Reduction of the plastic continent?

It is precisely the urgency to get out of this perverse logic that leads to reject this type of solution, as you have clearly stated: pollution control is an activity "which is part of the logical extension of the former (the polluters )! ... And: "the proposed technical solution intervenes downstream of the pollution, and it would make good sense to attack its source".

Well it starts. With the ban on plastic bags in store cases. It is for January 2016.

it is not the ban on plastic bags in stores in rich countries that will change much the amount of plastic in the trash

I happened to recover the used pallet from the transporter to serve as firewood: it was incredible to see the quantity of plastic to evacuate ... in general polyethylene film which burns very well without polluting

the first thing to do to avoid all these plastic particles degraded by the light which are carried away by the water towards the sea, is to give it a real value of fuel! it is easier to make energy with almost new polyethylene than with that which is in the middle of the ocean

but for the ocean the damage is done ... we can dream of stopping the pollution at the source, but it remains useful to take care of what is already at sea ... when we shit in our pants is no longer useful to tighten the buttocks

Absolutely agree with your observation ...

As for this process, if it has already proven its effectiveness in siphoning portfolios, let's wait to see what it will give at sea, in far more demanding conditions, because reality is completely indifferent to marketing ...

Among the polluting economic aberrations, I have just heard that sachets in sachets represent, on the one hand, a huge commercial success, and on the other hand, a real pollution problem because there is currently no recycling technique for the container, this famous semi-plastic half-aluminum sachet that we find today abandoned everywhere.

One of the first measures to be implemented upstream would be to oblige that when an industrialist launches a new product on the market, all the elements of the product or its packaging can be recycled, or even better: biodegradable.

Biodegradability remains problematic because, to my knowledge, the materials which claim this property are only partially so.
This means that part of the components are metabolized in the soil by the action of microorganisms, releasing the other components * which remain intact in a very fragmented form which illusions but accumulates, much like plastic waste. at sea, which ultimately reduce to huge masses of very fine particles that the young Dutch system can never recover (assuming that this is the case for the largest waste, which is very doubtful: there is a big difference between what is desirable and what is possible).

* These materials are a mix in which a "weak link" is introduced which will destabilize the assembly, it remains a rather approximate circumstantial tinkering.

biodegardable packaging is bad it can only be used once

I would prefer solid bags resistant to the sun so that we can reuse to store or transport anything we want: food use when the bag is new and then reusable for other uses then

the height is the bag sold for 1 euro in supermarkets that do not withstand light at all: if we store something in it, a few years later it cracks anyway

other packaging plastic: bottles and cans ... for example oil can: I always buy engine oil in black can: it resists the sun and can serve for a long time as a can of petrol or other fuel ... alas for a year I can't find it anymore: I mostly find gray canisters that no longer have the same resistance

when the packaging is solid and thick, when it is no longer used there is still value as a material to recycle or as fuel ... when it is too thin films it has no value

Recycling plastics: the numbers

17 March 2015

During the Matine Plastiques organized by MPE-MEDIA the 10 last March, Franck Seïté, deputy director of the Plastics division of the Paprec group, gave an update on the key figures of recycling in 2014.

Europe would have produced 25 million tons of plastic waste, of which 25% was recycled, 37% was used for energy recovery and 38% was buried.
In the same year, France produced 3,5 million tons of plastic waste, with the same proportion of landfill (38%), 20% in recycling and 42% in energy recovery. According to Paprec group figures, 60% of plastics are recycled for the manufacture of long-life products (automotive, construction, electronic equipment, etc.) and 40% for short-lived products, mainly for packaging .

Finally, concerning PVC, 3 the world's best selling plastic, its recycling reaches the record level of 470 000 t in Europe in 2014 and is in line with 800 000 t for 2020. The French figure is about 53 000 t recycled PVC in 2014.

there is a problem in these figures! 25 + 37 + 38 = 100%

It is not possible ! he forgot the amount of waste lost! precisely those who pollute the most

landfilling plastic waste is not a bad solution: better than incineration without producing useful energy ... with landfilling, waste remains available as fuel when it is needed

it gives 37% in energy recovery ... they forget what is incinerated without producing energy

These figures are very satisfactory: they just fall!
It is therefore not necessary that they correspond to something ... : Mrgreen:
