Abstract: The present application provides a treatment method and device for a waste plastic. A first aspect of the present application provides a treatment method for a waste plastic, including: firstly subjecting the waste plastic to a first pre-treatment to remove impurity and grease on a surface of the waste plastic, then subjecting the waste plastics to a second pre-treatment to convert a solid waste plastic into one in flow state; and finally, subjecting the waste plastic in flow state to a first cracking treatment and a second cracking treatment in sequence. Through the method provided in the present application, while cracking the waste plastic, chlorine element in the waste plastic may be removed by a multi-stage adsorption, which reduces chlorine content in the cracked oil, reduces pressure and burden in subsequent refining, and meets the limitation of the chlorine content in cracked products in downstream processes.

Abstract: The valve box support pad is a thick rubber pad made from recycled auto tire scraps or virgin rubber by a compression molding process using a polyurethane binder and is designed to be placed below-grade under irrigation valve boxes to both support the valve box and prevent gophers or other burrowing mammals from backfilling their tunneling spoils into the valve box. What is new about this invention is that it replaces the industry standard bricks, gravel and aviary mesh used in setting/constructing an irrigation valve box assembly. The pad also reduces the amount of excavation required in setting a valve box.
