– The new company, PERSEO Biotechnology is proprietary of a differential technology which transforms solid urban waste into bioethanol.

– Repsol is committed to circular economy as one of the main pillars of the transformation of its industrial complexes into large multi-energy hubs, capable of using different kinds of waste and converting them into carbon-neutral products.

Repsol, through its private equity investment fund, Repsol Corporate Venturing, and the Spanish metal-lurgical company IMECAL have created a new company, PERSEO Biotechnology. The resulting company is a spin-off of IMECAL’s innovation department, and it combines all the assets spun off from its parent company associated with a novel patented technology called PERSEO Bioethanol®. This new technology makes it possible to transform organic solid urban waste into advanced bioeth-anol 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.

The development and optimization of this technology, consisting in hydrolysis and fermentation of the raw material in a single step, represents a qualitative leap in the valorization of municipal solid waste. 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 Biotechnology has a pre-commercial scale plant in L’Alcudia (Valencia), with a capacity to process 25 tons of organic waste a day. The alliance with Repsol, through its Corporate Venturing fund, will allow the start-up company 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 effi-cient and make the range of wastes it can process more flexible.
