Novagg Seeks Backing to Develop Light Concrete for Offshore Wind

Sept. 24 (Bloomberg) — Novagg Ltd., a U.K. developer of
lightweight concrete for use in offshore wind foundations and
buildings, is looking for money to help bring its product to

The company is seeking 350,000 pounds ($574,000) to fund
development work prior to building a commercial-scale factory,
Bert Bingham, founder director, said in an interview in London.
Novagg is talking to two mineral-processing companies in England
to form a partnership to develop and build a commercial facility
either from scratch or using their existing plants.

Novagg combines waste glass from domestic, commercial or
industrial sources with industrial mineral wastes and turns it
into pellets. These are put through a kiln that makes them bloat
like popcorn to form spheres that are full of small air bubbles
and therefore light in weight. These can be mixed with cement to
make lightweight concrete.

“Lightweight concrete masts are ideal for offshore wind
towers as amongst other benefits they reduce deadweight and thus
foundation costs,” Bingham said. It can also be used in high-rise and low-rise buildings as a more sustainable option as the
energy input and carbon footprint of Novagg’s products is less
than competing options, he said.
