  • Title: Industrial recycling of vinasse.
  • Description: The production of ethyl alcohol from molasses has created a new environmental problem, namely the accumulation of vinasse (spent molasses) which, owing to its high mineral and nutrient content, is very prone to microbiological attack, and is thus liable to cause pollution problems.
  • Summary: Information contained in a recently published patent literature is required on technological processes that will enable us to use vinasse as a raw material for producing other products that might be useful in the agricultural and livestock sectors and in industry.

Example Request No.2 for a Search Report

  • Title: Rural Community Water Filters.
  • Description: Many villages do not possess the advantage of safe drinking water (filtered water) owing to the prohibitive cost of rapid gravity sand filters or slow sand filters.
    A low cost rapid gravity filter has been designed which is expected to require minimum maintenance and give best results. The filter uses the principle of sand filtration and post-chlorination arrangements; a centrifugal pump is used for periodical backwashing of the sand-bed. Preliminary trials have shown encouraging performance.
  • Summary: In order to provide safe drinking water facilities for rural communities, a rapid gravity sand filter has been designed and developed. Patent documents and possibly other relevant literature, especially of recent date, concerning development of water filtration methods for rural communities are requested.
