Human activity leads to the generation of waste which if not managed correctly can contaminate environments. The treatment of generated waste (as well as contaminated soil, sediment and water environments) can involve biological, chemical and/or physical techniques usually at the science/engineering interface. Our applied research focuses on developing tools to support treatability testing of remediation technologies with an emphasis on bioremediation, as well as, applying physical science and civil engineering based technological developments (with both internal and external collaborators) for real-time, rapid and/or non-intrusive brownfield site investigation techniques. Research in this area is being extended to include the evaluation and optimisation of organic waste treatment output materials for reuse in agricultural and landscape/regeneration sectors.
