Sustainability Award GroenLinks for Rutte Groep Sustainability Award GroenLinks for Rutte Groep | RTV Zaanstreek
Published on November, 5th 2018 On the occasion of the Day of Sustainability, GroenLinks Zaanstad awarded the Sustainability Award to the Rutte Group yesterday, Wednesday 10 October.

It is for the ninth time that GroenLinks handed out the prize. The prize was awarded because of the Smart Liberator. A machine with which old concrete can be reused and which is still on the company premises in Amsterdam.

If this innovative technology is applied globally, this can result in a 9% CO2 reduction, according to the Rutte Groep. Three of these machines eventually arrive at Zaandam. They are powered by energy that comes from solar panels. The production process therefore also takes place in a sustainable manner.

At the moment, the Rutte Group is still located in Amsterdam Westpoort. The company has acquired a site in the Achtersluispolder. "Cross beacon will be the location for the Smart Liberator within one to two years", according to Cornelis Wals of the Rutte Groep. "You better!" GroenLinks party chairman Paul Laport joked, "otherwise you will have to hand in this Zaanse Sustainability Prize again."

fully electrical processing, for example in several Microwave ovens Microwave heating
Published on October, 5th 2018 Re-cementing pure cement hydrates from the SmartCrusher is mainly a matter of heating, and thus a matter of energy. Chemically speaking, hardly anything has changed over the years. From pure cement hydrates this can be done with 30% to 50% less energy compared to CaCO3 (Marl) and with at least 80 less CO2 in existing cement kilns.

In the case of fully electrical processing, for example in a number of Microwave furnaces, this can amount to almost CO2 free new cement! Several Microwave ovens then also form a Gridleveler to match supply and demand of wind and solar energy.

CyBe SmartCrusher bv and CyBe bv are discussing a cooperation based on “Cooperation without limitation”.
Published June 28, 2015 The underlying motivation for SmartCrusher bv is that, on its own, SmartCrusher bv can make the chain of “only” half of all the new concrete circular and, as a result, climate neutral (the prognosis for the quantity of new concrete required is roughly twice the projected quantity of concrete rubble being released). To accelerate closing the concrete cycle completely and reducing CO2 emissions in the process, a different way of concrete construction is required. This means that it must be possible in concrete construction to realise the same quality and quantity of constructions by using substantially less new concrete. As 3D concrete printing is in many respects one of the promising and innovative technologies to this end, SmartCrusher bv is keen to contribute to this.
