The present invention relates to a method for producing a biodegradable resin (bio- resin) material comprising the steps sieving tapioca flour using 80-100 mesh, drying said sieved tapioca flour at 45-90°C for 3-5 hours and set aside, mixing polylactic acid (PLA) with an additive mix selected from the group consisting of flow enhancers, plasticizers, and heat stabilizers for 15 to 30 mins at low speed then drying said PLA and additive mix at 45-90°C for 1-3 hours to remove moisture, adding said dried tapioca flour to said PLA and additive mix to obtain a dry extrusion blend, feeding said dry extrusion blend into a hopper of an extruder at 70-90°C, extruding said dry extrusion blend into an extrudate, and granulating said extrudate to produce a final product of bio-resin substrate granules.
