Syed MUAAZ, Cardiff University—Enhanced methane production from paper and woody waste

Global waste generation is expected to increase three-fold by the end of this century and as landfilling is presently the most common method of waste disposal, a significant proportion of this will be landfilled. Waste degrades slowly in landfills for centuries due to the recalcitrance of lignin-rich wastes (e.g. newspaper) and releases greenhouse gases into the geoenvironment. Hence, the current practice of landfilling is not sustainable. In this paper, we apply an enzymatic biodelignification technique to accelerate the breakdown of lignin in newspaper and wood, with the prospect of enhanced biogas recovery. The results suggest that enzymatic enhancement increases gas production in newspaper but does not have the same effect on wood. This talk will examine the nature of the problem highlighted above and discuss the key findings of our study. A better understanding of biodelignification systems could potentially help us decrease the time to stabilisation for landfills and result in significant environmental benefits.

Emily RADLEY, Swansea University—Paint through the ages

Come with me on a journey from early man and the ancient Egyptians, through some of the most magnificent masterpieces created by da Vinci, Rembrandt and van Gogh, to the industrial manufacture of paints throughout the 1800's, where paint and pigment synthesis truly came into its own and allowed what is now a multibillion euro industry to blossom. This amazing field has so many underlying impacts, from the colour on our walls and of our buildings, to identifying and protecting the art in our museums. Not to speak of the industrial developments of paint and coatings, which have allowed us to produce more finished products at greater speeds, we can even watch paint dry in less than 5 seconds!

Graham MUSTARD, University of Bath—Incineration by-products: Is carbonation a suitable method to enable reuse of hazardous waste ?

Waste management is a significant issue and will be exacerbated during the 21st century due to urbanisation. Waste incineration is an attractive management option; however hazardous gases are produced as a result. Therefore, incineration plants operate sophisticated flue gas treatment systems in order to remove the contaminants present within the flue gas prior to emission to the atmosphere. Air pollution control (APC) residues are one the solid by-products produced and are classified as hazardous waste. This talk will describe the key processes involved in modern incineration and their effects on hazardous by-products such as APC residues. The use of carbonation as a means of stabilizing APC residues allowing use as construction materials is then analysed. Three UK based incinerators have provided APC residue samples which have been analysed and the results are evaluated to provide context for the application of carbonation as a method to produce secondary building materials.

Pablo MART├ŹNEZ PANCORBO—Early-stage cancer imaging with novel nanoparticles

Cancer is one of the main challenges of the 21st century in developed countries. There are several techniques to identify and image it that have proved their capabilities for large cancer tissue. Unfortunately, when cancer spreads to large-scale structures, it can be too late to save a patient. There is an important need to find single cancer cells in the early-stages to improve rates of survival after applying a therapy. Nanoparticles functionalized with antibodies for cancer attachment have displayed the ability to image single cancer cells. This talk introduces a novel Au-SiO2-WO3 core-shell composite nanoparticle which displays strong cancer imaging capabilities via light scattering and potential for hyperthermia treatment. The more materials form the nanoparticle, the more useful properties can be used for a highly accurate cancer imaging and subsequent cancer therapy. These novel nanoparticles can broaden the horizons of biomedical material science in the upcoming decades.
