You are correct! That Attero Recycling company in India I have posted about before. (It is speculative, but putting pieces of the puzzle together makes it appear they will work with each other in the near future)
Electronic waste recycling company Attero Recycling is at an advanced stage of discussions with a number of global investors for fresh capital to fund its overseas expansion plans. Texas-based Waste Management is a leading contender to invest in Attero which expects to raise up to Rs 208 crore in this round of funding, according to a person involved in the negotiations. http://articles.economictimes.indiatimes.com/2013-07-04/news/40371872_1_attero-recycling-waste-management-electronic-waste
That was released in July and they still haven't seen the investment. Maybe EWSI quickly came on to the radar and are being pursued by these big investors??? Time will tell! But 1 thing is for sure....Waste Management is looking to invest or partner...not necessarily buy out everything.
