We have a well-received tire shredder in Saudi Arabia, this tire shredder is a GDT model double-shaft tire shredder running for more than two years. In this project, the waste tires are crushed and sorted by the tire shredder, and then directly enter the tire cracking and oil refining series equipment to decompose the waste tires into steel wire, carbon black and fuel oil, which not only solves black pollution, but also creates a huge economy income!How does the tire shredder in Saudi Arabia work?After the waste tires are drawn by the tire wire drawing machine, the thicker steel wires on both sides of the hub are extracted, and the wire-drawn tires are transported into the crushing bin of the tire shredder through a heavy-duty metal chain conveyor. The rotor in the knife box is driven by a motor + a reducer. The tires are crushed and cut into pieces, and the outside of the equipment is surrounded by a ring drum screen. The tire rubber blocks cut into small pieces fall on the roller screen, and the rubber

How many plastic bottles do you discard in a year? How are various plastic bottles recycled?Firstly, sort plastic bottles based on different materials and remove debris; Secondly, place the sorted plastic bottles of the same type into the soaking pool, soften the labels on the bottle body with the soaking solution, and remove them; Then, place the plastic bottle with the label removed into a grinder for crushing treatment; Once again, feed the plastic bottle fragments into the air separation equipment and remove the remaining label fragments from the plastic bottle fragments by blowing air; Next, the plastic bottle fragments are fed into a separation tank, and the bottle body fragments and bottle cap fragments are separated by a separation solution based on the different densities of the bottle body and bottle cap; Finally, the separated bottle fragments are steamed, disinfected, and dried.As an environmental expert who has been working in the waste plastic bottle recycling industry for several years, I have

With the rapid development of China's urbanization process and municipal infrastructure construction, as well as the renovation of old residential areas and factories, demolition and renovation of urban villages and other projects, the production of construction waste in China has increased year by year. According to statistics, the production of construction waste in 2021 has reached 3.209 billion tons. Therefore, the national policy has been advocating the reduction and resource treatment of construction waste, which is of great significance to save resources and protect the environment.We all know that construction waste through crushing, sorting and other links can finally get valuable sand and stone aggregate, metal and some fuel, sand and stone aggregate can be used to make concrete for the construction of buildings, roads, Bridges and other construction, metal can be sold, light fuel can be incinerated for power generation, garbage is misplaced resources can be said to be reflected incisively and

With the rapid development of science and technology, the frequency of updating electronic products is accelerating, followed by the increasing number of electronic waste and the aggravation of the environmental burden. The renewable resources available in electronic waste include steel, nonferrous metals, plastics, and of course, there are also toxic and harmful substances, such as lead in welding, cadmium in resistors/semiconductors, mercury in printed circuit boards (PCBs), chromium in metal coatings, lead/mercury/cadmium in batteries, and beryllium in motherboards. How to treat them innocuously and as resources is a difficult problem that needs to be solved urgently.GEP's electronic waste disposal production line can effectively solve such problems. The electronic waste is first broken and separated using a dedicated shredder for electronic waste, and then separated by an magnetic separator and eddy current separator. Plastic and different types of metals are transported to different areas, where useful

Medical waste refers to waste generated by medical institutions in medical, preventive, health care, and other related activities that has direct or indirect infectivity, toxicity, and other hazards, specifically including infectious, pathological, injurious, pharmaceutical, and chemical waste, such as used cotton balls, gauze, tape, wastewater, disposable medical devices, postoperative waste, expired drugs, and so on. If medical waste is not managed and allowed to flow into nature, it will affect the ecological environment, cause the spread of epidemics, and threaten the safety of public life. Therefore, the entire process of generating, classifying, packaging, collecting, transporting, storing, and disposing medical waste must be under strict control, especially through safe disposal. Currently, the treatment methods for medical waste include rotary kiln incineration, pyrolysis incineration, high-temperature steam, microwave disinfection, chemical disinfection, sanitary landfill, etc. Direct filling and

Petroleum sludge is an oily solid waste generated during oil field drilling, transportation, refining, and oil wastewater treatment. Petroleum sludge contains a large amount of malodor, pathogenic bacteria, parasites, harmful chemical heavy metals such as copper, zinc, chromium, and zinc that exceed the standard. If not effectively and timely treated, it will cause serious harm and corrosion to the surrounding crops, soil cultivation, water, air, and ecological environment.Currently, the treatment technologies for petroleum sludge mainly include pyrolysis, incineration, landfilling, solvent extraction, biological treatment, etc. There are common problems such as small scope of application, high treatment costs, widespread illegal landfilling, and non-standard emissions, which cannot adapt to the objective situation of wide sources of petroleum sludge, complex components, and low charging standards.GEP has rich experience and mature equipment in petroleum sludge crushing and disposal.

The first way is to smash and discharge directly. Due to the limited kitchen space, on-site reduction treatment is the basic foothold of kitchen waste treatment. Some countries have equipped kitchen waste crushing equipment in the kitchens of units with small amount of kitchen waste to discharge the crushed waste into the municipal sewage pipe network. Of course, clogged drainage pipes and breeding of mosquitoes and flies are the disadvantages of this method.The second way is landfilling, which is the common way for all kinds of garbage disposal. The kitchen waste contains a large number of degradable components, which is conducive to the recovery and use of the landfill site, and the operation is simple, so it is relatively common. However, with the gradual promotion of the availability of kitchen waste, the way of landfill has shown a downward trend, and even some countries have banned this way.The third way, fertilizer treatment, mainly includes aerobic composting and anaerobic digestion. Aerobic
