• Main activities of GTE International Holding
  Company
• Supply of environmentally friendly technologies
• Project management and implementation on which
  the plant has to be built. Examination of the
  context and analysis.
• Pre-feasibility study this study assesses
  whether the project is actually feasible,
  considering the potential obstacles and the
  technical and economic opportunities.
• Detailed feasibility study this definitive
  document indicates whether the project can really
  be realized, considering all the conditions and
  assessing the sustainability of the system and
  technology.
• Plant design precise definition of all the plant
  components of the relevant technology. This
  includes mechanical-, electric-, and functional
  drawings, plans and flow charts are drawn up for
  the construction, installation and commissioning
  of the plant.

Depolymerization Technology
Waste plastics and tires are long-chain polymers,
containing more than 50,000 carbon atoms,
directly linked by the cross-link or branched
chains. Depolymerization decomposes the
long-chain to shorter chains.
Depolymerization is the process of the molecular
decomposition, larger molecules are cracking to
smaller molecules.

Depolymerization Technology

• The result is the generation of
• Poly-fuel - green synthetic (fuel) oil
• Poly-carbon - soot (carbon black)
• Poly-gas - synthetic gas
• Environmentally friendly, dealing with the
  comprehensive issue of waste disposal
• Energetically independent, using the input
  material for its own operation, while at the
  same time it is possible to generate electric
  power and heat (CHP) and comprehensively -
  ecologically and energetically utilize waste
  polymers

Depolymerization Unit
The thermal decomposition means chemical
breakdown of polymer chains at oxygen-poor or
oxygen-free environment in a properly designed
reactor. In this way, the energy content of
plastic waste is recovered better efficiency.
Also a big advantage is that the resulting
liquid, gas and solid products can utilize as
primarily energy source and secondly the chemical
industry can use as secondary raw materials.

Depolymerization Unit

• Technology Benefits
• Lower reaction temperature, ranging from the
  minimum of 275 C up to 445 C at maximum
  (depending on the type of the input material)
• Synthetic oil recovery ratio higher by 10
  compared to other technologies
• Process with zero emissions no damage to
  environment
• Shorter reaction time and larger power savings
• Optimum conversion of polymer waste to
  hydrocarbon fluid with negligible trace of wax
• The most modern cleaning systems ensuring that
  the content of sulphur in the synthetic oil to be
  lower than 75 ppm
• Patented highly effective catalyst with very
  low impacts for production process
• Continuous production process with lower demand
  for labour and operators and more

Benefits of Depolymerization Process

• Low-temperature catalytic depolymerization of
  plastics, oils and tires offers the following
  benefits
• generates quality fuel with near-zero emissions
• facilitates to solve the issue of the soil
  pollution with plastic, oils and tires
• recovers energy from the waste
• helps to recycle the carbon with its subsequent
  utilization.
• The waste breaks down to utilizable end products
  synthetic oil, gas and soot

11
Depolymerization input-output ratios

• Conversion of waste plastic and tyres to
  synthetic oil, soot and synthetic gas
