Why we need recycle the waste toner cartridges
Many people are suggesting to protect our earth through recycling those things which can be reused. About those waste toner cartridges, we also need to recycle them, and we must know if use cheap toner cartridges, which have not longer life, it means make more waste for the earth.

The steady growth of modern office equipment has also brought with the matching ink cartridges, toner cartridge and other supplies to 30% annual rate of increase. And these non-degradable supplies, as garbage disposal is not only a waste of resources, but also increasingly threatening people's living environment. From Table 1, it can be concluded that the output of the laser supplies market in China has increased year by year, the growth rate of the whole toner cartridge components is about 9%, and the growth rate of the recycled toner cartridges is about 40%. Based on this growth rate, it is expected that by 2009 the amount of waste toner cartridge will exceed the new toner cartridge, usually 10-20% of the weight of the waste toner cartridge. Plastic accounts for about 18% of the weight of the exhaust gas cartridge. In the waste toner cartridges, the greater harm to the human body is the toner. The main ingredient in toner carbon black has carcinogenic effects, it has been the International Cancer Research Organization (IARC) included in the list of carcinogens. If the recovery and re-use of solid waste such as cartridges can not be conducive to the environment and conducive to conservation purposes, then the pollution caused by them will not be overlooked.

The composition of the cartridge After the initial dismantling of the drum can be a photosensitive drum, plastic cover, gear, magnetic coats, magnetic rods, plastic rings, scraper, shaft, screws, springs, pins and plastic shell (including powder and waste Warehouse) and other components. The material composition of the cartridge includes plastic, iron, magnetic, aluminum, copper, soft material and toner. 2.2 The composition of toner composition Toner is made of resin, carbon black, magnetic oxide, lubricants and other materials synthesis of a mixture (see Figure 1), at room temperature is more stable, the surface size is relatively uniform fine particles, Light weight, difficult to dissolve in water, chemical stability. By scanning electron microscopy (SEM) magnification observation, you can more clearly see that the toner particle size is more uniform, spherical particles, particle size between about 3-7μm.
