Resource or Project Abstract

Ireland has significant quantities of livestock; meat exportation is a vibrant sector of
the economy. Environmental management of animal wastes has therefore become an
important concern. On the other hand in the last decade, national and EU policy debate has
highlighted the need to investigate alternative energy: in particular energy for transport.

This study investigates the quantities of animal wastes produced in Ireland and their
potential treatment using Anaerobic Digestion technologies. In 2005 Ireland had over 8
millions animals (cattle and pigs) and the annual slaughter accounted for over 4.2 million of
these creatures. These animals have been responsible for the production of about 86 million
tons of excreta per annum, whereas the abattoir industry produced more than 750,000 tons
of carcasses per annum.

These wastes can be employed as feedstock in Anaerobic Digestion processes and
provide biogas which can be upgraded to methane and used as transport fuel. From 1 ton of
cattle slurry it is possible to produce about 21 Nm3 of biogas whereas from 1 ton of pig
slurry it is possible to produce about 24 Nm3 of biogas. Carcasses have a higher energy
potential with a specific biogas yield of about 168 Nm3 of biogas per ton of waste.

A Decision Support Software for assessment of biogas production from animal
wastes has been produced. It contains:
1. A geographical database of livestock and abattoir throughout Ireland;
2. An Energy potential model to estimate the biogas production from a specific
number of animals (input of the model);
3. An economic model to evaluate costs and incomes associated to Biogas plants;
4. A location model to identify valuable areas for biogas projects development.

slurry it is possible to produce about 24 Nm3 of biogas. Carcasses have a higher energy
