    Waste recovery for metal manufacturing

    There are several challenges faced by the metal manufacturing industry. Firstly, there is a drive to recover as much metal credit as possible before disposal of by-products as wastes. Secondly, there is a requirement to minimise waste generation or alternatively minimise the costs of managing the disposal of any hazardous waste material generated during the manufacturing process. Finally, keeping the company competitive by generating value or by reducing costs in the manufacturing process. Any solutions that can overcome these challenges must be considered. Tetronics can assist with a range of metal manufacturing waste challenges, including:

    Metal Stabilization

    In-situ geochemical fixation using a chemical reductant such as Remotox (calcium polysulfide) converts the soluble toxic metals into insoluble non-toxic compounds. Remotox has proven to be effective under a wide range of conditions. It is considered more stable and persistent than other reductants in subsurface environments, and is relatively safe to handle in the field and easy to apply.

  • XRF analysis for environmental applications

    Niton analysers are versatile environmental testing instruments that provide valuable assistance in portable soil testing applications such as brownfield site investigation. With the ability to analyse a wide range of materials, our instruments provide lab-quality soil/sediment chemistry in seconds. Lead, arsenic, cadmium, chromium, and other toxic metals contaminate sites of former industrial and agricultural activity around the world. Whatever the reasons for these occurrences, these pollutants cannot be ignored – particularly as environmental consciousness and regulatory initiatives grow.

    Mercury monitoring for on-site remediation

    Fugitive emissions can be a health concern during removal and disposal of mercury-contaminated material at remediation sites. Thus, remediation projects either indoors or outdoors often require on-site, real-time mercury air monitoring with a Tekran 2537. This assures permitted levels are not exceeded during waste processing and human exposure levels are below government regulated toxicity thresholds. Often multiple sites must be monitored continuously. The Tekran 1115 Multi-Port Sampler is the ideal tool for multiplexing the Tekran 2537 for real-time continuous on-site monitoring of mercury fugitive emissions. Please contact us for more information on mercury remediation monitoring.
