Wharf’s green future firming up

Carbon-cutting concrete is helping re-activate an east London wharf, acquired by the Port of London Authority (PLA) to grow the use of the tidal Thames for freight.

Developed by Australian company Wagners, Earth Friendly Concrete (EFC®) is paving the way for building materials to be delivered by barge to Plaistow Wharf in Silvertown, for use in construction projects, in and around London.

Along with the adjacent Peruvian and Royal Primrose wharves, the site on the doorstep of London City Airport, has been acquired by the PLA, as part of its investment strategy to boost the river’s economy.

Keltbray, the PLA’s tenant at Plaistow Wharf, is leading the installation of EFC on site, in partnership with Capital Concrete, as well as the on the neighbouring Royal Primrose Wharf.

The product typically halves levels of embodied carbon, when compared with traditional alternatives.

On site to review progress (23 February), Steven Clapperton, the PLA’s director of sustainable marine operations, said: “It is exciting to see the latest green technology involved in re-establishing these wharves, which were so integral to London’s development as a major world port.

“Greater, sustainable use of the river for trade is an essential precursor to the capital delivering Net Zero.

“It’s an aim at the heart of our investment strategy, which is now delivering tangible benefits for the growing number of businesses involved in conveying goods and materials by barge, up and down the river.”

The energy savings EFC delivers are the result of an innovative binding system, utilising waste by-products, for example blast furnace slag from the production of iron.

Its other advantages include better durability, reduced shrinkage and increased fire resistance.

Following rigorous laboratory testing to meet strict industry standards, it has already been used in building projects across London.

Due for completion this spring, the marine works, covering 0.4 acres across the two wharves, to create safe areas for the loading and unloading of materials, are currently at their half-way stage.

Tim Lohmann, Keltbray’s director of strategic engineering, said: “Working alongside the PLA, we could not be more proud to be playing our part in the renaissance of the Thames as an eco-friendly conduit for freight.”
