Which extraction method is best for EU GMP?

No method is inherently better. EU GMP applies to the facility, its procedures, its documentation and its people — not to the solvent. What changes between methods is which obligations dominate: hazardous-area control for hydrocarbon, solvent accountability and recovery for ethanol, pressure-equipment compliance for CO2. Choose on product and market fit, then engineer the compliance programme around it.

Can extraction equipment be EU GMP certified?

No. Certificates are issued to sites by national competent authorities following inspection. A machine cannot hold one, and neither can the company that builds it. Equipment can be designed to support a facility's EU GMP compliance, which is a meaningful and verifiable claim — but it is a different claim, and the difference is worth checking carefully.

Does CO2 extraction remove the need for residual solvent testing?

Not by itself. CO2 largely off-gasses at ambient conditions, which is a real advantage, but many CO2 processes introduce a co-solvent such as ethanol during extraction or post-processing. Your testing panel is determined by the market you supply and your competent authority, not by the extraction method you chose.

Which method has the lowest total facility cost?

It depends on what you already have. Hydrocarbon usually carries the highest classified-space cost; ethanol shifts cost into bulk solvent storage, recovery capacity and inventory control; CO2 shifts it into pressure-rated equipment and its documentation. Compare total installed cost including the building work, not machine price.

Can one facility run more than one extraction method?

Yes, and larger operations frequently do — typically hydrocarbon for premium concentrates alongside ethanol for volume. Because winterization, distillation, decarboxylation and crystallization are method-agnostic, the downstream train can usually be shared, which improves the economics considerably.
