About Us
Established in 2013, Gas y Petroquímica de Occidente (GPO) is developing an ammonia production plant on Mexico’s Pacific coast in Topolobampo, Sinaloa. After completing all technical, environmental, and regulatory studies, the project secured the necessary permits and approvals.
As the first petrochemical plant in the region, and the most socially and environmentally audited private project in the country, it sets a benchmark for transparency and sustainable development.
Once operational, the plant will produce 2,200 metric tonnes per day of anhydrous ammonia, a key input in fertiliser production. It will supply a major share of Mexico’s ammonia demand, boosting local agriculture and strengthening the food security of millions of Mexican families.
In 2024, the project reached financial close, confirming full funding and triggering large-scale construction. Today, with work well underway, it stands as one of Mexico’s most strategic industrial developments with a strong focus on environmental responsibility, community engagement and technical excellence.
Project Vision
We are creating a significant number of jobs in areas such as electricity, welding, metallurgical ironwork, automation, industrial safety, and environmental protection.
Our goal is for these positions to be filled by local talent, trained at the Proman GPO Training Centre, especially designed to develop high-level technical skills.
A benefit for
Mexican agriculture
Through this project, we aim to reduce Mexico’s dependence on imports. Our plant will directly benefit farmers in the states of Sinaloa, Sonora, Chihuahua and Baja California, with more than 2,950,022 hectares designated for sowing, representing 40% of national grain production.
This will allow more producers to access affordable, high-quality fertilisers, improving their productivity and competitiveness.
Our project is aligned with Plan Mexico and the pillars of the Mexican agricultural sector, with food self-sufficiency, local supply and the promotion of development poles based on regional vocations.
A Nationwide
Multiplier Effect
The plant will have a direct positive impact on both the local and national economies — not only in agriculture, but also through the creation of infrastructure, formal employment, and technological development. This project will reposition Mexico as a geostrategic player in the international fertiliser market.

Your questions answered
Proman GPO maintains open and transparent communication with the community to address questions regarding the project. Here are some of the most frequently asked questions:
Why a petrochemical project in Sinaloa?
Access to natural gas in Sinaloa paves the way for the development of the petrochemical industry. With an initial investment exceeding USD 1.25 billion, Proman GPO is building the most modern and safest fertiliser plant in the world, strengthening national supply, the agricultural chain, and regional development.
Why is the project located within a wetland conservation area designated as being of international importance under the Ramsar Convention?
The plant is situated in an area that was already developed, with no vegetation or fauna, as verified by the Secretariat of Environment and Natural Resources (SEMARNAT) during the environmental assessment.
The project does not affect the ecological services of the Ramsar site nor interfere with migratory bird habitats. Proman GPO is implementing conservation programmes for species such as mangroves, dolphins, turtles, birds, and aquatic flora.
Globally and nationally, several industrial projects have been approved within Ramsar sites (for example, in Argentina, the Netherlands, Germany, and Mexico), provided they comply with regulations and environmental impact studies, as is the case with this project, which is supported by legal instruments and the Regional Environmental Impact Assessment (MIA).
What impact will the plant have on shrimp fishing and other species?
Studies show that the area where the plant is being built does not provide suitable conditions for shrimp larvae refuge, as it had already been impacted by other industries. Additionally, Proman GPO promotes a programme for the restocking of blue shrimp and encourages sustainable practices during the closed season.
Is the land where the project is being developed legally owned?
Yes. Proman GPO holds property deeds, federal concessions, and valid environmental permits. The entire process has been conducted in accordance with the law, with approval from municipal, state, and federal authorities. The company acts legally and remains open to dialogue, maintaining ongoing communication with communities, academics, and officials.
What benefits will the project bring to the community?
The project will generate direct and indirect employment, support for local suppliers, investment in infrastructure, and social programmes aimed at reducing marginalisation in the region.
What environmental programmes is Proman GPO implementing?
Actions have been launched to restore the Santa María–Topolobampo–Ohuira lagoon system, with the involvement of conservation experts.
Programmes include flora and fauna monitoring, mangrove protection, conservation of migratory birds and marine species, and sustainable environmental management.
