Most restaurant teams struggle with waste reduction because they lack concrete targets to work toward. Without specific numbers, 'waste less' stays vague and unmeasurable. You need clear, achievable goals that translate abstract concepts into actionable targets.
Start by measuring your current waste
You can't improve what you don't measure. Track everything that gets thrown away for one full week and convert those amounts to money.
💡 Example:
Restaurant De Smaak measures for a week:
- Vegetables: 8 kg thrown away = €32
- Meat: 2 kg thrown away = €48
- Bread: 15 loaves = €22
- Other: €18
Total waste per week: €120
Per year: €120 × 52 = €6,240
Convert to a percentage of your purchases
Your team grasps percentages more easily than raw dollar amounts. Calculate what percentage of total purchases you're throwing away each week.
Formula: Waste % = (Amount thrown away / Total purchases) × 100
💡 Calculation:
Restaurant De Smaak:
- Waste per week: €120
- Total purchases per week: €1,500
- Waste percentage: (€120 / €1,500) × 100 = 8%
"Out of every €100 we purchase, we throw away €8."
Set an achievable goal
Don't jump from 8% waste to 2% overnight. That's a pattern we see repeatedly in restaurant financials - ambitious targets that backfire and discourage teams. Aim for gradual improvement of 1-2% monthly.
- Current waste 8%? Target 6% over 3 months
- At 6%? Move to 4% in the next 3 months
- Below 4% is excellent for most restaurants
⚠️ Note:
Zero waste isn't realistic. Expect 2-4% due to cutting loss, natural spoilage, and unavoidable waste.
Make it visual for your team
Post a progress board in the kitchen where everyone can see it. Update weekly so your team tracks how they're doing in real time.
💡 Example scoreboard:
WASTE REDUCTION GOAL MARCH
- Goal: From 8% to 6%
- Week 1: 7.5% ✅
- Week 2: 7.2% ✅
- Week 3: 6.8% ✅
- Week 4: ?
"We're already saving €18 per week!"
Link the goal to money that stays
Show your team what the savings actually means in dollars. People understand the importance better once they see how much money stays in the business.
- From 8% to 6% waste = 2% savings on purchases
- At €1,500 purchases per week = €30 per week savings
- Per year: €1,560 extra profit
- That's enough for a team outing or bonus
Discuss the goal in your team meeting
Spend 5 minutes in weekly meetings reviewing progress. Ask your team what they're noticing and where they spot opportunities for improvement.
✨ Pro tip from chef Marco:
"I discuss our waste from the previous week every Monday. The team now comes up with ideas to throw away less. They think along because they know the goal."
How do you set a concrete waste reduction goal? (step by step)
Measure your current waste for a week
Weigh everything you throw away and convert to money. Note by category: vegetables, meat, bread, dairy. Add up for total weekly amount.
Calculate your waste percentage
Divide your weekly waste by your total purchases and multiply by 100. This gives you the percentage that gets thrown away.
Set an achievable goal for 3 months
Reduce your current percentage by 1-2%. For example from 8% to 6%. Communicate this clearly to your team with a visual scoreboard.
✨ Pro tip
Track waste percentages for 2 weeks, then set a goal that's 1-2% lower than your current average. This creates momentum without overwhelming your team with unrealistic expectations.

Frequently asked questions
What is realistic waste for a restaurant?
Between 2% and 6% of your purchases is normal for most operations. Below 4% is excellent performance. Above 8% means you're losing significant money to preventable waste.
How often should I adjust the waste reduction goal?
Set new goals every 3 months. Your team needs time to adapt to each new level before moving lower. Rushing the process often backfires and creates frustration.
What if my team doesn't reach the goal?
Review what made it difficult and adjust if the target was too aggressive. An achievable goal that gets reached beats an unrealistic one that demotivates everyone.
Should I count cutting loss as waste?
No, cutting loss is normal and unavoidable in food prep. Focus your goals on preventable waste like spoilage, over-prepping, or misjudging demand patterns.
