Some recyclable materials such as paper, glass, metals, plastics, fabrics, batteries, and electronic waste are recycled into new products to reduce consumption of additional environmentally harmful raw materials. Companies such as Waste Management (WM), Waste Connections (WCN), and Republic Services (RSG) have a large presence in waste recycling. Waste Management (WM) is part of the PowerShares S&P 500 Low Volatility ETF (SPLV) with 1.06% holding.
