A Material Recovery Facility (MRF) sorts and processes different types of waste such as paper, plastics, metal, and glass which are further processed and sold to manufacturers. First, the waste is collected from households and businesses, and transported to the transfer station (MRF) where it is sorted and separated. Then, the non-recyclables such as inerts and debris are manually removed. Further, the remaining waste is sorted into categories with a combination of mechanical and manual methods. For example, paper and cardboard may be sorted using air classifiers, which use a stream of air to separate the materials based on their weight and size. Plastics, on the other hand, may be sorted using optical scanners, which use sensors to identify the type of plastic and sort it accordingly. Following this, remaining contaminants, like any food or liquid residue from containers, are removed. Finally, once the materials have been cleaned and processed, they are then baled and sent to manufacturers to be used in the production of new products. This process is crucial to the recycling industry as it allows for the materials to be reused and repurposed, rather than being sent to a landfill.
Overall, the process of sorting and separating materials at an MRF plant is a complex and multi-step process that requires skilled, semi-skilled as well as unskilled workforce, advanced technology, and a commitment to protecting the environment. With the increasing demand for recycled materials and resources, MRFs will play an increasingly important role in the recycling industry and in the efforts to reduce waste and protect the environment.
