Repsol and IMECAL form technology venture for waste valorization

Spain-headed oil and multi-energy major Repsol S.A has recently announced that it has through its private equity investment fund, Repsol Corporate Venturing, partnered with compatriot metallurgical company IMECAL S.A to form PERSEO Biotechnology. The new joint venture, in which Repsol will have a 25 percent stake, will act as a commercialization company for an advanced biofuels technology developed by IMECAL.

A spin-off of IMECAL’s innovation department, PERSEO Biotechnology will combine all the assets spun off from IMECAL associated with a novel patented technology called “PERSEO Bioethanol”. This proprietary conversion technology makes it possible to transform organic solid urban waste into advanced bioethanol in a profitable manner.

It not only improves waste management, reducing the amount that goes to landfills, but also transforms it into high value-added products that can be used as fuel with a low carbon footprint.

According to Repsol, the development and optimization of this technology, which consists of hydrolysis and fermentation of the raw material in a single step, represents a “qualitative leap” in the valorization of municipal solid waste (MSW).

In addition, among the most notable advantages of this process are the high yields compared to other options, its modularity, and its complementarity with existing facilities. PERSEO Bioethanol

IMECAL has a pre-commercial scale plant in L’Alcudia, Valencia, with a capacity to process 25 tonnes of organic waste a day. The alliance with Repsol will enable PERSEO Biotechnology to accelerate the scale-up of the technology to reach the commercial phase, taking advantage of the multi-energy company’s extensive experience in this field.

At the same time, both companies will collaborate on different projects to make the PERSEO Bioethanol technology more efficient and make the range of wastes it can process more flexible.

Repsol is committed to the circular economy as one of the main pillars for transforming its industrial centers into large multi-energy hubs, capable of using different types of waste and converting these into carbon-neutral products.

As announced during the presentation of its 2021-2025 Strategic Plan, the company’s ambition is to use four million tonnes of waste per year by 2030.
