Summary & Process:

Pyrolysis process can be used to reprocess waste/used tyres into fuel oil, methane gas, carbon black & residue steel wires. Waste/used tyres are mainly composed of long chain of C-H molecules. The technology of pyrolysis, cracking & monomerisation of used/waste tyres is always a very hot topic with very higher returns on investment. Proposed plant recycling capacity will be 100 tonnes per day equivalent to 500,000 waste/used tyres per annum.

The pyrolysis process for recycling of waste/used tyres is a technique which heats whole or shredded tyres in a reactor vessel containing an oxygen free atmosphere and a heat source. In the reactor, rubber is softened, after softening rubber polymers continuously breaks into smaller molecules. These smaller molecules eventually vaporize and exit from the reactor. These vapours can be burned directly to produce power or condensed into an oily liquid, generally used as fuel oil. Few very small molecules which can not be condensed, remain as a gas which can be further used as a fuel to heat, reactor of the pyrolysis plant. The minerals, part of a waste/used tyre, about 49% to 45% by weight, are removed as a solid. The process of a high quality pyrolysis & distillation plant is very clean operation with no emissions or waste & conforms to ISO standards of pollution controls. By adding carbon black brequetting machines, refining plant with explosion proof motors etc., the quality of fuel oil will be at par with the industrial grade diesel which can be used in generators to produce power.

1000 Kgs of waste/used Nylon or Radial tyre can produced as follows:

- Pyrolysis or industrial diesel oil     :                       400 to 450 Litres
- Carbon black                           :             300 to 350 Kgs
- Hydrocarbon/methane gas             :                       50 to 80 Kgs
- Steel wires                            :                       150 to 200 Kgs.

Methane gas can also be used to generate power.

Cost of this project will be around US$ 2.20 million, out of which promoters' contribution will be 30% or US$ 660,000. Project implementation time will be 4-5 months.

70% debt funding against the project can be raised from local banks

Return on equity investment will be less than 12 months. Looking for a private entrepreneur who can invest US$ 200,000 against 30% equity in the project with one Director on the Board of the company. This investment will be returned to the investor immediately on the completion of first 12 months of production. Equity percentage will remain with the investor.

This is one of the most profitable industry in the world, can be set-up in most of the African countries. Presently we have obtained project clearances in Uganda, Rwanda & Djibouti. Other prospective countries in East Africa are Kenya (near Mombasa), Democratic Republic of Congo and Malawi.
