Virtually no CO2 emissions
Climate Change Impact Assessment of our 'Cenin' Cement Replacements
Our ultra-low carbon cement replacement production technology developed by Celtic Cement employs the most environmentally friendly techniques to reduce carbon emissions. A report on the 'Climate Change Impact' of our cement products produced under the Cenin Cement brand has now been published.
Globally Portland Cement production is a major contributor to global warming and is a major source of the greenhouse gas carbon dioxide. For every tonne of portland cement produced almost one tonne of carbon dioxide is produced.

Our cement replacements reduce this emmission overhead to virtually zero by a combination of the innovative use of renewable energy and converting existing industrial by-products (waste) into a flexible, multi purpose cement replacement.

The chart above shows the amount of CO2 produced for each of our cement products compared to Portland Cement. Cenin 3 50/50 is a mixture of 50% replacement cement and 50% portland cement .
The assessment methodology follows the reporting principles and guidelines provided by the WBCSD Greenhouse Gas Protocol.
The scope of the independent assessment produced by 'Energy for Sustainable Development' includes: incoming delivery of raw materials; energy consumed during material processing and product manufacture; embodied emissions of materials and; product distribution.
The emissions associated with conventional Portland cement are 853 kilograms of CO2 per tonne of cement (British Cement Association).
"This study demonstrates that Cenin Cement have achieved substantial emissions reductions on this figure with their cement replacement products (an average across all products of 60% when compared to Portland cement) through a variety of measures."

The Chart above shows the amount of CO2 produced for each of our Cenin Cement products comparing the use of Renewable energy.
Cenin uses renewable energy in the production of its cement replacement products – specifically biogas and wind power. The chart above demonstrates what the total emissions for each product would be if Cenin used imported electricity, drawn from the UK grid, and natural gas. The chart also compares those emissions to the total emissions using only renewable energy. The UK electricity and natural gas emissions factors used in this analysis are provided by DEFRA.
By increasing the use of waste products as opposed to co-products (economically valuable by-products resulting from manufacturing processes) in the manufacture of cement replacement products, Canin can further reduce the emissions associated with their cement replacement products.
Energy Efficiency
Energy efficiency is an important component of a company's environmental strategy. Celtic Cement Technology has low input energy needs and can therefore utilise renewable energy sources such as biogas and wind energy in energy efficient Combined Heat and Power units.

November 2007
We presented a paper at the Global Slag Conference in Istanbul, Turkey 19 - 20 November. We demonstrated how Celtic Cement Technology can improve both the properties of slag cement and its environmental impact.
Patent Approval
August 2007
After fifteen years of detailed research and thorough testing the patent for our Celtic Cement Technology process was granted 29th August 2007, patent number GB2401104. The patent was applied for on 29th April 2003 and since that date we have been working on perfecting the process and applying it to a commercial scale enviromnent. Further testing on a diverse range of industrial waste materials has taken place in the meantime with fantastic cementatious properties being achieved.
