Diamond Painting, also known as Diy Diamond Painting, is a combination of exquisite and shining artificial crystal flat-bottomed round diamonds (some square diamonds) and well-designed patterns organically combined by diamond painting designers. The diamond is glued to the corresponding symbol on the canvas, so that the pasting of a diamond is completed, and then slowly fill in the area corresponding to each symbol, and it can be officially started in a few minutes. Compared with cross stitch, diamond painting has the advantages of simple operation and ease of use. To make the same pattern, the time of diamond painting is about 1/10 of that of cross stitch. Divided into crystal diamond color diamond painting, magic square diamond painting and square diamond painting!
Any kind of packaging waste may have practical value, but due to its lack of understanding or limited by certain conditions, it has not yet found a suitable use, or it has not yet been applied conditionally. From the point of view of rational and economical use of natural resources, all substances called "waste" are potential resources and should seek reasonable ways to use them. Recycling is such a process of recycling packaging waste to recover energy and resources.
With the rapid development of the economy, the amount of packaging waste has also surprisingly increased. Under such circumstances, if a resource recovery system can be established on a large scale, it will reduce the waste of raw materials and reduce the amount of packaging waste discharged, transported and handled. This will not only protect the environment, but also produce significant economic benefits and benefits. The practice of resource recycling of packaging waste in various countries of the world shows that there is great potential for the recycling of packaging waste.
To make comprehensive use of packaging waste, we must first establish a resource system. Recycling system refers to the products processed from raw materials, which become waste after people's consumption, and then introduce a new production and consumption circulatory system. As far as the society as a whole is concerned, it is a continuously circulating system of production → consumption → waste → reproduction.
The resource system consists of two systems. The pre-system is a combination of related processing technologies such as crushing technology, sorting technology, etc., to form a processing and raw material sorting process, so that the organic materials that can be biodegraded can be collected and collected to provide favorable conditions for the post-processing system. The latter system is a chemically convertible or bioconvertible material that has been processed and processed in the previous system, processed by chemical or biological conversion technology, and converted into products and energy.
Once packaging waste is produced, every effort must be made to use it, make it resource-efficient, and bring its economic benefits into full play. This is the best policy. The packaging waste that cannot be or cannot be used at present, especially the hazardous waste contained therein, must be properly disposed of to render it harmless so as to avoid causing environmental problems and public hazards.
Considering that our country's resources are not a sufficient national condition and the rapid economic development trend, the current treatment of packaging waste should focus on the research and development of resource-based technologies, and pave the way for the promotion and application of research results to create necessary conditions. . Of course, harmless technologies must also be vigorously developed and popularized.
