    Opis:
    Bioremediation is the removal of heavy-metals such as nickel (Ni) using microorganisms and has been considered as an important field in the biotechnology. Isolation and characterization of microorganisms exhibiting bioremediation activities and their optimization to treat polluted wastewaters is a vital and difficult task in remediation technologies. In this study, investigation was carried out to isolate Ni (II) remediating microbial strains from soils contaminated with municipal solid waste leachate. Furthermore, Taguchi design of experiments were used to evaluate the influence of concentration, pH, temperature, and time on bioremediation of Ni (II) using isolated bacteria. This study concluded that Bacillus sp. KL1 is a Ni (II)-resistant strain and had Ni (II) bioremediation activity. The highest bioremediation of Ni (II) was observed as 55.06% after 24 h at 30ºC, pH 7, and 100 ppm concentration. Moreover, it was also observed that concentration is the most effective factor in the bioremediation process. In conclusion, we have demonstrated that bacteria isolated from soils contaminated with garbage leachate have the Bacillus sp. KL1 bacteria which can efficiently uptake and eliminate Ni (II) from contaminated sites and thus makes it possible to treat heavy-metal containing wastewaters in industry by using this microorganism at optimized conditions.

    Opis:
    In line with modern era, it is a high demand of renewable energies due to fossil fuels crisis. This study applies food garbage to produce biogas - an alternative renewable energy source – under lab-scale batch and semi-continuous reactors. Designing with four loading total solid (TS) rates of 1.0%, 1.5%, 2.0%, and 2.5%, the batch and the semi-continuous testing set up in 1.5 L and 21 L plastic reactors, respectively. Both testing was run in 60 days, produced biogas volume and compositions were recorded daily in semi-continuous reactors, and every ten days in the batch reactors. The results show that in batch testing, the biogas yields of treatments 1.0%TS, 1.5%TS, and 2.0%TS were better than those for treatment of 2.5%TS; however, %CH4 concentrations were better for treatments 2.0%TS and 2.5%TS. For the semi-continuous testing, the loading rate of 2.5% total solid food garbage produced the highest biogas yield which could meet the household demand of daily gas. Up to the day of 60, the %CH4 concentration was nearly 45% which proof the biogas can be used for cooking. H2S concentration in biogas was high which must be reduced to use produced biogas for cooking purpose. Further study needs to avoid accumulation of soluble organic acids, leading the low pH and inhibits methane-producing microorganisms in food garbage anaerobic reactor.

    Opis:
    Household waste is a global problem that many countries cannot cope with and deal with difficulty. In many regions of the world, a dynamic increase in the amount of waste generated is observed, which causes significant environmental pollution and excessive use of non-renewable resources. In the case of household waste, important indicators are not only its quantity per person but also its morphology. This study compares the amount of waste generated and its morphology by a household in Sri Lanka (Colombo) and Poland (Tarnów). The presented data comes from 2022, during a time of economic crisis caused initially by the COVID-19 pandemic and then due to the war between Russia and Ukraine. Currently, Sri Lanka is going through one of the greatest economic crises in its history. Poland is currently experiencing high inflation and reduced demand for many consumer goods due to continuous price increases. These events significantly affect the demand for various types of consumer goods and, paradoxically, this may reduce the amount of waste generated. It is important to identify and implement new strategies to recycle or optimize the usage of waste and develop value added products that would, in turn, have a positive impact on the domestic waste awareness. The results of the conducted research indicate a significant share of biodegradable waste in the stream of generated waste, especially in Sri Lanka. The vast majority of generated waste can be recycled, but sorting is required. Comparing the data obtained from this case study, 71% of food waste is generated in Sri Lanka, whereas 22.1% is generated in Poland. This indicates that Poland produces a significant amount of processed food. Moreover, the recorded plastic waste produced by Polish families is twice that of Sri Lanka. Furthermore, both countries indicate a positive trend to generate more waste in the future despite economic challenges faced locally as well as globally. Therefore, it is vital to understand the amount and morphology of waste as well as to implement more efficient and economical strategies to eliminate negative impacts.

    Opis:
    The study was conducted to determine the factors affecting the intention of people to segregate garbage in Vinh Chau town, Soc Trang province, Vietnam by surveying 198 households. Cronbach’s alpha analysis method, EFA analysis, and linear regression analysis were used in the study. The analysis results of Cronbach’s Alpha index, KMO and Bartlett's test showed that the questionnaire data used in the study was highly reliable and were suitable for EFA analysis. The results of linear regression analysis identified three factors including "subjective norm", "control of cognitive behavior" and "perceived level of garbage classification information" that had positive impact on intention of domestic solid waste classification of local people in Vinh Chau town, Soc Trang province, in which "subjective norm" was considered to be the most influential factor on the intention to classify domestic solid waste in the study area. Besides, the intention of the people to segregate the domestic solid waste was highly appreciated, but it has not been widely implemented in the locality. Therefore, the study proposed some governance implications based on the factors affecting the intention of people to classify household solid wastes. In particular, local authorities should pay special attention to propagating and disseminating policies and guidelines on the information of domestic solid waste and implementing a model of waste segregation at source.

    Opis:
    An algorithm for optimizing the routes of a set of vehicles used for the collection and removal of municipal solid waste in a metropolis is proposed. The algorithm eliminates the problem of applying heuristic methods for multi-agent optimization, which is NP non-deterministic polynomial-time-hard. The application of the algorithm leads to a guaranteed exact solution. Through the application of restrictions on the carrying capacity of vehicles, the size of the input matrix representing the transport network can be reduced to an adequate size. This process uses statistical information about the filling levels of container waste bins. The algorithm is applied to an example of two megacities. The shortest routes are built for different numbers of points (from 12 to 72) on the route. The dependence of the total mileage on the number of involved vehicles is studied.

    Opis:
    Decomposition of organic waste in dumping sites and landfills prompts the uncontrolled emission of greenhouse gases which enhances global warming and related issues. The present investigation estimated the total landfill gas, methane, carbon dioxide and non-methane organic compounds emissions from Mahmood Booti dumping site located at Lahore, Pakistan from 1996 to 2045. LandGEM 3.02 model was utilized to evaluate the gas emission with the volumetric methane 50%, production potential (170 m3/Mg), and methane generation rate (0.050/year). The findings demonstrated that organic and food wastes had the maximum quantity in the solid waste stream (63.46%). Methane measured from solid waste was 1.150E+03 (Mg/year) in 1997 in the first year after waste was accepted by landfill while the maximum methane generation rate happened from 2014 to 2018, i.e., from 4.049×104 to 4.654×104 Mg/year, respectively. The study finding highlighted that all gases emissions have an increasing/rising trend up to 2021 and then gradually their level will decrease because most of the organic fractions of solid waste would degrade with time. The findings of this study can be used to identify the impacts and contribution of MBODS in the global emission of greenhouse gases. The study concludes that proper management of landfill gas will not only decreases greenhouse gas emissions, diminishing adverse impacts on public health but can also be used as a sustainable energy source.
