Why should milk not be stored in clear glass bottles?
Clear glass fails to block light, and introduces significant amounts of oxidation to milk. … Grocery store lights make this even worse for milk, as the brighter lights used to display the dairy aisle allow more light to get in and these nutrients to break down even faster.

What are the problems with plastic?
But the problem with plastic is that most of it isn’t biodegradable. It doesn’t rot, like paper or food, so instead it can hang around in the environment for hundreds of years. Each year, 400 million tonnes of plastic is produced and 40% of that is single-use – plastic we’ll only use once before it’s binned.
What are the cons of glass?

What is the strongest glass?
What Type of Glass Is the Strongest?Toughened (tempered) glass: This kind of glass is recommended for safety purposes.

How can you tell if glass is safety?
If you try to view tempered glass in sunlight with a polarized pair of sunglasses, you will see dark, shady spots or lines stretching across its surface–a prime indicator that the glass is toughened. These lines were formed by the machine rollers during the tempering process.
What type of glass is best for Windows?
Tempered glassTempered glass, also called safety glass, is the smartest choice for windows and other glass structures in your home. Tempered glass is heated and then cooled very quickly during the manufacturing process; this rapid change in temperature makes it about four times stronger than untreated glass.
Why is glass expensive?
Not only is glass more expensive to ship, it also costs more to produce primarily due to the amount of heat required during production. Glass manufacturing is energy-intensive accounting for 1% of total industrial energy use in an Energy Information Administration (EIA) survey of the manufacturing sector.
What are the benefits of glass?
The benefits of glass packaging are clear: it’s sustainable, it’s inert, It’s 100% and infinitely recyclable, reusable and refillable; it’s safe to store food and drinks in; and it’s beautiful, consumers love it. Glass is made from naturally occurring ingredients abundant in nature.

Why is glass bad?
The major environmental impact of glass production is caused by atmospheric emissions from melting activities. The combustion of natural gas/fuel oil and the decomposition of raw materials during the melting lead to the emission of CO2. This is the only greenhouse gas emitted during the production of glass.
