Observing that the majority of SSTO programs failed due to the propulsion system being far ahead of its time. Furthermore, acknowledging the that the private launch markets is increasingly dominated by partly reusable TSTOs. This thesis aims to evaluate whether next generation rocket engines make an SSTO viable within a foreseeable economical...

The construction and waste industry would move towards applying Circular Economy (CE) strategies, to meet the circular ambition of the Dutch government before 2050. In order to accelerate this transition, it is necessary to explore and adopt more innovative and sustainable solutions within the construction and waste sector. A small amount of...

Bipolar electrosurgical vessel sealing is commonly used in human and veterinary medicine. This method of vessel sealing is often preferred over traditional suturing or clipping of blood vessels because it comes with the advantages of reducing intraoperative blood loss and operation time. Most bipolar vessel sealers are disposable. The high costs...

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 impact reduction. However, this principle is not yet being widely...

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 construction projects, new concrete elements will be produced....

We are currently facing a transition of economy. Previous years were focused on a linear economy, consisting of the make-waste concept. The products that are made with raw materials are thrown away after its use. Unfortunately the Earth does not contain an unlimited source of materials and we need to focus on reusing materials. Concluding to...

In current LCA studies, the environmental footprint of transport processes is calculated using the weight of the product and the distance travelled. This cannot be considered accurate for returnable packagings that reduce in volume when empty. The weight of the freight as well as the number of trips needed varies and is not taken into account in...

The renaissance of reusable space launch vehicles that is being witnessed in the current space industry demands a new cost estimating approach, which takes into account not only the time dependency in the lifecycle brought upon by reusability, but also the complementary considerations of minimizing cost and reliability. To achieve this end, a...

In a constantly evolving urban environment, it is important that we design structures with future adaptability in mind. Bridges for example can have very long life spans, but within their life span their use might change or even become obsolete. Disposing of the bridge, which can still be in perfectly good shape, would be a terrible waste of...

Smoking tobacco and physical inactivity are key preventable behavioural risk factors of cardiovascular disease (CVD). Computerised coaching systems can help individuals to modify risky behaviours, thereby preventing CVD. However, most reported eHealth or computerized coaching systems are hard to reuse in slightly different settings. To provide...

The demountable and reusable steel-concrete composite structures contribute immensely at the sustainable development in construction. The main technical practice which allows for demountability and reusability is the use of demountable shear connectors in their floor systems. These demountable shear connectors can satisfy the need for composite...

The commercialization of the space industry has led to a reduction in size and weight of satellites and launching vehicles, which have effectively reduced the cost of space services. The costs of launching payloads to space can be significantly reduced when the launching vehicles are reusable. The two-stage-to-orbit system with a winged,...

The last 20 years has brought with it a surge in efforts toward the Red Planet as the next frontier is human space exploration draws closer. Many concepts have been proposed for a sustained human settlement on Mars, with NASA’s ISRU-to-the-wall campaign identifying the need for a shuttle vehicle between theMartian surface and a station in an...

Online meal delivery platforms are growing worldwide. Nevertheless, the takeaway business model is currently the major source of plastic packaging waste generation. The alarming growth of plastic pollution leads to action among governments worldwide resulting in single-use plastic bans. A handful of start-ups offer reusable food container...

Cleaning is an important factor in the reprocessing of hollow medical instruments. Inadequate cleaning disturbs the disinfection and sterilization process and increases the risk of cross-contamination. An automated washer-disinfector is often used for cleaning medical instruments, by using fluid flow. fluid flow induces shear stress at the wall...

Vacuum extraction is a form of assisted vaginal birth where a vacuum cup is attached onto the fetal head by means of suction on which traction force is then exerted to facilitate birth. Vacuum extraction is often regarded as a safer option than the cesarean section and forceps delivery, due to decreased risk of maternal en fetal complications....

This project has been about taking a first step towards developing a radically innovative circular building system, with the double goal of vastly reducing climatic impact of building construction, as well as strongly reducing costs to aid the current housing crisis. The first step in this project has been research into the reusability of...

Minimally Invasive Surgery (MIS) has made tremendous impact on hospitals worldwide. Introduced as a patient friendly alternative to open surgery by significantly reducing incisions size, benefits such as faster patient recovery time, and less pain for patients, are achieved. However, in MIS, rigid instrument shafts can impair surgeons’ dexterity...

With Mars colonisation becoming a reality for the near future, it is of importance to analyse how crew and cargo can be transported between Earth and a colony on Mars. This article is a feasibility and design study of a launch vehicle whose mission is to shuttle crew and cargo from Low Mars Orbit to a colony on the Martian surface. A single...
