Methods and apparatuses are disclosed by which "waste" organic fibre and other polymeric materials, chopped or shredded into strands, are oriented, packed together and tightly enclosed in strong mesh to form building blocks. The orientation of the strands and the friction between them creates a firm block structure which is particularly suited to serve as the stabilizing, shear-resisting, insulating core of stressed skin sandwich walls and other building components; methods of forming such components are disclosed. The process entails no chemical treatments or binders, and little energy, so offering a means of benign waste management and sustainable production of housing. The preferred or primary polymeric wastes are wood, cereal straw, bagasse, and other plentiful cellulose fibre materials mechanically prepared from construction wastes, tree canopy, mill wastes and agricultural wastes. A significant proportion of the block can, however, be comprised of shredded waste plastics without unduly degrading the block properties dependent upon friction between the strands.
