Wind turbine blades are generally large and
non-recyclable and at the end of their service end up in huge
landfills that have started attracting environmentalists'
attention.
Rival Vestas in May unveiled technology enabling wind turbine
blades to be fully recycled, but Siemens Gamesa claimed in its
statement on Tuesday that it was the first company to produce
recyclable blades.
Wind turbine blades are made with resins that tie together their
different materials. Siemens Gamesa, which produces blades up to
125 metres long, uses a resin with a special chemical structure
that allows it to separate the other materials, which can then
be reused, it said.
The unit of Siemens Energy said it has already reached
agreements to sell recyclable blades to three utilities
Germany's RWE, France's EDF and Britain's Western Power
Distribution.
