A concrete dowel placement system and methods for making the same. The system allows for accurate and easy substantially-parallel or parallel placement of slip dowels within sections of concrete so that adjacent sections of concrete may be allowed to undergo thermal expansion and contraction while remaining in a common plane without cracking or faulting. The system includes a coupler and a sheath. The sheath is configured to be slidably extensible over the coupler and may be held to the coupler by friction. An outer surface of the sheath may be textured. Additionally, a method of constructing the concrete dowel placement system includes extruding material to form two tubes of different sizes. The tubes are then attached to each other, then material is extruded or injection molded to form a sheath. Alternatively, construction may include extruding material to form a tube, then removing some of the material from the tube in order to form a coupler.

A method of making recyclable waste contains steps of: a step of collecting so that the recyclable waste is collected and classified to industrial waste and daily use plastic; a step of crushing so that the industrial waste is crushed into granules, and the daily use plastic is made to raw materials; a step of mixing so that the granules and the raw material are mixed in a weight ratio; a step of heating and plasticizing so that the granules and the raw materials are maintained in a temperature to obtain plasticity in a flowing speed; a step of extruding so that the granules and the raw materials are extruded in a predetermined shape and a predetermined length, thus forming a body. Furthermore, the method further contains a step of cooling so that the body is cooled to solidify and to be make a recycled green building material.
