Waste disposal in marine waters is of importance to coastal engineers because of the ever-increasing requirements for an effective means of dilution of both municipal and industrial wastes. There are many considerations that enter into a satisfactory waste disposal method by dilution, but to the engineer two major considerations must be made. These are, first, the rate of diffusion and, second, the level of dilution necessary to effect disposal. These considerations become quite involved because of the varying conditions which influence dilution or diffusion processes and the uses of the water, which determines the criteria for a satisfactory dilution level. Thus, the dilution levels necessary will be dependent on the nature of the material and the area of dispersal.

Sustainable waste management, particularly in industrial areas, is one of the major challenges of developing countries. Among the important issues in the overall process of industrial wastes management is the necessity of suitable site selection for waste disposal. Considering the effects that the disposal sites exert on their surrounding ecosystem and environment, these sites should be located in places with the minimum destructive effects and the lowest environmental impacts. The aim of this research is to outline important criteria for industrial zone waste disposal site selection and to select optimal and proper disposal sites in the Salafchegan special economic zone. This region, as one of the most important industrial areas and closest to the country’s political–economic center, enjoys a privileged and unique position for producing, exporting, and transiting goods and products. There are various parameters involved in the optimal selection of suitable industrial waste disposal sites. In this case study, issues such as the depth of groundwater, distance from surface- and groundwater, access routes, residential areas, industries, power transmission lines, flood-proneness, faults, slope, and distance from gardens and agricultural lands were taken into account. Following selection and preparation of the maps related to the influential parameters, assigning weights was done through the Analytical Hierarchy Process (AHP) and using expert comments. At this stage, the maps and weights related to them were introduced into an index overlay model to obtain new maps from combining the influential parameters. Thereafter, the areas with the first and second priorities were selected and out of each one, four sites were suggested for disposing of industrial wastes. The sites with the first and second priorities were specified as A1, A2, A3, and A4 and B1, B2, B3, and B4, respectively. The area, groundwater depth, distance from residential areas, distance from the Salafchegan special economic zone, the direction of the predominant wind, and the land use of the selected sites were also investigated.

Abstract Bacteria belonging to Rhodococcus genus represent ideal candidates for microbial biotechnology applications because of their metabolic versatility, ability to degrade a wide range of organic compounds, and resistance to various stress conditions, such as metal toxicity, desiccation, and high concentration of organic solvents. Rhodococcus spp. strains have also peculiar biosynthetic activities that contribute to their strong persistence in harsh and contaminated environments and provide them a competitive advantage over other microorganisms. This review is focused on the metabolic features of Rhodococcus genus and their potential use in biotechnology strategies for the production of compounds with environmental, industrial, and medical relevance such as biosurfactants, bioflocculants, carotenoids, triacylglycerols, polyhydroxyalkanoate, siderophores, antimicrobials, and metal-based nanostructures. These biosynthetic capacities can also be exploited to obtain high value-added products from low-cost substrates (industrial wastes and contaminants), offering the possibility to efficiently recover valuable resources and providing possible waste disposal solutions. Rhodococcus spp. strains have also recently been pointed out as a source of novel bioactive molecules highlighting the need to extend the knowledge on biosynthetic capacities of members of this genus and their potential utilization in the framework of bioeconomy. Key points • Rhodococcus possesses promising biosynthetic and bioconversion capacities. • Rhodococcus bioconversion capacities can provide waste disposal solutions. • Rhodococcus bioproducts have environmental, industrial, and medical relevance.

To reduce waste volumes and recover valuable products, char was synthesized via co-pyrolysis of rice straw (RS) with spent tires, sulfur wastes, and CO2. The inclusion of wastes and CO2 in pyrolysis of RS was hypothesized to enhance the sorption ability of char for various contaminants, including 2,4-dinitrotoluene (DNT), 2,4-dichlorophenol (DCP), lead, barium, chromate (CrO42−), and selenate (SeO42−). Using a lab-scale electrical furnace, the co-pyrolysis was conducted, and the soprtion capacity of char was evaluated via a series of batch sorption experiments. The maximum sorption capacity of spent tire–RS char for DNT was 16.8 ± 0.2 mg g−1, much higher than that of RS biochar (10.1 ± 0.3 mg g−1) due to increasing carbon content from the spent tires. The sorption of DCP to the spent tire–RS char was also enhanced via hydrophobic sorption to carbon residues, although not to the same degree of DNT due to deprotonation of the DCP. Compared with RS biochar, co-pyrolysis with raw sulfur wastes and CO2 enhanced sorption of lead, barium, and chromate, which can be attributed to increased cation and anion exchange capacities resulting from developments of oxygen or sulfur-containing functional groups. Sorption of selenate was strongly affected by pH. The results suggest that co-pyrolysis of agricultural and industrial wastes and CO2 is a promising option for the final waste disposal and the production of valuable char, which can be selectively customized for various types of contaminants as sorbents.

Environmental issues around the world have become more acute in recent years. This is due to a significant in-crease in industrial wastes from various industries and waste of the population called municipal solid wastes. Re-cently, more attention has been paid to waste disposal issues, but still not enough. The main waste in animal hus-bandry is manure, and in population centers –municipal solid waste. The separation of manure and solid wastes into fractions not only increases the efficiency of using the area, but also leads to decreased transportation costs. The study of the wastes issue in the Altai Region has shown that there is a significant amount of unused manure as organic fertilizers and significant volumes of municipal solid wastes. The existing manure disposal technology provides for the removal of manure to the field or temporary storage on the farm that causes area contamination. There are various ways of organic waste disposal: thermal, biological, chemical, electrophysical, and mechanical ones, as well as their combinations. To solve this problem, an integrated approach is advisable -the use of the adhesive properties of cattle manure to bind municipal solid wastes and making briquettes from the resulting mixture. This method allows solving the ecologic problem both on the farm and near population centers. The results of the conducted experi-ments allow making conclusion that the fuel briquettes ob-tained in this way retain their shape and, in a dried state, support combustion. The technology of separating manure into fractions will significantly simplify the disposal of solid and liquid fractions.

Abstract Industries have played vital roles for economic development that enable people to create new and better livelihoods, more income, and modern life systems. However, Ethiopia has little benefited from industry sector due to limited number of industries with less advanced technologies. This study was conducted in Addis Ababa, the Capital City of Africa. Datasets were collected from 2,204 institutions through structured interview, field observation and GPS points. Datasets were entered, cleaned and analyzed using a relational database system in Visual Basic and MS-access database environment. Spatial distribution of industries indicates that only 18% of industries were found in industry zones, while 82% are outside industry zones and of which 78% of them are found in residential areas. Industrial wastes are disposed either to nearest river or open field. The findings indicate that only 10% of industries treated and disposed their wastes whereas 90% didn’t treat industrial wastes but disposed to the environment. The major observed impacts were on: affecting human and animals’ health, pollute surface and groundwater, pollute soil and air, trigger firing, damage ditches, block canals and cause over floods, among others. It requires concerted efforts to minimize and avoid improper waste disposal systems so as to realize economically active, environmental suitable and socially conduce capital city for its residents, tourist and business people.

The use of recovered paper as a raw material for paper production is by far the most economical and ecological strategy for the disposal of waste paper. However, paper production from recovered paper furnish generates a great amount of residues, and the higher the demand requirements for the end product, the higher the amount of rejected material. The reason for this is that the selectivity of the deinking process is limited; therefore, some valuable components are also lost in reject streams. The rejection of usable components affects the economics of recycled paper production. As the cost of waste disposal continues to increase, this issue is becoming more and more severe. This paper summarizes the current state of the resource efficiency in recycled pulp production and provides information on the volumes of rejected streams and the usable material within them. Various means to use these reject streams are also discussed, including the main findings of a recent thesis by the main author. This review summarizes current internal and external use of reject streams generated in the deinking operations.
