Introduction The use of porous concrete was introduced into Japan as an ecological material[1].
In another one, air bubbles are introduced into the fresh concrete or mortar mass to produce a material with a cellular structure[3].

Introduction Manufacturers are currently faced with new challenges such as global warming, landfill limitations and virgin materials decreasing sources.
Beside the green issues, profit-orientated motivations through product recovery and using recycled instead of virgin materials are further reasons for remanufacturing and recycling of used products.
The network can recycle 16,000 metric tons of copper and 4,000 metric tons of other materials that are included in wiring harnesses such as PVC and plastic sockets.
Since non-copper materials can be sold to third parties, the company can be gained in this way along with using recycled copper instead of virgin copper to produce new wiring harnesses.

In this regard, the study of changes in high-elasticity properties of flexo plates during their swelling in low-molecular liquids used in printing is relevant and highly-demanded in science.
A light-protective film was removed from the original photopolymer plates, the lavsan base was peeled off from below, and the resulting photopolymer material was exposed to ultraviolet radiation on both sides.

There are a lot of studies on the essence and the connotation of product design, the representative one is the research from philosophy or cognitive science.
Firstly, product design is a brain-based thinking activity because the brain is the material foundation for thinking.
