Sustainability is no longer a trend, but a fundamental expectation of modern guests.
More and more consumers consciously choose restaurants that operate in an environmentally friendly way. Fortunately, green choices often go hand in hand with cost savings. In this in-depth article, we share 5 practical, immediately applicable strategies to make your restaurant more sustainable, without it coming at the expense of your bottom line.
Why sustainability pays off for your restaurant
Beyond the ethical motivation of contributing to a better world, there are plenty of business reasons to go green. Sustainability is not only good for the planet, but also for your wallet and your competitive position.
- Lower energy and water bills: By using energy and water more efficiently, you can save thousands of euros a year on your fixed costs.
- Less food waste means lower costs: Every kilo of food you throw away is money thrown away. By reducing waste, you directly improve your margin.
- Appealing to eco-conscious guests: Research shows that more than 60% of consumers are willing to pay more at sustainable restaurants.
- Positive for your brand image: A green image sets you apart from competitors and builds customer loyalty.
- Prepared for stricter regulations: Governments are imposing ever stricter requirements on businesses. By going green now, you stay ahead.
- A motivated team: Employees like working for a business with a mission and sustainable values.
An important first step is to map out your current situation. How much energy do you use? How much food do you throw away? By measuring these figures, you can make targeted improvements and track your progress.
Strategy 1: Tackling food waste: the biggest win
The hospitality sector throws away tonnes of food every year. In the Netherlands alone, it amounts to hundreds of millions of kilos of food waste per year. This is not only bad for the environment, but also a huge cost. Fortunately, there are many ways to combat food waste.
1. Better forecasting with data and analytics
Use analytics and your reservation system to accurately predict how many guests to expect on which days and times. With this information, you can purchase and prepare far more precisely.
Analyze historical data to recognize patterns: which days are busy, which dishes are popular per season, and how does the weather affect your visitor numbers? By using this information, you avoid both shortages and surpluses.
A smart reservation system gives you real-time insight into expected covers, so your kitchen can prepare exactly what's needed. This saves not only food, but also labour costs.
2. Smaller portions with a top-up option
Offer slightly smaller portions as standard, with the option to order more. Many guests appreciate this because they can eat exactly as much as they want, without feeling guilty about leftover food. This also contributes to lower food costs.
Consider introducing a half-portion system for certain dishes. This is especially popular for starters and desserts. You can also offer tapas-style dishes where guests can share several small portions.
Communicate this positively to your guests: emphasize the chance to taste more rather than focusing on smaller portions.
3. Partnering with Too Good To Go and takeaway options
Sell surpluses through apps like Too Good To Go or offer them to staff at reduced prices. These apps have millions of users and help you recoup value from unsold food instead of throwing it away.
You can also set up your own system for late pickup of surpluses. Many restaurants offer remaining meals at the end of the evening for a reduced price, which can also attract new customers.
Don't forget that your staff are also a good destination for surpluses. A free meal for employees boosts satisfaction and prevents waste.
4. Nose-to-tail and root-to-stem cooking
Use the whole animal or the whole vegetable. This is a philosophy that's becoming increasingly popular with top chefs and helps you extract maximum value from your ingredients.
Make stock from carcasses, vegetable trimmings and peels. This stock forms the basis for soups, sauces and risottos. Use the leafy greens of carrots and beetroot in salads or pestos. Turn overripe fruit into smoothies, desserts or compotes.
Train your kitchen staff in these techniques and encourage creativity. Often the tastiest dishes emerge from the challenge of making something new out of what would otherwise be thrown away.
5. FIFO system and inventory management
Implement the First In, First Out (FIFO) principle consistently in your storerooms and fridges. This means older products are placed at the front and used first. Label all products with a date and keep things clearly organized.
Carry out regular stock checks and adjust your orders based on what you actually use. A good inventory management system can help you know exactly what you have and what you need.
Strategy 2: Saving energy and water: direct cost reduction
Energy costs make up a significant part of a restaurant's operating costs. By managing energy and water smartly, you can not only shrink your ecological footprint, but also cut your bills considerably.

LED lighting: a quick payback
Replace all bulbs with LED lighting. LED bulbs use up to 80% less energy than traditional incandescent bulbs and last many times longer. You usually recoup the investment within one to two years.
Modern LED lighting is available in every colour and warmth, so the atmosphere needn't suffer. You can even install dimmable LEDs to adjust the ambiance to the time of day.
Don't forget the outdoor lighting and motion sensors either. In spaces that aren't used continuously, such as toilets and storage rooms, sensors can save a lot of energy.
Choosing energy-efficient equipment
When replacing equipment: always choose models with the highest energy rating. A+++ equipment uses considerably less energy than older models. Also look into induction cooking - this method is more efficient, cooler in the kitchen, and safer than gas.
Also consider purchasing an energy management system that monitors your consumption and flags peaks. Many energy suppliers offer these systems along with advice on optimization.
Maintain your equipment regularly. A well-maintained fridge or oven works more efficiently and lasts longer. Schedule periodic checks and cleanings.
Water-saving measures
Install water savers on all taps. These simple adjustments can reduce your water consumption by 30-50% without you noticing anything in use.
In the kitchen, sensor taps make a big difference. The water only runs when you hold your hands underneath, which prevents waste during cooking and washing up.
Also consider a water-recycling system for your dishwasher, and think about collecting and reusing rainwater for cleaning purposes or watering plants.
Smart heating and cooling
Program your thermostat so the heating or air conditioning only runs when needed. At night and on closing days the temperature can be turned down, and you can have the heating start up automatically before you open.
Check the insulation of your premises and seal up gaps and cracks. Close doors between the kitchen and dining room to prevent heat from cooking overheating the room, which causes extra air-conditioning costs.
Consider heat recovery from your ventilation or cooling system. The heat you extract can be used to pre-warm the fresh air coming in.
Strategy 3: Sustainable purchasing: quality over quantity
What you buy largely determines the sustainability of your restaurant. By making conscious choices about your suppliers and products, you make a big difference.
Buying local and seasonal
Choose local suppliers and seasonal products. This means less transport and therefore lower CO2 emissions. What's more, seasonal products are fresher, taste better, and are often cheaper because of the larger supply.
Build relationships with local farmers, bakers and producers. You can even go a step further by mentioning their names on your menu, which adds authenticity to your concept.
Consider a vegetable garden or herb garden at your restaurant. Fresh herbs from your own garden give your dishes a unique flavour and reduce your purchasing costs.
Less meat, better quality
Consider more plant-based options on your menu. Meat production has a large ecological footprint, and more and more guests are looking for vegetarian or vegan alternatives.
If you serve meat, choose quality over quantity. Organic meat from local farmers is more sustainable and tastes better. You can charge higher prices for better quality, and many guests appreciate this.
Experiment with plant-based proteins as the main ingredient rather than a side dish. There are many innovative plant-based products available these days that even appeal to meat-eaters.
Going packaging-free where possible
Work with suppliers who use returnable packaging or deliver in bulk. Many greengrocers and bakers are willing to deliver in reusable crates if you ask.
Avoid single-use plastics as much as possible. Choose paper straws, wooden stirrers, and reusable containers for takeaway. Since 2024, many single-use plastics have been banned, so you're prepared by using alternatives now.
Strategy 4: Communicate your sustainability efforts
Be open about your sustainability steps, but avoid greenwashing. Guests value honesty and authenticity more than exaggerated claims.
- Tell people on your website what you do and why. Create a dedicated page about your sustainability initiatives.
- State the origin of products on the menu. Guests find it interesting to know where their food comes from.
- Train staff to answer guests' questions. They are your ambassadors and must be able to tell your story.
- Share updates and successes via social media. Show what you're doing with photos and stories.
- Consider certification such as Green Key to have your efforts officially recognized.
Also ask your guests for feedback on your sustainability initiatives. They may have valuable suggestions and feel involved in your mission.
Strategy 5: Start small and build up
You don't have to do everything at once. Going green is a journey, not a destination. Start with the measures that deliver the most - namely tackling food waste and saving energy - and build from there.
Set concrete goals and measure your progress. For example: reduce food waste by 20% within six months, or replace all lighting with LED within a year. By setting measurable goals, you stay motivated and can celebrate successes.
Involve your team in the sustainability process. Ask for ideas and make someone responsible for tracking progress. When your whole team is behind the mission, you achieve results faster.
Conclusion: sustainability as a strategic advantage
Running a sustainable business in hospitality isn't a sacrifice - it's smart business. By reducing waste and working more efficiently, you improve your profit margin while contributing to a better world.
The benefits are numerous: lower costs, a stronger brand image, more loyal guests, a more motivated team, and a head start on stricter regulations. More and more consumers make conscious choices and opt for restaurants that share their values.
Start today with small steps. Measure your current situation, choose one or two areas to improve first, and build from there. Your guests appreciate it, your team appreciates it, your wallet appreciates it, and so does the planet. Sustainability isn't the future of hospitality - it's the present.
