Green-washing Solar Panel Manufacture
May 11th, 2010

I tend to be skeptical when it comes to just how “green” the Chinese revolution is in the renewable energy sector. Hundreds of makers of solar photovoltaic (PV) cells and attendant equipment manufacturers crowded the hallowed halls of the Shangahi International Exhibition center. The SNEC 4th International Photovoltaic Power Generation Conference & Exhibition ran from May 5 -7, with conference proceedings from May 7 – 9.
One of the more revealing exhibits was that of CRS Reprocessing Services, based in Louisville Kentucky. Since 2003 CRS has been cleaning up after PV makers in America, Europe and Japan, and is just breaking into China. The company builds the equipment and implements the processes needed to recycle chemical slurry for re-use. The company claims a 98% re-capture rate. The slurry is a combination of liquid chemicals and a fine dust that result from cutting silicon into the thin wafers that serve as the base for photovoltaic cells. Prospects for growth for the company in the China market are huge, as Chinese PV makers have until a recent change in government policy been pouring a poisonous slurry into plastic bags they pile up in the back of their factory compounds.
Deborah Reese, Director of Marketing, told us of one potential Chinese customer who had so much of the slurry built up “you could actually see the dump from satellite photos, if you knew where to look.”
Of course, national government promotion of a sector looking to grow into a trillion dollar marketplace would prefer we look elsewhere.
