Carbon price blockbuster launched at
Ecobuild
New range of hemp blocks that combine carbon neutral properties with conventional block performance have been launched at Ecobuild 2008 by Lime Technology.
The Hemcrete blocks, available in structural or non structural form, are factory produced and the same size as conventional building blocks (215mm x 440mm) Unlike conventional blocks, however, Hemcrete blocks are zero carbon rated

To minimise cement usage and to facilitate future recycling, hydraulic lime mortar from Lime Technology was specified by architects Fielden Clegg Bradley .
Hemcrete - a bio-composite material that blends hemp with a special lime based binder to create a zero, or less than zero, carbon rating - has been available for several years as a cast or spray applied on site application.
By creating a factory produced block, Lime Technology is offering its customers the sustainability benefits of Hemcrete with the flexibility of having easy to lay, like-for-like blocks.
Hemp is a natural material that locks in carbon as it grows.
Through its carefully measured use in the Hemcrete block manufacturing process, the structural blocks have a zero carbon footprint.
This makes them the perfect sustainable masonry solution as part of a zero carbon house.
The non-structural blocks have superior thermal performance and a negative carbon footprint.
This means they can be used as a method of offsetting carbon from other areas of a building's construction.
Hemcrete structural blocks also offer better thermal insulation than conventional dense blocks.
In addition, they have the ability to absorb and hold heat (thermal mass) during sunny periods when heat is not needed for internal living or work spaces.
Instead, the heat is released when it is required, such as during overcast periods or at night, to provide substantial energy and cost savings.
Lime Technology's Managing Director, Ian Pritchett, said: "Hemcrete is a proven method of substantially reducing a building's carbon footprint, in terms of its construction and ongoing use".
""By offering our customers Hemcrete in block form, we are adding flexibility to the material.
This will appeal to today's mass construction market where materials, such as hemp, have previously been considered too niche to be commercially viable.
"Hemcrete blocks prove that traditional raw materials, such as hemp and lime, can offer one of the best value materials for low impact, sustainable construction.".
