[ Focus on Chemical Machinery Equipment Network ] Resource recovery and material application have always been a big problem in the field of product research and development, and this problem may be far more complicated than we thought.
When it comes to resource recycling, many people first think of the recycling of reusable materials, such as plastics and metals.
However, there is a type of resource that is more difficult to recover and reuse.
This type of resource is leather material.
Chemical machinery and equipment network hotspots pay attention to chemical machinery and equipmentWhen it comes to resource recycling, many people first think of the recycling of reusable materials, such as plastics and metals.
However, there is a type of resource that is more difficult to recover and reuse.
This type of resource is leather material.
Whether it is metal or plastic, these materials can usually be recycled through melting, plasticization, forging and other processes to reproduce new products, while cloth, wood and paper can be broken or dissolved and modern papermaking or bonding processes.
Become a brand-new material, but leather materials are very difficult to recycle from scraps or scraps.
To make matters worse, most leather products, due to the irregular shape of the leather itself, will naturally produce a large amount of leftovers and waste materials during use, and these leftovers and waste materials can usually only be discarded.

To make matters worse, most leather products, due to the irregular shape of the leather itself, will naturally produce a large amount of leftovers and waste materials during use, and these leftovers and waste materials can usually only be discarded.
Of course, this is not bad.
What's worse is that these waste materials are not only difficult to reuse, but also difficult to dispose of.
At present, chromium-containing dander is classified as hazardous waste, and landfill and incineration are prohibited.
Therefore, how to accelerate the resource utilization of leather materials has become a concern in the industry.
The doctoral team led by Wang Quanjie, the director of the National Tanning Technology Research and Promotion Center and Professor Wang Quanjie of Yantai University, has made a breakthrough on this issue.
It has successfully extracted the protein from the hazardous leather waste through biochemical technology and made it into basic raw materials.
Leather fertilizers that are difficult to handle and use are transformed into valuable raw materials.

Nowadays, with the continuous progress of materials research, more and more new material concepts are proposed.
At the same time, a large number of innovative materials have also appeared in our lives.
With the emergence of new materials, the recovery and reuse of waste materials will gradually increase.
In fact, most of the current research on new materials aims to replace the original materials with materials that are more environmentally friendly, easier to recycle or process, and to make the world a better place.

In fact, most of the current research on new materials aims to replace the original materials with materials that are more environmentally friendly, easier to recycle or process, and to make the world a better place.
But objectively speaking, the material problem is difficult to completely avoid because it involves an irreplaceability.
At this time, the thinking may need to be changed to how to use technology to make up for the difficult problem of materials.
For those materials that are irreplaceable and difficult to handle, the fundamental reason is that the materials themselves are difficult to handle, and the reason for the difficulty of handling is not only not conducive to natural degradation, but also the recycling value and recycling cost.
But to put it another way, with the advancement of technology, these can all be improved.

Therefore, in terms of waste and materials, perhaps the development of scientific research technology is a better solution to the material problem.
