Bahia Oil & Gas Energy 2026, which opened this Tuesday (27) and runs through May 29, brought integrated solutions for the transportation, treatment, and environmental recovery of industrial waste generated by the oil, gas, petrochemical, naval, mining, and healthcare industries operating in the North and Northeast regions.

One of the highlights of the fair's first day was precisely the advancement of environmental solutions aimed at the treatment, transformation, and proper disposal of waste produced by the oil and gas chain—a topic that has taken center stage in light of the growth of energy activity in Bahia, one of the country's main industry hubs.

The expansion of the oil, gas, petrochemical, and heavy industry sectors in the North and Northeast also increases the demand for environmental structures capable of transporting, treating, and transforming highly complex industrial waste. The topic is on the agenda at Bahia Oil & Gas Energy 2026, held at the Salvador Convention Center.

According to projections by the Energy Research Office (EPE), national oil production is expected to grow by about 40% by 2034, driven by the expansion of the pre-salt and offshore operations. The growth in activity increases the volume of industrial waste generated by the oil and gas segment and requires structures capable of meeting the demands for operational safety, traceability, and environmental efficiency.

"Environmental management is no longer just an ancillary requirement—it has become part of the industry's own operational logic," says Paulo Marcelo Santana, co-CEO of Grupo Marquise.

This year, the fair features the participation of CTR Bahia, a Marquise Ambiental company, which is presenting its hub of environmental services and solutions for heavy industry. The complex brings together integrated solutions for the collection, transportation, treatment, and environmental recovery of industrial waste generated by sectors such as oil and gas, petrochemicals, the naval industry, mining, and healthcare, including blending, co-processing, tank cleaning, effluent treatment, and environmental liability recovery.

Marquise Ambiental, one of the largest waste and environmental solutions companies in the country, is a national benchmark in waste management and operates CTR Bahia, the leader in the treatment and environmental recovery of waste from the industrial segment, especially oil and gas, in the State of Bahia. The complex handles operations that generate materials with high environmental contamination potential, such as oil-contaminated waste, industrial effluents, sludge, materials from tank cleaning, naval operation waste, healthcare waste, and industrial waste classified as hazardous.

Installed on a 79-hectare site, the complex features a hazardous and non-hazardous waste landfill, a blending plant, an effluent treatment station, an autoclave for healthcare waste, and an industrial cleaning structure. The operation allows waste with different characteristics to be treated, reused, or transformed according to its classification and legal requirements.

"When we talk about oil, gas, petrochemicals, and the naval industry, we are dealing with operations that require technical control at every stage of waste management," says Felipe Villa, superintendent of CTR Bahia.

This need has increased the demand for integrated structures capable of handling different industrial flows within a single complex, explains Paulo Studart, Operations Director of Marquise Ambiental.

"Every industrial operation generates waste, and the proper transformation of these materials has become part of the operational safety, efficiency, and environmental responsibility of industrial activity itself," he says.
