     Problem Description & Market Need

 Every year amount of municipal
solid waste (MSW) is growing in the
world (2 billion t/year)
 Incineration is the main method for
MSW thermochemical conversion
 Main problems of MSW
incineration:
• high emission of harmful pollutants
(dioxines and furans)
• high capital costs due to necessity
of expensive gas cleaning systems

                Brief technology description




 Twin fluid bed gasifier consisting of two fluid bed reactors – gasifier itself
        and combustion chamber
 Steam gasification, sand as inert material
 Wet cleaning of producer gas in a scrubber                                   5
                     Advantages
• low formation of dioxins and furans. As gasification takes
  place under limited amount of oxygen, formation of dioxins
  is much less intensive than during direct combustion of
  MSW;
• effective gas cleaning system;
• low negative impact upon environment;
• compacting effect from gasification is much more than that
  from pyrolysis. Unburned charcoal remains after pyrolysis
  while only ash remains after gasification;
• gasification is a less power-consuming process than
  pyrolysis;
• due to lower temperature during gasification as against
  combustion, formation of NOx is also much less intensive.

            Stage of development

• Detail design and
  design documentation

  is available
• Built up and tested
  50 KWth pilot unit
• Design is available for
  patenting

                                   8
       Targeted Market Segment

• Companies involved in generation and
  disposal of MSW: industrial enterprises,
  municipalities, wastes collection and
  transportation companies, landfill operators.
• Market size assessment: several thousand
  units as it is planned to install gasification
  units on existing power plants, CHP plants
  and boiler houses
• Present price of MSW disposal on landfill:
  about 2 $/m3 – in Ukraine and up to 50 $/m3
  (EU, USA, Japan, Canada).

                 Competition
• Waste incineration plants (WIP) - competitor
  Incineration of MSW is widely spread in EU, partly in
  USA and only two plants are in Ukraine. People and
  environmental organizations are often strongly against
  WIP. Expensive cleaning system is required. Typical
  problems with utilization of produced heat.
• Landfills – competitor
  Large areas occupied. High payment for MSW disposal.
• Gasification – proposed technology
  More effective and environmentally friendly MSW
  conversion. Lower price for MSW utilization. The main
  barrier – level of technical development.
