The high freshwater consumption requirements in shrimp biorefinery approaches represents one of the major drawbacks of implementing these technologies within the shrimp processing industry. This also affects the costs associated with the plant operation, and consequently, the overall economic performance of the project. The application of mass integration tools such as water pinch analysis can reduce frewshwater consumption by up to 80%, contributing to shrimp biorefinery sustainability. In this work, the economic evaluation and the techno-economic sensitivity analysis for a mass integrated approach for shrimp biorefinery were performed to determine the economic feasibility of the project when located in the North-Colombia region and to identify the critical techno-economic variables affecting the profitability of the process. The integrated approach designed to process 4113.09 tons of fresh shrimp in Colombia reaches a return on investment (%ROI) at 65.88% and a net present value (NPV) at 10.40 MM USD. The process supports decreases of up to 28% in capacity of production and increases of 12% and 11% in the cost of raw materials and variable operating costs without incurring losses, respectively. These findings suggest that the proposed design of the water recycling network coupled to a shrimp biorefinery approach is attractive from an economic point of view.

Wind power technology is developing rapidly in China. Especially in the north of China, decentralized wind power (DWP) has developed rapidly. However, wind curtailment exceeds 4% of the gross generation, which has become an important obstacle restricting the development of DWP in 2019. Technical schemes are effective solutions to promote decentralized wind power consumption (DWPC). Moreover, there are few economic analyses of DWP projects with key technologies. This paper summarizes the typical technical schemes and analyzes the economy of a DWP grid-connected project with typical technical schemes by combining methods of the net present value (NPV) and real options (RO). It appears that the DWP project can be profitable with an NPV of about CNY 4.3721 million and an option value of CNY 16.6022 million in the case of a feed-in tariff of 0.34 CNY/kWh. Feed-in tariff and equipment investment costs are the most relevant parameters for economic feasibility according to the sensitivity analysis. Furthermore, 30.73 million kWh connects to the Mengxi grid each year. The project has an annual maximum CO2 emission reduction of about 31 thousand tons and an SO2 of about 0.1 thousand tons. In addition, it also realizes fine social benefits, including the support of local residents and the improvement of local new urbanization levels. Finally, this paper puts forward policy suggestions for the development of DWP mainly from an economic point of view.

The purpose of this study is to analyze the production of copper nanoparticles (Cu NPs) on an industrial scale in an engineering perspective and economic evaluation perspective. Energy is needed because of various energy related applications. Evaluation of Cu nanoparticle production in an engineering perspective is carried out from the selection of processes that are adapted to industrial scale, calculation of mass balance, to the adjustment of commercially available equipment. Evaluation of production from an economic point of view is done by calculating economic parameters: Gross Profit Margin, Internal Return Rate, Payback Period, Cumulative Net Present Value, Profitability Index, and Break Even Point. Briefly from the production process, we use Copper acetate hydrate (CuAc2.2H2O) (as a source of Cu), Tween 80 (polyoxyethylene-(80)-sorbitan monooleate) and ethylene glycol (as a reducing agent). The engineering viewpoint shows this process is capable of producing Cu nanoparticles which can be used as conductive nanoionic. Economic evaluation determines the process is beneficial, discussing with positive values ​​all economic parameters. However, for some variations this process is not profitable, so economic evaluation is needed.

The purpose of this study was to analyze the Fluoride Tin Oxide (SnO2/F) production in home-scale industry in engineering point of view and economic evaluation perspective. This material is considered due to its wide range of energy-related applications. Evaluation of the SnO2/F production in engineering perspective is conducted from the selection of the most economical process, mass balance calculation, to the adaptation in the commercially available apparatuses. Evaluation of the production from the economic point of view is done by calculating economic parameters: Gross Profit Margin, Internal Rate Return, Payback Period, Cummulative Net Present Value, Profitability Index, and Breakeven Point. In short of the production process, we used the pure tin (as the metal precursor) and ammonium fluoride (as the source of Flouride for doping). The engineering point of view showed that the process is able to produce conductive glass that can be used as the active electrode substrate in the solar cell. Economic evaluation showed that the process is profitable, confirmed by the positive values from all economic parameters. However, for some cases that are compared to the market and the local bank interest, the process is not attractive for investor. Thus, to make them attractive, support from government or corporate social responsibility is required.

We have viewed a business in the south of the Great Plain Region from an economic point of view in 2004-2005. The main activity there is pear growing and storage. Four varieties of different time of ripening and storing are grown there. We have measured all the relevant activities, worked out a local normative and prepared a detailed technology. The economic evaluation was based on this data. Activities, like disinfection, pre-storage disinfection and selection, in-storing and out-storing, classification after storage, packaging, as well as loading trucks, were monitored by variety. Storage loss was determined and widely varied according to varieties, length of storage and time of out-storing. Different varieties resulted in different quality classes after storage. Price depended on the quality classes. Economic evaluation was carried out when all the relevant costs and revenues were known. Fixed and variable costs of storage were determined, break-even point was calculate and the market position of the product was evaluated.

The influence of distillery stillage doses on the yield of wheatgrass hay on agrochemical properties of soils in general is considered in the article. The most effective dose of distillery stillage under existing conditions is revealed. Nitrogen is the decisive factor for the yield of the crops. Widespread deficiency of nitrogen represents scientific and practical interest for the agro-chemistry studying transformation of nitrogen in soil-fertilizer-plant system for the purpose of increase in efficiency of crops quality in the biological relation. Increase in the main production of distilleries and conse-quently in waste products of the spirit industry, low demand from cattle breeders on the distillery stillage (feeding of cattle with distillery stillage is precisely connected with seasons, i.e. it is fed, mainly, during the stall period) has led to the fact that nearly 50% of it could not be sold. Development and deployment of new waste-free technologies of production of alcohol will demand a lot of time and expenses, and the unused stil-lage comes to ponds stores daily which are gradually overflowed that endangers the ecological condition of croplands and open reservoirs, adjacent to distilleries. Moreover, long storage in ponds leads it to spoiling, stratification and formation of a ground deposit. Therefore the problem of stillage utilization is very actual now and demands an integrated approach to its consideration as it has to be considered in the economic point of view, and from compliance to requirements of the nature protection legislation. One of the solutions of the problem stillage utilization is its application in agriculture as fertilizer. In Ukraine, the grain bards resources are quite significant, given the volume of alcohol SE Ukrspirt. The volume pislyaspyrtovoyi bards on modern technology is per 1 dm3 alcohol 11 ... 13 dm3 bards. However, it can be stored quickly sour, costly transportation to the consumer. Reset distillery bards in the river leads to significant environmental degradation. It solids accumulate in water pipes and riverbeds, decompose and pollute the environment. To build bards were repositories (filtration fields), which naturally occurs mechanical, chemical and biological treatment of waste. In bioshari formed in a layer of filtration load, the sewage draining into the ground, organic matter biodegradable. This mechanism is similar to the process of composting cut vegetation, household food waste and so on.

Article is devoted to the description and the analysis of the system-dynamic model of technological process of biogas production from multicomponent vegetable raw materials. A research objective – optimization of biogas production process from vegetable raw materials by methods of imitating modeling, finding of the optimal regimes of the simulated production cycle – the best ratio from the economic point of view between an exit of biomethane and rates of giving/replacement of the initial substratum depending on the composition of raw materials.In article models with a discrete and continuous cycle of production are considered, the description of the similar realization executed in the environment of multiapproach modeling of AnyLogic for model of technological process of anaerobic digestion of non-uniform multicomponent vegetable biomass is provided.The known stoichiometric model of production of biomethane is taken as a basis, her modification is made for a case of multicomponent raw materials (percentage division into conditional components – sugar, lignin and cellulose). Possibilities of modern software shells and environments of modeling in tasks of the complex analysis and optimization of the studied process are shown.During the conducted researches a row of non-trivial results on a choice of optimum parameters of an operation mode of the model bioreactor is received. For a case of the discrete process of up-dating of contents as parameters of optimization the frequency and a level of up-dating, and for the continuous flowing system – channel speed were selected.It is shown that the optimal values of the parameters from the point of view of the integrated output of the biomethane lie close to the cloud of critical acidification, which leads to the stoppage of the process. If the economic indicators are chosen as an optimization criterion, then we obtain optimal values of the parameters lying within the region of stable functioning of the model bioreactor.

The products from paper are widely used materials with several benefits. The corrugated paper keeps items protected through long-distance logistic processes and constant shipping and handling. The corrugated boxboards are ideal options for any industry’s shipping, packaging and storage needs. Papers and cardboards are quite low cost and also provide environmental-friendly solutions, using recyclable materials such as used corrugated cartons and old newspapers. Recycling offers a reduction in environmental impact in densely populated regions and a large production of paper and board products. Generally, the use of recycled fiber produces paper with poorer mechanical properties due to the decrease in the interfiber bonding. The recycled pulp must be treated to restore its bonding strength, for which there are six methods possible: mechanical treatment, chemical additives, chemical treatment, fractionation, papermaking process modification and blending with virgin fiber. Although some mills produce 100% recycled paper, the majority augment their used pulp with some virgin fiber. Paper properties can be tailored within some ranges by modifying the properties of fibers, but the influence of fine quality on structure, strength and optical properties of paper can be even greater. The properties of papers are essentially determined by their raw materials. Most of these raw materials are made from 100% recycled fiber, but as the quality of the waste fiber varies, different chemicals must be used to provide the desired or expected properties. From an environmental and economic point of view, the use of primary fibers can be an alternative.
