FAQ about PWED

Is the end product, oil and gas, directly for sale? What specification is it?

Yes. The conversion yields 70% petroleum products, 25% gas products and 5% coal dust. 70% of the final oil product is diesel and 30% is gasoline. Its caloric value is 38-42 MJ/kg.

The final gas product has a calorific value of 42-46 MJ/kg.

What other types of plastic can be used? Can PET and rubber granulate be used?

PET can be used, but of course the highest quality end products come from plastic packaging waste such as PP, PE, PA and other plastics.

In the case of rubber, due to the high sulfur content, the petroleum product will be of lower quality, and due to the high carbon content, the generated coal dust will be 45-50%, the oil content 25-30%, and the gas content 15-20%.

What are your warranty requirements? How long is the warranty?

The warranty complies with the normal operating rules provided by the manufacturer.

The mechanical warranty period is 18 months from the date of delivery.

What is the failure rate?

Each component is made of the highest quality materials. The device is made of stainless steel, and the reactor itself is made of heat-resistant steel.

The usual quality of components is increased by 20-30%.

Control is fully automatic, built-in sensors control everything.

The error rate is minimal, and if it happens it can be easily corrected.

What about transportation and installation costs?

These costs are included in the selling price at German parity.

What about putting the system into operation and training for the employee?

These costs are included in the sale price.

Employee training takes place on site, during commissioning and trial operation.

What is the life of the machine?

As already mentioned, the components are made of high quality materials, all standards are overcapacitated 20% to 30% and all processes are under strict control, so the life of the machine is more than 20 years.

Which patents are used and under which number?


“Thermal decomposition process of organic materials
PCT/ HU2016/050021″.


“Flash pyrolysis reactor PCT/HU2016/050022”.

Does the machine have CE certification for Germany (EU)?

The CE certificate is issued together with our partner manufacturing companies when the technology is delivered.

How many reactors can work together?

The technology is modular, so expanding the number of reactors is relatively simple and any amount of processing capacity can be built.

What happens if foreign substances enter the reactor: such as water, iron and/or organic matter?

The cut plastic base material of 15-30 mm contains only at least 5-10% of surface moisture, which is dried using an agglomeration unit.

The supply unit has a metal door for separation. During the process, the minimum size of the metal part enters the generated carbon powder that exits the reactor as a product.

A few percent of organic matter can enter the reactor, it does not cause an operational problem, it can only worsen the quality of the oil produced.

What does your support look like if the machine stops?

Shutdown happens continuously, whether it happens directly or not. The control unit and the vacuum pump are equipped with an uninterruptible power supply, so that they can be switched off gradually. The filling is stopped first, after which the process of processing the still existing raw material is gradually stopped as the technology cools down. In addition, in the event of an emergency shutdown, the inside of the reactor is flooded with inert gas, so that no explosive mixture can be formed.

In which language are the instructions and software?

The instructions and software are originally in Hungarian, German and English. But at the request of the customer they can be translated into the required language.

Has an endurance test been conducted?

Yes. The equipment was started and stopped more than two hundred times in one or more days, during which the thermal expansion and regeneration of the equipment elements took place without any problems and no maintenance was required. During start-up, the raw material left in the equipment did not need to be removed.

What are the dimensions of the raw material that enters the machine?

The size of the raw material is 15-30 mm.

How many days (24h) can the machine run without stopping?

We performed the so-called “shock endurance test” for 12 months and more than 200 times a day. Thermal expansion and regeneration, possible unloading of raw materials and transformation after reheating, and the quality of the obtained oil and coal dust was stable.

In your calculation you assume that 1MW costs cca 30 €, but that would only be 0.03 €/kW.

In EU, is the minimal price for 1MW €148, that is €0.148 for 1 kW.

What percentage of PET plastic, in the raw material, is possible without poor results? What about terephthalic acid during PET processing? Does that mean higher consumption of parts?

PET is not bad, it gives only 5-10% less oil because it contains oxygen radicals.

During the processing of PET, benzoic acid is formed, which is bound during the technological process.

This does not create a problem, as it can only occur during condensation of oil vapors and gases, where there are no more wearing, rotating parts.

At first we heard something about a 15 year warranty! She is now 18 months old. Really little for such a quality machine.

15 years can be misleading information. The technology is made of steel and heat-resistant material with a durability of more than 20 years. Our company cooperates with our partner with a general European guarantee and lasts for 18 months.

What do you mean by “speed 2-5 per minute”?

The rotation speed of the spiral shaft inside the reactor is 2-5/min. This is a major part of the technology, there is a complete change in the state of the molten raw material and the formation of hydrocarbon and gas vapors. In addition to technology, there are two other rotational movements where wear and tear can occur. One is for powering, melting and overheating the feed-stock on the transmission screw shaft.

Its speed is 50-60/min. Its manufacturer is a well-known company (EREMA) that has been supplying extrusion machines to the world for decades.

At the end of the second reactor, the crushed coal is stored on a screw shaft at a speed of 35-40 rpm. This technical characteristic is important because of the service life and wear resistance and the warranty for the machine units.

Who owns the patent (person or company)?

The inventor and owner of the patent is an individual, director and majority owner of a sales company, and we patent the technology worldwide, currently in more than 170 countries.

Is the machine certified?

Yes, it is certified for CE and TÜV Rheinland. Of course, all manufactured equipment is certified for these two systems, ie we supply the technology with CE and TÜV Rheinland certificates.

How many foreign plastics (eg PVC) can be in the raw material without any problems with the machine?

PVC< = 2-3 %

What does your support look like if the machine has problems and stops?

Depending on the report and the quality of the error, we will begin troubleshooting within 24-72 hours. We provide free replacement of worn and rotating parts during the warranty period, as well as quarterly maintenance, after which we will do all this for the amount of 50,000 EUR per year.

How many days (24h) does endurance last without stopping?

In a one-year trial run, a 1-day stop for monthly inspection was performed. During this time, parts did not need to be replaced, only minimal dust removal and decreasing work had to be performed. There was no wear and tear.
