Donut Diet: Agricultural transition towards a circular, collective, and regenerative future

There is an imbalance in the nitrogen cycle, mainly caused by an increasingly intensive agricultural sector. This leads to the degradation of nature and the loss of biodiversity. Measures have been taken at European level to reduce the amount of nitrogen emitted by the agricultural sector, but this has caused a backlash as farmers in many...

Urban Livability Research and a Pollution Emission Case Study in Delft

At present, many studies have begun to focus on evaluating urban accessibility and livability, which can be a series of great guidance for future urban planning considering residents’ personal perceptions of various living aspects. It can be observed from the existing literature that urban accessibility has a mature evaluation system,...

Characterization of plastic transport in the Saigon River: An analysis of the river stretch that crosses Ho Chi Minh City conducted in the rainy season.

The Saigon River, coursing through Ho Chi Minh City, is a vital yet alarmingly polluted waterway. It ranks among the top 50 rivers globally contributing to plastic pollution. This study delves into the complex mechanisms governing the transport of floating plastic within a tidal system, such as the Saigon River.<br/>Our methodology adopts a...

The Fresh Rhine: A strategy for a clean and consistent water flow in a resilient Rhine River basin

The global water crisis could 'spiral out of control' due to overconsumption, pollution, and climate change. Building resilient freshwater systems is one of the most significant challenges in the face of climate change.<br/>The Rhine River basin is home to over 60 million people. It's a center for trade, industry, and food production. However,...

From algae to thread: A deep dive into a circular textile industry

Plastic is one of the most visibly polluting elements in our environment. From big plastic accumulation zones at sea to microplastic entering our everyday drinking water, plastic is becoming a more evident pollutant every day, which is damaging ecosystems, marine life and human health.<br/>This paper will envision a possible solution for plastic...

Nitrate Pollution in the Northern Cartago Region

Growing concerns about elevated nitrate levels in natural springs on the southern slope of the Irazu Volcano, Cartago province in Costa Rica, were the driving force for a multi-disciplinary study on the problem. The region is characterized by its high agricultural output and steep slopes. More than sixty springs located in the area are managed...

Towards OMPs Removal: Application of Visible Light Driven Heterojunction Based BiVO4/BiOI Photoanode for the Degradation of Paracetamol Demineralized Water

Currently, organic micropollutants (OMPs) are continuously and uncontrollably released into the water environment worldwide, as the reason for their special properties, OMPs removal has been a global challenge. This study focuses on acetaminophen degradation by photo-electrolysis (PEC) activities, which is one of the promising advanced oxidation...

Finding the plastic hotspots with (GIS) data: Synthesis Project 2021

The plastic pollution of aquatic environment is undoubtedly an emerging environmental risk, as it negatively affects ecosystems globally to a great extent. To prevent the plastic soup from growing even further, a Delft-based start-up Noria has developed plastic collectors, to remove plastic from rivers and canals before it reaches the ocean. In...

Pantai Project: The Trade-Offs Between Plastic Pollution and the Cost of the Waste Management System for a Household; a Case Study in the Watershed of the Petanu River, Bali

It has been determined that the plastic waste load in the Petanu river (Bali, Indonesia) can be as high as 2015.5 kg/day in the beginning of the rainy season. To restore the ecosystem and protect human livelihood this load should be reduced drastically. The enormous pollution rate is largely due to the massive amounts of mismanaged (plastic)...

Influence of 3D City Layout on Air Quality

In 2021, noise pollution monitoring will be mandatory in the Netherlands, which requires data on traffic that can be re-used for air quality estimation models. One of the important input parameters for the latter is the street type, which is required by the dilution parametrisation used within the air quality model.<br/>The goal of this project...

Plastic Discharge in Bali’s Rivers

Indonesia is one of the largest ocean pollutants in the world in terms of plastic emissions. The country has many tourist areas, including the island of Bali, which is the main tourist hub. The plastic problem is large around and on Bali, which has negative consequences for both the environment and the tourism sector. NGOs and the government are...

Pantai Project

For the past years large quantities of plastic waste have been accumulating on the beaches in Southwest Bali. This has economical, environmental and health implications in this area. This event mainly occurs between December to March. The objective of this report is to map the plastic waste problem in Southwest Bali and look for efficient...

DWIP - Durban Water Improvement Project

The water quality at the beachfront of Durban, KwaZulu-Natal, is currently insufficient to meet the Blue Flag standard, leading to health issues for the beach users. Since Durban can be recognised by its busy port and attractive beachfront, it is a major centre for tourism. This means that research on the source of this poor water quality and...

Project Hue: Report and field study on the water related problems and solutions in and around the Cau Hai lagoon and the Tu Hien inlet, Vietnam

The Tam Giang-Cau Hai lagoon system, lying in the Thua Thien-Hue province in central Vietnam, is affected by a tropical monsoon climate. This among others is the reason the Cau Hai Lagoon area has a long history of floods and other water related problems. Inhabitants are very dependent on the lagoon, as the main sources of income of people...

Improvement jetties near petroEcuador in La Liberdad, Ecuador

The first issue involves the accessibility of the pier of the refinery where coastal tankers moor to load or unload their cargo. The current depth at the pier is too small for large coastal tankers to fully load when mooring at the pier. In order to increase their cargo capacity, the depth in the mooring area should be increased. To expand the...
