On behalf of the Dutch Consumers' Association, in 2005 the Pré research bureau compared tap water and bottled water with regard to greenhouse gases.

Water type
Greenhouse gas emissions (grams of CO2/litre of water)
Tap water
0,34
Spring water (in multi-use plastic bottle)
12 (factor 35 compared to tap water)
Spring water (in beverage cartons)
42 (factor 124 compared to tap water)
Spring water (in plastic bottle)
170 (factor 500 compared to tap water)

Every year, 2.5% of global oil production is used for the production of 2.7 million tonnes of plastic bottles. In the United States alone, the total amount of oil needed to do this is equivalent to refuelling 1 million cars.

Huge mountain of waste

Bottle water also contributes to the enormous waste mountain. In Belgium, we use 1.2 billion PET bottles every year. In the United States, 1,500 plastic bottles end up in the trash every second. And yet, throughout the world, only 20% of PET bottles are recycled.

The other bottles end up in incinerators, which again generates extra CO2 emissions, or end up in the sea. According to marine biologist Richard Thompson of the International Marine Litter Research Unit, the number of plastic bottles that end up in the oceans is so high that chemical traces, 'microplastics', are almost always found in seawater samples. The plastic soup in the Pacific Ocean, also known as the 'Great Pacific Garbage Patch', continues to grow: the island of plastic is now 60 times bigger than Belgium.

A short calculation

Imagine: you buy an AQUALEX tap water cooler or a multifunctional design tap. How do you contribute to the environment? Well, an average family causes 43 kilograms of CO2 emissions every year through its total tap water consumption. For bottled water this is 300 times as much. Per sold tap water cooler.

This is how AQUALEX reduces CO2 emissions by more than 12,000 kilos per year per family.

Let's also calculate how many trucks we remove from our roads. An average Belgian consumes 130 litres of bottled water every year. If you completely switch to tap water at home, that means that (for a family of 4) you consume 520 litres of tap water per year instead of bottled water. Assuming a lifespan of 10 years per AQUALEX device, this means that you use 5,200 litres of tap water. One pallet holds 672 bottles (14 rows on 4 layers on 12 bottles). 672 bottles of one and a half litres are good for 1,008 litres per pallet. A fully loaded truck contains 26 block pallets. This results in a total of 26,208 litres of bottled water per truck. So, for every 5 devices it sells, AQUALEX takes one truck off the road! And assuming an office environment where 20 people drink tap water (good for 2,600 litres per device per year), one sold device is enough to have one less truck on our roads.

Number of plastic bottles saved annually per device sold (at home)

An average Belgian consumes 130 litres of bottled water each year. If you completely switch to tap water at home, this means that (for a family of 4) you consume 520 litres of tap water per year instead of bottled water. That is the equivalent of 347 bottles.

Calculation

130 litres per year * 4 persons = 520 litres per device in a house per year / 1.5 litres

Number of kilograms of CO2 saved in 2020 per sold device (at home)

An average family emits 43 kilograms of CO2 each year through its total tap water consumption. For bottled water this is 300 times as much. For each tap water cooler sold, AQUALEX thus reduces emissions by 12,900 kilograms.

Number of lorries taken off the road in 2020

An AQUALEX device supplies you with around 5,200 litres of tap water over a period of 10 years. For every 5 devices that AQUALEX sells, one truck is taken off the road. Assuming an office setting where 20 people drink tap water (good for 2,600 litres per device per year), one sold device is enough to have one less truck on our roads!

Calculation

26,208 litres of water per truck / 5,200 litres of tap water consumed per water cooler over a period of 10 years = 5 water coolers take one truck off the road
