Nikolai Durov constructed spectra of commutative finitary monads (cf. commutative algebraic theory) which he calls generalized commutative rings; using a class of categorically defined localizations (which for some reason he calls pseudolocalizations), he glues such spectra to obtain generalized schemes which are a class of generalized ringed space?s.
There are many other generalizations of schemes in the literature.
