Efforts to clean up ocean waste have been stymied by the sheer size of the areas in which plastic is concentrated. Traditional cleanup methods using vessels and nets to collect plastic are too expensive and time-consuming to work. For a job as arduous as this, some disruptive innovation is needed, and 20-year-old Dutch entrepreneur Boyan Slat claims he has created just that. The Ocean Cleanup will passively collect plastic debris in the waters between Japan and South Korea. 

Columbia, Md.,-based W.R. Grace & Co. under its bankruptcy plan of reorganization, paid over $63 million to the US government to resolve claims for environmental cleanups at approximately 39 sites in 21 states, the US Department of Justice and the EPA announced today

A 19-year-old Dutch student had a bright idea for ridding the sea of floating trash -- and now he's built a team of 100 people and is raising $2 million to fund his invention. The system uses long, floating barriers to passively guide floating trash to collection areas and is said to be capable of eliminating all waste larger than 1 millimeter

Lowe's, Lumber Liquidators, and Menards are also phasing out PVC rife with lead, cadmium and phthalates. 

Efforts are underway to develop plans for cleaning up the world's marine garbage patches, but the scale of the problem makes conventional cleanup technologies impractical. What's really needed is a change in attitude among the people producing the waste in the first place, writes Anja Krieger. "Redefining what kinds of plastic products we really need, and how to regulate, use and dispose of them, will be at the core of the answer," she argues.

Japanese scientists are preparing to launch a satellite that will use a 300-meter electromagnetic tether to snag orbiting trash left over from past satellites and space missions. The magnetic field will slow the trash, causing it to gradually fall closer to Earth and eventually burn up in the atmosphere. It's thought there are tens of millions of trash fragments in orbit around the Earth.

ESA's Clean Space initiative is looking at developing a satellite that can rendezvous with space debris and render it harmless by netting it like fish. According to ESA, there are 17,000 trackable objects larger than a coffee cup orbiting the Earth and many more down to the size of paint chips. This may not seem like anything very dangerous, but at orbital velocity, even a paint chip can hit like a bullet and a steel nut has the impact of a hand grenade.

For thousands of years humans have existed on Earth, but it is only in the last 100 or so that plastics have entered our lives. These days you can barely go a minute without touching something made from some kind of plastic. But while we've been getting all swept up in the convenience that synthetic polymers bring us, the trash has been piling up. Millions of metric tons of plastic enter the ocean every year, and no one really knows where it is and what damage it is causing. So ... what are we to do about it?
