Sustainability Assessment of Waste Management
Waste management is a long standing topic of research in the School. Over the last few years the
emphasis has moved away from landfill technologies to the assessment of the environmental and
sustainability aspects of waste management options.
KTP Grundon Waste Management
Waste collection at Heathrow Airport
Waste collection at Heathrow Airport
This project started in mid-2011 and will develop a bespoke Carbon Footprinting IT system for Grundon
combining the School’s expertise in waste management, life cycle analysis and applied IT software
development. This will assess the range of waste processing and disposal options offered by Grundon
to allow the company and customers to make informed decisions about the Carbon Footprint of wastes
and to reduce emissions.

Sustainability of Waste Management in Nigeria
This project was funded by the Petroleum Development Fund of Nigeria and has recently seen a
successful PhD defence (Batagarawa, 2012). It involved analysis of the weightings that stakeholders in
waste management (including regulators, formal and informal sectors) put on aspects of Sustainable
Development via the Analytical Hierarchy Process and then using this data to develop an index for the
sustainability of waste management options.

Sediment Dynamics in Estuaries
Dr Steve Mitchell, Dr Isaac Boatang
Steve Mitchell is active in research trying to quantify the flux of fine sediments in macro-tidal estuaries.
UK ports are characterised by high tidal range and seasonal inputs of fresh water flow from rivers. In
many cases natural estuaries have been canalised following the need to provide farmland on the one
hand and navigable channels on the other. The Trent-Ouse system is one example, but maintenance
dredging for navigation is also carried out in the Thames and the Severn.
The effect of the high tidal range is to force fine sediment and saline water inland, successively on each
tide. The effect is more noticeable on spring tides. The fresh water flow from the river acts to counter
this effect, so for high river flows during the early part of the year (see below example for the Thames),
both the salinity (top line) and the suspended sediment concentration (bottom line) are lower than they
are later in the year.
