Diddordebau ymchwil

My research interests include methods for the identification of resources within landfills, routes to compute their potential value and how these can be exploited. This also forms part of my PhD research. I am also interested in the general concept of urban mining particularly at the molecular level.

Methodologies for the prediction and evaluation of potential resources within landfills

Within the United Kingdom (UK), recording of quantitative or qualitative data in respect of waste disposal did not occur until the implementation of regulations during the 1990s . For planners, commercial organisations, legislators and the researcher, the lack of data presents many problems.

Waste disposal to landfill has created a legacy of negative environmental issues due, for the most part, to reactive waste disposal strategy and practice. With the birth of the environment movement in the late 1960s/early 1970s, waste and its disposal methods began to be viewed as flawed strategies. Environmental uncertainties have subsequently become heightened not only because of the unknown chemical content of many landfills but also their proximity to coastal and wetland areas where erosion and flooding is becoming a major concern. A developing juxtaposition proposes existing landfills can now be conceptualised as material stores where the outcome can be considered as either waste-to-energy [WtE] or waste-to-materials [WtM]. To undertake either remediation or landfill mining (LFM) it will be necessary to ascertain both the hazard and resource potential contained within respective sites. Identification of the content of any landfill mass, whether in terms of value or hazard, is both complicated and necessary.

The scale of the problem should not be underestimated. The Environment Agency lists some 22,000 historic landfill sites for England. If we include Europe, this extends to some 500,000 sites with a waste volume lying between 50 - 80 billion m3. The contents of these sites range from inert materials to municipal solid waste (MSW) and many include an array of hazardous substances. Many were completed long before records were kept.
