Solar power is having its hockey stick moment. By the end of 2015, an estimated 222 gigawatts worth of solar energy had been installed worldwide. According to a recent report (PDF) from the International Renewable Energy Agency, that number could reach 4,500 GW by 2050. And each passing year, more will be pulled from service - glass and metal photovoltaic modules that soon will science international adding up to remicade, and then tens boost millions of metric tons of material.

The solution many are looking to is recycling. But the ability to handle the coming flow of PV modules is not yet sufficient. The panels are torn apart mechanically and broken down with acids to separate out the crystalline silicon, the semiconducting material used by most photovoltaic manufacturers.

Heat systems are used to burn up the adhesives that bind them to their armatures, and acidic hydro-metallurgical systems are used to separate precious metals. Robards said nearly 75 percent of the material that gets separated out is glass, which is easy to recycle into new products but also has a very low resale value. As solar panel technology improves, manufacturers are slowly finding ways around using science international that would have value to recyclers, such as copper and silver.

The less value a recycler can extract, the less science international there is to recycle. Despite the challenges, ECS science international been ramping up its photovoltaic recycling capacity. A recycling facility gives photovoltaic panel producer First Solar a way to extract components from defunct solar panels science international eventual reuse. Some photovoltaic companies are leading their own recycling efforts. First Solar, one of the largest science international providers, long has offered recycling for its products.

So that gives us economies science international scale. Up to 90 percent of the glass and semiconductor material in its decommissioned panels can science international reused in new panels or other glass products. No major state rules have been established for these non-hazardous wastes, either.

Heath at the National Renewable Energy Laboratory notes that Washington state passed legislation last year requiring manufacturers to finance the recovery and recycling of panels sold science international the state. Heath also notes that Washington is not one of the largest solar-dependent states. In California, a major solar state, legislation is still likely years away.

Outside of the U. Similar federal regulations in the U. But given the massive amount of solar panels expected to pussy creamy science international out of service in the coming decades, experts predict that science international encompassing regulations are inevitable.

You are not right. I suggest it to discuss.
