Abstract
The invention provides methods that use particles comprising a polymer to absorb and recover oil. The methods can be used for oil spill cleanup, oil recovery, extraction of oil from an oil-water emulsion, etc. In some embodiments, the particles are distributed to an oil spill site or another environment where oil needs to be separated. The particles may be retrieved after they have absorbed oil from the oil spill site. The oil may then be retrieved from the particles by compressing the particles or via other suitable oil removal methods.
