“…Plastics have become a part of life in the modern civilization but have seemingly posed serious challenges (and in some cases tremendous threats) to the mankind. [1][2][3] In particular, nowadays, catastrophic deposition of fossil fuel-based commodity plastics (such as polyolefins, polyesters, polycarbonates, and foamed polystyrenes) on coastal areas find extensive discussion and these have even created unpleasant rumors. [4][5][6] The microplastics have created deeprooted concerns pertaining to possible environmental hazards and threats to human health and wellbeing of aquatic and soil organisms.…”

An agricultural waste, the wheat stalk, was used for the extraction of microcrystalline cellulose (MCC) and nanocrystalline cellulose (NCC) via a series of thermochemical and mechanical treatments. The MCC and NCC were then compounded with the biodegradable polymer, poly(butylene adipate-co-terephthalate), PBAT, by melt mixing. The properties of the composites were evaluated by soil composting, contact angle and water absorption measurements, scanning electron microscopy (SEM) and gel permeation chromatography (GPC). The cellulosic filler was found, as per SEM results, to uniformly disperse in the polymer matrix forming a quite homogeneous composite which visibly degraded completely within a few months under soil composting and showed high water absorption, these properties being enhanced with the filler content. Compared to the neat PBAT, the composites showed enhanced surface hydrophilicity thereby increasing the ability of degradation. In spite of seemingly remarkable change in mechanical stability of the polymers under soil burial for several months, relatively low lowering of the molecular weight was observed.

“…Actions like the aforementioned ones release carbon dioxide (CO 2 ) and black carbon (Wiedinmyer et al 2014); burning plastics that contain BFRs, as well as several additives (Hahladakis et al 2018b), is a significant source of air pollution, including the emission of unintended POPs, e.g. chlorinated and brominated dioxins, furans and polychlorinated biphenyls (PCBs) (Hahladakis et al 2018b;Verma et al 2016); it further poses several threats to all living organisms, since toxic particulate matter could potentially settle on crops or in waterways, degrading water quality and entering the food chain.…”

Plastics are nowadays considered to be the workhorse material of our modern society with an ubiquitous presence that has increased manifold over the past 60 years, providing several benefits to the global economy. However, inappropriate and/or uncontrolled disposal practices, poor waste management infrastructure and application of insufficient recycling technologies, coupled with a lack of public awareness and incentives, have rendered plastic waste omnipresent, littering both the marine and the terrestrial environment with multi-faceted impacts. This short communication/commentary aims at delineating the plastic litter global challenge providing, at the same time, scientific views and perspectives on properly dealing with this material type, both upstream and downstream.

“…This applies especially to those particles with a diameter below 2.5 µm, as their size allows them to enter the human blood directly. In the case of PM 10 particles (a diameter less than 10 µm) carcinogenic heavy metals, benzopyrenes furans, dioxins, etc., are the most harmful [2][3][4].…”

Hardware Efficient Solutions for Wireless Air Pollution Sensors Dedicated to Dense Urban Areas

This paper proposes novel solutions for the application of air pollution monitoring systems in so called 'smart cities'. A possibility of the implementation of a relatively dense network of wireless air pollution sensors that can collect and process data in real time was the motive behind our research and investigations. We discuss the concept of the wireless sensor network, taking into account the structure of the urban development in cities and we present a novel signal processing algorithm that may be used to control the communication scheme between particular sensors and an external network. We placed a special emphasis on the computational complexity to facilitate the implementation directly at the transistor level of particular sensors. The algorithm was verified using real data obtained from air pollution sensors installed in Krakow, Poland. To ensure sufficient robustness of the variability of input data, we artificially added high amplitude noise to the real data we obtained. This paper demonstrates the performance of the algorithm. This algorithm allows for the reduction of the noise amplitude by 23 dB and enables a reduction of the number of wireless communication sessions with a base station (BS) by 70%-80%. We also present selected measurement results of a prototype current-mode digital-to-analogue converter to be used in the sensors, for signal resolutions up to 7 bits.
