Oil refining

Internal and external oil refining

Our oil processing plants are located at our site in Hoyerswerda. We refine waste fuels, waste oils, and so-called intermediates into high-quality product oils that meet all required index values. The refined oil can be returned to the plastics cycle as a "drop-in" product and sold at the current market price.

In addition to refining our own product oils, which we obtain from chemical recycling (plastic-to-oil), we also purchase contaminated oil to refine it into high-quality specialty oils. Most of our waste oil comes from the automotive industry. A smaller portion comes from shipping or private heating oil tanks. We ensure that these waste oils are not simply incinerated or landfilled, but are returned to the cycle. We process the following waste oils:



bilge oil

Bilge oil or bilge water is an oil-water mixture that can consist of various types of oil. Oil-water mixtures are typical in cleaning agents, engine or lubricating oils, and fuels. Bilge oil is formed, for example, by unavoidable leaks in drive shafts or by water ingress due to a leak.



Oil sludge from engine and machine oil

Oil sludge is caused by the enrichment of engine or machine oil with metallic abrasion, combustion residues, etc. During an oil change, the contaminated engine or machine oil is replaced to prevent deposits that can lead to poorer protection or overheating of the engine.



mixed waste

Waste mixtures of heating oil and diesel are generated during regular tank cleaning or tank disposal. As the name suggests, they are waste products and cannot be reused.

Process in 2 steps

Oil refining is the process of processing crude oil to obtain various refined oil products (oil derivatives).

1. Filtration

The first step involves separating solid particles. Only once the solids have been removed can distillation begin.

2. Distillation

The input material is heated in a distillation column, causing it to evaporate. The lighter molecules condense at the top of the column and are removed as condensates, while the heavier fractions are removed as the bottom product (heavy oil component).

Capacity & End Product

Refining typically takes place in an industrial context. We can currently process up to 5 tons per day with our plant, but we are aiming for a capacity of 25 tons per day after expanding our German site in Hoyerswerda.

The products produced by enespa are currently sold in Germany. Our plants can produce middle distillates and heavy oils. The entire oil refining process is designed to extract high-quality products with the desired properties from the input material, the waste materials. Our end products are returned to the plastics cycle.

Our guarantee

You receive a quality guarantee for our products. Consistent quality is ensured by analyses in our own laboratory and regular inspections conducted by an independent laboratory.

When you buy pyrolysis oil or carbon black from us, you can be assured that it was produced energy-efficiently and sustainably from recycled vehicle tires.

Dr. Albert Paparo heads our research laboratory in Tangstedt. His team's work contributed to the optimization of the pyrolysis process, which now operates economically and sustainably.
