The idea of a carbon sink is a bit misunderstood here. The idea of a carbon sink is a reduction of carbon that comes from the atmosphere. It must “fix” carbon that is already in the air. Trees are a carbon sink, for the most part, because their mass is made of of carbon obtained from The atmosphere. Unless the plastic formation process you are thinking of is ...

Many animals can eat through plastic to get to what they really want to eat. Among them: termites, mice and myself when battling against a candy wrapper. However, as far as I understand, none of them can degrade the plastic. You can do the test yourself and I'll guarantee the plastic wrapper will come out the other end of your digestive system. ...

Some simplifying assumptions This is quite a broad and complex question to answer, so I'm going to simplify it shamelessly to make it a little more answerable. Firstly, there are a huge number of different plastics with a huge variety of physical characteristics. You mention that you're interested in ‘the most common type of plastics’, so I'm going to ...

About 18.2 million tons sink to the ocean floor. Every year, an astonishing 260 million tons of plastic waste is produced, and about 10% of it ends up in the ocean. Over time, roughly 70% of the plastic that ends up in the ocean sinks to the ocean floor. Therefore 18.2 million tons of plastic waste end up on the ocean floor. I used this article for my ...

Plastic is a much less efficient carbon sink than the original crude oil if it had been left in the ground or any natural method for storing carbon such as peat bogs. It is still technically a carbon sink but is starting to be broken down naturally so is not a renewable or sustainable one. Pollution and green house gasses are a major part of plastic ...

Most plastics are made from the already-sunk carbon of crude oil or natural gas, and as a result, can be at best carbon neutral. However, bioplastics such as cellulose acetate or polylactic acid are derived from plant sources; the carbon here comes from the atmosphere, and they can theoretically act as carbon sinks. However, even if we switched all our ...

I take it that your iron balls are hollow and made of rust resistant steel. It would be a fiendishly expensive project, but I doubt it would have the result you suggest. The iron balls would have to be linked together by chain or rope to prevent them dispersing in ocean currents and ending up on beaches around the world, like the cargo of plastic ducks which ...
