{Manufacturing method of household goods using waste plastic}

The present invention relates to a method of manufacturing household items using waste plastic. More specifically, it is an invention of making a mixture using water-based acrylic liquid, mineral base powder, and pulverized waste plastic, and manufacturing household goods using a soft and flexible mold such as silicone, regardless of the type of waste plastic. Any waste plastic that has only excess strength can be used as a material for manufacturing products. It is possible to produce a variety of products in small quantities, and products with complex shapes can be manufactured through a relatively simple process. This waste plastic can increase the recycling rate of waste plastic. It relates to a method of manufacturing household goods using .

Plastic is a representative material widely used in modern society because it is light and has various uses.

However, with the emergence of 'eco-friendliness' around the world, plastic has been recognized as a major cause of environmental pollution, including the marine environment.

Until now, most plastics were rarely recycled and were mostly thrown away.

According to an OECD report, only about 14% of waste plastic is recycled, the remaining 62% is landfilled, and 24% is incinerated.

Accordingly, many countries around the world are taking measures to minimize the impact on the environment and establish a virtuous plastic cycle system, and the waste plastic recycling business is growing as a core model.

However, the field of recycling conventional waste plastic is mainly to produce materials that can be used as raw materials for petrochemical products through pyrolysis oil technology, which melts waste plastic and utilizes it in large-scale facilities, or classifies plastic by type and crushes it. As it is concentrated in the field of upcycled products that are melted at high temperatures and printed out of metal molds, the field of recycling waste plastics at small businesses to directly produce products that can be produced in small quantities of various types is relatively low.

Therefore, regardless of the type of waste plastic, any waste plastic that has color and strength can be used as a material for manufacturing products, and small quantity production of various types is possible, and products with complex shapes can also be manufactured through a relatively simple process. There is a need for a method to increase the recycling rate of waste plastic.
