Potential To Increase Indigenous Biodiesel Production To Help Meet 2020 Targets – An Eu Perspective With A Focus On Ireland, Fionnuala Murphy
Potential To Increase Indigenous Biodiesel Production To Help Meet 2020 Targets – An Eu Perspective With A Focus On Ireland, Fionnuala Murphy

The biofuels penetration rate target in Ireland for 2013 is 6% by volume. In 2012 the fuel blend reached 3%, with approximately 70 million litres of biodiesel and 56 million litres of ethanol blended with diesel and gasoline respectively. For January and February 2013, the blend rate had only reached 2.7%. The target of 10% by 2020 remains which equates to approximately 420 million litres. Achieving the biofuels target would require 345 ktoe by 2020 (14,400 TJ). Utilising the indigenous biofuels outlined in this paper leaves a shortfall of approximately 12,000 TJ or 350 million litres (achieving 17% of the …

This paper applies multiple Multi-Criteria Decision Management (MCDM) methods as a mechanism for identifying international markets for a producing nation’s food production. The specific application presented in this paper is for export markets of Iranian Pistachios; however, the model could be applicable across multiple food products and nations. Quantitative and qualitative criteria for market assessment were identified via a literature review. These include: 1) Regulation criterion, 2) Cultural criterion, 3) Transportation distance criterion, 4) Economy criterion, 5) Market potential criterion, 6) Politics criterion, 7) Revealed Comparative Advantage (RCA). Shannon’s Entropy method was applied to weight criteria based upon the context-dependent …

Statistically, the actual loading conditions for railway tracks are rather dynamic and transient. The dynamic loadings due to train and track interactions redistribute from the rails to the rail pad, from the rail pad to the railway sleeper, and from the railway sleeper to the underlying ground. Commonly, railway sleeper in track systems is modeled as a beam on elastic foundation. This study makes use of a calibrated finite element model of railway sleepers in a track system, in order to investigate the resonant frequencies and associated mode shapes of railway components in interspersed track systems. The numerical model takes …

Statistical Process Control (SPC) is a powerful collection of problem solving tools and the most sophisticated useful method in achieving process stability and improving the process capability through the reduction of variability. In the manufacturing process, every product doesn’t meet the desired range of quality consistently with the customer specification. This inconsistency occurs due to several sources of variations such as machines, operators, materials etc. The Ultimate target of control chart is to monitor the variations, and subsequently control the process. On account of applying SPC methods, this study deals with the control and improvement of the quality of bolt …

The demand for wood for energy production in Ireland is predicted to double from 1.5 million m3 over bark (OB) in 2011 to 3 million m3 OB by 2020. There is a large potential for additional biomass recovery for energetic purposes from both thinning forest stands and by harvesting of tops and branches, and stumps. This study builds on research within the wood-for-energy concept in Ireland by analysing the energy requirements and greenhouse gas emissions associated with thinning, residue bundling and stump removal for energy purposes. To date there have been no studies on harvesting of residues and stumps in …
