Summary: Organic materials have potential for efficient sensor development in medicinal and material science applications. Single crystals of 4CFNCS exhibit plastic deformation when bent, twisted, or coiled, which is confirmed by synchrotron micro-focus X-ray diffraction mapping. These crystals are incorporated into a flexible piezoresistive sensor using a composite of PEDOT: PSS/4CFNCS, showing impressive performance at high-pressure ranges (sensitivity 0.08 kPa(-1) above 44 kPa).

Summary: Over 161 million tonnes of plastic packaging is produced annually, yet only a small fraction of plastic packaging is recycled. To help eliminate unnecessary plastic packaging and its associated pollution, interest is growing in re-usable packaging systems, such as returnable and refillable packaging. However, it cannot be assumed that reus-able packaging systems will be more sustainable than single-use alternatives.

Summary: Reusable packaging systems can tackle plastic waste and digital tracking technology can benefit the supply chain. However, there is limited research on consumers' engagement with digital reuse systems. This study investigates the barriers and enablers to consumer engagement and explores the impact of information about the systems on willingness to engage.

Summary: This study investigates the drift of MEMS accelerometers stored at room temperature for one year through finite-element analysis simulation and experiments. A comprehensive FEA model is established to simulate the deformation of the sensor package structure, and drift models for the scale factor and bias of the accelerometer are built. The simulation results are validated through testing and recording the outputs of packaged accelerometers. The findings provide meaningful guidance for the application of MEMS accelerometers.

Summary: One major application of plastic is packaging, which often involves printing ink for information and marketing purposes. However, the ink can contaminate the recycling process. To address this, de-inking with surfactants in an alkaline washing process has been used. This study evaluates the performance of different printing ink compositions and de-inking detergents under various washing scenarios for plastic recycling. The results show that pigments and binder systems can affect the de-inking process, and heating with NaOH is required for effective de-inking.

Summary: This paper summarizes the three latest studies on the flows of plastic packaging waste in Austria, Germany, and the Netherlands. Despite relatively comparable product markets, the three countries have different waste management systems, leading to variations in recycling rates.

Summary: In this study, films were produced using cassava starch modified by ozone technology and cellulose nanofibres. The addition of cellulose nanofibres improved certain properties of the films under certain conditions, although agglomeration was visible at higher concentrations. The inclusion of NCF in ozonated cassava films improved their properties for specific applications.

Summary: In this paper, a novel processing technology is developed to deal with hard-to-recycle plastic packaging waste contaminated with food residues. The technology effectively separates food residues from plastic waste materials, allowing for further re-use or recycling of the plastic packaging. Characterizations of the obtained fractions were conducted using spectroscopy, thermal analysis, and calorimetry, providing valuable insights for industrial players in plastic recycling.

Summary: Plastic pollution is a serious global environmental issue, particularly in Asia where a significant amount of plastic waste comes from food and drink packaging. However, the transition to sustainable packaging in the food and beverage sector is slow and inconsistent, with most corporate sustainability reports failing to address plastic pollution.

Summary: Packaging accounts for the largest demand in global plastic consumption, with around 60% used for food and beverage packaging. Our study quantified the food packaging generation from major supermarket and convenience store chains in Taipei, Taiwan, and found that 64.99% of the packaging was recycled. Identifying limitations in different stages and designing corresponding strategies is crucial to promote plastic food packaging recycling.

Summary: Polyethylene (PE) is widely used in plastic food packaging, and this study explores the migration of food contact chemicals (FCCs) across the lifecycle of PE packaging. Out of 377 FCCs detected, 211 were found to migrate from PE articles into food. Only 25% of the detected FCCs are authorized for food contact materials by EU regulation, and a significant number of both authorized and non-authorized FCCs exceeded the migration limits. The evidence on FCCs migration across the PE packaging lifecycle is incomplete, especially at the reprocessing stage.

Summary: An innovative approach combining large-sample questionnaires and experimental tests was used in this study to gather new data on plastic packaging waste in China. The study found that plastic packaging waste quantities varied across different regions and sectors, with the food takeaway sector generating the largest amount of waste. The study also proposed strategies to improve household plastic waste management.

Summary: According to the EU Circular Economy Package, recycling of plastic packaging waste (PPW) needs significant improvement by 2025 and 2030. Separate collection remains the crucial process, and the performance of current systems in Austria was analyzed. Results showed that rural areas had the highest collection rates of 74-77%, while urban areas had the lowest rate of 56%. A shift to target all plastic packaging instead of just plastic bottles is crucial to improve separate collection rates.
