Resource recovery is a vast, fast growing global market

17 June 2015

With the reality of diminishing natural resources and mounting landfill and electronic scrap issues worldwide, on-going efforts are being made to source alterna­tives to raw materials and develop new approaches to utilise end-of-life products. New ideas are identified every day to recycle or reuse plastics and other materials contained within the disposable products we don’t think twice about replacing. And so the cycle continues…

STEINERT’s goal is to provide resource recovery processing operations with efficient solutions to produce clean, market-ready end-products. The decisive factor is having a range of solutions that encompasses perfectly tuned technologies capable of separating materials that previously could only be extracted with difficulty - or not at all. Herein lies the potential for profit…  

STEINERT continues to develop new and enhance existing sorting and separation technologies in response to the demands of the global resource recovery sector, offering a wide portfolio of equipment for a range of industries throughout this sector such as Municipal Solid Wastes, Process Engineered Fuel and Waste to Energy for some examples.  

Municipal Solid Wastes (MSW) provide an easy-to-access source of valuable materials, mostly in forms ready for processing - including iron, copper, aluminium, glass, paper and plastics. In the event that recovery is not feasible from an economic or technical point of view, they can still be used as a source of Process Engineered Fuel (PEF) as a CO² neutral alternative to fossil fuels. Success is made easy by utilising innovative sorting technologies from STEINERT to recover the valuable materials hidden in refuse brings ecological and economic leadership.  

PEF is produced by shredding and dehydrating MSW using separation technologies from STEINERT such as magnetic separation and sensor-based sorting equipment. The residual material can be sold in its processed form (depending on the process treatment) or it may be compressed into pellets, bricks or logs and used for other purposes.   The resulting PEF consists largely of the high-calorific, combustible components of municipal waste such as plastics and biodegradable waste which can be used in Waste-to-Energy (WTE) facilities to produce clean, renewable energy.   Such considerations are the main reason why several countries administrate WTE of the biomass component of waste as renewable energy. The rest—mainly plastics and other oil and gas derived products—is generally treated as non-renewables.

UniSort -  the smart sorting solution  

The UniSort range from STEINERT RTT is built specifically for this sector. Utilising a range of detection and separation technologies, the UniSort line of machines automatically sort waste at different points along the recovery and recycling path.   With the innovative sensor-based sorting solutions - the UniSort Black Scan, recognises and sorts dark fragments off the spectrum in order to add them to the recycling cycle later on. As a result, the residual fraction to be disposed of is minimised, significantly reducing disposal costs.

There are many links in a successful recycling chain, and materials-sorting is an increasingly important one. The UniSort PR sorts large items such as whole soft drink bottles to achieve a high level of purity. Recycling facilities utilising the UniSort PR can increase both their throughput and the purity of their recovered materials, assisting in the creation of higher value recycled products.   Increasingly, customers are demanding continuous real-time analysis of the materials being used in the production of substitute fuels (SF) for thermal recovery.

The UniSort Analyser, in conjunction with the UniSort PR is a base for efficient quality management for substitute fuels.   Usually, the analysed samples only reflect the nature of the samples themselves, furthermore, the analyses cannot be accessed and utilised within a short time of the samples being taken. The UniSort Analyser’s real-time analysis offers a solution for continuous, real-time quality control using HSI technology.    

The latest addition the smart sensor-based sorting range - UniSort Film - is specifically designed to combat the previously unresolved issues film presents to sorting throughout the resource recovery process.

Improved magnetic separation solutions  

Continuous updates to proven magnetic separation equipment in response to market requirements is something STEINERT is renowned for. The traditional and trusted machines, such as the STEINERT NES (Eddy Current Separator) which collects non-ferrous metals (used when recycling aluminum, shredder material, and household waste) remain part of the core product offerings of the company. This machine has recently been further developed into the high frequency model of the NES 4T, especially suitable for use with fine-grained materials and slag. The heart of the separation system is a turning pole drum with a field frequency of around 1 kHz. With this new process, output can be increased by 20%-30%.  

Tradition + innovation  

From traditional and trusted magnetic separation equipment, right through to innovative sensor sorting technologies, we help our customers achieve their goals with sustainable solutions.  Whether that is to improve profitability, to reduce operating costs, or to improve product purity and even limit environmental impact from their operations - we understand the diverse needs and unique regional necessities which our customers have to deal with. This enables STEINERT to deliver 'value-added' solutions from design and consultation through to manufacturing, installation and commissioning services.   And STEINERT service doesn't end when your equipment is delivered - it marks the beginning of a reliable partnership for your long-term benefit.
