Glass weighs more than plastic and fractures considerably more readily in shipment. This implies that it emits more pollutants and costs more to transport than plastic. Another factor to consider is that most glass is not recycled. Colored glass can only be recycled and melted down with glass of the same hue. Clear glass can only be recycled with other clear glass.
However, plastic is 100% recyclable and emits fewer pollutants when burned. Additionally, burning plastic produces less heat than oil or natural gas for use in heating homes and businesses during the winter months.
The main advantage of recycling glass is that you get a second chance at making money. There are several companies that will buy used glass bottles in bulk. You can find work cleaning and preparing glass for re-use.
Plastic cannot be recycled into anything else but plastic. However, almost all plastic does not go into landfills after use. It is either recycled or incinerated depending on its material type.
Incineration is the only sure way to destroy all plastics completely; however, this does cause pollution. Burning plastic creates carbon dioxide and monomers that can be toxic if not treated properly.
Recycling plastic reduces its volume by half and returns it back into the market as new product. This also means it saves energy and materials compared to throwing out plastic containers.
Finally, glass takes one million years to degrade in the environment, and maybe much longer in a landfill. Plastic does not decompose easily and can leach harmful chemicals into the soil or water supply.
However, plastic is both lighter and thinner than glass. It is also less likely to break or be damaged during transportation. These advantages make plastic the material of choice for shipping products across long distances or through the mail.
The main advantage of glass over plastic is its ability to break without losing its shape. This makes glass useful for products that may be dropped or exposed to sudden forces such as when using chopsticks to eat noodles. Plastic loses its form when subjected to mechanical stress and cannot be used for products that require precise dimensions.
Products that use glass need to be manufactured with this fact in mind. Glass cuts easily and requires careful design to avoid accidents with knives or saws. Glass objects are also very fragile and should be handled carefully or not at all. While lifting heavy items by yourself is unlikely to hurt you if you're standing up, if you're sitting down then you should get help from someone who knows what they're doing.
Plastic objects do not need to be specially made for shipping.
Glass is more heavier and less durable than plastic. This reduces the cost of transportation. It also has a lower carbon footprint because it requires fewer journeys and less packaging material. Furthermore, because plastic is more flexible than glass, it is simpler to shape, allowing businesses to develop identity. The main advantage of using plastic over glass is that plastic does not break. This makes it ideal for products such as milk or juice where its undamaged appearance is important.
There are several advantages of using bottled water instead of tap water including having clean drinking water at all times, no risk of disease, and less expense. Bottled water is usually cheaper than tap water because it doesn't have to be transported any distance nor do they need to make any alterations to the source water. Also, bottled water companies don't have to invest in water treatment facilities since that would be unnecessary with respect to selling drinks. Finally, there is a concern about the quality of tap water but this is rarely an issue with bottled water because they are tested before they are released for sale.
Disadvantages of bottled water include the impact of their use on climate change due to manufacturing processes and transportation, and the fact that they require natural resources such as oil for their production.
Bottled water sales contribute to environmental problems including landfills, pollution, and the destruction of natural habitats. Plastic bottles can take hundreds of years to decompose. This adds to landfill waste.
