1. Create a weekly meal plan to reduce impulse buys at the checkout and ensure you use the food you purchase. 

2. Store food correctly to extend its shelf life. This includes refrigerating perishable items and using airtight containers. 

3. Freeze ingredients or leftover meals to prevent them from going to waste. 

4. Compost food scraps like vegetable peels, fruit rinds, and coffee grounds to create nutrient-rich soil. Composting is a great way to repurpose food waste. 

5. Donate excess, edible food to food banks, soup kitchens, or shelters. This helps reduce food insecurity and prevents food from going to waste.
