MRF Process is a waste management technique that focuses more on recycling rather than the elimination of waste. The main purpose is to conserve resources by optimizing their use. Reuse of resources promotes sustainability because our limited resources are consumed more slowly hence depletion which is considered inevitable is delayed. This salvaging method is considered to be better than landfills that simply gather solid waste and pile them up in dumpsites. Dumpsites have also been proven to lengthen the life of garbage because when the trash gets covered with layers of soil and other waste the access of oxygen to it becomes limited which greatly slows down decomposition and degradation.

MRF Process starts the same way as the landfill system. Garbage bins are distributed to households or placed in key areas so people can place their trash in them. Trucks will then collect the garbage and bring it to the recycling facility. The waste is then subjected to a mix of mechanical and manual sorting sessions to segregate it into its different components. The biodegradable component is separated and turned into fertilizer. The non-biodegradable component on the other hand is readied to undergo the final treatment sessions. One can notice that there are substantially more steps involved here than in landfilling. The said additional steps also entail additional costs.

The final phase of the MRF Process is sorting of the materials to their specific groups and subjected to final treatment to make them resalable. The common waste groups are plastic bottles, tin cans, glass containers, and aluminums. The groups are then placed on containers which are then taken to shipping boats. The shipping boats then deliver them to the end users. Sometimes the original manufacturers themselves are the once to purchase the reusable materials. A plan is termed to be a clean type if it deals with pre-sorted trash and a dirty type if it deals with raw garbage. A wet type is one which adds water cleansing to the process.

The normal waste-to-reusable conversion rate of the MRF Process is 75%. This means that only a quarter of the waste is taken into dumpsites and the other three quarters is once again used for production. This also equates to saving three fourths of the needed resources which in turn benefits sustainability. This recycling scheme is expected to replace landfills all over the world. Research and development is still ongoing with high hopes of further increasing the conversion rate. In the near future, garbage in landfills themselves will be subjected to the recycling plants to significantly reduce the amount of waste present in our environment.
