NRAs 2019: Recycling Excellence – Large Organisations

WINNER: Multiplex Construction Europe, Protec International and Lindner Facades

Multiplex, Protec and Lindner collaborated across the construction supply chain to transform more than 10,000 temporary polypropylene (PP) protection sheets weighing 7.2 tonnes into a usable material on the Principal Tower project in London.

The scheme showed the importance of collaboration on building projects between the principal contractor (Multiplex), subcontractor (Lindner) and supplier (Protec). By agreeing such a strategy, the waste targets of each business were achieved.

JUDGES’ COMMENT: “This is a great project to shine a light on for others in the sector. It demonstrates how a collaborative approach to a specific problem has led to a closed loop solution that can be rolled out and implemented more widely.”

The Proplex closed loop recycling scheme was developed and implemented by Protec to remove plastic sheets from construction sites. The waste is diverted and fed into a manufacturing plant as feedstock, where it is shredded, washed, dried and granulated into PP pellets. The pellets were extruded into Proplex sheeting and returned to Principal Tower, where it was reused and available to go back into the recycling scheme.

Since the scheme was implemented on Principal Tower, Multiplex has promoted it across all sites as well as its central procurement department. Protec is now working with the department to roll out the scheme across Multiplex sites for various trades, not just facades. Lindner is also looking to adopt this initiative on its projects.

The success of the scheme at Principal Tower has enabled all three companies to endorse closed loop recycling of temporary protection on more sites. As a result, a further 12 construction sites implemented the scheme in 2018, recycling more than 107 tonnes of plastic.

As well as cutting the amount of waste generated on the Principal Tower project, the scheme also educated the workforce across three levels of the supply chain on the concept of closed loop systems and the importance of recycling waste.
