High viz
Severn Trent has started operations at
its latest green gas plant in Roundhill
near Stourbridge, West Midlands.
The new facility uses anaerobic
digestion to turn food waste that is
unfit for human use into clean power.
The Roundhill site will be able
to recycle almost 50,000 tonnes of
packaged and unpackaged food waste
each year and will produce enough
renewable gas to heat 2,700 homes
and enough renewable electricity to
power 1,700 homes.
The gas is made suitable for
domestic use with a process that
involves complex engineering tech-
niques. First it is "washed" at high
pressure, it is then "squashed", or
