The plastic is (not so) great!

Environmental impact of end of life products: plastics, chemicals, vehicles, agri-food marketing. direct recycling and recycling (upcycling or upcycling) and reuse of good items for the trash!

60 to 70% plastic microparticles in seafood.
already they serve as consumers of our organic waste from our pits or sewers, it is a more even more ragoutant.
The solution? the VGL at the beginning of the food chain and not the end. Enjoy your meal! :?

What does this figure mean :?:
Percent what :?:

70% of the mass of a seafood is plastic :?: or 70% of the volume :?: I do not think so...

When you know the volume of water needed to make (or recycle) paper, the disposable paper bag is a less good solution than the reusable plastic bag (but better than the disposable plastic bag).

I do not know the difference on the eco-balance of water VS plastic bag paper bag: do you have the figures to the mass made?

Then in terms of the environment, everything depends on what we are talking about: here, it is the pollution of the environment by the waste which was the subject and not the manufacture ... and here the paper is 100% winner !

+ 1 it seems to me, very very, exaggerated!

Even 6 at 7% by mass would be VERY HUGE : Cheesy:

A terra-eco study.

Yes, everything depends on what you're talking about ...

Food law: straws and plastic tins soon banned?

By Le Figaro.fr with AFP

After single-use bags, the coffee and straw tacks, which eventually swell the plastic continents in the oceans, may be banned in France from the 1 January 2020.

Toulouse: Finally a study on the impact of plastic pollution on rivers and fish

The 19 / 10 / 18

Plastic pollution carried by rivers is a scourge. But its scale and impact on biodiversity remain a mystery. CNRS researchers are tackling the subject by making the Garonne a giant laboratory ...

Two Toulouse laboratories of the CNRS have just embarked on the PlastiGar study (for Plastique Garonne). Scientists estimate that between 8 and 15 millions of tons land in the ocean each year, but no study has so far really quantified this pollution, nor evaluated its impact on biodiversity.

The objective of the laboratories is to quantify "the spatial and temporal variations of microplastic concentrations" in the river but also to know if the pollution is transmitted in the food chain when it is ingested. In fact, recently microplastics - pieces sometimes invisible to the naked eye, resulting from the fragmentation of larger waste - have been found in half of the invertebrates of rivers in Wales.

Fish will regurgitate

This new information fishing will last three years, in a laboratory of 200 kilometers long. From the purified waters of the foothills of the Pyrenees to Agen, fourteen sites were selected in all, supposedly "little or very contaminated". The first nets to capture and filter microplastics in water or mud were strained on Monday October 15.

"We wear them, we wait by the side, and we sort them by hand," says Alexandra Ter Halle, a physicist and chemist at the Laboratory for Molecular Interactions and Chemical and Photochemical Reactivity (IMRCP-CNRS / UT3). Except that these nets have meshes very, very fine, up to 25 microns in diameter.

Sampling on biodiversity
The samples, collected four times a year, will then be analyzed in the laboratory. At the same time, samples will be taken of biodiversity: "We will analyze microalgae, like diatoms, and we will compare those that develop on rocks or plastic cans," says Julien Cucherousset, research officer at the Evolution and Biodiversity Laboratory. (EDB, CNRS-UT3).

Not to mention the fish that will have to "regurgitate their food bowl" ... or lose a fin. The final results will also give responsibility for Toulouse and its agglomeration in this plague.

PLASTIC SOON WILL BE THE FIRST OPPORTUNITY OF THE OIL INDUSTRY BEFORE TRANSPORT

16 Oct 2018 Novethic

The demand for plastic will explode further in the coming decades after having already doubled since 2000. The International Energy Agency (IEA) projects that petrochemical production will increase by 60% by 2050. By that time, more oil will be used to make plastic than to drive cars, planes or trucks.

Little by little, big cities are committed to prohibiting the most polluting cars, running on diesel or petrol to fight against climate change. But this effort masks the rise of another sector that weighs heavily on the environment: petrochemicals. To meet the demand for plastic, the oil industry still has a bright future.

According to a study by the International Energy Agency (IEA) published October 5 (1), global petrochemical production will thus increase by 30% by 2030 and 60% by 2050 to reach 1 billion tonnes, equivalent to the current production of steel or cement.

Growth is on the side of developing countries that will increase their consumption of capital goods, but also of fertilizers or clothing. India or Africa today consume 20 times less plastic and 10 times less fertilizer than developed countries.

Blindside

“This is one of the blind spots in the energy debate,” emphasizes Fatih Birol, director general of the IEA. “Our economies depend heavily on petrochemicals, but the sector receives much less attention than what it deserves. Yet our analysis shows that they will have a greater influence on the future of oil demand than cars, trucks and aviation. "

Since 2000, the demand for plastic has already doubled and by mid-century, petrochemicals will absorb nearly half of the growth in oil demand. At this rate, the planet will consume more oil to make plastic than to drive cars. And the industrialists have understood it well. The French group Total and the Saudi Saudi Aramco announced last spring the construction of a petrochemical site in Saudi Arabia, for five billion dollars.

Plastic waste

Although petrochemicals emit less CO2 than transport, its development will be such that it will contribute to global warming significantly. Experts estimate that sector emissions will increase by 30% by 2050. In addition to the impact on the climate, petrochemicals also contribute to the pollution of air and water. And above all, it poses an incredible challenge: that of the thousands of wastes that will end up mostly in the oceans. Only 9% of plastic produced since 1950 could be recycled and 12% incinerated.

Now the ocean seems to be waiting for its limit to absorb these materials whose lifespan is spread over centuries. This summer 60 tons of plastic waste have been removed from the stained beaches of Santo Domingo. At the same time, high tides were throwing 12 000 tons of waste into Mumbai. Plastic bags have even been found in the bottom of the Marianas pits, the deepest point of our oceans.
