UK SME specialising in hydrometallurgical and solvent-based recovery of platinum group metals and cobalt from secondary sources.
Env-Aqua Solutions is a UK-based environmental technology SME specialising in the recovery of critical and precious metals from secondary raw materials — spent batteries, industrial residues, and end-of-life equipment. Their technical expertise centres on aqueous and solvent-based metallurgical processes (hydrometallurgy, solvometallurgy, ionometallurgy), which align with their company name and suggest a founding capability in water-phase chemical processing. They contribute industrial and applied knowledge to large EU research consortia tackling critical raw material supply chain vulnerabilities. Their participation spans both platinum group metal recovery and cobalt extraction from battery waste, positioning them at the meeting point of environmental remediation and the clean-energy materials supply chain.
Hydrometallurgy, solvometallurgy, and ionometallurgy appear as keywords in both PLATIRUS and CROCODILE, indicating these are core technical capabilities rather than peripheral contributions.
PLATIRUS (2016–2021) focused specifically on PGM recovery from secondary raw materials, with Env-Aqua receiving EUR 172,092 — the bulk of their total H2020 funding.
CROCODILE (2018–2022) targeted cobalt recovery from end-of-life batteries, adding bioleaching and electrochemistry to their demonstrated process toolkit.
Both projects address EU-listed critical raw materials (PGMs and cobalt), indicating a deliberate strategic focus on supply chain resilience rather than general metallurgy.
Pyrometallurgy and electrochemistry appear for the first time in CROCODILE keywords, suggesting Env-Aqua expanded its process range into thermal and electrochemical routes during 2018–2022.
In their first H2020 project (PLATIRUS, from 2016), Env-Aqua's work centred on recovering platinum group metals using aqueous and solvent chemistry — a narrow, high-value niche with well-defined industrial demand. By the time CROCODILE started in 2018, their keyword profile had broadened significantly: cobalt, battery recycling, bioleaching, pyrometallurgy, and electrochemistry all appeared alongside the earlier hydrometallurgy and solvometallurgy terms. This shift mirrors the broader industry pivot toward EV battery supply chains, suggesting Env-Aqua intentionally repositioned to capture work in the rapidly growing battery materials sector while retaining their foundational aqueous-process expertise.
Env-Aqua is moving from precious metal recovery toward battery-critical metals (cobalt, lithium-adjacent) — a trajectory that positions them well for EV battery recycling consortia and circular economy mandates under Horizon Europe.
Env-Aqua has never led an H2020 project — both participations were as a consortium partner, indicating a preference (or capacity constraint) for contributing specialist expertise rather than managing projects. Despite this, they engaged with 30 distinct partners across 12 countries through just two projects, which means they entered large, well-networked consortia rather than small bilateral arrangements. For a collaborator, this suggests they are comfortable working in complex multi-partner environments and bring targeted technical input rather than broad project management capability.
Env-Aqua has built a surprisingly broad network for an SME with only two projects — 30 unique partners spanning 12 countries, implying both PLATIRUS and CROCODILE were large pan-European consortia. No repeated partner pattern is detectable with just two data points, so their network appears wide rather than deep.
Env-Aqua occupies a specific niche — aqueous and solvent-phase metal recovery applied to EU critical raw material challenges — that sits between pure academic chemistry and large industrial smelting. As an SME, they offer the agility and applied focus that universities lack, without the throughput constraints of large industrial partners; this makes them useful in consortia that need a credible small-industry voice on process feasibility. Their demonstrated coverage of both PGMs (high-value, low-volume) and cobalt (battery supply chain) within the same core methodology gives them cross-market relevance that many metallurgy specialists cannot match.
