Terrace made of bottom ash at FabCity campus

Last week our partner Struyk Verwo produced the first batch of pavement slabs containing UrbaniteTM, the new building material from AEB Amsterdam and Inashco. This is a one-off batch of tiles to be used for the construction of a terrace at FabCity. UrbaniteTM is the classic example of ‘urban mining’, the use of the city as a source of raw materials.

AEB and Inashco have given themselves the goal of extracting everything possible from waste. They have developed a unique, patented technology for the extraction of minerals (sand and gravel) from bottom ash. Bottom ash is the material remaining after combustion and consists mostly of minerals, but also iron (ferrous materials) and non-ferrous metals such as copper, lead and zinc. These technologies enable the extraction of metals, with the remaining minerals being re-processed for use as fully pH-neutral, broadly applicable building material. This material is suitable for use in the making of pavement slabs and kerbs. The brand name of this product is UrbaniteTM. In this way, AEB Amsterdam and Inashco use various innovative techniques to work towards a circular economy.

Educational and sustainable programme
FabCity is a temporary campus with 50 special pavilions dedicated to innovation and sustainability. This campus is part of the Europe by People programme, the educational, cultural and sustainable programme offered by the Netherlands within the framework of the European presidency. AEB and Inashco will construct the ‘Bottom Ash Terrace’ at the campus this week. It’s a good example of the circular economy in which raw materials are recovered and reused in a sustainable manner in the city.

On 11 April, FabCity will be formally opened by Mayor Van der Laan and from that moment the campus will be open to the public. Many European delegates will also visit FabCity.

About AEB Amsterdam
AEB is a sustainable raw materials and energy company in the metropolitan region of Amsterdam. AEB has been privatised since 2014, with the municipality of Amsterdam being the sole shareholder. AEB employs 400 people who work daily towards a clean society. Of the 1.4 million tons of waste that AEB processes annually, 99% is converted into raw materials and energy. AEB uses the heat released by the combustion of residual waste to generate electricity for 320,000 households and to warm homes and business premises through the growing city heating network.

Together with our partners we are working on solving waste problems. We share our knowledge and expertise in partnerships, both nationally and internationally. This has already led to many innovations, such as the technology for the High Efficiency Power Plant (Hoogrendement Centrale).
