Enhancing the Biodegradability of LDPE Plastic Waste through Sustainable Bacterial Isolates from Saudi Arabian Soils

ABSTRACT: The unregulated utilization and extensive disposal of synthetic polymers, resulting in excessive buildup in natural ecosystems, has become a significant cause for alarm. Consequently, there is a pressing need for the development of sustainable plastic degradation methodologies. In the present study, the potential of new Bacillus strains isolated from five petroleum stations to degrade plastics LDPE (Low-density polyethylene) and polyester: plastic bags, bottles and cups was investigated. Following bacterial screening and molecular identification, two strains with no previously known plastic removal ability, Bacillus cytotoxicus SB 9 and Bacillus sp. revealed good plastic biodegradation ability at 37 ºC surfaces with Scanning Electron Microscopy (SEM) and pronounced weight loss were observed with the mixture of bacterial isolates mainly on the plastic cup, bottle and then the bag. These results indicate the ability of these novel Bacillus sp. to develop a synthetic polymer degrading mechanism as a promising, smart eco-friendly plastic waste management for the soil environment.

Pengaruh Penggunaan Limbah Plastik LDPE sebagai Modifikator Campuran AC-WC

In recent years, the increasing amount of plastic waste in many cities in developing countries, including Kupang City, has become a serious environmental problem. The use of plastic waste as a pavement material is one solution to deal with the problem of plastic waste. One type of plastic that can be used as an asphalt mixture modification material is Low Density Polyethylene (LDPE). This research aims to determine the use of LDPE plastic waste modified with AC-WC (Asphalt Concrete-Wearing Course). Five variations of AC-WC mixture were made based on LDPE plastic waste content of 6, 7, 8, 9, 10% based on optimum bitumen content (OBC). Marshall test method was used to determine the OBC and to evaluate the marshall characteristics of LDPE modified AC-WC. The OBC of conventional AC-WC was found to be 5.23% by weight of total aggregate while the ptimum plastic modified bitumen content (OPMBC) of LDPE modified AC-WC was 7.45% by weight of OBC. AC-WC modified with 7.45% LDPE waste had 47.98% higher OPMBC compared to conventional AC-WC

Utilization of fuel energy from single-use Low-density polyethylene plastic waste on CI engine with hydrogen enrichment – An experimental study

An effective strategy to reduce global waste is to convert the waste into Energy effectively. Single-use Low-density polyethylene (LDPE) plastic waste poses an environmental challenge by slower decomposition. Pyrolysis is one of the best techniques for converting waste plastics into Waste Low-density polyethylene pyrolysis oil (WLPO), a useful energy source similar to diesel. Operating an engine directly with neat WLPO lowers the performance and increases carbon monoxide, unburnt hydrocarbons, and smoke emissions than diesel. Hence, to enhance the performance and emission characteristics of the engine operating with WLPO dual fuel mode, different flow rates of hydrogen induction from 3 to 12 lpm were studied. The results were compared with diesel and neat WLPO. 12 lpm of hydrogen induction shares 15.19 % of hydrogen energy in combustion for WLPO. Compared to neat WLPO, 12 lpm hydrogen induction has a percentage increase of 22.89 in brake thermal efficiency, 15.88 in peak pressure, 60.85 in heat release rate, and 61.46 in Nitrogen oxides, as well as a percentage decrease of 53.42 in smoke, 48.94 in carbon dioxide, 53.99 in unburnt hydrocarbons, and 86.86 in carbon monoxide. Also, these are all similar to and better than the neat diesel operation except for the NOx emission. The hydrogen induction with WLPO increases the engine performance and reduces the smoke and carbon emissions. This fuel usage with hydrogen in IC engines indirectly supports LDPE plastic waste reduction by utilization and reduces objectionable emissions.

<p class="abstrak"><em>The demand for fuel oil is increasing day by day, resulting in the depletion of oil and gas reserves in Indonesia. Rice husk waste biomass and low-density polyethylene plastic are wastes that can be utilized as alternative fuel sources by pyrolysis method. Pyrolysis is the process of burning organic and synthetic materials in conditions of little or no oxygen by utilizing heat from high temperature combustion. Pyrolysis method processing requires a heater to burn the material during the process. Efforts that can be made are the use of biomass stoves as the right solution because of the availability of abundant and cheap raw materials, biomass stoves can also provide solutions to reduce the impact of environmental pollution smoke. The purpose of this study was to determine the temperature produced by the biomass stove and the effect of the comparison of the composition of the biomass mixture of rice husk waste and low density polyethylene plastic waste on the quantity of pyrolysis oil. This research uses experimental method with quantitative descriptive analysis technique. This research was conducted by pyrolyzing a mixture of rice husk biomass waste and low density polyethylene plastic waste with variations in composition ratio of 0%:100%, 25%:75%, 50%:50%, 75%:25%, and 100%:0%. The pyrolyzed oil was then filtered and tested for quantity. The test results show that the biomass stove can be used as a heater in a pyrolysis device with a capacity of 4 kg of coconut shell briquettes. The use of coconut shell briquettes as fuel has the advantage of being able to produce higher heat and last longer than charcoal. The biomass stove can produce the highest pyrolysis temperature reaching 665.5°C at the bottom, 541°C in the middle, and 430.3°C at the top. There is an effect of variation in the composition of the mixture of rice husk waste and low-density polyethylene plastic waste on the quantity of pyrolysis oil. The composition of more rice husk waste compared to low density polyethylene plastic waste produces less quantity of pyrolysis oil, while the comparison of the composition of more low density polyethylene plastic waste compared to rice husk waste produces pyrolysis oil with more quantity. This can be seen from the quantity of pyrolysis oil produced ranging from 265 ml to 853.3 ml. </em></p>

Nickel promoted Si-rich ZSM-5 nanocatalyst remarkably converts LDPE plastic waste to gasoline range hydrocarbons in a dual-bed semi-batch reactor at atmospheric pressure

Catalytic pyrolysis is an environmentally friendly recycling method, which has attracted remarkable attention due to worldwide issues of the production and accumulation of plastic wastes. In this work, the catalytic pyrolysis of Low-density polyethylene (LDPE) was carried out in a dual-bed semi-batch reactor over the Si-rich Ni/ZSM-5 nanocatalyst at atmospheric pressure. The parent nanocatalyst was prepared by hydrothermal technique and modified with nickel promoter (0–25 wt%). The properties of the nanocatalysts were characterized by XRD, FTIR, FE-SEM, EDX, TEM, BET, NH3-TPD, and TG-DTA techniques. The results showed the high crystallinity, spherical particles, and high specific surface area (376 m2g−1). The impact of operational conditions was evaluated to maximize the production of the high value-added compounds. The high percentage of the Ni promoter (25 wt%) led to the highest amount of gasoline range hydrocarbons (61%). The appropriate operational conditions were temperature of 525 °C, catalyst to plastic ratio of 1:20, and 2.5 ml min−1 nitrogen flow rate, resulting in the best product distribution: aromatics (39.4%), olefins (28.3%), and paraffins (15%). The reusability of the nanocatalyst showed high performance and more aromatic production. The characterization results of the used nanocatalyst confirmed the high stability through the pyrolysis reaction and lack of significant structural defect. The developed nanocatalyst represented the high activity through the pyrolysis of the real LDPE plastic waste, including the major product distribution in the gasoline range hydrocarbons.

Downcycling of one-time used plastic waste to DICI engine combustion energy through pyrolysis with less NOx emission

Plastic waste elimination is more important for environmental pollution. Alternate fuel is essential for future IC engine applications because of fossil fuel availability. This study focuses on both challenges by creating combustion energy for direct injection CI engines from the wastes with lesser NOx emissions. Plastic wastes of low-density polyethylene (LDPE) have the most negligible recycling value based on their collection point of view from municipal wastes. Conversion of this LDPE plastic waste into alternate fuel for CI engines by pyrolysis will provide value for that waste. The combustion, emission, and performance of neat pyrolyzed oil of LDPE plastic wastes (POLPW) were studied with exhaust gas recirculation (EGR; 0%, 10%, and 20%) in a 1500 rpm 5.2 kW engine on different loads. 20% of EGR used POLPW fuel produced 31.63% of brake thermal efficiency and 62.28% reduction in NOx (596 ppm) than diesel at maximum load. Pyrolyzed oil of low-density polyethylene plastic wastes can be utilized as a 100% substitute fuel in CI engines with an EGR of 20%. This will provide alternate fuel and low-value plastic waste downcycling, initiating environmental pollution reduction.

Hydrocracking of LDPE Plastic Wastes into Liquid Fuel by Natural Zeolite Supported Nickel Metal

Hydrocracking of low-density polyethylene (LDPE) plastic over an impregnated Ni catalyst on activated natural zeolite (Ni/ANZ) has been carefully investigated. Natural zeolite was firstly activated with HCl 6 M under reflux conditions followed by wet-impregnation with Ni salts. The obtained powder was calcined at 500 °C followed by a reduction with H2 at 500 °C. The resulting Ni/ANZ catalyst was characterized by using FTIR, SAA, and XRD. The hydrocracking of LDPE plastic was carried out in a semi-bath stainless steel reactor. The resulting liquid product was analyzed by GC-MS. This study found that the hydrocracking process was carried out effectively at 200 °C. The selectivity towards gasoline (C5-C12) at 200 °C could be boosted by employing the Ni/ANZ catalyst (68.23% yield) which is much higher than the uncatalyzed pyrolysis (37.87% ).

Laboratory investigation on the moisture susceptibility and fatigue resistance of hot mix asphalt modified with high- and low-density polyethylene plastic wastes

The demand for better management of plastic wastes all over the world is increasing. Polymers such as high-density polyethylene (HDPE) and low-density polyethylene (LDPE) are examples of these wastes. Studies showed that these could be used as polymer modifiers that could improve asphalt pavement performance. Although several studies had been conducted to evaluate the performance of asphalt mixtures with HDPE and LDPE, conflicting results had been seen. Additional research is still needed to find out the true effect of plastic on the performance of asphalt mixtures. Hence, this study assessed the performance of hot mix asphalt (HMA) modified with HDPE and LDPE pellets. The Marshall mix design was used to prepare, evaluate HMA mixtures and determine the optimum percentage of HDPE and LDPE that can be added to HMA. Moreover, wheel-tracking, and immersion-compression tests were used to evaluate rutting resistance and compressive strength of HMA mixtures, respectively. Results showed that the addition of 8% HDPE and 8% LDPE by weight of bitumen are the optimum contents. The performance of the HMA mixtures with HDPE and LDPE in terms of fatigue resistance and moisture susceptibility shows improved results. This proves the potential use of the materials as polymer modifiers in HMA. Moreover, HMA with HDPE when compared to the HMA with LDPE shows better results in reducing the moisture susceptibility and improving the fatigue resistance of HMA.

Non-catalytic and Catalytic Pyrolysis of Low Density Polyethylene LDPE Plastic Waste Into Fuel Ranged Hydrocarbons Using Nigerian Local Clay Composites

Plastic utilisation and plastic waste accumulation is rising in recent times mostly in developing countries. The utilization of modified and unmodified Nigerian bentonite clay as catalyst for preparation of fuel-ranged hydrocarbons from low-density polyethylene (LDPE) sachet wastes by pyrolysis was investigated. Pyrolysis of LDPE was done using locally fabricated semi-batch reactor condenser column. The products were characterized using Fourier transform infra-red spectroscopy (FTIR) and gas chromatograph with a flame ionisation detector (GC-FID). Physicochemical properties of the products were determined using standard analytical methods. The products from non-catalysed contained mostly saturated hydrocarbons compared to that of the catalytic process which contained more branched-chain hydrocarbons and mono-substituted aromatics. Physicochemical properties of the product from non-catalytic process showed resemblance to those of kerosene and diesel fuel while the properties of products from catalytic pyrolysis closely approximates those of commercial gasoline. This implies that the catalytic process gave products that were more suitable as fuels for auto engine which require higher octane number based on their naphthenic and aromatic content.

Utilization of LDPE Plastic Waste for Mixed AC-WC Asphalt

Road infrastructure development in Kabupaten Ketapang necessitates asphalt as a building material to support the acceleration of growth. Innovations are required to reduce the consumption of materials derived from nature to conserve diminishing natural resources. Plastic is an element that requires between 500 billion and one trillion years to decompose. With the addition of plastic to asphalt, the permanent deformation value of the mixture decreased and its dynamic stability increased, as determined by the wheel track test. Marshall tests on asphalt mixtures containing plastic revealed that the addition of up to 3% plastic increased the HRA mixture’s stability, bulk density, compacted aggregate density (CAD), and Marshall Quotient. This study evaluated the Marshall value of the modified AC-WC asphalt layer by adding a mixture of Low-Density Polyethylene (LDPE) plastic waste with a variety of mixed properties. Each of the four variations of the AC- WC mixture (0%, 2%, 4%, and 6% LDPE) that met the specifications yielded stability values. LDPE at 6% has the highest stability value, while LDPE at 0% has the lowest stability value.

Marshall and Cantabro characteristics tests were conducted to evaluate the resulting mixture. The results of this study indicate that the stability value meets the REAM specifications, namely 350 - 800 kg. Marshall test results with the use of LDPE plastic waste as an additive to the test object meet the characteristics of Marshall except for Marshall Quotient (MQ) and voids filled with bitumen (VFB).

Investigating the effect of pyro-catalytic temperature on gasoline production from low density polyethylene (LDPE) plastics waste

This research aims to produce hydrocarbon fuels from LDPE plastic waste by the pyro-catalytic method. Pyro-catalytic of LDPE samples was carried out at 400, 425, 450, 475, 500, 525 and 550 °C, heating flow rate of 15 °C/min with zeolite catalyst.
