From time to time, each of us uses
disposable tableware.
Some do it almost every day (take at least
cups of coffee in vending machines), others
– from time to time, for example, on picnics.
Supporters of disposable tableware say:
"It's cheap and convenient!"
Opponents: "It pollutes the environment!"
We say:
"Use bioprovessels!"
What is the danger of ordinary
Researchers from different countries do
not stop talking about the dangers of using
plastic tableware.
There are several reasons for this, let's
name the main ones:
Firstly, disposable plastic over plastic, a
chemical reaction occurs. As a result,
toxins are released that enter the body
along with food. Their accumulation leads
to the development of various diseases:
allergies, metabolic disorders, impaired
reproductive function, various hormonal
disruptions in the human body, the vessel
contains potentially dangerous substances
for health.
Secondly, plastic negatively affects the environment.
The period of its decomposition in natural conditions
reaches several hundred years – and all this time harmful
substances are released into the water and soil.
In addition, plastic is a danger to birds, fish and animals,
taking plastic particles for food, they eat them, which often
causes the death of animals.
What is plastic tableware made of?
Ordinary disposable tableware is made of
three basic materials:
Polyvinyl Chloride
Each of these materials is potentially
dangerous to human health!
Polystyrene , when heated , emits
styrene toxin
 Polyvinyl chloride – releases
vinyl chloride, which is
the strongest carcinogen.
 Polypropylene – formaldehyde and
Each of these secretions is essentially a
Alternative: biodegradable plastics.
Oil, coal, natural gas – it is from these natural
resources that 99% of polymers from plant raw
materials are made today. And this despite the fact
that in the middle of the last century, the process of
obtaining polymers from vegetable raw materials was
invented. Now the production of plastic from vegetable
raw materials is gaining momentum. This is explained
by the fact that oil reserves are not unlimited, and for
the environment, the production of plastic from
vegetable raw materials is much safer.
Advantages of bioplastics tableware.
Safe for the environment. The term of
decomposition of bioplastics in the natural
environment is 180 days, while other plastics
decompose up to several hundred years.
2. Non-toxic.
The process of production and decomposition
of traditional plastics involves the release of
toxic substances into the environment. In this
regard, bioplastics are safe for nature and
3. Reduces emissions into the atmosphere.
The extraction of raw materials does not
require the development of fossil fuel deposits,
and harmful compounds and greenhouse gases
are practically not released during production.
4. Easier to recycle.
Bioplastics recycling is a more efficient and
less energy–intensive process compared to
conventional plastics.
5. Wide operating temperature range.
Bioplastics allows safe storage of food in the
freezer, as well as heating food in the oven and
6. Ease of use.
Bioplastics tableware is durable and
Bio–vessels are, indeed, a revolutionary
solution of our time!
A variety of single-use bioprovessels are very
popular today.
Plates, forks, glasses, lunch boxes, bags are
very convenient to use on the road and on a
picnic – it's beautiful, convenient, and a
forgotten plate or fork will not harm the
