    Shredders and crushers for LCD monitor recycling

    According to initial estimates, in Germany about three million LCD monitors will be recycled in the year 2016. However, they often still have backlighting containing mercury and therefore have to be classified as “hazardous waste” in accordance with the German General Administrative Regulation (AVV) and registered in compliance with the German Electrical and Electronic Equipment Act (Elektro G) under category 3. Whereby special conditions must ensure that no risk arises from the mercury for the environment or for humans. However, because of a lack of suitable automated procedures for the recycling of LCD monitors, it was to date only possible to dissemble the appliances laboriously by hand, with the ensuing health dangers for the workers.

    Mercury monitoring for isotopic abundance by the ICP-MS

    Studies of real-world ecosystems are very complex. Mercury species inter-conversion as well as mercury deposition and evasion are constantly occurring. One technique to help sort out the processes is to trace reactions using natural Hg isotopes. Either by enriching a system with a particular isotope or determination of isotopic ratios as a technique of source identification, isotopes are a powerful tool for investigation. The Tekran 2600 Total Mercury and Tekran 2700 Methyl Mercury systems are designed to couple to an ICP-MS for mercury quantification by CVAFS and isotopic abundance by the ICP-MS.

    Mercury monitoring for measuring mercury content in hair

    Measurement of mercury content in hair is a convenient technique to estimate dietary exposure without having to handle tissues or bodily fluids. As the mercury present in hair is comprised of different mercury species, full speciation of the compounds is needed for complete understanding. Environment Canada published a technique where treating a basic digestion with Cd2+ in the presence of cysteine allowed analysis of inorganic mercury and total mercury using a Tekran 2600 System. Methyl mercury was then calculated by difference. Tekran has over 18 application notes available for Tekran 2600 users.

    Continuous emissions monitoring for mercury monitoring

    Waste incinerators, cement plants and power plants need good and reliable measurements of total gaseous mercury. The measurement of total gaseous mercury is a challenge due to chemical reactions and contamination. The installed systems will often require a lot of maintanence still not giving reliable results.

    Hazardous waste treatment solutions for oil and gas industry

    There are a wide amount of applications for our VacuDry® process within the oil and gas industry. A large variety of wastes and by-products that are generated in the oil & gas production chain can be treated effectively and sustainably. In past decades, numerous thermal desorption processes have been implemented worldwide, using a variety of heating chamber designs to separate hydrocarbons from the mineral solids. Such standard TDUs work under atmospheric pressure which can lead to safety risks, high energy consumption, larger emissions and limited flexibility regarding altering feed materials. Due to its unique design, the complications outlined above are avoided throughout the VacuDry® process. When it comes to treating standard oily wastes, mercury-containing waste streams, NORM, and especially for the recovery of highly valuable drilling fluids from drill cuttings; our vacuum thermal desorption process (i.e. vacuum distillation) is economically unbeatable.
