Benefits of technology

This patented inventor describes an improved type of plumage called Wood Plastop Environmental Friendly PEN (WoodPlant). These types have unique qualities such as being able to look like real trees while also having better environmental benefits than traditional methods. They allow for creation of artificial greenery without relying on harmful chemical materials. Additionally they provide durability over longer periods compared to regular ones. Overall these technical improvements improve the quality of life surrounding usable environments through their ability to produce products from recycled lumber scraps instead of fossile timber sources.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the efficiency at producing nonpolluted green planks (PHLB), particularly when replacing or reusing existing PCL). Traditional methods involve burning up entire tree branches, resulting in waste material costs and environmental concerns such as deforestations. To address these issues, new methodologies were developed involving creation of small blocks called chips - thinning and bleaching without leaving any residual materials on top. These techniques help reduce resource usage while still maintaining their value.

Abstract

The invention relates to a polypropylene wood plastic environment-friendly pencil and a manufacturing method thereof. The polypropylene wood plastic environment-friendly pencil comprises a pencil core, and a pencil rod which is wrapped around the pencil core, and is characterized in that: the pencil rod is formed by splicing two half bodies, and each half body is made of a wood plastic composite material. The polypropylene wood plastic environment-friendly pencil avoids the problem that a wood pole pencil cannot be used due to core breaking during sharpening caused by coreshift in dadoing of the wood pole pencil, can save a large amount of timber resources, protects the environment and realize the recycling of resources and can also fulfill the aim of carbon neutrality.
