Increase Profitability. Reduce Your Losses by Reducing Food Waste – Here’s How

Food Waste is Growing – The Numbers Tell the Story

It is one of the biggest waste streams in Singapore. Food waste has grown by 20% in the past 10 years, with about 744 million kg of food was wasted in 2019 alone. That’s 2 bowls of rice per person per day. To put this into greater perspective, that’s about 51,000 double decker buses.¹

Food waste is a global problem that needs to be addressed, not only for environmental reasons, but also because of the economic implications it has on your restaurant and profitability.

Types of Waste and How to Reduce Them

Effective waste management can be summed up by the three R’s: Reduce, Reuse and Recycle. These three R’s are evident in several stages of the kitchen process. Below we’ve outlined three types of waste and have included tips to help you manage and reduce waste in each category.

Preparation Waste

Several things can be done to reduce waste during preparation:

Effective Purchasing:

• Try not over-order food: Only order the minimum amount required for a period to avoid unnecessary spoilage.
• Cook seasonal: Ingredients that are out of season have made a longer journey to your kitchen and have a higher risk of spoilage.
• Only buy bulk if it fits with your demand/are non-perishable.
• Consider frozen, dried, bottled or tinned goods as opposed to fresh where a comparable quality can be achieved.
• Perishable items should be used throughout the menu so that they are not wasted.

Production Planning – Reduce and Reuse

While most waste in restaurants are generated by the end product (cooked food that can't be donated or re-purposed), there are BOH (back-of-house) steps that help minimise waste. 

• During the production phase, waste occurs when ingredients are not prepared carefully (e.g., excess trimming of meat, vegetables, or fish) or ingredients that can actually be used are discarded (e.g., onion trimmings, carrots peels and parsley stems can enhance any soup or stock). As a result, a lot of costly waste can be reduced and reused during the production stage in most kitchens.
• Meat trimmings can be used for a pâté, a filling or in an appetizer format. You can even go are far as rendering the fats from the meat for other purposes.
• Cook smaller batches of pre-prepared staple food to make sure you don’t over order.
• Plan carefully. This optimizes your labour efficiency and reduces waste.
• Be flexible and reactive: tailor your mise en place to bookings, weather, holidays, etc, increasing and decreasing par levels accordingly.
• Avoid exceeding par stock levels and overdoing the mise en place, as often this leads to wasted stock and effort.

Spoilage Waste

How you store your ingredients plays a large role in reducing waste during storage. Use the ABC strategy to optimise the space of your storage:

• Category A: products that have a high turnover but relatively little pick locations.
• Category C: products that will be stored a lot longer than products in group A. They have a low turnover and take lots of space in the storeroom.
• Category B: products in between A and C according to turnover and pick frequencies.

When you use these categories to classify your products you can group your storage room and fridge into three zones. Zone A will always be closest to the door, then B, then C. Improved storage using this model can save you up to 60% of your time.

Portioning & Plate Waste

Smaller plate portions certainly make it easier to reduce waste, but they don’t always fit in with restaurant concepts. However, accurate portion control is key to reducing waste and increasing profitability so that over-portioned meals don’t end up in the garbage.

• Giving your guests control over how much they want to eat is a great way to start reducing waste. Consider offering dishes in different serving sizes and train staff to fully understand the benefits of the offer for both the business and the customer.
• See if you can offer second helpings on side dishes similar to the concept of bottomless soft drinks. This saves you from serving too much on the first pass, but still gives guests the feeling they’ve gotten their fill. Educating your FOH and BOH staff of the benefits — as well as the guests themselves — will be key in making this practice successful.
• A careful eye on sales tracking will help set production levels so you can be prepared for rushes and slow periods.
• Train staff to monitor plate waste to engage your staff in waste reduction efforts. This helps your team register what comes back from the restaurant as plate waste so that proper adjustments can be made to alter the portioning. This will also tell you which dishes may be underperforming so that you can make additional adjustments to your menu.
• Consider composting. Chef Einav Gefen is a seasoned culinary executive with UFS and says, “Compost is the best way to repurpose waste. It takes some behavior change but can be easily managed in house.” Many restaurants use dedicated garbage cans and compost cans back of house to create a simple compost system. She goes on to suggest reaching out to local environmental groups who often collect compostable items from restaurants.

With these tips and diligence in your kitchen, you can do your part to help reduce food waste to benefit the environment—and your bottom line. Plus when you get guests involved in the effort, you can go far in improving your brand’s equity. Look to startup companies and tech partners for support in your food waste reduction efforts. There are many powerful apps out there that can help along the way.
