The Plant to produce Energy

Installation of a Waste Processing Plant for manufacturing solid fuel and downstream energy extraction. The technology processes every kind of waste (domestic and commercial), metal material is sorted out and processed separately to create added value. Also complete landfills, sewage sludge, refinery-residues, old car-tyres and arbitrary plastics etc. can be converted into energy. Final product´s are hard-pellets with a fuel value of lignite and unlimited durability. Possibly contained hazardous substances are bounded crystalline (not leachable). From the pellets, a combined heat and power plant (CHP) is able to generate electric and thermal energy without verifiable toxic-emissions.

Pelletizing in Detail: After removal of the non-useful components, the unsorted waste is crushed in an impact mill. The remaining material is then being dried. The dried material is mixed (cultivated) with the necessary additives (carbon, lime, fillers and catalysts) in a rotary drum. The exact automatically dosing of the additives guarantees the complete crystalline bounding of pollutants during the following pelletizing process and ensures that the heating value (energy-content) is of constant quality. The pellets (hard-pellets) are stable and storable without any ecological problems.

The WP Technology is ■efficient recovery of waste material and no expenses for disposal, landfill etc., ■possible toxic-emissions are avoided due to the crystalline bounding of the pollutants, ■high efficient and eco-friendly power generation, ■high availability thanks to minimising the number of rotating and flexible plant components, ■clearly structured and robust controlled engineering, ■tried and tested and high-quality machine engineering, ■simple handling and extreme operational ease.

Some benefits

  • Very low operating costs

  • Constant supply of energy

  • No landfills

  • Excellent energy recovery

  • Decentralisation if required

  • Uniquely high level of efficiency

  • Massive resource savings

  • Extreme product diversity

 
 
Comparison MVA

Brief comparison: waste is incinerated in a waste incineration plant; and waste is converted in an ALENGO waste conversion plant. The presented data represents physical examples and is based on operational plant and/or feedback from these operational plants.

Energy base: wasteApprox. 11,000 MJ per tonne of wasteCa. 11.000 MJ per tonne of waste
Useful electrical energy yieldApprox. 2,300 kw/h per tonneApprox. 400 kw/h per tonne of waste
Released pollutantsNone.
Pollutants are bound in crystals and are not released during pelletizing nor incineration.
Very high.
Even very expensive and intensive filters cannot prevent pollutant emissions.
ProfitabilityExtremely high level of efficiency due to very intensive energy yield from the waste. Waste collection charges play a subordinate role. Also no residues and therefore no landfill costs.Moderate efficiency, only achieved thanks to subsidies or extremely high waste collection charges, energy efficiency is 5 time lower in some cases. Also, landfill costs etc. are due for residual materials.
