Microplastics particles (MP) are plastic with dimension less than 5 mm. Due to the fact that MP has very persistent chemical structure and it is very hard to degrade it;its occurrence in the environment is common and pollution from MP is increasing rapidly. One of the possible solutions is biodegradation with targeted bacteria culture. In this research it was experimented if bacteria culture Bacillus cereus will degrade MP particles of PVC. During the 30 days of experiments, it has shown that number of bacteria has grown which indicated that biodegradation occurs. In the experiments where bacterial growth is indicated most significantly peak of C=O functional group increased while peaks of stretching functional groups decreased. As monitoring of MP during the process and in complex matrix (wastewater) is not possible, modeling approach was used as an alternative. Developed model for predicting biodegradation was used MLP-ANN with 4 hidden nodes. This model show good predicting power as R2 of validation set is 0.983. With this developed model it is possible to predict stage of biodegradation and in future it is possible to simulate biodegradation of microplastics in aquatic ecosystems. © 2022 IEEE.

Given the urgent need to mitigate increasing CO2 emissions and alleviate the climate crisis, amine-based post-combustion capture (PCC) processes have emerged as a prominent method to reduce the emissions from industrial point sources. While many technological advancements have been introduced for such processes, leading to decreased energy requirements for capture, there are still only a few commercial installations because of their high costs. Therefore, these processes can benefit from process optimization to enhance their economic viability. This work presents a new open-source, rate-based, equation-oriented model of a novel PCC process that uses piperazine as the amine solvent. The proposed non-convex model can be used for both simulation and optimization and, to ensure its robust convergence, we further devise a custom-made, multi-level cascade initialization scheme. The model was validated with published pilot plant data and then optimized for pilot and commercial scales with an economic objective that considers both capital and operational costs. Results show that process optimization can indeed improve the economics of this technology, leading to 24.5% yearly savings at the pilot scale compared to the baseline case considered in the study. Additional parametric analyses were performed to understand how the flue gas flowrate and CO2 concentration, as well as the target capture rate, affects the cost of capture. © 2024, The Authors.

We aimed to quantify the bioactives (natural preservatives and functional substances) from agro- and food industrial waste streams and offer technological solutions to produce value-added products from agro-food wastes. Extracts with potent antioxidant properties were obtained from lavender steam- and hydro-distilled residues, sea buckthorn stalks and from swept walnut tree- and freshly collected black mulberry leaves. The applied methods (Soxhlet-, stirred-, and ultrasound assisted extraction), solvents, and process parameters of extraction (extraction time, temperature and feed-to-solvent ratio) were optimized for all waste sources aiming for the highest extraction yield with the highest concentration of the targeted bioactives in the extracts. The antioxidant activity of extracts was analyzed by the DPPH method in the presence of 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical. The content of total phenolics was quantified using Folin-Ciocalteu’s phenol reagent. Individual phenolic compounds were quantified by HPLC and LC-MS/MS. The antioxidant activities correlate well with the total polyphenol contents. The extracts of sea buckthorn stalk, lavender steam distilled residue and walnut leaves showed as strong antioxidant activities as the synthetic alternatives (BHT, BHA). Extracts from sea buckthorn stalk exhibited strong antibacterial activities in standard in vitro antimicrobial tests in the presences of different strains of Gram-negative and Gram-positive bacteria. © 2020, ETA-Florence Renewable Energies.

Modular process plants enable the process industry to adapt to volatile and fluctuating markets. The preferred process technology concept for these market scenarios is realized through combining pre-engineered process equipment assemblies (PEA) from different manufacturers with standardized interfaces. While the flexibility gain for this type of plants is high, the design of the safety systems of these modular plants in terms of exchangeability and compatibility is challenging. One solution could be the development of a safety-interface for PEAs to create flexible and scalable safety systems. The principles of modular basic process control are analyzed and requirements with respect to safety design are discussed. The authors provide a differentiation of the intramodular safety concept of a single PEA from the intermodular safety concept of a complete modular plant. A concept for safe and modular interaction of PEAs in a modular plant is developed and additionally validated on a basic demonstrator. Finally, from these findings, standardization requirements are provided and aspects for further research are pointed out.

Size reduction is essential for converting biomass into bio-fuel. It is usually performed using milling machines which consume large amount of energy. Steam explosion treatment which consists of auto-hydrolysis and rapid decompression steps, is a promising pre-treatment process to open up biomass fibers and to recover useful compounds from it. Numerous studies have investigated the effect of steam explosion on biomass composition and on bioethanol production. However, few studies have been conducted to investigate its effect on the reduction of biomass size. In this study, the effects of steam explosion conditions such as temperature and retention time, and type of biomass (hardwood and softwood) on biomass size reduction were investigated in detail using batch-type steam explosion equipment. Sakura (Prunus spp, hardwood) chips and Japanese cedar (Cryptomeria japonica, softwood) chips of 5-10 mm were used in this study. The treatment intensity is determined by a severity factor, which is established as correlation between process temperature and residence time. A rapid increase in the yield of solid biomass of size below 1 mm (fine particles) was observed when the severity factor was above 4. 2. The fraction of fine particles crossed 80%, when the severity factor was 5. 2. We concluded that temperature/pressure significantly influences biomass size reduction and that residence time and biomass type also influence biomass size reduction, particularly at lower severity (5.2). © 2016 ETA-Florence Renewable Energies.

Near infrared (NIR) instruments in combination with multivariate data calibration models are useful tools in process monitoring. However, the need for expert assistance with calibration and maintenance of the models is a bottleneck limiting their more widespread use. In the previous article [NIR news26(8), 13–16 (2015)], the MATLAB graphical application called Fulgur was introduced. Fulgur was developed as part of the BIOPRO “Hands Free” project with the goal of developing automated methods for handling data sets and calibrations of partial least squares models for NIR instruments. In this article, the Model-View-controller programming design principles needed for developing the application are described in more dept. as an introduction for potential developers who may want to use and expand the Fulgur framework. The programing design principles may also be of interest to chemometricians who want to program and develop their own GUI applications in MATLAB. The source code for the application together with more in-dept. user and developer guides and tutorials for programming plugins is available for download from ***.
