Organic wet fraction seperation plant - Omrin
Omrin is a collector and processor of waste, handling waste collection for 173,000 households in 16 municipalities in and around the provinces of Friesland and Groningen, and for almost 7,000 companies. They also process the waste for approximately 800,000 households and many businesses. They are doing their utmost to recover as much raw material as possible from waste to produce renewable energy.
In 2015, a new plant for Wet Organic Fraction (WOF) was delivered. This installation separates inert material, and the purified WOF is used for the production of biogas in a digester. The separation takes place by means of a sieve, and then an x-tract that separates the inert material in the WOF with the aid of X-rays.
No interfering substances anymore in WOF
Bart-Jan van Dixhoorn manages projects and operations at Omrin, where he works closely with Banzo. “We have our ideas on how such a system should work, but we need the expertise of Banzo in order to translate our ideas into drawings and technical solutions. You can think of something, but it must also be able to be built and operated. The ability to translate ideas to the creation of something and install it for us is the added value that Banzo provides.”
What factors play a role in the company’s decision to work with Banzo? “Maximum recycling efficiency, minimum human work, robust installation safety. There’s engineering needed to translate that into a steel structure, to fit in the equipment, etc.”
“The goal we have with the WOF installation is to retrieve all disruptors. In the input is 15% pebbles, all of which must be removed by at the end of the process. The plant processes 15 tons per hour, which is 1.5 to 2 tons of stone per hour. It has its value as a raw material, and with these disruptors removed the fermentation of the WOF is able to proceed more efficiently.”
“With our approach, we are able to make 65 percent of the waste we collect suitable for reuse.”
In 2016, Banzo worked with Omrin on a sorting plant. “Our collaboration is actually continuous, and Banzo is one of our permanent partners. Together we work on our mission to finally have 100% of the waste be converted into raw materials.”
