Abstract

The present invention relates to drinking straws that are made from biodegradable material or bioplastics. The process to manufacture the present invention can use waste lipid wax byproducts. The present invention can incorporate chemical modification of corn or hemp fiber waste, and is comprised of wax byproduct, xanthan gum, carnauba wax and stearic acid. Stearin, hardener and plasticizers are mixed with corn or soy wax. A binder ingredient can be added to the waxes and fiber mixture, resulting in a smooth and hard, durable and biodegradable material with a high melting point. This material is then processed using an extrusion method, whereby the mixed ingredients are forced through an opening in a perforated plate or die with a design specific to form a straw, and then cut into a specific size by blades. The extruder consists of a large, rotating screw tightly fitting within a stationary barrel, at the end of which is the die. Extrusion enables mass production of food via a continuous, efficient system that ensures uniformity of the final product.

Claims (20)

1. A disposable drinking straw comprised of a biodegradable material formed by an elongated tubular body suitable for allowing a user to use said straw for consuming a beverage, and wherein said elongated tubular body is formed from corn stalk-based ingredients, and comprised in part of a wax byproduct formed during an oil distillation process whereby oil waxes and lipids undergo a process of winterization and the resulting wax byproduct is combined with a stearin, a hardener, and a plasticizer to create the biodegradable material.

2. A disposable drinking straw according to claim 1 wherein said stalk-based ingredients includes husk fibers of a corn plant and a binding agent.

3. A disposable drinking straw according to claim 1 wherein said stalk-based ingredients includes the dehydrated silk of a corn plant mixed with a binding and hardening agent including any biodegradable environmentally safe compound.

4. A disposable drinking straw according to claim 1 wherein said stalk-based ingredients includes the kernels of a corn plant grounded into a state which supports cohesion to a biodegradable bonding agent after removing corn oils from said kernel.

5. A disposable drinking straw according to claim 1 wherein said stalk-based ingredients includes the dehydrated cob of a corn plant mixed with a binding and hardening agent including any biodegradable environmentally safe compound.

6. A disposable drinking straw according to claim 1 wherein said straw is constructed of dehydrated fibers from sun flowers.

7. A disposable drinking straw according to claim 1 wherein said straw is constructed of fibers from a corn plant, wherein oils from said corn plant is separated from said fibers, ground up, and then bound together with xanthan gum.

8. A disposable drinking straw according to claim 1 wherein said straw is constructed of fibers from a corn plant in a grounded state for cohesion and to maintain thickness, and then bound together with carnauba wax.

9. A disposable drinking straw according to claim 1 wherein said straw is constructed of fibers from a corn plant in a grounded state for cohesion and to maintain thickness, and then bound together with beeswax.

10. A method for making a disposable drinking straw comprising the steps of forming a biodegradable material into an elongated tubular body suitable for allowing a user to use said straw for consuming a beverage, and wherein said elongated tubular body is formed from corn stalk-based ingredients, and comprised in part of a wax byproduct formed during an oil distillation process whereby oil waxes and lipids undergo a process of winterization and the resulting wax byproduct is combined with a stearin, a hardener, and a plasticizer to create the biodegradable material.

11. A disposable drinking straw according to claim 10 wherein said stalk-based ingredients includes the husk fibers of a corn plant and a binding agent.

12. A disposable drinking straw according to claim 10 wherein said stalk-based ingredients includes the dehydrated silk of a corn plant mixed with a binding and hardening agent including any biodegradable environmentally safe compound.

13. A disposable drinking straw according to claim 10 wherein said stalk-based ingredients includes the dehydrated kernels of a corn plant.

14. A disposable drinking straw according to claim 10 wherein said stalk-based ingredients includes the cob of a corn plant being finely milled for combination with a wax substance.

15. A disposable drinking straw according to claim 10 wherein said straw is constructed of fibers from sun flowers and degrades into constituent components upon prolonged exposure to a liquid.

16. A disposable drinking straw according to claim 10 wherein said straw is constructed of fibers from a corn plant, wherein oils from said corn plant is separated from said fibers, ground up, and then bound together with xanthan gum.

17. A disposable drinking straw according to claim 10 wherein said straw is constructed of fibers from a corn plant in a grounded state for cohesion and to maintain thickness, and then bound together with carnauba wax.

18. A disposable drinking straw according to claim 10 wherein said straw is constructed of fibers from a corn plant in a grounded state for cohesion and to maintain thickness, and then bound together with beeswax.

19. A disposable drinking straw comprised of a biodegradable material formed by an elongated tubular body suitable for allowing a user to use said straw for consuming a beverage, and wherein said elongated tubular body is formed from corn stalk-based ingredients and wherein said stalk-based ingredients includes the husk of a corn plant and wherein said husk is ground up to form a powder and then dried, and wherein said dried husk powder is extruded into a drinking straw by combination with a heated emulsifier consisting of carnauba wax formed during an oil distillation process.

20. A disposable straw according to claim 19 wherein said straw is combined with a biodegradable hardening agent to enhance straw structural integrity while also enabling a gentle degradation after prolonged exposure to a liquid.
