A growing number of manufacturers are realizing cost and environmental benefits through the sustainability of innovation and optimization processes. Based on polluting less and creating less, the study is pursuing sustainability on increasing operational efficiency by reducing costs and waste. Pulse dust collection systems are commonly used filtration equipment in industries and have lots of energy consumption due to running all day. This study is focused on the optimal parameters for energy saving and cost reduction, and the model is represented by the pressure drop of the filter and the residual powder. The characteristic values of the cleaning efficiency and the air permeability reduction are used for MATLAB to analyze the optimization state. This study found that the material of filter elements, the type of dust, the conditions of pulse-jet, and the filtering speed are the factors that affect the operational efficiency. In terms of cost, the pulse interval time in 10 s is the best parameter, and the pulse time does not affect the overall cost of the filter. Considering energy saving, 0.1 s of the pulse time is the best parameter. In addition, a lower dust concentration is a way to improve efficiency for increasing the filter life and reducing cost.

In this paper, a detailed description of a project designed to recovery and utilize waste heat in a cotton manufacturing enterprise in Shandong, Jin Mao Textile Co., Ltd(China) is presented: both energy saving and emission reduction(ESER) aspects have been thoroughly considered. First of all, an accurate analysis of the status of the previous cotton mill for production process was developed, to identify possible improvement opportunities; then an energy saving reformation of waste heat recovery in cotton mill was proposed and designed. After that, by means of a comprehensive feasibility analysis, the ESER indices were calculated assuring good environmental benefits of the plant modification investment. The modifications to the system make it possible to achieve consistent annual savings of coal, electricity and waste heat, CO2, SO2 emissions through effective recovery and utilization of the waste heat that was discharged into the atmosphere in the original production. Implementation of the reformation system fulfilled the waste heat recovery and utilization. And also create good environmental benefits.

Reclaimed Asphalt

The evaluation of energy savings in the area of transport infrastructure entails a complex characterization of factors, attitudes and consequences. In the frame of energy saving approach, must be identified sustainable alternatives and solutions for road asphalt pavements production and exploitation. Finding innovative materials is one major objective in this process. In the present paper has been carried out an evaluation of the energetically and environmental benefits of warm mix asphalt (WMA) compositions that incorporate reclaimed asphalt pavement (RAP) and their contribution to roads sustainable development. For a proper analysis and reliable results, have been used the Life Cycle Assessment methodology and asPECT software. WMA integrating RAP are known as energy – saving and environmentally friendly asphalt roads pavements. Analyzed in a comparative perspective with hot mix asphalt (HMA) incorporating RAP, WMA would gain in results due to the decrease in mixing and compaction temperature, energy consumption and emissions but also to the increase in durability, quality and performance. The results of this comparison intended to point out an alternative that would provide an increase in the sustainability of the transport infrastructure sector.

Abstract. In this paper, helium-assisted near-dry wire-cut electrical discharge machining (NDWEDM) method molybdenum wire has been used to reduce the environmental impact and to cut M2-HSS material. The pressurized non-reacting helium gas mixed with a small amount of water (Helium-mist) is used as the dielectric fluid to accomplish adequate cooling and flush-out debris. The new experimental setup has been developed to conduct the near-dry WEDM tests using the L9 orthogonal array of the Taguchi technique. The input parameters such as voltage (V), pulse-width (PW), pulse-interval (PI), and flow rate (F) of mixing water and output variables are the material removal rate (MRR) and surface roughness (Ra). It was observed that MRR and Ra are amplified by the rise in voltage and pulse-width, and flow rate conversely, the pulse interval minimizes the responses. The percentage of contribution of pulse width, voltage, pulse interval and flow rate are 24.06%, 32.98%, 12.75% and 30.21% on MRR and 20.94%, 22.22%, 47.86% and 8.97% on Ra respectively. Finally, the confirmation trials have been accomplished to validate the foreseen best parameter sets on optimal responses.

The research aims at studying the potential of reusing plastic water bottles as a building material and an alternative to traditional bricks, in a way that can minimize waste and hence reduce ecological imbalance. The research compares the energy performance of building with traditional bricks and building with plastic bottle blocks. The researchers built digitally two sample rooms: (3 meter width*3 meter length*3 meter Height) with both materials, Then they took on-site measurements for energy performance of the rooms. The rooms were built on DesignBuilder software in order to help in environmental analysis of buildings, and compare the efficiency of the two materials of sample rooms. Results showed that building with plastic water bottles has some environmental benefits other than reuse of a material that hardly decomposes. It has its effects on energy saving and thermal comfort. Further research and experiments is encouraged as the plastic residue dilemma grows more in modern societies and affects the ecological balance and wild life.

An Isolated Microgrid (IMG) is an electrical distribution network combined with modern information technologies aiming at reducing costs and pollution to the environment. In this article, we implement the Bacterial Foraging Optimization Algorithm (BFOA) to optimize an IMG model, which includes renewable energy sources, such as wind and solar, as well as a conventional generation unit based on diesel fuel. Two novel versions of the BFOA were implemented and tested: Two-Swim Modified BFOA (TS-MBFOA), and Normalized TS-MBFOA (NTS-MBFOA). In a first experiment, the TS-MBFOA parameters were calibrated through a set of 87 independent runs. In a second experiment, 30 independent runs of both TS-MBFOA and NTS-MBFOA were conducted to compare their performance on minimizing the IMG using the best parameter tuning. Results showed that TS-MBFOA obtained better numerical solutions compared to NTS-MBFOA and LSHADE-CV, an Evolutionary Algorithm, found in the literature. However, the best solution found by NTS-MBFOA is better from a mechatronic point of view because it favors the lifetime of the IMG, resulting in economic savings in the long term.

Power exchange needs to design a mechanism, which can achieve the internalization of environmental costs of power generation enterprises, thus maximizing the social environmental benefits. Two-stage optimization models of energy-saving and emission-reducing for coal-fired power plant are established. In the first stage model, maximums of the social environmental benefits and energy-saving effect are taken as the objective functions with consideration of the unit output constraints, load constraints and emissions constraints, etc. In the second stage model, maximums of power generation enterprises profits are taken as the objective functions with the constraints of KKT conditions of the first stage model. The proposed marginal incentive pricing mechanism not only controlls CO2 emissions from the total amount, but also improves emissions treatment initiative of coal-fired power generation enterprises. A numerical example shows that the proposed model and algorithm can achieve the effect of saving energy, reducing emission and encouraging competition during the process of generation.
