MDX Feeding System

DEM Aided Design of a Shredded Copper Cable Feeding System

Magnetic Density Separation (MDS) is a novel method for the separation of shredded complex wastes [7, 8]. It uses a magnetically induced density gradient in a ferrofluid, which allows particles with different densities to follow different trajectories. Small variations in feeding ...
Urbanization has significantly altered the built environment, leading to increased urban heat and the loss of green spaces, which are being replaced by buildings, which in its turn retain more heat inside the city. Climate change causes extremer weather, resulting in heavier rain ...
The issue of climate change has become highly important over the last decades. All sectors need to find solutions in order to reduce the carbon footprint and the built environment sector is definitely not an exception to this. One of the solutions is to use more biobased material ...

Improving circularity of inverted T-girders

Structural assessment of the prefabricated inverted T-girder system

Transitioning towards a more circular construction industry is crucial for achieving climate-neutral and fully circular operations by 2030. One significant contribution to this goal is fully utilising the reuse potential of prefabricated inverted T-girders. The primary challenge ...

Separating Construction Waste into High-Quality Materials

Recovery of EPS Foam Beads, PU Foam, and Cement

The construction industry is a major contributor to waste generation, with construction and demolition waste (CDW) constituting a significant portion of it. This research is centered on developing a technology to separate and recycle two types of plastics, EPS and PU, from cement ...
To limit the need for clinker in cement, CEM III/B is being used more and more in infrastructure. This cement mixture uses significantly less clinker, but instead uses blast furnace slag. Since this is a waste product of the steel industry, CEM III is supposedly much more sustain ...

Sustainable Design Development of a Concrete Lock Chamber

Reaching a Sustainable and Durable Design of a Ship Lock Concrete Hard Structure, Enabling Navigation Through the Haringvliet Storm Surge Barrier as Part of the Delta21 Project

Concrete is the second most used material in the world after water and recent trends show no slowing down of the concrete use around the world. Concrete is also a huge contributor to CO2 emissions as it makes up 8% of emissions. This study investigates the optimization of concret ...

The application of reusable hollow core slab connections in steel frames

Investigating the behaviour of a newly proposed reusable connection with increased tolerances

To align with the objective of the European Green Deal [46] policy of achieving net-zero greenhouse gas emissions by 2050, the construction sector must transition to a circular built environment. Most of the waste in the Netherlands is related to construction and demolition wast ...

The Development of a Parametric Framework for Embodied Carbon Design

A master thesis supporting the integration of sustainability into the design process

The building industry is the largest global contributor to carbon emissions. At the current rate of carbon emissions within this sector, the targets set by the Paris Agreement will not be achieved. Consequently, significant reductions in carbon emissions from the building industr ...
The pressing challenges of climate change and the increasing surplus of concrete waste is making it increasingly important to fully recycle concrete in a sustainable way. Since cement is by far the component that contributes most to the environmental footprint of concrete, it is ...

S. Alveolata is a tube-dwelling polychaete which can be found all the way from the coast of Norway all the way down to Dakhla in the Western Sahara. It is able to build large reefs structures from sand filtered from the water column. It is known to have impor ...

Vertical Extension of Council Estates

An effective method to optimize timber top-up designs, considering structural limits and environmental impact

The challenge of global warming is an increasing concern of the 21st century. The concept of sustainability is therefore considered of high importance. A major problem of the Dutch government is the growing housing demand. Also after the WWII, the Netherlands faced a housing cris ...
The urban heat island effect is a well-known and pressing problem in cities today related to urbanisation. It is the phenomenon of an increased ambient air temperature in cities compared to the surrounding rural areas. The use of nature-based solutions has been proposed as a way ...
Rijkswaterstaat aims to build circularly from 2030 onward, with the purpose of having a fully circular economy by 2050. Therefore, the aim of this study is to design a reusable modular superstructure, with a small span, which can replace an existing so-called volstortligger super ...
Equalized involvement of stakeholders in decision-making processes (DMP) allows them to achieve a balanced outcome, when aiming to create value for each participant. However, as the number of stakeholders increases, traditional methods of interactive engagement become more comple ...
This research addresses the environmental impact of foundations in lightweight housing units, focusing on BAM's timber house concept, FLOW. While the engineered timber superstructure is environmentally conscious, the foundation's contribution is often overlooked. The study aims t ...
In many places in Uganda, people do not have a connection to the drinking water supply system and there is a lack of treated water supply, meaning that people only have access to water a certain part of the day. As a result many people rely on springs, handpumps, rivers or lakes, ...
The aim of the current graduation project is the investigation of the potential of using hempcrete for the construction of residences in the Netherlands. The research focuses on the prefabricated block form of the material and investigates different aspects that can play a major ...

The jetty of the future

Reducing the environmental impact of a jetty platform structure by designing for reusability

The significant adverse contribution of the construction industry to greenhouse gas emissions and natural resource depletion has to be reduced. Regarding jetty platform structures, this challenge can be faced by designing for reusability, a promising concept for environmental imp ...

Reuse of concrete structural elements in practice

Design of a tool which stimulates structural engineers to reuse concrete structural elements by giving insight in structural safety, environmental impact, and economic impact

Due to global warming, in the construction sector there is aimed for a transition towards the circular economy. The past years, many utility buildings were demolished, consisting of a concrete structure. This results in concrete rubble which is often down- or recycled. For new co ...
