Olmeca III is a palm oil mill biogas project in Tecún Umán, Guatemala. EFI’s historical case sheet identifies Environmental Fabrics, Inc. as the fabricator and installer of the lagoon covers and biogas system. The UNFCCC separately maintains the carbon-project record as CDM project 2667. These records document different parts of the project.
What EFI installed
The case sheet identifies Grupo Hame as the owner and describes two digesters treating palm oil mill effluent. It names CIAM and Bunge Emissions Group in the engineering entry and specifies 60 and 80 mil HDPE for the covers. That is the basis for describing EFI’s installation experience. It does not establish that EFI owned the plantation, operated the generators, or held the project’s carbon credits.
The sheet, dated June 2009, reports approximately 2 MW of continuous electrical output and 24,000 cubic meters of biogas per day. Those are historical figures reported in the case history. They are not a current operating report or a guaranteed output for another wastewater stream.
What the public carbon record shows
UNFCCC project 2667 lists Guatemala as the host country and records registration on November 23, 2009. Its listed participants are Olmeca S.A. and Bunge Emissions Fund Limited. The record includes the project design document, validation material, monitoring reports, and issuance histories. The registry lists its 2009-2016 crediting period as expired, with renewal no longer possible.
The project page lists expected annual reductions of 37,377 metric tonnes of CO2 equivalent. It also records separate issuance requests marked Issued for specific monitoring periods. A projected annual reduction and an issued credit quantity describe different things. Neither figure establishes the amount of credits sold or the revenue received.
How to read a historical reference
Start with the named facility and the scope performed by each contractor. Then identify the date and basis of any performance figure. A design estimate, a case-sheet report, and a metered result over a defined period should remain distinguishable in a proposal or project comparison.
Carbon documentation adds another layer. A covered lagoon and flare establish an equipment configuration. Registration, monitoring, verification, and issuance require their own records. The Olmeca registration cannot be transferred to a different farm because that farm uses similar equipment.
Mexico project histories have their own evidence
The La Joya and El Capricho case histories describe Mexican livestock biodigesters and on-site power generation. They should be assessed through their own named records. The source review for those histories did not establish project-specific CDM issuance, so this article does not assign Olmeca’s carbon history to either installation.
For a proposed biogas system, provide the wastewater characteristics, flow range, intended gas use, and required installation scope. EFI can then discuss the relevant cover and gas-system work. Any carbon-credit claim needs a separate, identified project record and supporting documentation.
