SIGMAROC ANNUAL REPORT 2023 STRATEGIC REPORT
Greenbloc and environmental sustainability
CCP Greenbloc as standard; Through 2023 Greenbloc technology has made significant strides in sustainable development across the business, offering up to 50% carbon reduction on all standard blocks produced at CCP Building Products. This has saved over 6,000 tonnes of CO2 since its introduction and has been offered at no additional cost to the customer. CCP completed its expanded new ranges by introducing an additional premium range product, which sits between its standard 50% reduction product and ultra cement-free, and provides up to a 70% carbon reduction at a competitive price.
Poundfield Cement-free; Further Greenbloc cement-free development at Poundfield introduced a necessary flexible solution, enabling daily production and the ability to turn cement-free concrete on-and-off for environmentally significant bespoke projects. These include the UK Environmental Agency’s Canvey Island Sea Defence and Jimmy’s Farm Polar Bear Relocation projects, both of which achieved over 80% reduction in the carbon embodiment of the concrete products. As a result of these initiatives, Poundfield has become one of the leading UK producers of cement-free pre-cast concrete, producing more wet-
cast cement-free concrete per day than any other precast company, and underscoring the industry’s shift towards more sustainable practices. The resulting media focus has brought more cement-free projects to the business for 2024.
Greenbloc carbon-negative; A leap in innovation was gained through the production of a carbon-negative-cement-free concrete block, which boasted a 115% carbon reduction and was created using Greenbloc cement-free technology, combined with carbon-negative aggregate produced from waste materials and captured carbon. The block showed all the same characteristics and performance as standard equivalent cement-based blocks and is expected to become part of an extended future range with the introduction of Mevo at CCP in 2024.
Marshalls collaborative Greenbloc – MTech; SigmaRoc has produced an in-house cement-free-carbon-negative concrete with patentable opportunities, in collaboration with Marshalls. The concrete combines carbon-negative materials with an in-house developed cement-free binder which incorporates upcycled waste lime kiln dust from Nordkalk. The patent application will be submitted in 2024 with expected opportunities for use in 2025.
