A method for permanently compacting a hollow resilient structure such as a recyclable plastic container to facilitate recycling thereof. As the structure is compressed cutting blades provided on the compressing surface perforate the walls of the container thereby cutting interlocking tabs into the surface. At the same time the interlocking tabs are forced outward and through the cavity left in the walls of the container by displacement of the tabs. The tabs straddle the cavity and become locked against the walls of the container by the separating force of the resilient plastic.
