BMW-Toyota Test Bio-Based Auto Materials

That shift comes as the cost backdrop remains far from benign. US benchmark WTI crude is forecast around $78.15 a barrel for July 14, after swinging from $72.45 on July 10 to $79.20 on July 13, underscoring how quickly energy costs can move. Crude has also been anything but stable over the past several years, with prices hitting $138.51 in 2008, plunging to minus $36.98 in April 2020 and topping $123.64 in March 2022. For manufacturers, those swings feed directly into feedstock costs, plastics, resins, transport and broader input inflation.

The industrial backdrop is not much calmer. US industrial production is forecast to reach 102.94 in July, up from 102.64 in June, signaling continued but modest factory activity. Producer prices, meanwhile, are projected at 295.84 in July, above 286.83 in June, suggesting input costs remain elevated even as some commodity pressures ease. That combination makes alternative materials more than a sustainability talking point: it is a margin issue.

Investors will read the BMW-Toyota effort as part of a broader race to reduce dependence on fossil-derived materials in vehicles, batteries and supply chains. Any process that lowers exposure to oil-based chemicals, cuts emissions in manufacturing or reduces long-term procurement costs could support automakers’ margins and help them stay ahead of stricter environmental rules in Europe, the US and Asia.

For the companies themselves, the experiment also reinforces how traditional automakers are competing on technology as much as on volume. Toyota, which trades in New York under the ticker TM, has been moving back above its 50-day moving average after a sharp spring selloff, while Exxon Mobil, a proxy for the energy complex, has rallied on the back of firmer oil prices. The divergence highlights the market’s current split between firms tied to hydrocarbons and those trying to build a lower-carbon operating model.

The broader narrative is straightforward: even as oil remains central to transport and industry, automakers are increasingly looking for substitutes wherever they can find them. If BMW and Toyota can turn agricultural waste and water into scalable industrial inputs, the payoff would go beyond a single material test — it would point to a new way of making cars with less oil exposure, lower emissions and potentially better cost control.

The next catalyst is whether the pilot can move beyond the lab and prove commercial viability at automotive scale, where durability, certification and economics will decide whether banana peels become a genuine industrial input or remain a headline-grabbing experiment.
