2,400 fewer plastic bottles a year, thanks to a single decision

A simple calculation with a big impact

Imagine a typical German household. Four people. Each drinks the recommended amount of water: at least 1.5 litres a day. That’s six litres a day, 42 litres a week, over 2,000 litres a year. Just for drinking. On top of that, there’s water for tea, coffee and cooking. A realistic estimate: a four-person household uses three to four crates of water a week.

Now let’s do the maths: four crates times 52 weeks equals over 200 crates of water a year. Each contains twelve bottles, that’s over 2,400 plastic bottles. Even if many of them are reusable: they have to be produced, filled, transported, returned, cleaned and transported again. Every single bottle has an ecological footprint: from production through transport to disposal.

Even reusable bottles aren’t the solution

Many people argue: “I buy returnable bottles.” That’s better than single-use, no question. But even reusable bottles have a significant ecological footprint. On average, they are refilled fifty times before being replaced. Each time, they must be collected, transported, cleaned (with hot water and detergents) and refilled. Each of these steps consumes energy and water. The German Environmental Aid organisation has calculated that even reusable glass bottles still generate significantly more CO₂ per litre than tap water. And reusable PET? Even more, because the bottles can be reused less often than glass.

What a single Kini changes

A MAUNAWAI Kini water filter jug replaces all of that. It sits in your kitchen, is filled with tap water and delivers living water of spring water quality. No lugging. No transport. No plastic. No bottle cleaning cycle. A filter cartridge lasts two to three months, which equates to four to six cartridges a year. Compared to the 2,400 plastic bottles, that’s a reduction of over 99 per cent in packaging material.

And the cost? A crate of mineral water costs around five euros. At four crates a week, that’s 20 euros; over a year, that’s over 1,000 euros. The Kini costs 90 euros to buy, and the cartridges around 90 euros a year. The saving is over 800 euros a year. That’s not a luxury. It’s a smart decision.

The invisible transport route

What many people don’t realise: behind every bottle of mineral water lies a long production and transport journey. The water is bottled at the source, often hundreds of kilometres from your home. It is loaded onto lorries, driven to supermarkets, and collected by you in your car. And the empty bottle? It travels the same way back. Or it ends up in the bin.

According to environmental organisations, one litre of bottled water generates up to 600 times more CO₂ than one litre of tap water. MAUNAWAI water comes straight from your tap: zero transport kilometres. The only transport involved is the delivery of the filter cartridge, which is delivered to you in a carbon-neutral way. A few grams of cardboard instead of kilograms of glass and plastic.

What you no longer have to do

Think for a moment about what changes in your daily life. No weekly trip to the supermarket to load heavy crates of water into the car. No stacking crates in the cellar or storage room. No hassle with empty bottles piling up before someone takes them to the bottle return machine. No reordering from drinks suppliers.

Instead: a jug on the kitchen worktop. Fill it with tap water. Wait until it’s run through. Drink. That’s all. The time you used to spend buying water is yours again. This isn’t just an environmental benefit, but also an improvement in your quality of life.

The bigger picture

If just 10,000 households in Germany switched from water crates to MAUNAWAI, that would mean 24 million fewer plastic bottles per year. 24 million fewer bottles that need to be produced, transported and disposed of. That’s thousands of tonnes less CO₂, thousands of cubic metres less waste, thousands of litres less oil for plastic production.

And it goes further: fewer lorries on the roads, less noise, less particulate matter, fewer traffic jams. The infrastructure for bottled water (bottling plants, warehouses, transport networks) consumes a great deal of energy and resources. Every household that switches to filtered tap water takes the strain off this infrastructure.

This is no utopia. It’s simple maths. And it starts with a single decision: the decision to choose living water from your own tap.

What it means to be lucky enough to live near a spring

Maria Knoch, the founder of MAUNAWAI, once put it this way: very few of us have the good fortune to live near an unspoilt mountain spring. But with MAUNAWAI, you can produce exactly this spring water in your own home, without unnecessary transport, without plastic, without a guilty conscience. Wouldn’t it be wonderful to be able to produce your own spring water at home? That is precisely our mission.

And this mission has a dual benefit: if you drink good water straight from the tap, you no longer need bottled water. If you no longer need bottled water, you generate no plastic waste, no transport emissions and no logistics costs. Good for you, good for the environment. A decision that benefits everyone.
