Poisons leached out

Poisonous water leaking away from rubbish dumps could be made safe enough to mix into rivers and streams through a new project in mining and mineral engineering. The 80,000 study also aims to reduce the time taken for landfill sites to stabilise by speeding up the generation of methane gas.

Bill Birch is leading the research, which involves passing the contaminated water through tanks filled with plants. The project grant comes from a 4m fund set up by waste services company Biffa - using money collected from taxes on waste dumped in landfill.
