I posted the same link in this thread already, in another context, but it's relevant enough: http://www.teslamotors.com/blog/mythbusters-part-3-recycling... "The result from this process is that we are able to recycle about 60% of the ESS materials and reuse a further 10% (by weight). We currently plan to landfill only the benign fluff, which comprises about 25% of the ESS, but we expect to nearly eliminate this in the future when our volumes get higher and we can justify the effort required to separate and reuse the plastic."
