How to create smokeless energy from old tires? The secret fuel for cement plants!
Globally, the recycling of old tires has become an important environmental issue. As the number of cars increases, the amount of used tires generated is also increasing. According to statistics, there were more than 1 billion waste tires piled up in the United States in 1990. These durable and difficult-to-degrade wastes put tremendous pressure on the environment. Among them, cement plants' use of old tires as fuel is an obvious solution.
It is estimated that from 1994 to 2010, the annual recycling of tires in the EU increased from 25% to nearly 95%, of which nearly half of the tires were used as a source of energy.
Used tires can be used as an alternative fuel in the cement manufacturing process, heating them to high temperatures of 1000 to 1200 degrees Celsius for almost instantaneous complete combustion. This process not only effectively utilizes waste, but also reduces greenhouse gas emissions.
Use of tires in cement production
Old tires are put into cement kilns whole or cut into small pieces of 5 to 10 mm and burned. The production of cement requires a certain amount of iron, and the iron in the steel bar can help in this process. This utilization method not only reduces production costs, but also further solves the problem of waste tires.
Overall, the combustion of waste tires is smokeless and can produce relatively clean energy, and is one of the indispensable ingredients in cement production.
Environmental impact and future directions
Although tire burning has its environmental potential, it has also raised concerns about environmental pollution. Especially in the case of incomplete combustion of the tire, harmful emissions may be produced. Therefore, how to technically improve the efficiency of the combustion process will be a challenge in the future.
In addition to playing a role in cement production, old tires can also be converted into fuel oil or natural gas through new technologies such as thermal cracking, which provides new ideas for the management and recycling of old tires. To some extent, the treatment of old tires is no longer just disposal, but a renewable resource.
Social responsibility and circular economy
Against this background, relevant enterprises have also begun to assume social responsibilities. Promoting the recycling and utilization of tires can not only promote the development of the green economy, but also guide consumers to develop environmentally friendly habits. Through education and publicity, promoting the concept of "waste management with waste" will effectively reduce the environmental burden.
Through continuous innovation and technological advancement, the recycling of old tires will become one of the necessary options for cement production, giving us new hope for environmental protection.
For example, many regions are using improved recycling methods, such as liquefaction-to-gasification technology, to convert old tires into heat and other reusable materials, creating fascinating potential for more business opportunities.
ConclusionAs the concept of environmental protection becomes more popular, the technology of using old tires to produce smokeless energy is not only the future development direction of the cement industry, but also an important step in the world's pursuit of circular economy and sustainable development. In this case, can we make better use of old tires as a resource to achieve a more environmentally friendly future?
