SISENER INGENIEROS SL

Their core work

SISENER INGENIEROS is a Spanish engineering SME based in Zaragoza specialising in thermal and chemical processing technologies for waste valorisation. Their core work involves designing and developing pyrolysis and thermal cracking systems to convert waste streams — initially municipal solid waste, then end-of-life tyres — into recoverable materials or energy. In the BlackCycle project they contribute engineering expertise to industrial-scale tyre recycling, helping turn废弃轮胎 into secondary raw materials for circular economy supply chains. They operate as a technology developer and process engineer, bridging laboratory-scale innovation and industrial application.

What they specialise in

How they've shifted over time

SISENER began their H2020 participation in 2018 with a self-initiated feasibility study (Pirocrack) focused on municipal solid waste treatment through pyrolysis — a broad waste stream with wide applicability. By 2020 they had narrowed their focus considerably, joining the large BlackCycle consortium specifically around end-of-life tyre recycling. This shift suggests they found a more commercially viable and technically differentiated niche within the broader thermal waste processing space, moving from generic MSW towards a high-volume, well-defined waste category with established industrial demand for recovered materials.

SISENER is moving from broad waste-processing technology development toward specialist industrial partnerships in high-volume waste streams, suggesting future collaboration interest in circular economy projects involving rubber, plastics, or other thermally processable end-of-life materials.

How they like to work

SISENER has taken both a leadership role (coordinating their own SME Phase 1 feasibility study) and a participant role in a larger industrial consortium, showing flexibility across project scales. Their participation in BlackCycle — a multi-partner Innovation Action — suggests they are comfortable contributing as a technical specialist within bigger consortia rather than always driving the agenda. With 13 partners across 5 countries from just 2 projects, they appear to work in mid-to-large networks rather than tight bilateral arrangements.

SISENER has built a network of 13 unique consortium partners across 5 countries through just two projects, indicating they joined established European consortia with diverse membership. Their geographic reach spans multiple EU member states, consistent with large Innovation Actions like BlackCycle.

What sets them apart

SISENER is a rare combination of an independent engineering SME that both initiates its own technology ventures (Pirocrack) and successfully enters large industrial consortia as a specialist (BlackCycle with €1.6M funding). Their specific focus on thermal processing of difficult waste streams — tyres and MSW — fills a niche that sits between pure research institutes and large industrial players. For a consortium needing credible industrial process engineering for waste valorisation without the overhead of a large contractor, SISENER offers focused expertise and SME agility.

Highlights from their portfolio

• BlackCycle
  Their largest project by far at €1.64M EC funding, and a flagship EU circular economy initiative targeting the industrial-scale recycling of end-of-life tyres into reusable secondary raw materials.
• Pirocrack
  Notable as a self-coordinated SME Phase 1 feasibility study, demonstrating that SISENER independently developed and validated a proprietary pyrolysis/thermal cracking concept for the MSW market.
