Accumulation of non-degradable plastic waste in the environment might be prevented by the use of biodegradable polyhydroxyalkanoate (PHA). In this study, the thermophile Schlegelella thermodepolymerans produced up to 80 wt% PHA based on dry cell mass. The largest PHA granules were found in the cells …

This paper presents challenges in city logistics for circular supply chains of e-e-waste. Efficient e-waste management is one of the strategies to save materials, critical minerals, and precious metals. E-waste collection and recycling have gained attention recently due to lower collection and recycling …

Most world governments are concerned with waste disposal. The large accumulation of these waste items is causing environmental and monetary issues. According to (Awuchi, 2019), the predicted average daily production of plastic waste is 15.4 billion pieces. Plastic waste is the most prevalent form of …

This thesis is written for Modint, the trade association that consults companies for the fashion- and textile industry in the Netherlands. Pursuing a circular economy is a worldwide priority and the EPR legislation also known as Extended Producer Responsibility, requires the fashion- and textile industry …

Circularity and recycling are gaining increased attention, yet the amount of recycled plastic applied in new products remains low. To accelerate its uptake by businesses, it will be useful to empirically investigate the barriers, enablers, needs and, ultimately, requirements to increase uptake of recycled …

Plastic is one of the biggest contributors to pollution of the planet. Due to the low recyclability of oil-based plastics, most plastic is being disposed into the environment. According to plastic oceans, 10 million tons of plastic are dumped into oceans annually. Currently, researchers are developing …

Bulk molding compound (BMC) thermoset (bio) composites are difficult to recycle because they cannot be melted for reprocessing. However, this group of materials is often used in high-end applications where strength and lightweight materials are required, such as boat hulls, aircraft parts, car parts, …

As an essential nutrient for food production, phosphate is largely used in fertilizers to enhance crop growth (Baishya et al., 2016; Hasanuzzaman et al., 2018). Regardless of its enormous demand, the only concentrated P source is phosphate rock and the resource is finite (Cordell & White, 2011; Smit …

The following research justification report shows to which extent adding HemCell prebiotics to the current product line is financially feasible. Before coming up with a calculation model, some more background research needed to be done. Four information gaps were identified on which this research is …

The Dutch government and leading academics in the field of circular economy propose that “repurposing”, i.e., finding new usages for discarded material, is important to reduce resource usage. Waste collectors, municipalities and start-ups increasingly find ways to develop circular business models, aiming …
