It's not just that gyre of plastic that I'm concerned about it's the gyre of plastic in the supermarket.

We had to replace them with recyclable plastic.

Moreover, most plastic products are made from so called petroleum based commodity thermoplastics. Given that a non renewable resource forms the basis of many plastic products most of which will not last long current plastics usage patterns are not sustainable.

Such developments would encourage industry to re use or recycle more parts. Although all 40 kinds of plastics used in a North American automobile can be recycled, the need to separate and clean them makes using them more expensive than using virgin plastic resins.

Although all 40 kinds of plastics used in a North American automobile can be recycled, the need to separate and clean them makes using them more expensive than using virgin plastic resins. This translates into a higher proportion of plastics in the remnants of shredded end of life automobiles a contaminated mixture of plastics and non plastics that is usually disposed of through some combination of landfilling, incineration, and secondary recycling.

Closed loop recycling, in which plastics waste is used to make another product, thus carries significant environmental benefits, such as reduced energy and oil consumption. But the process of separating the petroleum based recyclable plastics from other kinds of plastics and solid waste is difficult, costly, and labor intensive, so only a small proportion is recycled.

Each of these methods recovers a different amount of the embodied energy of the plastic item. (All of the embodied energy is lost if the plastics are landfilled, a common disposal method worldwide.)

There are four categories of plastics recycling primary recycling, in which the plastic is re used in the same application secondary recycling, in which material (mixed or contaminated) is used in less demanding applications tertiary recycling, in which the plastic is converted into monomers or chemicals and quaternary recycling, in which only energy is recovered through incineration. Each of these methods recovers a different amount of the embodied energy of the plastic item.

It is down cycled and turned into lesser things, while a glass bottle can be a glass bottle again or can be used again a plastic bottle can never be a plastic bottle again.

Plastik

At the end of this process, we have a mixed plastic composite many different types of plastics and many different grades of plastics.

In a world that is reliant on plastics, more sustainable production, consumption, and disposal of plastic products is crucial. Civil society, industry, and government must work together to increase the share of recycled plastics, thereby ensuring that plastics costs do not outweigh their benefits.

It's a bad thing that plastic breaks down into smaller little bits, because it's always still plastic.

It's plastic pollution.

He's given a little bottle massage, a little bottle medal.

Whenever possible, refuse single use and disposable plastics.

Upon educating myself a little further about plastics, I actually realized this was a bad thing.

In fact, they may threaten the secondary recycling of petroleum based plastics, owing to possible contamination during sorting of mixed streams. And critics have expressed concern about the environmental impact of corn and other crops grown for industrial purposes, such as plastics and ethanol production, not to mention the potential effects on global food prices.

I'm also concerned about the plastic in the refrigerator, and I'm concerned about the plastic and the toxins that leach from plastic into us and into our bodies.

And the very first CAD model we made, the surgeons were playing with the plastic model, couldn't quite figure it out.

We push that material to extruders where we melt it, push it through small die holes, make spaghetti like plastic strands.

To exchange environmental models among the countries, sharing information.

Plastic just is not going to do it.

And part of that is that we had to model very rapid circulation of CO2 and oxygen and water through this plant system.

And if you really look into it, particularly when it comes to plastic bottles, most of it is only down cycled, or incinerated, or shipped to China.

Ethylene oxide

After 20 years, we see emerging the debris accumulation zone of the North Pacific Gyre.

Now because the plastics are so plentiful and by the way, those other methods don't lead to the recovery of plastics, obviously but people do try to recover the plastics.

I began talking with people who actually had been out to the gyre and were studying the plastic problem in the marine environment and upon doing so, I realized actually that cleaning it up would be a very small drop in the bucket relative to how much is being generated every day around the world, and that actually I needed to back up and look at the bigger picture.

And both in the production of plastic, the use of plastic and the disposal of plastic, the people who have the bull's eye on their foreheads are poor people.

It's a plastic bag.

The Dirt on Plastic Waste

Given the difficulty and expense of separating plastics, the most economically viable option is often secondary recycling of a few commodity thermoplastics mostly bottles, for which collection infrastructure is already in place. More economical separation methods are crucial to expanding the scope of plastics recycling, as is the identification of new potential markets for the recyclates.

It's mostly many types of plastics and many types of metals.

Plastics have taken the place of many conventional materials.

Recycling of plastic in many developing countries means the incineration of the plastic, the burning of the plastic, which releases incredible toxic chemicals and, once again, kills people.

And in the process, we started recreating how the plastics industry makes plastics.

Barbarically, we're killing sharks for shark fin soup, undermining food chains that shape planetary chemistry and drive the carbon cycle, the nitrogen cycle, the oxygen cycle, the water cycle our life support system.
