Summary: The steel industry, crucial to emerging economies, faces challenges due to its high energy consumption and greenhouse gas emissions. This study proposes two Carbon Capture and Utilization (CCU) processes for improving the industry's footprint without compromising its viability. The first process involves capturing CO2-SO2 and converting it into methane, with additional benefits demonstrated through enhanced adsorbent capacity and lifetime. These findings indicate that implementing the improved CCU system in stainless steel plants can reduce CO2 emissions without affecting profitability.

Summary: A life cycle-based environmental assessment was conducted to evaluate the mitigation of landfill gas emissions using biocover and gas collection with energy utilisation at aging landfills. The study found that biocover and gas collection systems with energy utilisation led to significant environmental improvements compared to the baseline scenario with no emission mitigation action. Scenarios representing biocovers with higher methane oxidation efficiencies were environmentally superior in terms of climate change impact compared to scenarios with longer gas collection and energy utilisation. Combining gas collection with energy utilisation and the subsequent installation of a biocover provided major improvements compared to scenarios with only gas collection and energy utilisation. It was concluded that a biocover, under the given assumptions, is more environmentally appropriate than gas collection and utilisation at aging landfills due to methane emissions escaping through the landfill cover.

Summary: This study investigated the direct activation of diluted CO2 in argon using a co-axial dielectric barrier discharge reactor powered by photovoltaic energy. The influence of initial CO2 and argon concentration on CO2 decomposition was examined, and it was found that lower CO2 concentrations resulted in higher conversion rates. The presence of the diluent gas (argon) also had a significant impact on CO2 decomposition, improving conversion rates at high argon concentrations. At the highest observed energy efficiency, a CO2 conversion rate of 40.2% was achieved. Furthermore, using photovoltaic energy was found to enhance the sustainability of the process, with a potential to offset 97% of the CO2 emissions associated with the process according to a life cycle assessment.

Summary: Biomass use and recycling can help reduce greenhouse gas emissions in the plastics industry. Polyethylene furanoate (PEF), a bio-based plastic, shows promise as an alternative to polyethylene terephthalate (PET) for small bottle applications. Life cycle assessments were conducted in the Netherlands, comparing the global warming potential (GWP) of PET and PEF bottles through multiple mechanical and chemical recycling trips. Results showed that after one recycling trip, bio-based PEF had 50-74% lower GWP compared to PET, depending on the waste management scenario. The study also highlighted the importance of deposit-based recycling systems in reducing overall GHG emissions for both bottle types.

Summary: Plastic entering the environment poses an increasing threat to ecosystems. This study estimates the annual mass of plastic waste generated and littered in the Netherlands, as well as its destinations. Two methods were used: a material flow analysis of separately collected plastic waste from various sectors and a mismanagement model based on litter observations and estimates of inadequately managed waste. The results show a significant amount of plastic waste being generated by households, clothing and textiles, and importation, and a large portion of it ends up in the environment abroad due to inadequate management. The study highlights the need for improved monitoring and reporting of plastic waste and its implications for achieving circular economy goals.

Summary: Electrochemical water splitting is crucial for hydrogen production, and improving the hydrogen separation rate from the electrode is essential for enhancing water electrolyzer performance. However, issues such as air bubble adhesion to the electrode plate hinder the process. Therefore, a methodology to investigate the two-phase flow within the electrolyzer is in high demand. This study proposes using a microfluidic system as a simulator for the electrolyzer and optimizing the two-phase flow by manipulating the micro-structure of the flow.
