ORGANIC TROMMEL FINES

A Strategy For The Removal Of Biowaste From Trommel Fines

the challenge for MRF operators


An estimated 5 million tonnes of organic waste are sent to landfill each year in the form of Trommel Fines.

This represent more than 70% of the total biowaste disposed of to landfill and until now there hasn’t been a technology capable of separating out the organics from the inert material.

The OREX is a proven, robust and cost effective technology which will extract more than 90% of this organic material

how the orex PRESS SOLVES THE TROMMEL FINES PROBLEM

The OREX Press extracts the organics in Trommel using high pressure (280 bar). The organic component is liquefied, separating it from the non-organic material.

  • more than 90% of the organics are extracted from the fines
  • 20 tonnes of fines can be processed every hour (70,000 tpy per press)
  • the organic fraction contains ~40% total solids making it suitable for aD
  • The non-organic (dry fraction) can be used as rDF or disposed of at a lower tax rate
  • easily integrated into existing waste processing facilities
TROMMELS IN LANDFILL
7 million tonnes per year of Biowaste is sent to landfill, with about 5mty in Organic Trommel Fines.

Trommel Fines contain up to 40% grit/glass/stone etc. which makes them unsuitable for direct anaerobic digestion. OREX offers >90% Separation of the organics in Trommel fines.

>90% LANDFILL DIVERSION

anergia’s OREX Press extracts 90% of the organics in MSW using a high pressure ram. 

A single OREX processes up to 70,000 TPY of Organic Trommel Fines, with less than 1% of inert material such as grit, stones etc.

How the OREX Press Processes Trommel Fines from an MRF

Key Anaergia Technologies deployed – OREX Extrusion Press, CleanREX Dynamic Cyclone and FIBREPlate Hybrid Hollow Fibre/Flat Membrane MBR.

The AD digestate produced Is not PAS110 certified, but can be prepared for discharge to sewer using the FIBREPlate Hybrid MBR.

The unique Hybrid Hollow Fibre / Flat Membrane MBR Ultra-Filters the digestate, which has had its nitrogen content removed by Nitrification-Denitrification as shown below.
