The Human race is
burying itself under a mountain of its own rubbish.
The UK alone produces some 400 million
tonnes of waste a year, a large proportion of which goes into
traditional "landfill" - literally dumped into large
holes in the land. But like many countries the UK is running out of
disposal space and the damage to the environment from landfill
sites is of increasing concern.
Now experts at Cardiff University's
Centre of Excellence in Waste Research, an initiative backed by the
Welsh Assembly Government, are drawing on world-leading expertise
from a range of disciplines in a race against time to find
solutions which will enable humanity to avoid an environmental
Among these solutions Engineers are
using the latest technology to update a time-honoured practice.
They are collecting data from large-scale experiments in
composting, taking and analysing constant readings of temperature,
gas flows, and gas composition - allowing them to achieve in 8
weeks a quality of compost that would take a year under traditional
methods - ensuring that millions of tonnes of domestic waste
becomes a valuable resource rather than a problem.
