Resource or Project Abstract

This report details the work carried out during the Smart Plant project, funding code 2005-AIC-MS- 43-M4. As part of this research, an autonomous platform for monitoring greenhouse gases (methane (CH4), carbon dioxide (CO2)) has been developed, prototyped and field validated. The modular design employed means that the platform can be readily adapted for a variety of applications involving these and other target gases such as hydrogen sulfide (H2S), ammonia (NH3) and carbon monoxide (CO) and the authors are in the process of completing several short demonstrator projects to illustrate the potential of the platform for some of these applications. The field validation for the greenhouse gas monitoring platform was carried out at two landfill sites in Ireland. The unit was used to monitor the concentration of CO2 and CH4 gas at perimeter borehole wells. The final prototype was deployed for over 4 months and successfully extracted samples from the assigned perimeter borehole well headspace, measured them and sent the data to a database via GSM communications. The data were represented via an updating graph in a web interface. Sampling was carried out twice per day, giving a 60-fold increase on current monitoring. The authors believe that a unit which is capable of such monitoring has been developed and validated. This unit provides a powerful tool for effective management of landfill site gases. The effectiveness of this unit has been recognised by the site management team at the long-term ix deployment trial site, and the data gathered have been used to improve their day to day operations and gas management system on-site. The CO2 levels can be accessed remotely via the web link:

Lineage information about this project or dataset
Landfill is defined as a waste disposal site for the deposit of the waste onto or into land. Accordingly, landfill gas is defined as all the gases generated from the landfill waste (EU Council Directive, 1999/ 31/EC). It is generated by the decomposition of biodegradable waste. Additionally, a liquid known as leachate is also generated. Landfill gas is comprised of approximately 100 different components, though the main components are CO2 and CH4 gas (~ 99 % v/v) (Bridges et Waste can starts to generate landfill gas about 3 - 6 months after being deposited depending on the amount of decomposition undergone by the waste before landfilling (Office of Environmental Enforcement, 2010, pers. comm.), and this conversion takes place over five phases. Initially, the environment is aerobic and mainly CO2 gas is produced (Aitchison, 1996).
