Enviro, Nynas in link-up to enhance pyrolysis oil

Stockholm – Recovered carbon black (rCB) manufacturer Scandinavian Enviro Systems, in partnership with RISE (Research Institutes of Sweden) and processing oil company Nynas AB, has launched a project to further refine its pyrolysis oil recovered from waste tires.

The research follows a study conducted last year which showed that the oil extracted through Enviro’s end-of-life tire (ELT) pyrolysis technology could be mixed in and used as a fuel such as diesel, Enviro said in 20 Nov statement. 

In this new project, the companies aim to further develop manufacturing processes where fractions of the pyrolysis oil are converted to base oil products such as lubricating oils and process oils.

“This project seeks to increase the economic and environmental profitability of both tire pyrolysis and tire recycling in general, and to promote the sustainable conversion of refineries for base oil production,” said Linda Sandström, the project manager at RISE ETC.

The partners, she added, expect that the project would contribute to “a sustainable tire recovery” that utilises the tires’ components while reducing fossil fuel consumption.

Enviro’s objective of the project, according to the company, is for its pyrolysis oil to be priced on the basis of its value to the petrochemical industry both as a fuel and as a sustainable product.

The oil, it claims, contains large proportions of bio-based raw material from the natural rubber used in tire manufacturing.

According to Enviro, the company extracts about 500kg of pyrolysis oil from a tonne of tires through its patented pyrolysis technology.

Operating a plant with the processing capacity of 30 kilotones per annum (ktpa), the company can produce 14ktpa of pyrolysis oil per year, Enviro CEO Thomas Sörensson noted

“The financial potential is therefore substantial,” the CEO concluded.
