Oil, plastics and climate: Why higher prices could speed a materials transition

The recent closure of the Strait of Hormuz has triggered a significant surge in production costs for conventional plastics, which rely heavily on oil and gas feedstocks. As crude prices fluctuate, the maritime supply chain faces mounting pressure to pivot toward sustainable alternatives. This economic shift impacts major tanker operators like Bahri and Euronav, forcing a re-evaluation of cargo logistics and material sourcing. With global trade routes through the Persian Gulf disrupted, the industry must now accelerate its material transition strategies.

This transition aligns with the stringent requirements of MARPOL Annex V, which strictly regulates the discharge of garbage from ships, including synthetic materials and plastics. Compliance departments must ensure that vessels adhere to the International Maritime Organization’s (IMO) 2023 guidelines on plastic waste management. As operational costs rise, shipowners are increasingly scrutinized under SOLAS Chapter VII regarding the safe carriage of chemical cargoes. Failure to optimize material usage not only impacts profitability but also risks non-compliance with evolving environmental port state control inspections.

Chief engineers and second engineers must now prioritize the inventory management of plastic-based consumables and spare parts onboard. These rank groups need to implement stricter waste segregation protocols and evaluate the durability of synthetic components during routine maintenance. By monitoring the rising costs of oil-derived materials, technical officers can better justify the procurement of sustainable, long-lasting alternatives to their shore-based management teams, ensuring both operational efficiency and adherence to tightening environmental regulations during long-haul voyages.
