1. Current status of plastic waste
Plastic waste is defined as products made from plastic, difficult to decompose in the environment and used, including bottles, plastic bags, old toys, etc.
Plastic waste can arise from a variety of activities such as:
Plastic waste from daily life in residential areas, markets..
Plastic waste from industrial, manufacturing, construction activities…
Plastic waste in hospitals, medical facilities…
Plastic waste from tourist areas, services …
Every year, according to statistics, the world generates more than 300 million tons of plastic waste, of which 8 million tons of plastic waste are dumped into the ocean. According to a report by the United Nations, the amount of plastic waste each year is enough to surround the earth four times.
According to research results from the University of Georgia, Vietnam is one of the 20 countries that emit the most garbage, and one of the five countries with the largest amount of plastic waste in the ocean in the world. Every year, Vietnam discharges about 1.8 million tons of plastic waste into the sea.
With such a worrying plastic waste situation, it is essential to pay attention to the decomposition time of plastic in order to know how to regulate usage.
Products made from plastic will have different decomposition times because the structure and materials that make up each product are different. But in general, the decomposition time of plastic is very high, up to 1000 years.
The decomposition time of plastic from products from traditional plastic bags often lasts up to thousands of years.
Material: Made from High-Density Polyethylene (HDPE), which contains many neurotoxins, carcinogens and hormone-disrupting chemicals.
Decomposition time: 10 – 100 years depending on ocean environmental conditions and can only be decomposed under the influence of sunlight.
Harms to human health and the environment:
Causes asthma, obesity, cancer… when used to preserve food.
When released, toxins in packaging and plastic bags enter the ecosystem, contaminating the soil, groundwater, and air. Increased risk of diabetes, liver toxicity, heart disease, thyroid disease and neurological disorders. For children: can cause lung disease, asthma, increase insulin resistance and high blood pressure, cause obesity, diabetes, kidney and heart complications.
For women: toxic substances in plastic bags and plastic bags can interfere with the hormonal balance, affecting reproduction.
