Sky Ocean Rescue: Spanish fishermen find new way to clear oceans of plastic

Three miles off Spain's Costa Blanca, Vicente Sana and his crew pull in their first catch of the day, but as the nets are opened onto the deck, plastic and rubbish tumbles out with the fish.

Fisherman Paco Perez points out a bit of old tyre, a diver's fin, water bottles and yoghurt pots.

He tells me this is normal, that they're seeing more plastic in the Mediterranean now than in the past.

"Why?" I ask.

"I don't know," he replies. "I guess people are throwing away more, but we notice it more in the summer."

A recent survey by Greenpeace found 96% of litter floating on the surface of the Mediterranean was plastic. Globally, it is estimated that as much as 12.7 million metric tonnes of plastic enters the ocean each year.

Vicente and his crew, along with about 2,000 fishermen in Spain, are now working with clothing company Ecoalf to turn plastic found in the sea into fabric.

"We make our living from the sea so we have to clean it up," he explains. "Everything we catch, instead of throwing it back, which would be easy, we just separate into bags and in the afternoon we deposit them in the container."

Environmentally, working on a trawler causes controversy, so some of them see the project as doing their bit.

The rubbish that is collected onboard is thrown into bright yellow bins in the port. The plastic is then separated and taken by Ecoalf to be broken into chips and then pellets, which can eventually be spun into thread.

The end results include jackets, trainers and backpacks - all made from recycled plastic.

At the company's store in Madrid, founder Javier Goyeneche explains how his dismay at the amount of waste produced by the fashion world made him want to make a clothing line that was more sustainable.

So far they have transformed 30 million used bottles into material but Mr Goyaneche says the pollution is widespread: "We did a trial test with a thousand divers (in Thailand) in January and we took 7.5 tons of waste in one day out of the ocean, 7.5 kilos per diver.

"It's not a problem of Spain or of Thailand, it's the same problem in Mexico, Columbia, in Hawaii. This is a worldwide problem."

Of course, it is not just fish swimming with plastic. Thousands of holidaymakers pack onto the popular beaches of the Costa Blanca each year.

The fishermen tell me tourism had increased the pollution in the sea.

The fishermen's livelihoods depend on cleaning up the water. The pollution is killing off their product. In Vicente's words: "No fish means no work."

The rest of us won't go untouched; the plastic that is filling up our seas will eventually end up on our plates.

Sky News launched its Sky Ocean Rescue campaign earlier this year aimed at reducing the amount of plastic waste that ends up in the world's seas.
