Kitchen Waste Reduction Guide
Waste isn’t just an ethical issue. It’s a GP issue. Every bin bag is money leaving the kitchen.
📈 Waste Is a GP Problem

Most kitchens lose 3–8% of revenue to avoidable waste. On a kitchen turning over €500k/year, that’s up to €40,000 walking out the back door. Waste reduction isn’t sustainability marketing. It’s protecting your margins.

🗑 Common Waste Areas
Prep & Production
✗Over-prepping — making more than service needs
✗Inconsistent portion sizes at the pass
✗Unused garnish trimmed but never plated
✗Mis-en-place not carried over efficiently
✗Complicated dishes with single-use components
Ordering & Storage
✗Over-ordering based on guesswork not sales data
✗Poor FIFO — new stock placed in front of old
✗Unlabelled containers — guessing dates
✗Menu duplication — same ingredient needed in 8 dishes, wasted in 3
✗No weekly dead stock review
Chef TipTrack your bin for one week. Photograph what goes in. Most kitchens are shocked by how much perfectly good food leaves because of over-prepping, not because it was actually bad.

Chef TipGreat chefs see a trim pile as raw material, not waste. The best staff meals come from the most creative use of what’s left over. Build a culture where finding a use for trim is a skill, not an afterthought.
⚖ Portion Control Reference
Product
Standard Portion
Chef Note
Protein (main)
160–200g
Weigh raw, consistent every time
Protein (starter)
80–100g
Precision matters — 20g over = €X lost per week
Fries (side)
120–140g
Use a portion scoop — every bag the same
Sauce (per plate)
40–60ml
Ladle or squeeze bottle — never free-pour
Salad leaves
40–50g
Pre-weigh portions at start of service
Butter (bread)
15g
Pre-portion quenelles — no guessing
Cheese (board)
30–40g per piece
Label the board with portion guide
Pasta (dried, main)
100–120g
Weigh dry — never eyeball
Chef TipA 20g overportioning on protein, across 80 covers per night, 5 nights per week = over 8kg of extra food cost per week. Standardise your portions. Every gram counts.
🗃 Cold Storage System
Labelling
▶Product name on every container
▶Date made AND use-by date
▶Allergen info where relevant
▶Who prepped it (accountability)
FIFO — Always
▶New stock goes to the back
▶Oldest stock always pulled first
▶Daily fridge walk — nothing forgotten
▶Dead stock list reviewed weekly
Organisation
▶Clear containers — see without opening
▶Raw and cooked always separated
▶Fridge map on the door
▶One person owns cold room integrity
👥 Building a Low-Waste Kitchen Culture

Waste reduction works best when the whole kitchen understands why it matters. When chefs understand that every kilo of trim wasted is money that could fund better equipment, better wages, or a longer season — they engage differently.

What Leaders Do
✓Show the team the food cost numbers — transparency builds ownership
✓Celebrate creative use of trim and surplus
✓Make the staff meal a pride moment, not an afterthought
✓Never shame waste — build systems instead
What to Brief the Team
▶Portion sizes and why they exist
▶How to label and rotate correctly
▶What to do when something is near its limit
▶Who to tell when something is wasted unexpectedly
Chef TipThe best kitchens treat waste as a system failure, not a personal failure. Build the prep sheet, the labelling system, and the fridge discipline so waste becomes structurally difficult, not just frowned upon.
