With the development of modern industry, the global energy crisis and environmental pollution issues have become increasingly acute. The world is actively seeking new renewable energy sources to ensure long-term sustainable development, and photovoltaic technology represents one of the significant outcomes in this endeavor. However, the widespread adoption and deployment of photovoltaic technology also signifies that the recycling and reuse of end-of-life photovoltaic cell panels has become imperative. Photovoltaic cells recycling not only meets environmental protection requirements, but also effectively extracts valuable materials such as silicon, glass, and aluminum. At present, Europe (Germany, France), North America (the United States, Canada), and Australia have established relatively complete photovoltaic cell panels recycling systems. Therefore, setting up a photovoltaic cells recycling plant is highly feasible and it is a sound choice with promising development pr...

For enterprises planning to invest in biomass pyrolysis projects, it is crucial to understand the size and reasonable layout of the space required to build a biomass pyrolysis plant. The space planning in the construction of the plant directly affects the production efficiency and operating costs. The space required for biomass pyrolysis plants of different sizes varies greatly from 500-2000+㎡, and it is necessary to comprehensively consider multiple factors such as the scale of plant operation, the type of equipment used, and the requirements for raw material processing. Biomass pyrolysis plant scale The production scale is the core parameter that determines the biomass pyrolysis plant space. A small or medium-sized biomass pyrolysis carbonization plant with a daily processing capacity of 5-10 tons may only need 500-1000 square meters, while a large industrial-scale production line with a daily processing capacity of more than 50 tons may require more than 1500 square met...

The demand for high-quality biochar is surging, thanks to its key role in sustainable agriculture (soil improvement, carbon sequestration), renewable energy and advanced filtration technology. For companies ready to take advantage of this growth opportunity, efficient and sustainable production scale is essential. Biochar is a solid product formed by heating biomass in the absence of oxygen through pyrolysis technology. This process not only retains the carbon element in the raw material, but also forms a porous structure, which gives biochar good adsorption properties and water holding capacity. Common raw materials that can be used to produce biochar include various organic wastes such as wood chips, crop straw, fruit shells, livestock and poultry manure, etc.  Biomass to biochar via pyrolysis technology Traditional kiln production Earth kilns and brick kilns are more traditional biochar production machine, suitable for small-scale production. This type of equipment...

With the rapid development of new energy technology, lithium batteries are increasingly used as an important component of electric vehicles, portable electronic devices and energy storage systems.

Composition and potential value of scrap lithium batteries Waste lithium batteries contain a variety of valuable metal materials, including lithium, cobalt, nickel, aluminum, etc. These metal materials have a wide range of application needs in the fields of electronic product manufacturing, new energy industry, etc. Through professional lithium battery recycling plant, these valuable components can be effectively separated and extracted to achieve secondary utilization of resources. Valuable metals extracted from scrap lithium batteries ...

With the rapid development of the solar energy industry, a large number of installed solar panels are gradually reaching the end of their service life. According to data, the average service life of solar panels is 25 to 30 years. As more solar panels enter the end of their life cycle, how to effectively deal with these waste solar panels has become a key issue of concern to the industry. Solar panels contain glass, aluminum frames, silicon wafers and valuable metal materials, which can be recycled through professional recycling. Discarded solar panels that are not properly handled may have potential impacts on the environment, and standardized recycling processes can not only reduce resource waste, but also create new economic value. Reuse and recycling process of solar panels 1. Preliminary processing: After the old solar panels are recycled to the factory, the first thing to do is physical disassembly. Through professional equipment, the metal frame, glass and other rec...

Vegetables, fruits and other kitchen waste can be processed by carbonization technology and converted into biochar. This type of organic waste contains rich cellulose and lignin components, and can complete pyrolysis reactions under appropriate temperature conditions. The carbonization process can convert organic matter in kitchen waste into stable carbonaceous materials. This process belongs to thermochemical conversion technology. This conversion not only solves the problem of waste disposal, reduces environmental problems caused by landfill or incineration, but also obtains valuable biochar products. Pyrolysis refers to the process of thermally decomposing organic matter in an oxygen-deficient environment by heating (usually at a temperature of 300~700℃) to generate solid carbon (biochar), combustible gas and liquid products. The following is a detailed introduction to the key steps of kitchen waste carbonization. 1. Pretreatment First, the kitchen waste should be crus...

As an environmentally friendly fuel, charcoal plays an important role in agricultural improvement, energy utilization and environmental protection. If you are considering entering the field of charcoal production, understanding the professional machine required is the first step to success. Several types of machine are usually needed to produce charcoal. These include raw material preparation machine (such as crusher and dryer), carbonization machine (such as carbonization furnace or carbonization kiln), auxiliary equipment (such as conveyor, screening machine and packaging machine), and environmental protection machine (such as dust removal equipment and exhaust gas treatment facilities). The choice of specific equipment depends on the production scale, raw materials and process flow. The following will give you a detailed introduction to the machines usually required to make charcoal.  Machines needed...

In recent years, the popularity of electric vehicles, electronic products and energy storage systems has led to a surge in demand for lithium batteries. But at the same time, the number of discarded lithium batteries has also increased year by year. With the strict implementation of environmental regulations and the increasing shortage of battery resources, the importance of lithium battery recycling has become increasingly apparent. Environmental and economic value of lithium battery recycling Recycling scrap lithium batteries can not only reduce pollution to the environment, but also extract valuable metals such as lithium, cobalt, nickel, etc., which have important applications in the new energy industry. Therefore, lithium battery recycling not only has environmental value, but also considerable economic benefits. The profitability of lithium battery recycling mainly comes from the following aspects: 1. Recycling valuable materials Waste lithium batteries contain a vari...
