How to reduce food waste in a restaurant kitchen

Every kilogram thrown away was paid for twice: once to buy it and once in the labour to store and prepare it. Most kitchens waste more than they think, and the first step to cutting it is seeing it.

Start by measuring

You cannot reduce what you do not record. For a few weeks, record every disposal with:

• the item and quantity, in its unit;
• the reason: expired, spoiled, overproduced, prep trim, returned plate, damaged in storage;
• where it happened.

Patterns appear quickly. Most waste usually comes from a handful of items and one or two reasons.

Receive carefully

Waste often arrives with the delivery. Check quality, weight and expiry when goods arrive, and reject what is not right. Record rejected goods separately so they never enter usable stock and the supplier is credited.

Store for first expiry, first out

Put new stock behind old stock, and label containers with the date received or prepared. For items with printed expiry dates, use the one that expires first, not the one that arrived first. Check the chiller temperature: spoiled stock is waste that started with storage.

Plan prep from demand

Overproduction is the most common avoidable waste. Plan prep from expected covers, and from what was actually sold on similar days, rather than habit. Prepare in smaller batches through service where the menu allows.

Set par levels

A par level is how much of an item you want on hand. Order and prepare up to it, not beyond. Review pars when the menu or the season changes, because pars set for a busy month waste in a quiet one.

Standardise portions and recipes

Write recipes with exact quantities and expected yield, and train the team on them. Compare actual yield with expected for your highest-cost dishes. A small over-portion repeated hundreds of times a week is real money.

Use trim and surplus well

Plan specials and staff meals around trim and surplus that is still good. Done well, it turns would-be waste into sales.

Watch expiry before it happens

Look at what expires in the next few days, every day, and use it first or move it to an outlet that will. Expired stock should be blocked from use and disposed of with a record, never left on the shelf.

Make it everyone’s job

Share the waste figures with the kitchen team each week, by reason. People fix what they can see.

How Buddhi helps

Buddhi records disposals with reasons and values, flags batches that are about to expire and blocks expired ones from use. Production orders compare actual yield with recipes, goods receipts record rejections separately, and the waste and expiry report shows where waste comes from by item, outlet and reason. ChainGuard highlights unusually high waste for an owner to look at.
