Industrial production will produce a lot of waste, along with the development of our country economy, industrial waste more and more, along with the development of national environmental protection, industrial solid waste must be properly treated, under the background of "no waste city", the treatment requirements of the industrial solid waste is higher, not only harmless treatment, at the same time must carry out resources utilization. General industrial solid waste in the narrow sense, we usually refer to the leather scraps or waste spinning scraps from clothing and footwear factories, as well as the light slag or twisted rope produced by paper mills. In fact, these raw materials have a high calorific value and high resource utilization value. They can usually be broken into small sizes or made into RDF fuel rods and sold to power plants or cement plants. In this way, industrial solid waste disposal enterprises have a part of profits when receiving raw materials and another part of profits when selling

Biomass resources mainly consist of various types of residues and waste (passive biomass resources), including agricultural waste, forestry waste, livestock manure, household waste, sewage sludge, etc. The utilization of biomass energy is mainly concentrated in the application of electricity production, including agricultural and forestry biomass power generation, garbage incineration power generation, pyrolysis gasification power generation, and biogas power generation. Taking agricultural and forestry biomass as an example, when used for power generation, its carbon emission intensity is only 1.8%, 2.1%, and 3.8% of that of coal, fuel, and gas. Therefore, reasonable and full utilization of biomass energy can not only achieve harmless, reduced, and resourceful utilization of various organic waste, thereby improving the ecological environment, but also contribute to reducing fossil energy consumption, improving energy utilization structure, and reducing greenhouse gas emissions.GEP is a long-term enterprise

Car owners, when you are about to eliminate your car's tires, don't throw them away casually. Instead, sell them to a professional waste tire recycling store to avoid wasting valuable resources. Why do you say that? Firstly, tires that are not severely worn can be reused. Tyres with incomplete wear and tear on the main body can be peeled off, glued with rubber, and re vulcanized to make retreaded tires. The raw material consumption of refurbished tires is very low, and the price is relatively cheap, with a high cost-effectiveness. Moreover, experts say that the performance of refurbished tires does not differ significantly from that of new tires at safe driving speeds.Secondly, the tire itself is a very complex compound, so after crushing and cracking treatment, the tire can obtain raw materials such as carbon black, tire oil, and steel wire. Tire oil can be directly burned or refined to obtain gasoline and diesel; Carbon black can be used for manufacturing inks, paints, etc; Steel wire can be used directly

The amount of RDF (Refuse-Derived Fuel) that can be produced from one ton of household waste can vary depending on several factors, such as the composition of the waste, the efficiency of the RDF production process, and the technology used for RDF production.Generally, it is estimated that one ton of household waste can produce around 150-250 kg of RDF. However, it should be noted that this is just an average estimate based on preliminary sorting of the waste to remove recyclable materials.The composition of householdwaste can vary depending on several factors, such as locality, time of the year, etc. household waste is composed of organic and inorganic matter, plastics, paper, and other materials. These materials differ in their calorific value, meaning their energy content per unit mass. Consequently, it is important to understand that the amount of RDF produced from one ton of domestic waste depends on the composition and quality of the waste stream.Another factor to consider is the RDF production

What is dry waste?Dry waste refers to other household waste, excluding recyclable waste, harmful waste, and wet waste. This includes discarded paper, plastic, glass, metal, fabrics, hard fruit shells, rubber putty, adhesive products, as well as large garbage such as scrapped vehicles, household appliances and furniture, and decoration waste. Dry waste can be used as fuel and raw materials for resource utilization after crushing treatment.Disposal process of dry wasteDry waste is transported by a chain plate conveyor to a pre-shredder for bag breaking. The shredded material is then removed by an magnetic separator and enters the rotary drum screen, which is then flipped and rolled along with the drum device. Unqualified materials are discharged through the end of the drum, and qualified materials are discharged onto the output belt through the outer circular screen of the drum. The belt enters the wind sifter, achieving the separation of light and heavy substances under the action of the airflow, Finally, the
