A storm-drain insert has separate collection systems for trash and oil or other hydrocarbons. A tilted grate separates trash from oily inlet water and directs the trash to a separate basket, and the water flows through a corrugated, flexible canister containing a hydrophobic, compliant, oil-absorbent, copolymer material arranged in a number of bodies having high surface area. Preferably, the material is formed with a binder in a novel extrusion process. The inserts can be suspended in a storm drain adjacent to a curb inlet.
