Liquefied petroleum gas is a commodity produced by oil refineries and sold as a fuel for cooking, heating, grain drying, forklift trucks, and even backyard barbecues.

“That butternut squash, it’s got to get cooked tomorrow,” she says. “It’s on the edge.” Even if the produce isn’t perfect, Baynor finds a way to use it. Bruised apples are mashed into applesauce.

—Indonesia halts exports of palm oil, a critical raw material for surfactants and other chemicals “” Indonesia halted the export of some types of palm oil April 28 in response to rising prices for cooking oil due to Russia’s invasion of Ukraine. Palm oil is a component in an overwhelming variety of foods worldwide and is a critical raw material for surfactants and other biobased and semisynthetic chemicals. The conflict in eastern Europe is disrupting the edible oil market in part because Ukraine and Russia produce a large portion of the world’s sunflower oil, which is similarly used in cooking and as a biobased chemical feedstock. “Indonesia is the world’s largest producer of palm oil, and they control 60% of palm oil exports,” says Shara Ticku, CEO of the biotech palm oil substitute maker C16 Biosciences.
