Modeling of Information System for Air Waste Management

Analyzing of the Biodiesel Production From Cooking Oil

The large volume of industrial by-products and wastes from the construction, timber and paper industries has become a serious challenge worldwide. Recycling these industrial wastes as functional materials in the construction industry is an efficient approach for sustainable development. This study presents a pretreatment approach for recycling construction and demolition waste (CDW) and industrial side-streams (such as green liquor sludge, fiber waste, flotation sand and fly ash) in order to produce a geopolymer for the 3D printing of construction materials. A treatment approach was developed for screening the residues from CDW with a maximum size of 16 mm and for a combined line treatment for industrial side streams. The treatment processes utilized suitable and economical separation techniques for the recycling of waste materials. The crushing of the screened residues resulted in a homogeneous material size that facilitates the separation of mixed wastes and simplifies the classification of materials. The combined plant enabled the cost-effective treatment of various industrial wastes in a single process unit. The results show that the economic and environmental impact of the chosen techniques, in terms of their energy consumption, is highly dependent on the treatment line, separation technique and quantity of the individual waste that is processed. These recycled industrial wastes can be used as sustainable materials for the production of geopolymer concrete, contributing to the sustainability of the construction industry.

The impact of long-term crude oil pollution on soil microbial community structure in Bodo West Community, Ogoniland, Nigeria, was investigated to determine the amenability of the soil to microbial mediated remediation. Crude oil-polluted and pristine soil samples were collected approximately from 0 to 30 cm depth for both chemical and microbiological analyses. Total petroleum hydrocarbons (TPH) and polycyclic aromatic hydrocarbons (PAH) were determined using gas chromatograph–mass spectrophotometer (GC-MS). The soil microbiome was determined using the Illumina MiSeq platform. Results from this study were then compared with publicly available data from other oil-polluted sites. Taxonomic biomarkers and pathways associated with oil-polluted soils were detected using bioinformatics pipelines. TPH in the polluted and pristine soils were 7591 mg/kg and 199.70 mg/kg respectively, while the values of PAHs were significantly higher (p < 0.05) in the oil-polluted soil. Predictive functional and biomarker analysis demonstrated that microbes detected in the oil-polluted environment were involved in different metabolic pathways for degradation of a broad set of xenobiotic aromatic compounds. Established hydrocarbon degraders belonging to the families Alcanivoracaceae and Oceanospirillaceae were mostly detected in the oil-polluted soils. Sneathiella, Parvibaculum, Sphingobium, and Oceanicaulis were among biomarker taxa. The bacterial families Acidithiobacillaceae and Desulfobacteraceae were differentially more abundant in Bodo West spill site than any other site used for comparison. Furthermore, differentially represented species in our study site and other oil-polluted sites ranged from 21 to 42 bacterial families. The findings from this study revealed the bacterial community had a strong dependence on hydrocarbons and that acid-tolerant bacterial families can as well contribute significantly to biodegradation in the site and other polluted sites in Ogoniland usually known to have an acidic pH. Further research on Bodo West spill site will reveal the novel enzymes and pathways for enhanced microbial mediated eco-restoration.

Measuring industrial operational efficiency and factor analysis: A dynamic series-parallel recycling DEA model

The DOE Office of Industrial Programs, through the Idaho Operations Office, is sponsoring a program to develop and eventually demonstrate a wet oxidation system for energy production from water borne industrial waste materials and/or low-grade fuels for use in industrial processes. This program is considered a natural extension of previous DOE studies which have evaluated energy production through the wet oxidation of coal and peat. While the results of these studies were favorable for large-scale power generation, the Office of Industrial Programs believes that wet oxidation also has the potential to displace prime fuels on a smaller scale through the treatment of industrial wastes or other low-grade fuels. This report summarizes the feasibility of this program.

Environmental pollution by petroleum is an increasing global problem. In Russia this environmental problem is of such a large scale that it renders the excavation and off-site treatment of oil-contaminated soils and industrial wastes hardly possible. Therefore, in situ methods are attractive alternative. Bioremediation is a cost-effective and contaminant-specific approach. At the Institute of Biochemistry and Physiology of Microorganisms (Pushchino, Russia) there is a large collection of microorganisms degrading oil products. Their survival, stability, competitiveness, biodegradative activity, and efficiency under varying conditions have been investigated. Polycyclic aromatic hydrocarbons (PAH) belong to a recalcitrant group of environmental pollutants, They are components of oil and often occur in industrial wastes, The biochemical pathways of PAH catabolism and their genetic control in different strains were studied. It was shown that different combinations of host bacteria and plasmids changed growth characteristics and competitiveness of Pseudomonas strains. The transfer of degradative plasmids may enhance the biodegradative potential of indigenous microorganisms. Model systems were elaborated to determine the efficiency of PAH degradation [1], All these approaches can be used for the development of biotechnologies for cleanup of oil-contaminated soils.

Newer Aspects of Waste Treatment

Based on machine learning model for prediction of CO2 adsorption of synthetic zeolite in two-step solid waste treatment

At present, the world is committed to the development of environmentally friendly, sustainable and industrial safety. The effective treatment of industrial solid waste can be applied in the field of industrial safety. It is one of the ways to apply industrial solid waste to industrial safety to modify industrial solid waste and combine active powder to prepare industrial solid waste-based composite powder explosion inhibitors and apply it to underground coal dust explosion. This paper introduces the modification and preparation methods of industrial solid waste, and analyzes the good explosion suppression effect and good economic benefit of industrial solid waste-based composite powder explosion inhibitors on coal dust explosion. In this paper, four kinds of industrial solid wastes (red mud, slag, fly ash and sludge) were modified, and the modified solid waste materials with good carrier characteristics were obtained. Combined with a variety of active powders (NaHCO3, KH2PO4 and Al(OH)3), the industrial solid waste-based composite powder explosion inhibitors were obtained by solvent-crystallization (WCSC) and dry coating by ball milling (DCBM). Those kinds of explosion inhibitors can suppress the explosion of pulverized coal in 40–50% of cases. Compared with the powder explosion inhibitor commonly used in industry, it has a lower production cost and better explosion suppression effect. Those kinds of explosion inhibitors have a good industrial application prospect.

Pollutants are released into the atmosphere due to production and consumption energy especially from fossil. However, not only the environmental concerns but also the increase in energy demand promotes the researchers to develop new and current energy alternatives that cause zero- or low-negative environmental impact. Anaerobic fermentation can be used for the treatment of organic wastes (OW) such as kitchen waste, municipal solid waste, industrial organic waste, animal manure, and agricultural residues. The fuel produced from anaerobic digestion is environmental friendly. Kitchen wastes (KWs) are easily biodegradable organic material with high moisture, carbohydrate, lipid, and protein. The use of KW only in anaerobic digestion reduces the activity of methanogenic bacteria as a result of rapid accumulation of volatile fatty acids followed by a pH drop in the reactor, thus, adjusting C/N by some additives to accelerate the growth of methanogens and methane formation is necessary. The favorable pH for methanogens’ growth range of 6.5 to 7.2. Furthermore, the key factors controlling the production of volatile fatty acids during fermentation for methanogenesis represented in pH, temperature, C/N ratio, and hydraulic retention time.

Survey results from 72 mechanical manufacturers in Ho Chi Minh City (HCMC) in conjunction with related studies showed that industrial solid waste – hazardous waste (ISW-HW) treatment charges were operated in two forms: fixed and varied based on generated ISW-HW mass. Charges of collection – transport – storage – treatment – landfill for each waste composition varies widely (5 ÷ 20 fold), depending on the agreement between waste generators and solid waste services. Charges have not yet shown the relationship with treatment technologies, achieved treatment levels, as well as the correlation with transport distance and waste’s toxicity. Methodology for calculating ISW treatment costs by incineration was initially set. Treatment costs per ton of ISW from the mechanical industry were specifically established for each case of emission, corresponding to different payloads of transport means.

Industrial development is hand-to-hand with economic growth. It has a positive impact on many economic sectors and human living, but also produces hazardous waste which giving a negative impact on the environment and human health. Industrial wastes have a high contribution to climate changes, many human diseases, a mutation on animals and plants. Recently, there are many methods to overcome industrial waste include physical, chemical, and biological treatment. Moreover, waste management also is developed to optimize the treatment using 3R (Reduce, Reuse, and Recycle) and WTE (Waste to Energy). Therefore, this paper tried to discuss many technologies for industrial waste treatment and management includes recent research, benefit, and drawback.

Water is polluted when it constitutes a health hazard or when its usefulness is impaired. The major sources of water pollution are municipal, manufacturing, mining, steam, electric power, cooling and agricultural. Municipal or sewage pollution forms a greater part of the man's activity and it is the immediate need of even smaller communities of today to combat sewage pollution. It is needless to stress that if an economic balance of the many varied services which a stream or a body of water is called upon to render is balanced and taken into consideration one could think of ending up in a wise management programme. In order to eliminate the existing water pollutional levels of the natural water one has to think of preventive and treatment methods. Of the various conventional and non-conventional methods of sewage treatment known today, in India, where the economic problems are complex, the waste stabilization ponds have become popular over the last two decades to let Public Health Engineers use them with confidence as a simple and reliable means of treatment of sewage and certain industrial wastes, at a fraction of the cost of conventional waste treatment plants used hitherto. A waste stabilization pond makes use of natural purification processes involved in an ecosystem through the regulating of such processes. The term "waste stabilization pond" in its simplest form is applied to a body of water, artificial or natural, employed with the intention of retaining sewage or organic waste waters until the wastes are rendered stable and inoffensive for discharge into receiving waters or on land, through physical, chemical and biological processes commonly referred to as "self-purification" and involving the symbiotic action of algae and bacteria under the influence of sunlight and air. Organic matter contained in the waste is stabilized and converted in the pond into more stable matter in the form of algal cells which find their way into the effluent and hence the term "stabilization pond".
