Abstract: A method of making a recycled plastic product includes collecting recyclable plastic materials. The recyclable plastic materials are separated into a plurality of single grade batches of recyclable plastic materials. Each single grade batch is ground into a single grade group of recyclable plastic chips. A single grade portion is weighed out from each single grade group of chips. Each single grade portion is equal in weight within a range of plus or minus 15 percent. Each single grade portion is mixed together to form a multiple grade mixture of recyclable plastic chips. The multiple grade mixture is heated to form a multiple grade blend of molten recyclable plastic. The multiple grade blend is cooled into a form of a solid recycled plastic product. The recycled plastic product comprises multiple grades of recyclable plastic and a volume large enough to encompass a 1.0-inch diameter sphere.
