What is Thermolysis?

Thermolysis is the thermal dismantling of organic substances (respectively rubber and plastic wastes) under oxygen shortage. During this process, waste is transformed into oil, gas, and coke.

The plant is practically energy independent. Solely the start of the machine requires energy from external sources. Thereafter, a self-sufficient cycle makes it possible to create, among other products, the energy necessary to run the machine. In some cases, an energy surplus is produced (electricity or heat).

Following types of waste/products can be recycled:

  • Used tyres (truck, car, motocycle, etc)
  • Bitumen isolations (roof isolations, etc)
  • EPDM and other elastomer rubber waste (window and door isolations)
  • PE/PET (films, bottles, diverse parts, etc)
  • Biomass (greenery, wood, food waste, etc)
  • Packaging (Tetra Pak, etc)
  • Oil shale / oil sand (Test phase)

The following products can be generated: Rubber flour, soot, coke, activated charcoal, oil, gas (similar to natural gas), electricity and warmth.

In the future, a substantial meaning will be given to the recycling of rubber and plastic wastes, even more if expensive products and energy can be created by this process. This project combines economic and ecological requirements of a waste management concept with low investment and operating costs, while recovering raw materials and fossil fuels substitutes.

The process

Our thermolysis process has different steps:

Step 1

  • Gathering of waste and storage
  • Fragmentation/cut of the waste in rubber pieces from 1 to 14 mm
  • Separation of metal and textile for re-use
  • Intermediate Storage of the waste pieces

Step 2

  • thermolysis of the rubber pieces
  • Products separation: thermolysis vapor and coke

Step 3

  • Condensation of the vapor
  • Separation of oil and gas
  • Intermediate storage of oil

Step 4

  • Cool down of the coke
  • Sifting and classification of the coke

Step 5

Creation of energy for the whole process:

  • Production of gas for the thermolysis engine
  • Recuperation of the combustion energy
  • Production of electrical energy for self-sufficiency and resale

Step 6

  • Correction of the thermolysis oil
  • Storage of the various oil types

Step 7

  • Cleaning of the drawing-off air - according to prescribed European standards

Step 8 

During the improvement of the intermediate products:  Heat, themolysis oil and coke, it is possible to obtain other products. These are, for example:

  • Coupling heat/energy with residents
  • Soot creation via thermolysis oil
  • Creation of activated charcoal via thermolysis coke

Advantages

The high profitability of this process will help to solve in an easily manner most of the environmental and recycling issues of the industrialized countries. Investing in thermolysis is an opportunity that offers high yields.
