  • Role of pollution control boards in municipal solid waste management

    The authors firmly believe that there is nothing like waste. It is the ignorance of the scientists and technologists that they consider a substance which cannot be utilised as waste. For example, the disposal of fly–ash was a big problem during 1990s, but now it is used in the manufacture of bricks, tiles, cement and agriculture. Similarly, the distillery effluent is used in agriculture. MSWM ...

  • Ex Situ Thermal Treatment for Soil, Sediment, and Sludge

    The main advantage of ex situ treatments is that they generally require shorter time periods, and there is more certainty about the uniformity of treatment because of the ability to screen, homogenize, and continuously mix the soils. Ex situ processes, however, require excavation of soils leading to increased costs and engineering for equipment, possible permitting, and materials handling worker ...

  • Solidification / Immobilisation of hazardous waste for subterranean storage

    The use of subterranean salt mines for the final storage of inorganic hazardous waste is state of the art in Germany, and in fact most other European countries. However, the technical requirements to prepare the waste in an appropriate way are quite challenging. Over ten years ago econ supplied a plant to a salt mine in eastern Germany. The plant uses econ’s unique batch-wise working mixing ...

  • What are filter aids?

    Filter Aids” is a group of inert materials that can be used in filtration pretreatment. There are two objectives related to the addition of filter aids. One is to form a layer of second medium which protects the basic medium of the system. This is commonly referred to as “precoat”. The second objective of filter aids is to improve the flow rate by decreasing cake compressibility ...

  • Smart Series-Odor Management

    Tackling odors at composting facilities is a manageable task made simpler by inventorying and treating all sources and tapping into technology advances. Perhaps one of the most difficult realities that had to be faced 15 to 20 years ago by the composting universe is that the phrase, “odor-free” - at least when it comes to composting - is probably an oxymoron. Feedstocks that biodegrade within the ...
