Problems solved by technology

[0002] With the increasing population base and the progress and development of society, a large amount of lobster shell waste and polyurethane waste are produced every year. Lobster shell is the main by-product after eating and food processing. Lobster shell is mainly composed of calcium carbonate, chitin Composed of protein and protein, these lobster shell wastes are difficult to degrade and only a small amount is reused. Usually, a large amount of lobster shell waste will be incinerated, discarded and rotted, or directly discharged into the sea, resulting in waste of resources and environmental pollution.
In addition, polyurethane waste itself is difficult to degrade and has a low utilization rate. After burning, it will cause harm to the human body and cause environmental pollution.
