Abstract: An environmentally friendly shoe component of a shoe includes scraps and an elastic material layer within which the scraps are distributed, the scraps include bottle scraps made by crushing plastic bottles, the elastic material layer is made of thermosetting polyurethane elastomer, and at least a part of the scraps is visible by a human's naked eye.

Abstract: A method for manufacturing a shoe part includes: the first mixing step, the standing step, the second mixing step, the setting step, and the hot press forming step. The invention mainly uses the waste coffee grounds material as raw material to manufacture the shoe part. In addition to the aroma of coffee, the shoes have the functions of deodorization and dehumidification while being worn by the user, thereby achieving multiple objectives of environmentally friendly materials, low cost, strong structure and environmentally friendly after-use treatment.

Abstract: The present invention provides a shoe material part mainly composed of a coffee ground material, a porous material and a rubber-plastic material, and is made of a recycled waste porous material and recycled waste coffee grounds, which can improve the value of waste recycling and reuse, and reduce environmental pollution, in addition to reducing waste, there will be no residue pollution of natural ecology and other issues in the subsequent environmental recycling, quite in line with environmental requirements. In addition, the present invention has the function of natural deodorization, because the coffee grounds can naturally diffuse the aroma of coffee, and the characteristics of better deodorization and air permeability of the coffee grounds can be used to reduce the foul smell of a user's foot.
