Refuse-derived fuel (RDF), A Safe Waste Solution

In our everyday lives, we always encounter trash. It is everywhere and present in everything that we do. There are a lot of ways that we can do to manage our waste. It can start in as simple as avoiding to have trash or using recyclable materials so we can lessen our garbage. Landfill is one of the most commonly used waste management method that is being done in most countries. But nowadays, we are encountering issues with regards to excessive and lack of location for landfills.

One solution that is being done for this is turning waste into energy. It is a waste management process wherein waste are being recovered to produce energy that can be used for electricity and create fuel. Although incineration is considered as one of the oldest and effective way to eliminate waste, studies says that it has negative impacts to the environment. Since incineration has a process includes releasing of ashes and flue gases, it is considered as harmful to mankind. That is why, waste to energy emerged which uses the gasification process that is pollution free and safe for the environment.

Refuse-derived fuel (RDF) is one of the products being produced in the gasification process. The process involves the shedding and drying of waste materials that are being processed to produce refused-derived fuel. It mainly includes bottles and biodegradable waste materials that had been separated from other harmful trash like metal.

Refuse-derived fuel (RDF) can also be fired with other kinds of fuel in different types of industrial boilers. It has been called out that the process for RDF can cause explosion, that is why it segregation of waste materials is crucial in the process to avoid serious damage.

Refuse-derived fuel has low-level of heavy metals since it is mainly composed of biodegradable waste products. If RDF has been densified, it can even be stored for longer periods compared with other kinds of fuel. But the coarse type of refused-derived fuel needs to be used for direct on-site and thus, can’t be stored like the densified type.

There could be a competition with other fuels on the market but thinking that this kind of fuel is not just a fuel but will also help in lessening our waste, it should be given more priority. It will be one way for us to help solve our waste problems and thus, making good use of it as part of our everyday lives.
