Preserve, re-use, recycle
It isn’t simply the concrete that’s been upcycled. In total, 95% of the materials from the old WTC towers is being preserved, re-used or recycled, the prime example being the preservation of 65% of the old towers in the ground level, the foundations and the circulation cores. Over 1,000 tons of material will find a new life elsewhere. What cannot be preserved or re-used will go to recycling. Moreover, most of the new materials (95% of those used in the Flemish government’s offices) will be C2C-certified or equivalent.
ZIN is moreover designed with change in mind: it is adaptable and alterable to today’s needs as also tomorrow’s; each of its component parts (other than the floors and outer walls) can be dismantled with ease, meaning the base elements can be reused if needed without any great complication. The uniformly dimensioned outer walls are designed to accord with any type of use, be it residential, office or as an hotel.
“The ZIN project, and especially this new way of producing concrete, has positioned Befimmo as a pioneer in making the building sector greener. The fact of being a joint cooperation between private and public sectors is an important element in that. The Flemish government made a particular point of encouraging us to make these sustainability endeavours right from the dismantling stage, continuing through construction and to the project’s prospective commissioning,” says Jean-Philip Vroninks, Befimmo’s CEO.
“Both our ecological and our societal awareness are central strands in our decision-making – now and in the future. The Cradle to Cradle Silver certification earned under this project is evidence of our commitment and serves to give prominence to it,” adds Marie-Sophie Foucart, Concrete Operations Manager (Belgium and France).
“The real estate and construction industry is currently responsible for 40 % of global CO2 emissions. We are aware of this responsibility. Thanks to the recycling or circular approach, we can make our construction methods even more sustainable and efficient.” Raymund Trost, CEO CFE Contracting.
