The utilisation of anaerobic digestion to produce biogas as an energy source is a mature technology in many European countries but is yet to be developed in Ireland. In 2009, the EU issued the Renewable Energy Source Directive 2009/28/EC which requires a 20% share of renewable energy sources...

This paper presents modelling based on 340days of operation of a small pilot-scale, 2-stage completely-mixed digester, loaded gradually up to an organic loading rate of 2.5kgm−3d−1. The reactor suffered mechanical failure in the agitation system due to high solids content in the digester....

Grassland biomass is likely to be harvested and stored as silage to ensure a predictable quality and a constant supply of feedstock to an anaerobic digestion facility. Grass (Phleum pratense L. var. Erecta) was ensiled following the application of one of six contrasting additive treatments or a...
