  1. 1. So-called High-Speed Composting Machines (Decomposers) really there are COMPOSTING machines OR its are DEHYDRATION/DRYING machines? Alfonsas BRAZAS, 29.06.2014
  2. 2. Situation on the market • There are a number of companies, which advertises that it has developed and manufactured high- speed food / kitchen waste composting units/machines. • One of the leading companies in this field is OKLIN International Ltd.
  3. 3. But... • Are these machines really a composting machines? • Are biowaste composting - biostabilisation - possible in a few hours or even a day?
  4. 4. Aerobic Digestion- composting Composting is a biological process in which oxygen loving microorganisms are used to consume organic matter and convert it into stable solids, carbon dioxide and more organisms. Aerobic microorganisms, like all living things, require three things to live and grow. They need Food, Water and Oxygen. Food Water Oxygen As these microorganisms eat and grow they produce more and more microorganisms who also eat and grow and produce even more offspring. = By optimizing the environment through agitation and temperature control, digestion of organic waste is greatly accelerated allowing large volumes to be processed in a short period of time. Aerobic digestion – composting alone can reduce food waste by as much as 50-60% by volume. A little bit of information to ponder...

  13. 13. CONCLUSIONS • Boilers / heaters are used in all of these machines for biomass heating. • Blower or vacuum pump is used to remove water vapor. • Biomass dehydration (drying) process is dominant, but not the composting process. • The product obtained by the process is dry, but not bio-stable. It really is not compost.
  14. 14. CONCLUSIONS • The so-called High-Speed Composting / Decomposing machines are actually Dehydration / Drying machines, because of Dehydration / Drying process is dominant. • The Composting process plays only a minor role - it is not essential, although microorganisms really speeds up the degradation of biowaste.
