The use of plastic goods, especially in the food packaging and storage industry, is increasing day by day due to its low weight and high mechanical strength, cheap raw material, and easy storage and transportation of plastic bottles. In this article, the effects of plastic bottles from medical, environmental and energy consumption aspects are compared and compared with glass bottles.
According to the reported statistics, the consumption of plastic bottles in Iran is expected to increase to more than 92,000 tons this year. Biodegradability, recycling and reuse with low quality of these bottles have made them unable to be a suitable place to store food. The release of toxic compounds into the environment, especially into the air during the production process, the release of various toxic compounds such as antimony, zinc, bromide derivatives, dioxins and phenols are destructive effects that these bottles will have on the environment and humans. Also, the use of these containers is not cost-effective due to various problems in recycling and high cost for dumping waste from plastic bottles.
In contrast, glass bottles are made of minerals that can be easily and cheaply recycled (15 to 20 times) so that recycled glass bottles have the same quality as the original bottles and also They need less energy than the original energy to produce. Glass bottles can be a safe place to store food.
