During autumn and winter, there will also be more dead branches and fallen leaves on the ground. Although it can barely be considered a decoration of the urban environment, it does indeed add trouble to people's travel and sanitation workers' cleaning. These withered branches, fallen leaves, weeds, and flowers are collectively referred to as garden waste. Their characteristics are scattered, light weight, and large area, making collection, storage, and treatment more troublesome. Traditional landfilling and incineration methods have a significant impact on the environment, which is not advocated by environmentalists. Resource utilization has become a new trend.
Resource utilization requires the collected garden waste to be transported to a specialized disposal center for treatment. Stronger tree trunks, roots, and branches can be first shredded with a pre-shredder, greatly reducing their volume and size. Then, they can be sent together with fallen leaves and fine branches to a double-shaft shredder for further shredding. If finer discharge sizes are required, a fine shredder can be added for further refinement. In order to make the discharge more pure, sorting equipment such as a magnetic separator can be added between shredders.
To ensure the discharge is of high purity, sorting equipment like a magnetic separator can be added between shredders. Using this approach, thick branches with a diameter of over 5 cm can be used for papermaking and density board while tree roots can be directly used as raw materials for root carving. On the other hand, branches and leaves below 5cm can be shredded using a shredder and used for further production of organic fertilizer or biofuel, making the process of resource utilization environmentally friendly.
GEP has an extensive product library consisting of equipment tailor-fit for the optimum resource disposal process of garden waste, which includes pre-shredders, double-shaft shredders, fine shredders, and forming machines. To ensure production efficiency, GEP provides suitable equipment configuration plans and production line layouts based on the disposal center's site conditions. This enables the disposal center to ensure that they have the appropriate machinery for use with a smooth and effective production line.
Dead branches and fallen leaves contain essential elements like carbon, oxygen, nitrogen, and sulfur. Amongst these, carbon accounts for the highest proportion in the dry base of dead branches and fallen leaves, with a mass ratio of about 50%. Turning dead branches and fallen leaves into biofuels by processing them can store carbon elements, lowering the use of fossil fuels, and reducing air pollution. It becomes a “secret weapon” for effectively decreasing the overall carbon footprint.
