As an alternative to plastic bags, the use of which cut worldwide, manufacturers are increasingly offering so-called eco or Biobags.
AiF.ru learned from the head of the environmental movement "Separate collection" Tatiana Nagorskaya whether ekopakety do not cause environmental harm to the environment and indeed whether they can be considered as an ideal, and above all, safe for the environment by replacing plastic.
What is ekopakety?
Under ekopaketami understood as biodegradable bags (made from starch and similar natural materials) and made of oxo-biodegradable plastic. Some activists of "green" as a separate category of hydro-biodegradable bags - paper.
On the market today is represented by two types of polymers, which, as manufacturers claim, decompose faster, rather than ordinary plastic bags. According to Greenpeace toxic expert program and the "Package of the project? - Thank you, no! ", According to environmental policy expert Alexander Ivannikov if plastic bag decomposes many hundreds of years, certain types ekopaketov - about 180 days. However, this does not mean that they are safe for the environment. So, oksorazlagaemye polymers, though split into small pieces a few months, but will still leave behind microplastics that pollutes nature.
Regarding biodegradable polymers, they are produced from corn or potato starch, cellulose and soybean. Yes, they are not toxic, but their utilization desired public collection system for organic waste composting plant or individual home composting systems.
Why ekopakety - is not an option?
"At the moment in the world in general and Russia in particular on all sides there is an attack manufacturers any kind of degradable material, packaging and on retail. They all prove that their products are good, because it is decomposed or degraded conditionally. But no amount of disposable packaging, instead of the other one-time can not be considered environmentally friendly, "- said Tatiana Nagorskaya.
The expert adds that in Russia there are no standards that would determine what is of a biodegradable package decomposition technology and what exactly are its members. Often, according Nagorskaya, there will still contain polypropylene, but the manufacturer makes no mention of it.
Furthermore, even when it comes to bags made of biodegradable polymers, they will still fall or in a landfill or in an incinerator. "Packages that are made from starch must be subjected to the composting industry. They can not just throw in a landfill, so they decompose in a year, they have to be specially aerated to the decomposition process was faster. But the fact is that the conditions inside the landfill, anaerobic (airless). Accordingly, then, these materials will be a source of methane - a greenhouse gas that is 20 times stronger than CO2 (carbon dioxide), "- says Nagorskaya.
For competent processing needs well-honed system of dealing with organic food waste, composting, and in Russia it is practically not. "And so when we decide which package to use, it is necessary to proceed from the fact that one can not be a one-time change to another, you need to completely give it up. The correct solution - do not use bags at all. Yes, it is inconvenient. We are not used. But the environment is best done that way "- sure Nagorskaya. According to the expert, the alternative to disposable bags can be reusable shopping bags, special bags ( "fruktovki"), used paper bags or paper.
