In this paper we propose a bisimulation technique for proving behavioural equivalence of such systems modelled in the \\emph{higher-order $\\pi$-calculus with passivation} (and restriction). Previous research for this calculus is limited to context bisimulations and normal bisimulations which are either impractical or unsound. In contrast, we provide a sound and useful definition of \\emph{environmental bisimulations}, with several non-trivial examples.
