An e-waste opportunity? You might have to get your hands a little dirty, but the business of preventing electronics from stacking up in landfills and poisoning the environment promises to grow rapidly within the next five years. According to ABI research, e-waste recycling will rise from the $5.7 billion market it is today to $15 billion by 2015. Most of that value will be generated by plucking precious metals and materials from discarded electronics. Naturally, firms that perfect that process will be biggest winners.
