LUNCHSCRAPS
Waste less, eat well — composting, food-waste and meal-prep guides, plus the kitchen tools to make it happen.

Zero-Waste Kitchen Tools & Calculators
Free tools for a lower-waste kitchen — compost calculator, food waste calculator, leftover recipe generator, kitchen inventory tracker, seasonal produce guide, and meal prep planner.
Compost Calculator
Balance your pile's carbon-to-nitrogen ratio — enter the greens and browns you're adding, each with a documented C:N constant, and see if your blend is in the ideal 25–30:1 range and how much to add to fix it
Food Waste Calculator
Turn your weekly food waste into annual weight, cost, and a CO₂e footprint using a documented emissions factor — then see the money, food, and emissions you'd save by cutting it
Leftover Recipe Generator
Tap the leftovers you have and get instant recipe ideas from a hand-curated rules table — fried rice, panzanella, banana bread, frittata, and more, with no AI and no network
Kitchen Inventory Tracker
Log pantry and fridge items with expiry dates and get a live use-first list sorted by date, flagging what's expiring within three days and anything already past it — saved privately in your browser
Seasonal Produce Guide
Pick a month and hemisphere to see which fruits and vegetables are naturally in season — shop fresher, cheaper, lower-carbon produce and plan meals around what's at its peak
Meal Prep Planner
Enter days, meals, and servings to get total portions, storage containers to prep, and a scaled shopping-quantity breakdown — so you batch-cook the right amount and waste less
Museum of Food & Sustainability
Wander an immersive museum of food and the planet that grows it — compost and the living soil alongside the harvest that feeds us, the age-old craft of preserving food, and the growing challenge of waste and the planet, each in its own gallery, so you can get to know the stories behind every scrap and every season: how each came to be, what makes it matter, and the role it plays in the way we eat and waste less today.
