Strategies for Achieving a Zero-Waste Kitchen in Your Restaurant

The restaurant industry has been undergoing some significant changes of late. One of the most prominent is its engagement in the zero-waste movement. Leaders in the sector have noted not just the potential to attract customers who are increasingly making purchasing decisions based on their environmental ethics. It’s also a more fiscally responsible approach to business, reducing overheads caused by unnecessary resource consumption.

Is zero waste achievable? It is, but it’s also important to recognize that reducing unnecessary consumption is a process. You’re unlikely to eliminate all your sources of overuse immediately. It takes commitment alongside some investment in specific areas of operations. So, let’s look a little closer at the concept. What strategic steps can you take to bring your kitchen closer to achieving zero-waste?

Managing Inventory

The first area of focus for any waste elimination strategy is your restaurant’s approach to ingredients. This is one of the most significant areas of inefficiency for any food business. A recent study — Food Waste on Food Service — reported that, on a global scale, around $2.6 trillion dollars is lost due to wasted food. By managing your food more effectively, you’re minimizing costs and reducing pressure on the environment.

An excellent place to start is optimizing your shelf life management to ensure food lasts as long as possible. Automated inventory controls are becoming more accessible to even small restaurants, so implementing these throughout your organization is worth implementing. For instance, smart temperature controls independently adjust heating and cooling to maintain optimum conditions for ingredients, preventing spoilage. Using inventory management software, too, can give you visibility of the items transitioning through your storage, helping you practice good first-in, first-out (FIFO) practices. Not to mention that the data these systems gather enables you to produce accurate forecasting so you don’t unnecessarily overorder.

Even with the best inventory management in the world, there may be times when customers don’t want to eat all of the food you provide them. When aiming for zero waste, it’s a fundamental responsibility to handle leftovers effectively. When designing your dishes, establish realistic portion control for each meal. Err on the side of caution here, as you can constantly adjust upwards if you get feedback from customers that they didn’t receive enough food.

Training Staff

It does no good to look at waste reduction strategies for your restaurant’s operations if your staff doesn’t have a similar commitment to the concept. You need to ensure that your employees have the mindset and the skills to cooperate in making your company a more environmentally friendly and ethical space. Therefore, training in waste reduction is essential.

Some of the focuses for training staff could include:

• Prep efficiency: The food prep process tends to be a common point for producing too much waste. Training your kitchen staff in techniques that avoid over-prepping is essential, as this minimizes uneaten food at the end of the service. Ensure they know how to review demand forecasts and make informed decisions about the likely volumes of each dish needed for each service. 

• Ingredient maximization: Kitchens often only use a part of the ingredient before throwing the whole thing away. Processes should be improved to ensure every ingredient is used fully. For example, bones and unused vegetables are perfect for broth. Ensure cooks know how to use every part of the animal.

• Monitoring practices: It’s difficult to reduce food waste if you don’t know what is being wasted. Therefore, train your staff in waste monitoring practices. Teach workers how to implement a waste auditing system that allows both you and them to identify patterns in wastage. Apps and other software can help with tracking, but encouraging staff to be eagle-eyed and mindful of areas for improvement is even more helpful.

Remember that simply training your staff on the skills they need to reduce waste isn’t enough. You also need to teach them why these efforts are so important. Help them understand how these steps align with your ethical and environmental values. Highlight how lowering costs through zero waste makes the restaurant more profitable, which affects staff salaries. Giving them knowledge enables them to make independent decisions on their engagement level with your strategies.

Utilizing Resources Efficiently

Food waste is far from the only area where your restaurant can improve its environmental friendliness. Sustainability is measured by looking at a number of areas throughout a business. Alongside other forms of waste production, energy consumption and water usage help give a more comprehensive view of a business’s carbon footprint. By establishing ways to use your resources more efficiently, you get closer to achieving a more holistic form of zero-waste in your kitchen.

Some of the areas worth considering include the following.

Energy-efficient equipment

When you look at your electricity bills, a large proportion of those kilowatts per hour are likely to be used by your kitchen equipment. Ovens and refrigerators, in particular, are energy-hungry devices. Therefore, one of your priorities should be to invest in energy-efficient equipment. Wherever possible, opt for items that are Energy Star-rated. This government-backed program makes it easier for consumers to identify appliances that meet high energy-efficiency standards. It’s also worth considering that electric stoves use less energy than their gas counterparts, so minimizing gas use where possible is critical to eliminating wasted energy.

Another step toward zero waste as far as energy is concerned is to maintain your equipment. Even an Energy Star appliance may reduce performance over time. Therefore, regularly having your appliances inspected to ensure they run efficiently helps you to keep energy use to a minimum.

Water conservation practices

Your kitchen likely uses water in a range of areas. Cooking, cleaning, bar service, and bathrooms, among others, are vital points that water will be used by staff and customers alike. Always ensure you’re not using a greater volume than is absolutely necessary, particularly if you’re operating in a hot climate where droughts are common. 

Installing low-flow faucets and aerators can be effective, as these reduce the volume of water being used without significantly impacting functionality. However, it is staff behavior that most affect water conservation. Make sure your kitchen staff understands the situations in which water can be reused. For instance, in many cases, the water used for rinsing vegetables can then have a second life in producing stock. 

Again, maintenance is a key to water conservation. Even minor deterioration in your plumbing can lead to performance issues and leaks that mean you’re using more water than necessary. Regular inspections and ensuring that any problems with water pressure are immediately addressed can help you keep your water use down.

A zero-waste restaurant is certainly achievable, but it may require a shift in mindset and some investment in a range of areas. The rewards are certainly well worth the effort. By focusing on solid inventory management practices, staff training, and minimizing resource consumption, you can start to make a real difference. You don’t have to do everything all at once, though. Remember that there’s a journey to zero waste and that taking careful steps along the path can help make your efforts more substantial and sustainable.
