  • Design and commissioning of a multi-mode prototype for thermochemical conversion of human faeces 
    Jurado Pontes, Nelia; Somorin, Tosin; Kolios, Athanasios J.; Wagland, Stuart; Patchigolla, Kumar; Fidalgo, Beatriz; Parker, Alison; McAdam, Ewan; Williams, Leon; Tyrrel, Sean (Elsevier, 2018-03-23)
    This article describes the design and commissioning of a micro-combustor for energy recovery from human faeces, which can operate both in updraft and downdraft modes. Energy recovery from faecal matter via thermochemical ...
  • Faecal-wood biomass co-combustion and ash composition analysis 
    Somorin, Tosin; Kolios, Athanasios J.; Parker, Alison; McAdam, Ewan J.; Williams, Leon; Tyrrel, Sean (Elsevier, 2017-05-16)
    Fuel blending is a widely used approach in biomass combustion, particularly for feedstocks with low calorific value and high moisture content. In on-site sanitation technologies, fuel blending is proposed as a pre-treatment ...
  • Faeces - Urine separation via settling and displacement: Prototype tests for a novel non-sewered sanitation system 
    Hennigs, Jan; Ravndal, Kristin T.; Parker, Alison; Collins, Matt; Jiang, Ying; Kolios, Athanasios J.; McAdam, Ewan; Williams, Leon; Tyrrel, Sean F. (Elsevier, 2020-08-23)
    The development of novel, non-sewered sanitation systems like the Nano Membrane Toilet requires thorough investigation of processes that may seem well-understood. For example, unlike the settling of primary sludge, the ...
  • Failure mode and effects analysis using a fuzzy-TOPSIS method: a case study of subsea control module 
    Kolios, Athanasios J.; Umofia, Anietie; Shafiee, Mahmood (Inderscience, 2017-07-03)
    Failure mode and effects analysis (FMEA) is one of the most common reliability engineering techniques used for identifying, evaluating and mitigating the engineering risks. In this paper, the potential failure modes of a ...
  • Field testing of a prototype mechanical dry toilet flush 
    Hennigs, Jan; Ravndal, Kristin T.; Blose, Thubelihle; Toolaram, Anju; Sindall, Rebecca C.; Barrington, Dani J.; Collins, Matt; Engineer, Bhavin; Kolios, Athanasios J.; McAdam, Ewan; Parker, Alison; Williams, Leon; Tyrrel, Sean (Elsevier, 2019-02-17)
    A prototype of a non-fluid based mechanical toilet flush was tested in a semi-public, institutional setting and in selected peri-urban households in eThekwini municipality, Republic of South Africa. The mechanism's ...
  • Life-cycle assessment of self-generated electricity in Nigeria and Jatropha biodiesel as an alternative power fuel 
    Somorin, Tosin Onabanjo; Di Lorenzo, Giuseppina; Kolios, Athanasios J. (Elsevier, 2017-06-21)
    Insufficient available energy has limited the economic growth of Nigeria. The country suffers from frequent power outages, and inconvenient black–outs while residents and industries are forced to depend on self-generated ...
  • Reanalysis of offshore T-joint fatigue life predictions based on a complete weld profile model 
    Lozano-Minguez, Estívaliz; Brennan, Feargal Peter; Kolios, Athanasios J. (Elsevier, 2014-06-20)
    A comparison between the fatigue life predictions obtained by the stress concentration factors (SCFs) of 3D solid finite element (FE) models considering the weldment and the existing SCF parametric equations for tubular ...
  • Techno-economic optimisation of offshore wind farms based on life cycle cost analysis on the UK 
    Mytilinou, Varvara; Kolios, Athanasios J. (Elsevier, 2018-08-03)
    In order to reduce the cost of energy per MWh in wind energy sector and support investment decisions, an optimisation methodology is developed and applied on Round 3 offshore zones, which are specific sites released by the ...
  • Thermodynamic analysis of a gamma type Stirling engine in an energy recovery system 
    Sowale, Ayodeji; Kolios, Athanasios J.; Fidalgo, Beatriz; Somorin, Tosin; Parker, Alison; Williams, Leon; Collins, Matt; McAdam, Ewan; Tyrrel, Sean (Elsevier, 2018-04-01)
    The demand for better hygiene has increased the need for developing more effective sanitation systems and facilities for the safe disposal of human urine and faeces. Non-Sewered Sanitary systems are considered to be one ...
