Abstract The discharge of water from oil fields It has become one of the most significant environmental concerns associated with the oil sector. Hydrocarbon spills and crude oil fuel spills are a continual hazard to aquatic ecosystems. Inexpensive and sustainable sorbent materials are needed to mitigate the environmental damage of this pollution. To meet this need, this study features a low-density polysulfide polymer prepared by Sulfur and used cooking oils react directly. Since both sulfur and cooking oils are hydrophobic, the polymer is close to hydrocarbons such as crude oil and diesel fuel and can easily remove them from seawater. Oil can be recovered and polymer can be reused in oil spill treatment. Polysulfide is unique in that it is prepared from completely recycled waste. Sulfur is a by-product of the petroleum industry, and used cooking oil can also be used as a raw material. Therefore, waste sulfur from the petroleum industry is used to make effective anti-pollution adsorbents from the same sector According to the study’s findings, 98.55 percent of the oil was removed from the north.

It has been discovered that absence of education and security in any society gives room to lawlessness and crises. This paper brings to bare the effect of waste collection and management on poverty reduction. Polythene is a by- product of crude oil. It is otherwise known as polyethylene. The use of polythene in the society is enormous and when poorly managed, constitutes at least 40% of the wastes that accumulate in the municipal. This paper views waste collection and management especially polythene as a tool for reducing poverty in the society. The emergence of recycling industries provided the platform for re-use of polythene materials thereby, making it an industrial raw material for some industries.

The nicotine, reducing sugar and ion contents from the threshing of tobacco can re-used from the industry. The crude oil and fatty oil compositions of tobacco seeds can be considered as an alternative source of raw material for biodiesel. In this study, the nicotine, reducing sugar content, crude oil, fatty acid composition and ion content were determined in 29 genotypes and 1 cultivar of tobacco. The genetic diversity was determined among the tobacco cultivar and genotypes base on examined properties. The nicotine content varied between 0.10-0.87%, reducing sugar ranged from 9.70-21.30%, crude oil varied between 24.33-47.00% and fatty acid compositions was found in the range of 77.94-100%. Linoleic (13.92-75.04%) and butyric (0.33-64.98%) acids were the major components. Overall, the BSR-5 (52.56 mg/g) and ESR-5 (44.58 mg/g) genotypes exhibited the highest potassium contents and ESR-7 (6.54 mg/g) and ESR-8 (1.28 mg/g) genotypes had the lowest chlorine contents. As a result of this study, the highest nicotine content, reducing sugar and crude oil of tobacco were found in ESR-4, ESR-11 and BSR-5 genotypes, respectively. The dendrogram analysis divided the tobacco into two main groups and most of the same origin genotypes fell into the same group. The results indicated that the different tobacco leaves and seeds can be evaluated as an alternative source in the industry as cigarettes, biodiesel and different industrial applications such as cosmetic, oil paints and varnishes based on their chemical properties.

Lemon growing areas in the north of Argentina have industries that produce concentrated juice, peel and essential oil and generate a significant amount of liquid and solid waste as lemon pulp. In Argentina, despite the potential applications that the pulp has as animal feed and human and industrial raw material, only 10% is used for these purposes and the rest is discarded into the environment causing many ecological and economic problems. There is little information in the literature on biotechnologies for the treatment of this industrial waste. This paper shows that lemon pulp is a suitable substrate to be treated by anaerobic digestion. We obtained 86 and 92% reduction of chemical oxygen demand in a digester with a semi-continuous feed and retention time of 10 and 20 days respectively and a productivity of 0.406 g CH4/g VS h. Comparative tests showed that pre-digesting the pulp improved the process of digestion and increased biogas generation by 20%.

The sub-optimum conditions of Nigeria conventional refineries remains a drastic setback since all other industries are intertwined with its outputs. It is noted that amidst all other glaring contributing factors as listed in the study, insufficient large capital funds on the part of private investors and vandalization of pipelines seems to be conspicuous. The stolen crude oil got from the pipelines serve as the beginning point for illegal refining. Asides the issue of quality control of products, their sub-standard operation also affects Nigerians environmentally and economically. The more the Government invest time and resources to stop their operation; the more they spring up like mushrooms. This paper reflects the authors view on achieving a win-win scenario. The upgrading of existing illegal refineries at strategic locations within the country to standard modular refineries seems to be a more feasible and friendly approach. The issue of channeling of intermediate products can be solved through the introduction of clusters, where final products of one become raw material for the other. Intermediate products can also be channeled to Government owned conventional refineries for further processing. From analysis, it is deduced that overall design capacities from clusters have optimum effect on the intermediate environment in terms of meeting demand. Extensive operational training on crude oil refining will help buttress the point while Transfer of Knowledge from official vendors to Nigerian Engineers on how to fabricate modular refining units locally will also help to reduce overall cost.

In the farms of the north-eastern slope of the Greater Caucasus wood raw material obtained from intermediate felling, is not fully utilized and is not effective, due to the organizational and technical difficulties of farms. In addressing these issues in 8 directions of the region with a length of 40-50 km 14 intermediate assembly points were organized, which are intended for the collection and temporary storage of wood raw material harvested within a radius of 15-20 km of the forest. Need to establish assembly points is due to the complexity of relief items and the possibility of year-round use of the main roads of regional importance. To ensure uninterrupted timber industry and in full at the assembly point accumulated wood raw material is partially sorted. Processing of harvested wood raw material is planned for timber industry, located near the central region of the main road in the territory of Cuba town. Establishment in the area of the complex is considered justified, since the resource base in the coming years for intermediate, and later for the main use will be more than 100 thousand hectares of forests in the region. In the proposed area for the industrial complex for processing of raw wood there are all the technical and economic prerequisites. Accumulated in the assembly points wood raw material to the point of processing is transported using self-loading lumber carriers of up to 8 meters length, which is associated with a complex terrain conditions and road network in the region. This complex is planned to organize the following process areas: sawmills, parquet and packaging, small-chip technology, processing of technical greenery. In organizing the production sites size and quality characteristics and volumes of each category of harvested wood raw materials are taking into account, as well as the need for forest products in the region and the country as a whole. In the processes it is envisaged to use the most advanced modular processing of wood with the release of standard lumber, wood workpieces of different products, pulp chips, wood greens and products of its processing.

During the research conducted at the All-Russian Research Institute for Starch Products there has been developed a technological mode of using cellulolytic enzymes to reduce the viscosity of grain pulp obtained by grinding naked oat grains soaked in a sodium metabisulphite solution. As the experimental data had been processed, the optimum technological parameters of the process were determined: the consumption of the enzyme preparation Viscoferm was 200 g/t of grain and the dura-tion of fermentation by constant stirring for 2.5 hours at pH 4.6 and temperature 50°C. Under laboratory conditions there has been studied the possibility of starch processing of naked oat grain samples Vyatka, Percheron, 857h05, 766 h05 varieties grown in the Federal Agricultural Research Center of the North-East named N.V. Rudnitsky. Technological assessment based on grain processing in the laboratory using the “plant on the table” method has shown that the yield of coarse-grained starch A in the processing of naked oat using cellulolytic enzymes is 51.4-53.9%, i.e. higher than that of filmy oats, rye Falenskaya 4 and Vyatka 2, wheat and triticale. Low starch content in fiber (7.7-8.7% dry substances DS of fiber) was found in comparison with the results obtained from the processing of filmy oats, Falenskaya and Vyatka 2 rye varieties, wheat and triticale (11.2 - 13.9% DS of fiber). Fiber output by the processing of naked oats is 7.3 - 8.8% DS of grain, by the processing of other types of grain 10.3 - 17.5% DS of grain. The yield of small-grain starch B in the processing of the studied varieties of naked oat is 19.2 - 20.8% DS of grain, that is higher than this value obtained by processing of filmy oats and wheat, but lower than by pro-cessing of rye and triticale. Isolated carbohydrate-protein concentrate, including starch B and proteins, is recommended for use with the extract and fiber as a component for the production of feed.
