  • Degassing Refrigerators - Drill-head and Piercing-plier

    1. For what purpose do we have to degas a refrigerator? A refrigerator has to be disposed as hazardous waste. The refrigerants inside a hazardous refrigerator are harmful for the environment (ozone depleting and greenhouse effect). Most common refrigerants are; R12, R134a and R600a. The uncommon is the removal of NH3. Refrigerants are developed to dissolve very easily into ...

  • FTIR gas analysis improves container safety

    Introduction Entry to freight containers represents a significant hazard to staff responsible for inspection, stuffing or destuffing because of the large number of airborne chemicals that can be present. Research in Germany and the Netherlands found hazardous levels of gases and vapours in around 20% of all containers and this level of contamination is now accepted as commonplace. It ...

  • Wastewater-Primary Treatment

    Primary Treatment is defined as a wastewater treatment process that takes place in a rectangular or circular tank and allows those substances in wastewater that readily settle or float to be separated from the water being treated. This process achieves solids separation. The solids readily available to settle to achieve sedimentation will do so in a settling tank referred as a clarifier. On the ...


  • Raising energy efficiency in a new materials economy - Part II

    There is a vast worldwide potential for cutting carbon dioxide (CO2) emissions by reducing the use of materials. This begins with the major metals--steel, aluminum, and copper--where recycling requires only a fraction of the energy needed to produce these metals from virgin ore, and with the recycling and composting of most household garbage. It continues with designing cars, appliances, and ...

  • Green Green Grass

    A few years ago the North Sea managed a twelve month period without any major shipping disasters. Good news for the environment you’d have thought. However, in the same period up to one hundred thousand tonnes of oil were estimated to have been released into the sea. Some of this can be put down to natural occurrence, but by far the major part is dispersed from aircraft and shipping fleets ...


  • Properties and Behavior of Inorganics in Contaminated Soil

    Often, specific technologies may be ruled out, or the list of potential technologies may be immediately narrowed, on the basis of the presence or absence of one or more of the chemical groups. The relative amounts of each may tend to favor certain technologies. Metals may be found in the elemental form, but more often they are found as salts mixed in the soil. At the present time, treatment ...
