Introducing a Novel Concept for an Integrated Demolition Waste Recycling Center and the Establishment of a Stakeholder Network: A Case Study from Germany

Zabek, M. (author), Jegen, Pauline (author), Kreiss, Lillith (author)

Using recycled aggregates has many positive environmental impacts because of the conservation of natural resources and minimization of waste. The use of recycled aggregates in downcycling processes is already common in Germany, whereas utilizing them to produce high-quality recycled concrete is rarely applied in practice. The reasons behind this...

Life cycle assessment of material footprint in recycling: A case of concrete recycling

Zhang, Chunbo (author), Hu, Mingming (author), van der Meide, Marc (author), Di Maio, F. (author), Yang, Xining (author), Gao, Xiaofeng (author), Li, Kai (author), Zhao, Hailong (author), Li, Chen (author)

Meeting the current demand for concrete requires not only mining tons of gravel and sand, but also burning large amounts of fossil fuel resources in cement kilning. Consequently, concrete recycling is crucial to achieving a material-efficient society, especially with the application of various categories of concrete and the goal of phasing...

An overview of the waste hierarchy framework for analyzing the circularity in construction and demolition waste management in Europe

Zhang, Chunbo (author), Hu, Mingming (author), Di Maio, F. (author), Sprecher, Benjamin (author), Yang, Xining (author), Tukker, Arnold (author)

The construction sector is the biggest driver of resource consumption and waste generation in Europe. The European Union (EU) is making efforts to move from its traditional linear resource and waste management system in the construction sector to a level of high circularity. Based on the theory of circular economy, a new paradigm called waste...

Experimental investigation of concrete mixtures incorporating recycled concrete aggregates

Mylonas, Akis (author)

In the Netherlands, yearly 33 Mton new concrete (roughly 15 billion m3) is producewhile 12 Mton concrete waste becomes available. Recycling of the yearly 12 Mton concrete waste results in roughly 7 Mton coarse recycled concrete aggregate (CRCA) and 5 Mton fine recycled concrete aggregates (fRCA). Currently, fRCA is not used in structural...

Urban mining and buildings: A review of possibilities and limitations

Koutamanis, A. (author), van Reijn, B. (author), van Bueren, Ellen (author)

In recent years there has been growing interest in urban mining in buildings from various environmental and economic perspectives. Materials hidden in buildings are attractive alternatives to raw ones and building activities are responsible for a large share of urban waste in many societies. The paper presents an analysis of possibilities for...
