Reducing food waste by just 20% saves most restaurants €3,000-8,000 annually in combined ingredient and disposal costs. Food waste hits your bottom line twice: you pay for ingredients that get tossed, then pay again to have that waste hauled away. Here's how to calculate both costs so you know exactly what waste is costing your operation.
What are waste disposal costs?
Waste disposal costs break down into collection fees and processing charges. Restaurants typically deal with organic waste (produce scraps, food prep waste) and general waste that can't be composted.
- Organic waste: €80-120 per ton
- General waste: €150-250 per ton
- Collection costs: €15-30 per pickup (varies by container size and frequency)
💡 Example:
A restaurant serving 100 covers daily discards roughly 15 kg of food per day:
- Annual waste: 15 kg × 365 days = 5,475 kg
- Organic processing: 5.5 tons × €100 = €550
- Weekly collections: 52 weeks × €25 = €1,300
Total annual disposal costs: €1,850
Calculate your real waste costs
Your true waste expense equals ingredient cost + disposal fees. Most operators only track the ingredient cost, which gives you an incomplete picture of what waste actually costs.
💡 Real-world calculation:
Daily vegetable waste worth €20 at purchase price:
- Annual ingredient loss: €20 × 365 = €7,300
- Waste weight: approximately 8 kg vegetables
- Daily disposal cost: 8 kg × €0.10/kg = €0.80
- Annual disposal cost: €0.80 × 365 = €292
True waste cost: €7,300 + €292 = €7,592
How high are waste costs per kilo?
For quick calculations, these per-kilo rates work well:
- Organic waste: €0.08 - €0.12 per kilo
- General waste: €0.15 - €0.25 per kilo
- Mixed kitchen waste: €0.10 - €0.15 per kilo
⚠️ Note:
Rates differ by location and waste company. Check your actual invoices for precise costs. Some areas charge per pickup, others by weight.
Different types of food waste
Disposal costs vary depending on what type of waste you're throwing out:
- Prep waste: peels, bones, trimmings → typically organic waste
- Spoilage: expired ingredients → organic or general waste
- Overproduction: excess prepared food → usually general waste (contains oils, seasonings)
- Plate waste: customer leftovers → always general waste
💡 Cost comparison:
Same 10 kg of daily waste, different disposal costs:
- Pure prep scraps (organic): €1.00 daily
- Prepared dishes (general): €2.00 daily
- Mixed waste: €1.50 daily
Annual difference: €365 - €730
Reducing waste pays off twice
From years of working in professional kitchens, I've seen how every kilo of prevented waste saves both ingredient costs and disposal fees. The savings multiply with premium ingredients.
- Meat/fish: €15-30/kg purchase + €0.15/kg disposal
- Vegetables: €2-5/kg purchase + €0.10/kg disposal
- Dairy: €3-8/kg purchase + €0.15/kg disposal
Tracking waste with tools like KitchenNmbrs shows exactly where you'll save the most. You can log waste by ingredient or dish to see what's costing you the most money.
How do you calculate waste disposal costs? (step by step)
Check your waste invoice
Look at your waste processor's invoice for the rate per kilo or per pickup. Also note how often your container is emptied per week.
Weigh your food waste
Track for a week how many kilos of food you throw away per day. Estimate the share of organic waste (peels, raw vegetables) versus general waste (cooked leftovers).
Calculate the real costs
Multiply the weight by your waste rate per kilo. Add this to the purchase value of discarded food for the total waste costs.
✨ Pro tip
Track all food waste for exactly 14 days, recording both weight and purchase value. Multiply by 26 for your annual waste cost - most operators are stunned by this number.

Frequently asked questions
Should I include waste costs in my food cost calculation?
No, waste costs are a separate expense category. Food cost only includes ingredient purchase price divided by menu price. Waste disposal belongs in your operational expenses.
What if my municipality charges per pickup instead of per kilo?
Divide your total waste costs by total weight discarded. Example: €30 per pickup with 150 kg waste = €0.20 per kilo disposal cost.
Are there ways to lower waste costs?
Yes - reduce pickup frequency, separate waste types (organic costs less), or compost on-site. But the biggest savings come from wasting less food in the first place.
How much do restaurants waste on average?
Most restaurants waste 5-15% of purchased ingredients, roughly 10-30 kg daily for typical operations. Disposal costs alone run €300-1000 annually before counting ingredient losses.
