Flow chart of plastics recycling with the thermolysis process. 90% of the chemical energy from plastic waste is retained.

Material balance of the thermolysis process. 1,000 kg of plastic waste results in 1,000 l of paraffin oil, a high-quality raw material for plastics production.

Thermolysis — proven technology

The oldest plastics in human history are tar and pitch, formed from the thermolysis of wood. In the later industrial application of this principle (the exclusion of oxygen and temperatures above 300 °C)  other materials were also used. So far, however, only the recycling of car tyres and waste oils has been successful.

ENESPA AG will commission one of the first facilities to process mixed plastic waste into high-quality paraffin oil using the thermolysis process.

Productive systems — what matters

The challenge in processing mixed plastic waste by thermolysis is the pre-sorting of the mixed plastic waste. There is a large, dedicated global market for PET and PVC, so there are only small quantities in our input material. Humidity and the size of the waste pieces must fall within a certain tolerance range. The input material from our suppliers is checked regularly and meets these requirements.

On the one hand, the test systems were used to develop the optimum material feed and, on the other hand, to establish a processing method that also allows larger amounts of impurities.
Our modular system will only need 1 hour for the heating process, which is crucial for the system to run economically (large systems need up to several days). With our partner, we have 3 years’ experience in the continuous operation of thermolysis facilities.

Technology under control

By forming a partnership with the equipment manufacturer, we can exclude the risks of developing our own products and thus also save capital. The modules were developed over 5 years and the prototype has been running stably for 2 years. ENESPA will implement a further development of these modules with a capacity of 1,000 kg/day. The technology is ready for industrial use.

High-quality raw material is the result

In our thermolysis process, 90% of the chemical energy of the plastic waste is retained, because the result is high-quality, low-sulphur paraffin oil. The high-quality paraffin oil can  easily be used in industry and trade as a substitute for conventional crude oil for energy generation and plastic production

Investing in plastics recycling — be one of the first

With this thermolysis process, a technology has been created that solves the problem of recycling mixed plastic waste in a sustainable and intelligent way. Several locations in Germany are already interested in facilities. Raw material (plastic waste) is available in huge quantities and the sale of paraffin oil to one of the largest refineries has been secured.

For our children:
Ecological and economical
invest wisely

ENESPA AG will generate positive cash flow starting with the first investment. By operating several facilities simultaneously, revenues increase disproportionately and, accordingly, so does the value of the company. There is great demand for this technology. 18 locations in Germany are interested in operating a facility at this time.

Several sites in Germany are showing great interest in operating the recycling facilities. We will put the first facility into operation where we find the best conditions. Thanks to the mobility of the units, we are flexible when it comes to location. The business development unit of the Schwarze Pumpe Industrial Park in Spreetal is very interested in the ENESPA project. Following a thorough investigation, the responsible development bank declared the project eligible for funding. The project will be supported by the development bank once the approval process is completed.

The aim is for the first 8,000 kg/day facility in the industrial park to be commissionedby the end of 2021. As soon as this facility is in reliable operation, ENESPA will build another ten facilities and then gradually expand to forty facilities. The ten facilities are expected to be fully operational by the end of 2022.
