Researcher/PhD Student




Abdul-Sattar Nizami is a PhD student (2008-2011) with Dr. Jerry D Murphy in a project “GreenGrass: Developing grass for sustainable renewable energy and value added products” funded by Department of Agriculture, Fisheries and Food under the National Development Plan. The collaborating institutions are Teagasc Grange, Queen’s University Belfast (QUB). Mr. Nizami holds his master degree in Environmental Engineering from Chalmers University of Technology, Sweden and B.Sc (Hons) degree in Environmental Sciences from the Punjab University, Pakistan.



Project Brief:


The initial aims of the project were to:

  • Undertake a literature review of all aspects of the grass biomethane system

  • Identify appropriate anaerobic digestion technologies suitable for grass/grass silage digestion;


A number of reactor systems were designed, fabricated and are now situated in the Biofuels Laboratory. These systems include for:

  • A Sequential Batch Leach-Bed Reactor coupled with Upflow Anaerobic Sludge Blanket (UASB).

  • A Continuous Stirred Tank Reactor (CSTR).



The objectives of the project are:

  • Determine the potential biogas/CH4 production per unit of energy crop;

  • Compare performance data for differing digester designs.
