Lithium’s (Li) value has grown exponentially since the development of Li-ion batteries. It is usually accessed in one of two ways: hard rock mineral mining or extraction from mineral-rich brines. Both methods are expensive and require a rich source of Li. This paper examines the potential of agro-mining as an environmentally friendly, economically...
The earliest evidence of humans mining for metals dates back 40’000 years ago to the late Pleistocene period. Since then the extraction of metals from the earth has been an imperative for the advancement and prosperity of human civilization. We are not the only ones who have been extracting metals from the earth, plants have been doing this for the...
Conventional mining operations require a high-grade ore deposit, to justify the massive capital investment required to start a mining project. These deposits are rarely found today however demand for the metals they contain is still rising. Therefore, mining companies are currently investigating cost-effective methods to meet this demand. A seconda...

Tributyltin (TBT) is a synthetic organotin compound and is recognised as the most toxic chemical ever knowingly introduced into the marine environment. Organotins have a wide range of application with an estimated global production of 50,000 tons per year therefore impacts from TBT can be seen or anticipated in many environments including protected...
Phytomining, a concept first introduced in the 1970’s involves the use of plants in the mining process. Certain species of plants have the ability to take up large amounts of metals into their tissue without harming the plant. It can be defined as the production of a metal by growing a high biomass plant which accumulates high concentrations of a t...
The extensive use of chemical fertilizers in modern agricultural practice is an expensive, wasteful and environmentally damaging approach. As such, there is a drive towards more effective and environmentally friendly alternatives. One potential technology is the use of biological fertilizer instead of/ combined with reduced levels of chemical ferti...
The South East of Ireland (County Carlow) contains a deposit of the valuable lithium-bearing mineral spodumene (LiAl(SiO 3) 2). This resource has recently attracted interest and abstractive mining in the area is a possibility for the future. The open cast mining of this resource could represent a potential hazard in the form of metalliferous pollut...
Abstract Tributyltin (TBT) is the most toxic chemical ever knowingly introduced into the marine environment, exerting lethal effects on a wide variety of marine organisms. Due to the impact of TBT a necessity exists for the screening of TBT resistant and degrading bacteria for the treatment of contaminated marine sediment. Therefore the approach ta...

Tributyltin (TBT) is an organotin compound that has been used as a biocide in marine antifouling paints to restrict the attachment of gastropods to hull surfaces. Widespread use of this anthropogenic pesticide has led to its release into aquatic environments, as a result, a global ban on the use of TBT has been enforced since January 2008. TBT mole...
2,4-Dichlorophenoxyacetic acid is a selective systemic herbicide for the control of broad-leaved weeds, which is widely used throughout the world. The persistence of its residues and its potential to migrate in the soil make it necessary to reduce its concentrations in contaminated soil and groundwater. The nature of this compound makes it particul...
Constructed wetlands are man-made systems that can be designed for the treatment of polluted water. One of the main mechanisms of detoxification is considered to be the high microbial activity in the nutrient and oxygen rich environment surrounding wetland plant roots. A simple small-scale wetland model system was developed to evaluate the ability...

The project will assess the ability of a range of microbial species to degrade TBT into its less toxic species monobutyltin (MBT) and dibutyltin (DBT) and further determine the optimum conditions for reduction of TBT in marine sediments. These bacteria strains will be identified based on biochemical characteristics and 16rRNA sequence analysis. This study will also aim to investigate and asses the ability of barley and salt marsh plants (Halimione portulacoides, S. maritima) to degrade TBT in sediment and soil. In addition a novel approach will be taken to inoculate the rhizosphere with bacteria previously isolated during the course of the project to enhance the phytoremediation capacity of the barley and salt marsh plants. The current EQS of TBT is creating problems in laboratories when trying to quantify TBT and its less toxic species therefore an investigation in to a method for detection of low levels of organotins will take place taken a green analytical chemistry approach.
Currently, over one million cubic meters of landfill leachate (LFL) is collected and transported to urban wastewater treatment facilities annually in Ireland. The generation of heavily polluted leachate is one of the major drawbacks associated with old and new municipal solid waste landfills in Ireland. This leachate constitutes an expensive by-product which requires storage, transport and normally expensive treatments.
Many methods are being used to treat LFL, most of which are adapted from wastewater treatment methods. These methods usually involve a combination of biological and physiochemical treatments and are somewhat effective in the treatment of LFL. It can be difficult to obtain satisfactory results with just one method. These treatment options are generally expensive, time-consuming and often inadequate.
This project deals with the treatment of LFL through microbial biodegradation and physical adsorption of leachate constituents. It seeks to develop a cost-effective treatment option for LFL based on the combining treatments, which will be suitable for implementation on-site in landfills in Ireland. This research will have the potential to impact on how LFL is treated and the principal driver for the work is to design an on-site, cost-effective suitable treatment option for the waste management sector.
