The invention relates to a process for recovery of useful constituents from multilayer laminated fragments arising as waste from industrial packaging manufacture. It relates more particularly to recovery of polyethylene plastic and aluminium foil from multilayered, laminated fragments containing these materials. According to the process disclosed, the delamination of the laminated constituents of the packaging waste fragments is carried out by keeping the fragments immersed in nitric acid of 50 - 70 % concentration at ambient temperature for 3 to 6 hour duration. The aluminium foils get fully separated from the plastics and the constituents remain in a submerged/floating condition. The delaminated constituents are removed from the nitric acid bath and allowed to pass through a series of baths for washing and separation of the materials. The fragments of separated aluminium foils and separated plastic are centrifuged to dryness and then allowed a sun bath for total drying. The separated fragments of aluminium foils can be used for producing aluminium ingots or sold as such. Similarly the separated fragments of plastic can be used for producing recycled plastic granules or sold as such. Click here for complete project presentation.

The present technology provides tablets with enhanced dissolution rate of sparingly soluble drugs leading to increased bioavailability. Grains of solid dispersion of the drug in water soluble carrier are formed/cemented into tablets in a manner similar to that of cube sugar. Solid dispersions of drugs in carriers of poor compressibility can be easily formed into tablets of any suitable shape/size by known cube sugar technology. Resulting tablets are not only readily dispersible owing to capillary action but also ensure rapid dissolution of poorly soluble drug because of solid dispersion. Simultaneous exploitation of well-known approaches- solid dispersion, capillary action, optional surfactant and optional size reduction in the proposed technique results in steep enhancement of dissolution rate without compromising with content uniformity.
