Did you know?
If food waste were a country, it'd be the 3rd biggest greenhouse gas emitter — behind only the US and China.
Compost + preserve →Make it last longer.
Compost what won't.
Practical tricks — no fluff. Freeze it right, store it smart, revive what wilted, and give scraps a second life.
Food-by-food cheatsheet
- 🍌
Bananas
Compost: greenStoreSkin browns but flesh stays good 5-7 days.
FreezePeel, chunk, freeze on a tray — smoothies & banana bread forever.

Berries
Compost: greenStoreDon't wash until eating; store dry with a paper towel.
FreezeRinse, dry, freeze in a single layer, bag up.
- 🍞
Bread
Compost: greenStoreSkip the fridge — it stales bread faster.
FreezeSlice first, freeze in a bag. Toast straight from frozen.
ReviveStale? Sprinkle with water, bake 5 min at 350°F.
- 🥬
Leafy greens
Compost: greenStoreWrap in a dry paper towel, sealed bag, crisper drawer.
FreezeBlanch 30s, ice bath, dry, freeze for soups/smoothies.

FreezeWhole — skins slip off under warm water for sauce.
- 🥑
Avocado
Compost: greenStoreCut half: lemon juice + airtight container, 1-2 days.

FreezePortion flat in bags — reheats in 90 seconds.
- 🥛
Milk
Not backyardStoreBack of the fridge, not the door (temp swings).
FreezeYes — pour a splash out first, shake after thawing.
Dairy goes to municipal green bin, not backyard compost.
- 🧀
Cheese (hard)
Not backyardStoreWrap in wax/parchment, then loose plastic.
FreezeGrate first — great for cooking, texture changes.
- 🥚
Eggs
Compost: brownStoreIn the carton, middle shelf. Float test if unsure.
FreezeCrack, beat lightly, freeze in ice cube trays.
Shells only — crush first to speed breakdown.
- 🥩
Meat & fish
Not backyardStoreColdest shelf, use within 1-2 days.
FreezePortion, wrap tight, label with date. 3-6 months.
Never backyard compost — attracts pests.

FreezeIn their cooking liquid, flat in bags.
- 🍋
Citrus
Compost: greenStoreCrisper drawer, weeks longer than the counter.
FreezeZest first! Juice into ice cube trays.
Slow to break down — chop small.
- 🍎
Apples
Compost: greenStoreCrisper drawer, away from other produce.
FreezeSlice, toss in lemon juice, freeze for baking.
- 🍄
Mushrooms
Compost: greenStorePaper bag, never plastic — they need to breathe.
FreezeSauté first, then freeze. Raw gets slimy.
- 🥣
Yogurt
Not backyardStoreSealed, back of fridge. Trust smell over date.
FreezeFreezes fine for smoothies; texture breaks for eating.
Freezing 101
- 1
Cool it first
Warm food raises freezer temperature and re-thaws neighbors. Wait until room temp before bagging.
- 2
Flat, not lumpy
Freeze sauces, stock, and leftovers flat in zip bags. They stack, thaw in minutes, and free up shelf space.
- 3
Portion for real life
One person's dinner, not a family's. You're way more likely to actually use it.
- 4
Label everything
Date + contents in permanent marker. "Mystery brown 2024" is a compost destiny.
- 5
Blanch veg
Green beans, broccoli, greens: 30-60s boil, ice bath, dry, freeze. Kills the enzymes that turn them mushy.
Rough shelf life: cooked meals 2-3 months · raw meat 3-6 months · bread 3 months · fruit 6-12 months.
Store it right
- Fridge zones matter. Door = warmest (condiments only). Top = leftovers. Middle = dairy. Bottom = raw meat. Crispers = produce.
- Separate ethylene producers. Apples, bananas, tomatoes, avocados release ethylene gas and ripen neighbors fast. Keep them alone.
- Roots love the dark. Potatoes, onions, garlic, squash: cool dry cupboard, never the fridge.
- Herbs = flowers. Stems in water, loose bag on top, back in the fridge (except basil — leave it on the counter).
- Leftovers within 2 hours. Shallow containers cool faster and stay safer.
Revive, don't toss
- Wilted greens: 10 minutes in ice water. They stand right back up.
- Stale bread: Splash of water, 5 min at 350°F. Or blitz into breadcrumbs.
- Soft carrots/celery: Ice water bath, 30 min. Snappy again.
- Overripe fruit: Smoothies, jam, banana bread, roasted with pork.
- Sour milk (not spoiled): Pancakes, biscuits, marinades.
- Vegetable ends & scraps: Freezer bag → homemade stock when full.
Canning & quick pickles
Not ready for pressure canners? Start with refrigerator pickles — no special equipment, ready in 24 hours, keeps ~1 month.
Basic pickle brine
1 cup vinegar (white or apple cider) · 1 cup water · 1 tbsp salt · 1 tbsp sugar. Simmer, pour over veg in a jar, cool, fridge.
Works on: cucumbers, red onion, carrots, radishes, green beans, cauliflower.
For shelf-stable canning (water bath, pressure), follow tested recipes from your national food-safety authority — botulism is not a "wing it" situation.
Composting basics
Compost is a ratio game: greens (wet, nitrogen) + browns (dry, carbon). Aim roughly 1:2 greens to browns by volume.
✅ Greens (wet)
- Fruit & veg scraps
- Coffee grounds & filters
- Fresh grass clippings
- Plant trimmings
- Tea bags (no plastic)
🍂 Browns (dry)
- Dry leaves
- Cardboard (torn small)
- Newspaper
- Wood chips / sawdust
- Crushed egg shells
❌ Never (backyard)
Meat, fish, bones, dairy, oils, cooked food with sauces, pet waste, glossy paper. These attract pests and go rancid. Many cities' municipal green bins accept them — check your local program.
No yard? No problem.
- Countertop electric composters (Lomi, Mill) — 4-24 hrs, apartment-friendly.
- Bokashi bucket — ferments scraps under the sink, meat/dairy OK.
- Worm bin (vermicompost) — quiet, odorless, kids love it.
- Freezer stash + drop-off — bag scraps in the freezer, drop at a farmer's market or community garden.
Every skip of the trash counts.
A third of the food produced worldwide gets thrown away. You're not fixing that alone — but you're not nothing, either.
