US-Bulgarian Partnership Targets Green Methanol Production from Waste in Bulgaria

US-based HyOrc Corporation has entered into a binding agreement with Bulgaria’s OnEnergy Group to co-develop a waste-to-methanol production facility, according to Ship & Bunker. The deal positions HyOrc as the technology partner for stage 3 of the project, which centres on transforming refuse-derived fuel (RDF) into green methanol.

Facility Design and Production Targets

As reported by Ship & Bunker, the facility is designed to process approximately 50,000 metric tonnes of RDF per year across around 330 operating days. Daily feedstock intake is estimated at roughly 150–155 mt, with projected methanol output of approximately 38–42 mt/day — though the report notes this remains subject to final design.

EU Alignment and Funding Support

The project forms part of a broader waste-to-energy platform that OnEnergy Group is developing in alignment with European Union objectives, including decarbonisation targets, circular economy principles, and the reduction of landfill dependency. Ship & Bunker also notes that HyOrc will contribute to technical workstreams supporting funding applications, including potential pathways through the EU Innovation Fund.

Implications for Marine Fuel Supply

Ship & Bunker highlights the broader relevance of projects like this one to the shipping sector. As dual-fuel methanol vessels continue to enter service and regulatory pressure on emissions intensifies, demand for green methanol as a marine fuel is expected to grow. Waste-to-methanol initiatives are increasingly being viewed as important contributors to future alternative fuel supply chains.
