Sustainability is the buzzword of the moment. But how sustainable is your car wash really? And more importantly: how can you ensure that your business doesn’t just appear greener, but actually becomes more sustainable? Sustainability is no longer just a trend—it’s a hard requirement. Companies must comply with the CO2 agreement guidelines by 2030. Environmental requirements are also playing an increasingly important role when applying for a new permit. For car wash entrepreneurs, this means that becoming more sustainable isn’t optional—it’s essential to remain competitive and future-proof.
Water usage: are you really saving as much as you think?
Water is one of the most important consumption factors in the car wash industry. Many entrepreneurs claim their installation saves water, but how many liters are actually used per wash?
Facts and figures:
- A traditional car wash without water recycling consumes an average of 150 to 200 liters of water per wash.
- Modern water recycling systems can reuse up to 85% of this water, reducing consumption per wash to just 20 to 30 liters.
- An average household in the Netherlands uses about 120 liters of water per day. A non-sustainable car wash can use more than a family does in one day!
What can you do?
- Use a water recycling system and measure what percentage is actually reused.
- Work with osmosis water or other techniques that reduce waste.
- Monitor your water usage per wash and compare it with the market standard.
Energy consumption: green energy or power guzzler?
A car wash consumes quite a lot of energy—from washing installations to dryers and lighting. But where does that energy come from?
Facts and figures:
- Replacing conventional lighting with LED lighting saves up to 70% in energy and can save hundreds of euros annually on your electricity bill.
- A car wash without sustainable energy solutions can consume up to 50,000 kWh annually, comparable to 15 households.
- Installing solar panels can allow a car wash to generate up to 30% of its electricity independently.
What can you do?
- Use solar panels to generate (part of) your energy independently.
- Use LED lighting instead of conventional lighting.
- Choose an energy-efficient heating system.
As a car wash investor, if you invest in LED lighting, you can significantly reduce your energy costs. You can then use those savings to invest in a water recycling system, making your business more sustainable in both energy and water.
Cleaning agents: truly biodegradable or just a fancy label?
Many car washes advertise biodegradable shampoos and waxes, but are these products truly environmentally friendly? Take a close look at certifications and quality marks.
What to look out for:
- Are the products free of microplastics?
- Do they carry the EU Ecolabel or another recognized environmental mark?
- Are they free of harmful solvents and phosphates?
What can you do?
Choose cleaning agents that are not only biodegradable but also work effectively at lower temperatures. This saves both water and energy.
Waste management: from waste to reuse
Every car wash produces waste—from sludge to packaging of cleaning products.
How do you deal with this?
- Do you have a well-functioning sludge separation system?
- Do you use recycled packaging or refillable containers?
- Do you sort your waste correctly and limit unnecessary plastic use?
Facts and figures:
- An average car wash produces more than 500 kg of sludge waste annually.
- Using recycled packaging can reduce plastic waste by up to 40%.
Tip: consider partnering with sustainable suppliers that support recycling and reuse.
Common mistakes when going green
When making a car wash more sustainable, mistakes are often made that reduce the effectiveness of sustainable investments.
Common pitfalls:
- Using ‘green’ shampoos without certification: Many car washes claim to use eco-friendly shampoos, but without recognized certifications, this is hard to verify.
- Installing solar panels without energy-efficient machines: If your machines still consume a lot of energy, the impact of solar panels remains limited.
- Insufficient monitoring: Without data on water and energy use, it’s hard to identify where real savings can be made.
- No transparency toward customers: Sustainability only works if customers know what efforts are being made.
Sustainability as a business model
Truly sustainable entrepreneurship is not only good for the environment, but also for your revenue. More and more customers are consciously choosing a sustainable car wash.
The popularity of car washes is increasing, while the number of people washing their cars at home is declining (BOVAG). This suggests a growing preference for professional car washes—likely due to efficiency and eco-friendliness. Additionally, research by Nationale-Nederlanden shows that nearly half of private car owners want to opt for a more sustainable vehicle next time, with environmental considerations as the main reason.
Although this research focuses on vehicle purchases, it reflects a broader trend where consumers are placing increasing importance on sustainability in their choices. By tapping into this, car washes can build a positive brand image and increase customer loyalty.
This is how you turn sustainability into a marketing tool:
- Communicate your water and energy savings to your customers.
- Offer loyalty programs for conscious customers.
- Provide discounts or extras for electric vehicles or customers who choose the most environmentally friendly wash programs.
Take action and make your car wash truly sustainable
Sustainability is no longer an option—it’s a necessity. Regulations are getting stricter, and customers expect transparency. Don’t wait until it’s too late. Start making your car wash more sustainable today.
