $364/year
- Coffee Grounds: $420/year
- Glass Jars: $150/year (conservative estimate)
- Breadcrumbs/Croutons: $96/year
- Cleaning Products: $60/year
- Herb Cubes: $48/year
- Bone Broth: $192/year
