Norcal's Pier 96
Norcal Waste Systems handles most of San Francisco's household waste. Driven by SFs regulative pressure the company invests in new techs:
Quote The Economist:
"In another cathedral-like warehouse by municipal Pier 96, Norcal sorts the stuff local residents put into their recycling bins. An impossibly complicated network of conveyor belts, chutes and tubes whizzes the trash this way and that. Machines separate out different materials, in much the same way as Mrs Hiyale and her fellow rag-pickers do back in Mumbai. A magnet lifts up any iron and steel. A gadget called an “eddy-current separator” causes other metals, such as aluminium and copper, to jump, literally, off the line into different bins. A series of whirling discs arranged into a steep slope carries the lighter goods—mainly paper—upwards but allows heavier ones to fall. Workers pick off phone books, glass and plastic bottles."
