ask pablo - pet manufacturing process
Dear Pablo, I have always heard that bottled water is the scourge of the Earth.
But it's really convenient.
So what's wrong with it, no doubt, do you have any good alternative suggestions? Over the past year, there has been a growing momentum of denigration of bottled water.
This is a topic that is often discussed in news and city council meetings.
San Francisco city has suspended the use of city funds to buy bottled water when tap water is supplied, and recently, the TV program, the Boston law, gave a monologue in court on the environmental drawbacks of bottled water.
We all know that bottled water for bottled is built on clever marketing, but let me get a deeper look at these numbers.
First of all, the manufacture of plastic bottles is usually made of raw materials that are not recycled and require a lot of oil, and only 12% of this material is recycled for recycling.
Total Quality of empty 1-
About 25 grams of bottle (
This varies from brand to brand)
It's made with pets (
Pet). One kilogram (1 kg = 2. 2046 lbs. )
This type of plastic takes about 6.
5 kilograms of oil and 294 kilograms of water (
Including cooling water of Power Plant)
, And results in 3.
7 kilograms of greenhouse gas emissions.
According to my calculation, an empty 1-
The bottle requires more than 7 liters of water in the manufacturing process, using 162 grams of oil, resulting in more than 100 grams of greenhouse gas emissions. (
About 10 balloons full of carbon dioxide, or how much carbon dioxide an average car emits in half a kilometer or more --The third mile of a mile. )
Next, distribute bottled water, usually via a container ship from the other side of the Earth (
Fiji, Evian, Saint-peregrinno)
It is fuel-intensive and can lead to emissions of greenhouse gases and sulfur dioxide.
Greenhouse gas grams for transport emissions (in carbon-dioxide-
Per metric ton per kilometer
Container transportation emits about 17 grams of carbon dioxide per ton of kilometers, trains emit 56 grams of carbon dioxide per ton of kilometers, trucks emit 102 grams of carbon dioxide per ton of kilometers, and 570 grams per ton of kilometers.
Therefore, the important factors of transport emissions are weight, distance and mode of transport.
Because we can't change the weight of bottled water, the company automatically selects the most efficient and economical bottled water
Effective means of transportation, we can control the distance through the choice of consumers.
The sale of bottled water is driven by marketing, which creates a sense of luxury, quality and novelty.
After all, every brand has a taste of water.
But you spend a lot of money and look around town with that cool Fiji square bottle or the obvious green Perrier bottle.
When you add the cost of packaging and marketing to shipping, not to mention the huge profit of the water merchant, the price of a bottle of water is two to five times that of the same amount of gasoline.
The price of bottled water is up 50,000 compared to the price of tap water (
Many brands take water from municipal water supply).
Given the lack of access to clean and safe drinking water for millions of people around the world, bottled water is also a major ethical dilemma.
Currently, more than 1-
Of the world's population, the sixth, or about 1 billion, is often lacking safe and clean drinking water.
Of our $ 20% annual bottled water spending, only 75 billion can meet the drinking water needs of less fortunate people around the world.
If we assume that a well is needed to meet the minimum needs of about 100 people, and if we assume that the average cost of a well is $1,500, then we need to spend $15 billion worldwide.
Based on these assumptions, we spend five times more on bottled water each year than on eradication 1.
Every year, 8 million children die from water-borne diseases.
Without compromising convenience, quality or health, there are many options to break the habit of bottled water.
By purchasing local bottled water from around the world, not bottled water, and even by switching to tap water, you can significantly reduce greenhouse gas emissions from drinking water consumption.
Try to carry refillable containers made of aluminum, plastic or stainless steel.
Out of image awareness, companies like Klean Kanteen, Sigg and nargene are ready to meet your hydration needs with stylish reusable bottles.
