GIVING SLURRY TREATMENT PLANTS A NEW LIFE CYCLE
To support improving economic and sustainability outcomes on slurry shield tunnelling projects, the benefits to be gained from refurbishment of slurry treatment plant are discussed by Gino Vogt, Head of Herrenknecht Separations
The emotional highlight of a tunnelling project is the final breakthrough. But work usually recommences immediately following breakthrough festivity as many tasks seamlessly follow until a project finally completed. In many cases, equipment is bought back by the
supplier. Processes such as inspections, buyback agreement, disassembly, return transport are essential to complete a project holistically. Afterwards, equipment in stock is available for re-use in the next project. Whether tunnel boring machines (TBMs) or additional equipment, these steps are crucial for the success of the entire project. From manufacturer Herrenknecht’s point of view,
the following article focuses in more detail on the best practice process for refurbishment of one of the most important of the additional equipment necessary on a jobsite performing slurry operated mechanised tunnelling – the Slurry Treatment Plant (STP).
REFURBISHED PRODUCTS IN THE CIRCULAR ECONOMY The concept of a circular economy is based on the idea of creating a restorative and regenerative economic system that maximises the value and utility of products, components, and materials throughout their lifecycle. It involves a fundamental shift in our consumption patterns towards more sustainable practices, making it a crucial factor in achieving a sustainable future. One of the most significant aspects of this approach
is the refurbishment of products. By giving products a second life, we reduce waste and conserve resources. Refurbishment has benefits, both environmentally and economically. It enables the extension of the useful life of products, it reduces the need for raw materials and energy consumption, and it can provide more affordable options for consumers.
