Abstract
Abstract A shaped body made from a plurality of granulate beads of biodegradable material. The beads are subjected to either hot air or steam having relative residual moisture content of 0.5 to 2%. As a result, the beads have at least a part of their surface dissolved forming an adhesive surface. Adjacent adhesive surfaces are then bonded to each other to form the shaped body.
