Biochemicals Recommendations
The benefits of petrochemicals are woven so deeply into modern life that they have become nearly invisible, which is precisely why the case for them is rarely made plainly. Petrochemicals derived from crude oil and natural gas are fundamental to agriculture, construction, automotive, electronics, healthcare, and personal care, forming the material basis for industries that employ billions of people worldwide . The sector's output, including plastics, synthetic rubber, fertilizers, solvents, and chemical intermediates, enables a vast range of downstream products that no other industry can replicate at comparable cost or scale .
Medicine offers the most immediate and least contestable example. Petrochemicals are used to produce phenol and cumene, essential precursors for manufacturing penicillin and aspirin . Petrochemical resins purify medicines and speed manufacturing, while plastics and resins form the basis of artificial limbs, artificial skin, and a wide range of medical equipment including bottles and disposable syringes . Ultra-high-molecular-weight polyethylene is the gold standard in hip and knee arthroplasty, offering wear resistance, strength, and biocompatibility unmatched by alternatives . Catheters, drug delivery implants, and vascular grafts all depend on petrochemical polymers approved by regulators for implantation in the human body .
Agriculture and food systems lean on petrochemicals at every step, with mulch films raising yields in dry conditions, greenhouse covers extending growing seasons, and irrigation pipes moving water efficiently . The Food and Agriculture Organization is explicit that in the absence of viable and cost-effective alternatives, removing plastics from agriculture would in many contexts reduce food production . Packaging, another petrochemical use, shields products in transit and prolongs shelf life, cutting waste and enhancing food safety.
Even the energy transition relies on petrochemicals, as lithium-ion batteries require separators made from polyethylene or polypropylene microporous membranes . Approximately 11 to 15 percent of an average wind turbine's weight consists of petroleum-based fibreglass, resin, or plastic, and a typical crystalline silicon solar panel is about 10 percent plastic polymer . Petrochemicals additionally furnish building insulation and lightweight electric vehicle parts, each vital for energy efficiency . The IEA has identified petrochemicals as a growing component of the energy system precisely because solar panels, wind turbine blades, batteries, and EV parts all depend on them .
The economic weight of the sector is substantial and concentrated in regions that have built competitive advantage around feedstock access and integration. Thailand's petrochemical industry illustrates the pattern: ethylene accounts for roughly 40 percent of upstream capacity, and the country's plastic use per capita reached 84 kilograms in 2022, well above the world average of 63 kilograms . Downstream production feeds packaging, textiles, automotive, and electronics, and the country ran a plastic-related trade surplus of nearly 16 billion dollars in 2022 . For refiners, integrating petrochemicals brings feedstock security, shared utilities, reduced logistics costs, and yield optimization that standalone players cannot match . Gross margins from petrochemicals have consistently exceeded refining margins, which is why companies from Reliance to Shell have steadily increased their petrochemical exposure .
The case for petrochemicals is not a case for complacency, since the environmental footprint is real and decarbonization is genuinely difficult, but the benefits are equally real and concrete. They are the penicillin that treats an infection, the hip replacement that restores mobility, the mulch film that stretches a harvest through a dry season, the separator that lets a battery store energy, and the insulation that keeps a Click Home warm. The task is not to imagine a world without petrochemicals, because no such world exists at current living standards, but to make them with lower emissions and better circularity. The benefits are too deeply embedded to abandon, and the work of making them sustainable is the work of the coming decades.
