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 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.

The aim of this study is to evaluate the economic and engineering layout carried out on a factory scale LiFePO4 production using the hydrothermal synthesis method. The method used is economic evaluation by calculating gross profit margin (GPM), payback period (PBP), break-even point (BEP), internal rate return (IRR), cumulative net present value (CNPV), return on investment (ROI). , and the profitability index (PI). LiFePO4 was synthesized using precursors FeSO4.H2O, ascorbic acid and H3PO4 and then reacted with LiOH2.2H2O by maintaining the Li: Fe: P molar ratio of 3: 1: 1. The results of GPM and CNPV calculations from the manufacture of industrial scale LiFePO4 show that the payback period (PBP) has increased in the fourth year. LiFePO4 applications on an industrial scale can be used for lithium ion batteries.

The Impact

This study aims to analyze the economic evaluation on the production of TiO2 nanoparticles using the simple aqueous peroxo route method. Economic evaluation is carried out using several economic parameters, such as Payback Period (PBP), Break Even Point (BEP), and Cumulative Net Present Value (CNPV). The economic evaluation method is carried out by calculating several factors to see the potential of TiO2 nanoparticle production, such as an increase in tax prices, sales prices, and the effect of raw material prices. Based on tax evaluation, the greatest income achievement when taxed is 10%. Based on the sales evaluation, the minimum sales price so that the company does not lose is at the 90% point. Based on variations in raw material prices, an increase in raw material prices by up to 50% will not cause a loss. PBP analysis shows the investment in a short period of time, namely in the fourth year and until the 20th year the company's profits continue to increase. In conclusion, the results of the economic evaluation show good prospects. The impact of this research is the evaluation of large-scale economic data on TiO2 nanoparticles, production prospects with estimated factors that may occur under ideal conditions.

Biogas is a promising renewable energy resource produced by using anaerobic digestion of organic substrates and it is mainly used to generate electricity by means of biogas engines. Other potential utilisations are growing, e.g. grid injection and biofuels production but, generally, a treatment aimed to increase its quality is mandatory and greater investments are generally required to produce upgraded biogas (biomethane). Despite the increasing of interest on these applications, a lack of information is still present from an economic point of view. The present paper performs an extended economic assessment of upgrading and selling biogas starting from a typical farm-based anaerobic digestion plant in Northern Ireland assumed as reference. Several economic indexes have been considered to assess the economic performance of the upgraded anaerobic digestion plant, namely net present value, pay-back period, profitability index and internal rate of return. Moreover, different scenarios in terms of fossil fuel prices have been analysed. The results show that producing and selling biomethane can be economically feasible if an adequate market is fostered. Optimum anaerobic digestion sizes between 26.9 and 64.4 tonne/y have been found, with correspondent net present value and pay-back period values in the range of £6.7–64.4M and 2.8–7.5 years, respectively, depending on the price scenarios analysed and the economic index chosen. Generally, adopting the net present value as objective function of the optimisation leads to greater anaerobic digestion size than the other indexes for any price scenarios considered. Finally, tougher market conditions (i.e. higher fossil fuel prices) lead to better economic performances of the upgraded anaerobic digestion configuration.

Biomethane is a renewable gas produced by the transformation of organic matter. It can lead to emissions reduction and it contributes to increasing methane production. Incentive policies favour its development and for this reason, the objective of this paper is to investigate the economic performance of biomethane plants and their process monitoring by electronic systems. Mathematical modeling is here presented to study the financial feasibility of biomethane plants in function of the size (100 m3/h, 250 m3/h, 500 m3/h, 1000 m3/h), the feedstock used (organic fraction of municipal solid waste and a mixture of 30% maize and 70% manure residues on a weight basic) and the destination for final use (fed into the grid, destined for cogeneration or sold as vehicle fuel). From an economic point of view the plant performance is studied by economic tools as Net Present Value and Discounted Payback Time and the uncertainty analysis is implemented using Monte Carlo method. Moreover, from a technical point of view, process monitoring is analyzed to understand what happens in a biomethane plant and help to maintain a stable process. The results show that the profitability of biomethane plants is verified in several scenarios presenting losses only if subsidies were removed.

As an application of probabilistic fracture mechanics (PFM) and a financial method, a risk-benefit model was developed for the purpose of optimizing maintenance activities of steam generator (SG) tubes used in pressurized water reactors (PWRs). To justify whether or not it is worth while implementing the selected maintenance strategy in terms of an economic point of view, net present value (NPV) was calculated as an index which is one of the most fundamental financial indices for decision-making based on the discounted cash flow (DCF) method.
