About
A Portuguese sponsor developing at Sines
Elythium is the trading name of Insurex Technologies Limitada, a Portuguese company developing an integrated xanthates, NaHS and CS₂ plant at Sines (ZILS).
Who we are
Organised, credible, in development
The project is in the development phase. Land, permitting, partner agreements, offtake letters of intent and financing are all in progress, with a final investment decision planned for December 2027 and first production targeted for 2030.
This site is a credibility tool, not a sales site. It exists to show that Elythium is a real, organised European sponsor — without disclosing anything confidential or making claims the project cannot yet support.
How we work
Principles that shape the project
Factual and modest
We say what is decided and stay silent on what is confidential or unconfirmed. We use "developing", "planned" and "targeted".
EU standards by design
Permitting, Seveso and environmental assessment are part of the development plan — not an afterthought.
Built for the long term
Around 149 permanent operating roles are planned once the plant is in operation.
Disciplined disclosure
Financials, partners and customer names stay confidential. Investment enquiries are handled privately.
Governance
Team and Board
Individual profiles are not shown at this stage. The team and Board will be added together, shortly.
Elythium is in the development phase. Plant scope, partners and timelines are indicative and subject to permitting, financing and final investment decision.
