Seeking pilot sites, engineering partners and regulatory collaborators across Europe.

Aftermine

AftermineInfrastructure after extraction

Aftermine develops projects for closed and abandoned mines — starting with residual methane measurement and mitigation.

We help mine owners, public authorities and post-mining operators understand emissions, compare interventions and prepare sites for productive reuse.

The problem

Closed mines don’t stop emitting.They stop being measured.

EU underground coal mines abandoned since 2015 could emit 185–200 kilotonnes of methane a year. Basic site information — including whether they are flooded — is still missing, and new EU rules now require it.

The obligation has begun

Regulation (EU) 2024/1787 requires member states to inventory, measure, report and mitigate methane from closed and abandoned coal mines.

Pilot partnerships

Help build the first Aftermine pilot

We are looking for a closed-mine site where data, measurement and engineering partners can develop and validate an integrated methane project.

Who we want to hear from
  • Mine owners and post-mining operators
  • National, regional and local public authorities
  • Methane measurement specialists
  • Mine engineering and geotechnical firms
  • Mitigation technology providers
  • Regulatory and reporting specialists
  • Universities and applied research institutions
  • Energy, water and landscape partners
What an initial pilot could deliver
  • A site and regulatory baseline
  • A source-level measurement plan
  • A digital mine and emissions model
  • A methane mitigation options study
  • A concept engineering package
  • A monitoring and verification framework
  • An assessment of wider energy and reuse opportunities

Case study

Auguste Victoria, reworked

The framework applied to a Ruhr colliery closed in 2015 — one of the largest modelled sources in our inventory. What could be built there, what is still unknown, and what field access would have to settle.
