Research interests

Composting process optimisation A series of projects are running in this area which cover process aspects such as: sanitisation, stabilisation, process design and rate of biodegradation.

 Bioaerosol generation, dispersion and control The mechanisms which govern the growth of microorganisms such as Aspergillus fumigatus during waste treatment are being studied. This study extends to site work to determine conditions which promote generation and dispersion and also systems which can be used, such as biofilters, to restrict the rate of release.

The relationship between laboratory compost systems and performance at full scale Laboratory composters are being run in parallel with full scale systems to determine how effective the laboratory scale systems are for predicting performance at full scale.

Determining compost stability The specific oxygen uptake rate (SOUR) method for determining stability, which was developed in Leeds, is being used to determine process performance with a range of full scale composting systems. SOUR is also undergoing comparative trials against other stability testing methods.

The effect of autoclaving on composting and anaerobic digestion of wastes A programme that is studying the impact of different autoclave conditions (from 130 - 200 Deg.C) on the subsequent composting and digestion of wastes. The work is being carried-out at laboratory and pilot scale.

Waste management in developing countries The selection of appropriate waste management systems and funding mechanisms linked to carbon credit trading.
