How Gasification Works
Solid Waste

Waste Gasification

Here is the right answer: Gasification

The facts:

  • All carbonaceous materials like plastics, tires, polyurethane, CFC, biogenic material, paper, cellulose are energy carriers with a calorific value higher than any fossil fuel
  • Tires and plastic fractions account for more than 65% of the total solid waste recycled
  • The plastic fractions resulting from the WEEE recycling process are of an inferior quality due to their contamination with metal inserts from the shredding process and the mixture of different types of plastics. This makes the market value and the range of applications for this kind of material extremely low.

The gasification process:

  • As all carbon carriers, organic and non-organic is suitable for gasification
  • Gasification is a proven manufacturing process which converts carbon-containing feedstock like coal, petcocke, biomass, other solid waste into a SYNTHESIS GAS in a pressurized reactor. This gas can be used to produce electric power, hydrogen, steam, heat, fuels and chemicals.

The advantages of waste gasification over incineration are:

Gasification is less polluting as:

  • The process takes place under pressure and no poisonous gases are emitted into the atmosphere therefore
  • Contrary to incineration, where the sulfur resulting from the process is converted into harmful SOx gases, which are released into the atmosphere, during the gasification process only sulfur powder is generated. This powder can be easily collected and sold at market prices to the chemical industry
  • Unlike incineration, no hazardous heavy metals are generated during the gasification process

Gasification is less expensive as:

  • Gasification plants are about 50% less expensive than incineration plants and have a shorter depreciation period
  • The energy need of the process is significantly lower
  • No collateral damages through pollution are generated (pollution and the depreciation of property prices around the plant accompanying it)

WasteSyn is further improving on the advantages of waste gasification by developing a unique, catalyst-assisted process which lowers the reaction temperatures to below 1000°C, thereby greatly reducing the energy costs of the process.
