Abstract: The embodiments herein provide a hydrostatic backward extrusion system that utilizes hydrostatic pressure to produce products with desired cross sectional profile based on backward extrusion process. The system comprises a container, a plunger, fixed-punch, and a billet chamber. The billet material is placed inside the billet chamber. The empty space between the billet chamber and the billet material is filled with a high pressure fluid. Sealing is done at appropriate places to prevent leakage of fluid during the extrusion process. The plunger is moved down to create pressure on the fluid. Due to hydrostatic pressure, the billet material flows into the annular space between the container and the fix-punch. The design of head profile, inner and outer radius of fix-punch allows the billet material to flow smoothly into the annular and forms an extruded product.

Abstract: The embodiments herein provide an organic fertilizer based on aquatic extraction of Camellia sinensis with sodium sorbate as preservative. The organic, herbal fertilizer also acts as pesticide against the pest arthropodic species. The application of herbal fertilizer composition is environmental friendly. Further the fertilizer is applied in soil and hydrophonic systems. The fertilizer is absorbed by plant roots. The fertilizer induces systemic resistance to destructive pests for example spider mites and whiteflies. The organic fertilizer is synthesized by aquatic extraction method. The method comprises boiling 6 gram Camellia sinensis leaves in 1 liter water for 95° C. for 15 minutes, obtaining the extract, filtering the extract for removing Camellia sinensis leaves, and adding sodium sorbate at a concentration of 0.01 gram/liter as a preservative to the extract to obtain a bio-fertilizer.
