Engineering the Soil Carbon Sink (ENGSCS)current researchCarbon Capture Gardens Carbon Capture GardensThe Carbon Capture Gardens are a demonstration site for soil carbon sink engineering, and at the same time they address wider ecosystem services through increased biodiversity. The Gardens are located at Newcastle Science Central, a 10 ha development partnership between Newcastle University the City of Newcastle, located in the centre of Newcastle upon Tyne. The Science Central site was formerly occupied by structures owned and operated by Scottish and Newcastle Breweries plc, which were demolished in 2007. A large proportion of the demolition waste (estimated to be approximately a million tonnes) was spread on site as a layer of ‘made ground’ or stockpiled. Potentially, this demolition waste could be used to capture around 20,000 tonnes of carbon from the atmosphere. The Carbon Capture Gardens are part of an experiment to see how this can be achieved.”

Relevant documents and outputs are available from downloads Scunthorpe and Consett steel worksWe are investigating the process by which in situ carbonation of industrial residues as a carbon capture process can be implemented at field scale, with specific focus on carbonation of basic oxygen slag. Our sites focus on at Yarborough inert waste landfill, Scunthorpe, and the former steelworks site near Consett (Figure 2). The project utilises both in situ study and laboratory research. Through a synthesis of all research findings, a model for the implementation of this form of carbon capture and storage (CCS) will be produced, including an allied assessment of the economic implications for its potential in the management of slag wastes.
Laboratory carbon determinationWe have developed facilities at Newcastle University to determine organic and inorganic carbon content of soils. We have developed a novel system of thermogravimetric - differential scanning calometry with evolved gas quadrupole mass spectrometry to simultaneously determine labile, refractory and recalcitrant compounds of organic carbon and inorganic carbon.

Acid digestion and volumetric measurement of evolved CO2 in a calcimeter is a robust method for determining inorganic carbon content of soils. (Reproducibility better than 0.6 % as CaCO3)
A Leco CS244 Carbon/Sulphur carbon analyser is routinely used for bulk organic carbon determination. |
