Characterization of municipal solid waste in Kuwait: Sector-specific composition analysis and implications

ABSTRACT Municipal solid waste (MSW) characterization plays a pivotal role in devising effective waste management strategies conducive to fostering a circular economy. This study presents composition analysis across twenty-four subcategories sourced from residential, commercial, and industrial sectors in Kuwait. The study is conducted in accordance with the Standard Test Method for Determination of the Composition of Unprocessed Municipal Solid Waste (ASTM D5231). The results indicate that organic waste comprises 45.3%, followed by paper waste (19.9%) and plastics (19.8%). The remaining waste comprises glass waste (3.5%), diapers (2.7%), textiles (2.6%) and other waste. Paper waste (19.9%) consists mainly of mixed paper (12.1%), cardboard (3.7%), newspaper (3.3%), printer printouts (0.6%) and other office paper (0.2%). Plastic waste (19.8%) consists mainly of film (11.2%), PET (3.1%), HDPE (1.1%) and other mixed plastics (4.4%). Residential and mixed areas have the highest proportion of organic waste. Commercial areas produce the highest proportion of wastepaper (22.4%) and textiles (3.7%). Industrial areas produce the highest proportion of plastic waste (29.1%), most of which is film (17.3%). The study also provides an overview of the MSW management system in the country, an overview over the legislative framework, and forecasts of future waste generation rates with comparison to historical baselines. Implications: The precise and up-to-date characterization of municipal solid waste is imperative for scholarly journal submissions, as it establishes a foundational understanding of waste composition, aiding researchers and policymakers in the development of effective waste management strategies, resource recovery initiatives, and sustainable solutions to address the evolving challenges in waste management systems. This study provides detailed composition analysis for twenty-four municipal solid waste (MSW) subcategories collected across different sources: residential, commercial, industrial, and mixed areas. Time series forecasting is applied to predict MSW generation based on historical data obtained through the local municipality over the past decade. Factorial analysis is applied to investigate changes across source areas, and a hypothesis test is used to compare the current MSW composition against previous baselines. The results demonstrated significant variation across most waste categories. The plastic waste proportion has increased by 48.5% compared to 2013 data, despite awareness campaigns. Paper waste has also increased in proportion from 6.8% to 16.2%; this increase is associated with the mixed paper subcategory, which is mostly used for packaging. The composition data provided in this study are necessary for long-term monitoring, strategy assessment, and legislation associated with waste reduction and remediation.

Evaluation of Recycled Cardboard Paper as an Eco-Friendly Substrate for Rectenna and Ambient Radio Frequency Energy Harvesting Application

Developers of electronics for the Internet of Things are considering nonstandard substrate materials like recyclable, low-cost, and eco-friendly cardboard paper. From this perspective, this article reviews the design and experimental results of a 2D-rectenna for scavenging radio-frequency energy at 2.45 GHz on various cardboard paper substrates for both the antenna and rectifier. Four types of recycled cardboard material, each with different thicknesses, air gaps, and surface roughness, are selected for characterization. A linearly polarized rectangular microstrip patch antenna with microstrip transmission feeding is adopted for ease of fabrication. At 2.45 GHz, the antenna has a simulated and measured global gain of 2.98 dB and 2.53 dB, respectively, on a 2.2 mm thick cardboard material. The rectifying element consists of a voltage-doubler configuration connected through a T-matching network to the antenna. At low RF input power (−10 dBm), the maximum available DC output power is experimentally evaluated at 1.73 μW, 7.5 μW, and 8.5 μW for HSMS-2860, HSMS-2850, and SMS7306-079L diodes, respectively. The respective rectifiers with diodes SMS7306-079L, HSMS-2850, and HSMS-2860 exhibit optimal load values of 2 kΩ, 2.6 kΩ, and 8 kΩ. The rectifier designed using the SMS7306-079L diode experimentally reaches a maximum power conversion efficiency (PCE) of 14.2% at −5 dBm input power when the optimal load value is 1.5 kΩ.

Production of recycled paper using harmless municipal sludge as a new biomass filler

Abstract Due to a shortage of resources, exploring new biomass fillers has become critical for paper making. In this study, we reported an eco-friendly strategy for fabricating low-cost and efficient recycled paper with high mechanical properties using corrugated cardboard waste paper and harmless municipal sludge (HMS). First, the characteristics of HMS, including the particle size, pH, specific surface area, organic functional groups and organic component content, were analyzed. Then, the influence of the amount of HMS on the properties of the recycled paper was studied. Finally, the strengthening mechanism of biomass filling recycled paper was discussed. The results showed that HMS, a biomass filler for recycled paper preparation, exhibited excellent physical and chemical properties, with a median particle size of 6.395 μm, a surface area of 39.974 m2 g−1 and organic functional groups. The tensile index of the recycled paper with 30 % HMS was 13.10 Nm/g, which was 16.4 % greater than that of the unfilled paper and showed better thermal stability. This excellent performance could be attributed to the uniform distribution of HMS on the fiber surface, which improved the accessibility of hydrogen bond formation between fibers. Thus, this study proved that HMS was an excellent biomass filler for producing recycled paper.

Analysis of wetability properties for kraft paper and corrugated cardboard

Corrugated cardboard and kraft paper are widely used in the packaging industry, providing versatility of use and protection for products. The analysis of the wettability properties of these materials is extremely important, as it allows us to understand how they react to humidity. This research aimed to study the wettability properties of corrugated paper (PO) and kraft paper in order to expand knowledge about the quality of packaging produced with them. The study was conducted in the laboratory using corrugated cardboard (PO) with waves of type "A", "B", "C" "E" and kraft paper obtained from coils with and without coating. The wettability tests performed were total immersion, absorption time and drop penetration method. The collected data was interpreted using descriptive and graphical analysis generated by the R program. The research concluded that for the total immersion test, both materials absorbed more water in the vertical position. In the droplet absorption and penetration time tests, cardboards with type “E” waves showed the highest results when compared to other materials, providing a superior barrier for products that will be transported in boxes of this type. Furthermore, the coated Kraft paper also demonstrated good performance for drop penetration testing, confirming the coating's effectiveness as a moisture barrier.

Nanofibers isolated from unbleached date palm residues pulps and their use for paper coating

In the current work, cellulose nanofibers (CNF) were isolated from unbleached kraft pulps of date palm fruit stalks (DPFS) and date palm rachis (DPR) residues by ultrafine grinding. The isolated CNF were characterized by high-resolution transmission electron microscopy (HR-TEM), X-ray diffraction (XRD), zeta potential measurement, tensile strength properties, contact angle, as well as oil-proof testing. The CNF were applied as a coating material for cardboard paper sheets made from unbleached kraft DPFS and DPR pulps. The results showed that CNF from DPFS and DPR had close dimensions (4–14 nm in width and several microns in length) but their zeta potential was different (−44.65 eV and −51.46 eV for CNF from DPFS and DPR pulps, respectively), as well as their crystallinity (79.4% and 75.5% for CNF from DPFS and DPR pulps, respectively). CNF films from DPFS had tensile stress and Young's modulus of 113.3 MPa and 3.81 GPa, respectively, while those from DPR had tensile stress and Young's modulus of 71.0 MPa and 2.93 GPa, respectively. Films from DPFS CNF showed lower hydrophilicity than that from DPR, nevertheless excellent oil-proof property was obtained in both kinds of films. Coating of cardboard sheets prepared from unbleached kraft DPFS and DPR pulps with CNF layer of about 7-µm thickness resulted in significant changes in some physical properties of paper sheets, such as decreasing their air permeability, water vapor transmission rate, and water absorption; both kinds of CNF imparted paper sheets good oil-proof properties. CNF coating also imparted paper sheets remarkable wet tensile strength properties. The results showed the feasibility of utilizing date palm wastes in producing CNF films with distinct properties from low-cost unbleached kraft pulp, as well as using these CNF as a multi-functional coating material in papermaking industry.

Recycling Opportunities in a High Volume Academic Clinical Chemistry Laboratory

Abstract Many sectors of industry, including the biomedical sector, have quantified waste, and created sustainability strategies to mitigate its environmental impact. One of these strategies utilizes the waste hierarchy, a model which ranks the concepts reduce, re-use and recycle in order of the most to least sustainable practice. However, to date, the clinical laboratory has seldom been evaluated for total waste production and mitigation strategies and additional public reporting of the physical amount of waste produced in these areas are lacking in the literature. In this study, we aimed to identify specific wastes produced from performing the CMP over the course of a year in our automated clinical chemistry laboratory and what proportion would be recyclable. The total in- and outpatient testing volumes as well as volumes of quality control and calibrations needed to perform the CMP at our institution were collected retrospectively from 07/14/2021 - 07/14/2022. We further identified disposables waste items such as calibrator kits, quality control kits, patient blood specimen tubes, shipping packaging and reagent wedge kits that are necessary to perform the CMP. In addition, to obtain a conservative and consistent evaluation to the total amount of waste produced from the CMP, the average weights for components of the reagent test wedge kits which includes plastic wedges, cardboard shipping boxes, and paper package inserts were calculated. These weights in conjunction with total testing volumes was used to determine the total, recyclable, and non-recyclable waste produced from these disposable items. A total of 1089.2 kg of reagent kit wastes were estimated to be produced by performing the CMP over the course of a year. Of this waste, cardboard shipping boxes and paper package inserts were determined to be recyclable (233.6 kg) and the plastic reagent wedges were determined to be non-recyclable (855.5 kg) as they were not labelled with the universally recognized recycling code, were composed of proprietary plastic material, and contained biohazardous contaminants. Overall, 21.4 % of the total specific waste weight was found to be recyclable. The CMP is a small subset of the clinical chemistry test menu that produces a considerable amount of recyclable and non-recyclable waste.

Effect of fly ash-based calcium silicate on physical properties of cardboard paper

This work reported the possibility of using fly ash-based calcium silicate (FACS) as filler for papermaking and waste fiber to synthesize cardboard paper. The adverse effects of FACS filler on paper strength were improved by using cationic starch modification, surface size, and interlayer-filled technology. Physical property tests indicated that the increase of filler content leads to a decrease in paper strength and an increase in bulk, but at the same content, the strength properties of paper modified by cationic starch were significantly improved, and the absorption resistance was lower. The paper had better absorption resistance than the original FACS paper after surface size. In addition, the absorption resistance and strength of the interlayer filling paper were better than the original FACS-filled paper, and the absorption resistance was the best. The results support the potential use of FACS as a low-cost filler for cardboard paper production.

Evaluation of flue gas emission factor and toxicity of the PM-bounded PAH from lab-scale waste combustion

Atmospheric particulate matter (PM) has a significant threat not only to human health but also to our environment. In Hungary, 54% of PM10 comes from residential combustion, which also includes the practice of household waste burning. Therefore, this work aims to investigate the quality of combustion through the flue gas concentrations (CO, CO2, O2) and to identify and evaluate the negative impacts of PM and PAHs generated during controlled lab-scale combustion of different mixed wastes (cardboard and glossy paper, polypropylene and polyethylene terephthalate, polyester and cotton). Mixed wastes were burnt in a lab-scale tubular furnace at different temperatures with 180 dm3/h air flow rate. Chemical analyses were coupled with ecotoxicological tests using the bioluminescent bacterium Vibrio fischeri. Ecotoxicity was expressed as toxic unit (TU) values, toxic equivalent factors (TEF) were also presented. During the combustion same amount of O2 enters the reaction, but a different amount CO2 is generated due to the C content of the sample. The waste with highest C-content related to the highest CO2 emission. Increasing the combustion temperature produces more PM-bound PAHs, which remains the same composition in the case of plastic and textile groups. The TU of solid contaminants decreases with increasing combustion temperature and increases with the minerals which are left behind in the water from the solid contaminants.

The findings in this study imply that storytelling methods can improve children's vocabulary, if they focus on listening and listening to the content of the story.

The Hyperproduction of Polyhydroxybutyrate Using Bacillus mycoides ICRI89 through Enzymatic Hydrolysis of Affordable Cardboard.

Bioplastics are contemplated as remarkable substitutes for conventional plastics to accommodate green technological advancements. However, their industrial production has not been fully implemented owing to the cost of carbon resources. From another perspective, valorizing different paper mill wastes has become a prominent research topic. These materials may serve as an affording sustainable feedstock for bioplastic production. Adjustment of cardboard waste hydrolysate as suitable fermentation media for production of bacterial polyhydroxyalkanoates (PHAs) has been investigated. Cardboard samples were defibered and dried before enzymatic hydrolysis. The enzymatic degradation of commercial cellulase was monitored over 15 days. Interestingly, 18.2 ± 0.2 g/L glucose yield was obtained from 50 g cardboard samples using a 1.5% (v/v) enzyme concentration. The samples exhibited maximum weight loss values of 69–73%. Meanwhile, five soil samples were collected from local sites in Lodz, Poland. A total of 31 bacterial isolates were screened and cultured on Nile blue plates. Analysis of the 16S rRNA gene sequence of the most potent producer revealed 100% similarity to Bacillus mycoides. Cardboard hydrolysates whole medium, modified MSM with cardboard hydrolysate and nitrogen depleted MSM with cardboard hydrolysate were utilized for PHA production, followed by PHA productivity and cell dry weight (CDW) estimation compared to glucose as a standard carbon source. An impressive PHA accumulation of 56% CDW was attained when the waste hydrolysate was used as a carbon source. FTIR and NMR analysis of the isolated PHA indicated that functional groups of the polymer were related to PHB (polyhydroxybutyrate). Thermal analysis demonstrates that PHB and PHB-CB (PHB produced from cardboard hydrolysate) have degradation temperatures of 380 and 369 °C, respectively, which reflect the high thermal stability and heat resistance compared to the same properties for a standard polymer. This is the first demonstration of full saccharification of corrugated cardboard paper waste for high-level production of PHA. In addition, the attained PHB productivity is one of the highest levels achieved from a real lignocellulosic waste.

An Analysis of the World Paper Industry with a Focus on Europe and Trade Perspective

Abstract The pulp and paper manufacturing industry is currently facing sweeping changes due to the fact that supply and demand are dominated by different global players. These changes have significant effects not only on the paper and pulp production of countries but also on world economies thanks to the high level of trade between countries around the world. Based on the historical development of paper, our study examines today’s production around the world economies, shows the latest commercial trends in the paper and pulp trade, and makes a prediction on the effects of the data belonging to this sector on the trade of countries through using panel regression models. According to our results, we determined a significant relationship between the total world paper and cardboard production in Turkey and the European Union and the amount of pulp. On the other hand, a partial relationship was found between the European Union and Turkey’s paper production. In addition, we concluded that the amount of pulp used in paper and cardboard production was the factor causing the total paper production in the European Union and Turkey. In other words, we have established as a result of the analysis that as the amount of pulp used in paper and cardboard production increases, paper and cardboard production also increases at the same rate.

Design and manufacture of electromagnetic absorber composed of boricacid-incorporated wastepaper composites

With the effect of technological advances, the use of electrical and electronic devices has increased dramatically in recent years. Wireless technologies and related applications are mostly preferred for the communication of these devices with each other. Thus, people are easily exposed to electromagnetic waves in daily life. The extensive global use of these devices raises the question of their possible biological effects on human health. Also, electromagnetic waves influence the functioning of a nearby device. In this study, an electromagnetic absorber based on boric acid (5, 10, 20, and 30 wt%) added wastepaper was developed. Copper (Cu) and aluminum (Al) were also used as mineral additives for comparison. Three different kinds of wastepaper namely, office paper, newsprint, and cardboard paper were selected for the experimental study. The effect of varying boric acid contents on the electromagnetic absorption of the boards manufactured was evaluated and compared to Cu (30 wt%) and Al (30 wt%) added boards. The results show that newsprint has better absorption effectiveness than office and cardboard paper and absorption up to 40 dB was achieved. The absorption effectiveness of Al, Cu, and boric acid added boards was achieved at approximately 40, 30, and 20 dB, respectively. As a result, the electromagnetic absorption effectiveness of boric acid added the board is acceptable levels. Also, apart from the use of boric acid as a powder, it has been determined that the application of the surface as a layer is effective in absorption.
