The population growth that we have increases the production of waste materials on earth. Though there are different waste management processes that have been conducted to minimize our waste still, it grows every day. Landfills are now being subject for disapproval by environmentalist and the residents who will be greatly affected in building of dump sites in their area. Since having landfills in the area can be a cause of health issues and pollution that will greatly affect the environment and population. Recycling facilities are being created to solve the landfill concern that we have nowadays. The recycling facility are responsible for receiving, separating and preparing recyclable waste materials that will be used to produce a new product or selling it to manufacturers. But even if there is a recycling facility, landfill can still be useful because that is where the waste materials are stocked. There are different kinds of recycling facility but clean and dry facility is generally used to distinguish the types of waste materials. Wet recycling facility is also being utilized nowadays for specific wet or liquid types of waste material.
Clean recycling facility is the composition of waste materials that are already separated from the municipal solid waste before it reaches the facility. The waste materials are already sorted according to certain specification and processed accordingly. The process may include shredding, drying crushing, compacting and preparing for shipment to the market. Dirty recycling facility on the other hand, is the facility that accepts mixed waste materials. After receiving the mixed waste material, it is being separated and segregated to its different types through mechanical or manual sorting. The sorted waste materials that can be recycled will undergo the processing procedure and the other mixed waste materials will be disposed to a different kind of facility such as landfill. Dirty recycling facility can be a great challenge since it requires more labor and expensive than having a clean recycling facility. Though having a dirty recycling facility provides higher recovery rates than a clean recycling facility since it can recover more waste materials that can be recyclable. Compared to a clean recycling facility, the sorting process is already conducted from the source of the waste material whereas in a dirty recycling facility, they are the ones who also do the sorting process to which, they can have a greater control in selecting the waste materials that can be recycled or sell to the market.
