Breathing new Life into RDF and SRF

As the war in Europe continues, the pressing matter of identifying energy alternatives is soaring. A trend in the waste management market seems to indicate that the waste materials RDF (Refused Derived Fuel) and SRF (Solid Recovered Fuel) are making a comeback.

RDF and SRF are terms used when referring to processed waste for use in WtE (waste-to-energy) facilities or cement kilns for energy generation. Generally, the two materials are distinguished based on the amount of processing: SRF has undergone additional processing, leaving the material a higher and more consistent calorific value than RDF, ideal for use in incineration to reduce the amount of build-up and furnace downtime.

Orkel is experiencing a rise in the number of RDF and SRF inquiries. The questions often revolve around the bale-ability of these materials as plant managers seem to seek out efficient ways of transporting fluffy material.

Ideally, a method to ensure simplified storage and cost-efficient transport to maximize the profitability of RDF and SRF should be applied. Through comprehensive development processes, Orkel’s engineers found that high-density baling technology provides the sought-after characteristics of efficient storage and transport, assuming that the machine is specialized in handling small-fragmented material to prevent flyaway. Additionally, applying Orkel Telematics technology allows the customer to effortlessly scan each bale’s tag and view its content and place of origin. As a result, the high-density round bale is easy to label and sell independently, assuring that a WtE facility can purchase the required material to keep the operations running.

Despite the logistical challenges, it is exciting to witness how the waste management industry is breathing new life into waste materials due to the rising oil prices.
