Survey Review

The implementation of sustainable water management practices, through the recycling and reuse of water, is essential in terms of minimizing production costs and the environmental impact of the food industry. This problem goes beyond the classical audit and housekeeping practices through developing a systemic water-using reduction strategy. The implementation of such an approach needs R&D development, especially for the food industry, where there is a lack of knowledge on: (a) process integration and (b) data on the pollutant indicators or (c) volumes of water used and discharged at specific steps of the food processing line. Since energy pinch analysis emerged, different variations of pinch methods have been developed. As a variation of pinch, Water pinch analysis is a global and systematic approach to minimize water consumption and discharges, especially for the most energy-intensive and water-consuming factories. Based on the nature of the food industry, the real systems are complex, multi-source multi-contaminant systems, the problem should be well formulated, including mathematical constraints (inequalities thresholds). Current work has reviewed comprehensive literature about different variations of pinch analysis. In continue, water pinch method deeply discussed and some relevant data concerning the water using process and pollutant indicators have been reviewed with emphasis on the food industry sector.

Wirus SARS-CoV-2 zaczął się rozprzestrzeniać na całym świecie już kilka tygodni po jego wykryciu. Wszyscy są zaniepokojeni skutkami, jakie może spowodować pandemia COVID-19 wywołana przez ten wirus. Celem artykułu jest ocena wpływu pandemii na sektor przetwórstwa spożywczego i eksport rolno-spożywczy Polski. W opracowaniu przedstawiono uwarunkowania sytuacji, w jakiej znalazł się polski sektor spożywczy w przededniu pandemii, zanalizowano niektóre dane produkcyjno-finansowe i handlowe za kilka miesięcy jej trwania oraz wskazano ewentualne następstwa pandemii i możliwe kierunki zmian w sektorze. Z analizy wynika, że sektor dość dobrze radzi sobie z kryzysem wywołanym przez pandemię COVID-19. Skutkiem pandemii nie powinna być duża fala upadłości i bankructw przedsiębiorstw, a jedyną negatywną konsekwencją może się okazać czasowe spowolnienie rozwoju sektora, głównie w wyniku wahań dynamiki wzrostu polskiego eksportu rolnospożywczego. Rosnący popyt w kraju i za granicą oraz wciąż niższe w porównaniu z innymi krajami koszty produkcji w Polsce pozwalają na utrzymanie tendencji wzrostowej produkcji i eksportu produktów rolno-spożywczych, a co za tym idzie wciąż dobrą kondycję sektora. Odpowiednia polityka gospodarcza i zaangażowanie przedsiębiorców mogą również pomóc utrzymać dotychczasowy poziom rozwoju polskiego sektora żywnościowego. Słowa kluczowe: eksport rolno-spożywczy, pandemia COVID-19, przemysł spożywczy, wirus SARS-CoV-2. The SARS-CoV-2 virus began to spread worldwide just weeks after its detection. Everyone is concerned about the effects of the COVID-19 pandemic caused by this virus. This article aims to assess the impact of the pandemic on the food processing sector and Polish agri-food exports. The article outlines the determinants of the situation in which the Polish food sector found itself at the eve of the pandemic, analyzes some production, financial and commercial data gathered during several months of its duration, and indicates possible consequences of the pandemic and potential directions of changes in the sector. The analysis shows that the sector is coping fairly well with the crisis caused by the COVID-19 pandemic. The pandemic should not result in a massive wave of business insolvencies and bankruptcies, and the only negative consequence may be a temporary slowdown in the sector’s development, mainly due to fluctuations in the growth dynamics of Polish agri-food exports. The growing demand in Poland and abroad and the still lower production costs in Poland compared to other countries allow for the maintenance of the upward trend in the production and export of agri-food products, and thus the continued favorable condition of the sector. Appropriate economic policy and the involvement of entrepreneurs may also help maintain the current level of development of the Polish food sector. Keywords: agri-food exports, COVID-19 pandemic, food industry, SARS-CoV-2 virus.

Heat Exchanger Network

Energy conservation has recently become one of the most important considerations in industries, especially in petrochemical industries. This is due to the limited availability of fuel which affects the price of energy sources, as well as the tightening of the regulations concerning environmental and social issues related to pollutant emissions produced by industries. The successful energy-saving efforts made by industries impact on not only lowering production costs but also indirectly preserving natural resources as well as reducing the pollution of CO2 which is one of the gases contributing to global warming. Pinch analysis has been widely known for process integration, especially in heat integration, in order to gain energy efficiency and cost efficiency in many industries for decade. The analysis allows selection of efficient heat exchanger network with minimum hot and cold energy requirement. By using pinch analysis, the number of heat exchanger units required could also be minimized which leads to the optimum cost of operational and investment. Pinch analysis is also allowing for the investigation of any pinch problems, such as pinch threshold problems, cross pinch problems, and problems related to incorrect placement of utilities which impacted to the wastefulness of energy consumption. Despite many success studies of highly potential saving of heat integration through pinch analysis, the real implementation of efficient and effective heat exchanger network (HEN) based on pinch analysis is still facing difficulties, for example in term of flexibility and controllability of operation.  This paper provides preliminary information in increasing energy efficiency or energy savings when utilizing pinch technology considering operability and flexibility of its operation for retrofitting units for chemical industrial plants.

Program of acceleration of local resource based diversification of food consumption (P2KP - BSL) has nationally implemented as the initial stage for program socialization since 2009 and simultaneously implemented in 2011. This is a descriptive study. Districts of Sekarbela, Selaparang, and Ampenan were selected as the research focused-areas considering that the three districts have already implemented three sub-programs of P2KP – BSL that are; a) Sub-program of Optimizing Courtyard Utilization, b) Sub-program of Food Processing, c) Sub-program of Consumption Campaigns of Diverse Food, Balanced Nutrition, and Safe for School Children. Finding of the study in Mataram town shows that there are seven planned sub-programs of P2KP – BSL; however, due to the limited fund, there only three sub-programs; sub-program of Optimizing Courtyard Utilization, sub-program of Food Processing, and sub-program of Consumption Campaigns of Diverse Food, Balanced Nutrition, and Safe for School Children have been realized . Meanwhile, there are four other unimplemented programs; 1) sub-program of Specific Region Food Production Developments, 2) sub-program of Local Food Lift, 3) sub-program of Food Business Development and SMEs, and 4) sub-program of Agro-Food Industry Development. Government has effort to change people's habits aiming to reduce the rice consumption and started to diversify food consumption through a variety of ways - dissemination through print media, electronic media, trainings, and field schools.

The invasive fruit fly Bactrocera dorsalis poses a major threat to the production and trade of mango in sub-Saharan Africa. Farmers devise different innovations to manage the pest in an attempt to minimize yield loss and production costs while maximizing revenues. Using survey data obtained from Embu County, Kenya, we analyzed farmers’ knowledge and perception as regards the invasive fruit fly, their innovations for the management of the pest, and the determinants of their adoption and dis-adoption decisions of recently developed and promoted integrated pest management (IPM) technologies for suppression of the pest. The results show that farmers consider fruit flies as a major threat to mango production (99%) and primarily depend on pesticides (90%) for the management of the pest. Some farmers (35%) however use indigenous methods to manage the pest. Though farmers possess good knowledge of different IPM strategies, uptake is relatively low. The regression estimates show that continued use of IPM is positively associated with the gender and education of the household head, size of a mango orchard, knowledge on mango pests, training, contact with an extension officer, and use of at least one non-pesticide practice for fruit fly management, while IPM dis-adoption was negatively correlated with the size of the mango orchard, practice score and use of indigenous innovations for fruit fly management. We recommend enhancing farmer′s knowledge through increased access to training programs and extension services for enhanced adoption of sustainable management practices for B. dorsalis.

Teff is an important crop for smallholder farmers in Ethiopia. Improved crop management practices are needed to increase teff productivity and decrease production costs. Here, we used a split–split plot design to evaluate the impacts of different tillage, sowing, and soil compaction practices, and their combinations, on agronomic performance, weed population, lodging, and cost in teff production at the Aba Gerima watershed in northwestern Ethiopia in 2018–2020. Reduced tillage (RT) improved soil moisture, resulting in increased agronomic performance and decreased production costs compared with conventional tillage (CT); however, the weed population was substantially larger with RT than with CT. Row planting (RP) reduced seed cost and lodging but increased sowing and weeding costs compared with broadcast planting (BP). Plant population and leaf area index were substantially greater with BP than with RP during early-stage growth, but this reversed during late-stage growth. Despite labor costs being significantly greater with (WC) compaction than without (NC), little to no differences were observed in the weed population or in agronomic performance. Partial cost–benefit analysis revealed that RT–RP–WC followed by RT–RP–NC was the most economical treatment combination, suggesting that RT–RP–NC could be a labor-effective means of increasing teff production by smallholder farms in Ethiopia.

Key Steps

Chemical processes are energy intensive industries; the majority of energy consumed in industrial processes is mainly used for heating and cooling requirements. This results in increasing the interest in obtaining the optimum design of the heat exchanger networks to reduce the energy consumption and face the growing energy crises. Most of the published literature over the last fifty years promotes the process integration technology as a main part of the process system engineering science. Graphical Pinch Analysis method normally includes two key steps, firstly obtaining the energy targets which include the minimum energy required for the HEN design, then designing the heat exchanger network (HEN). This paper introduces a new graphical approach for the design of new heat exchanger networks (HENs) based on pinch analysis rules. The HEN is represented on a simple graph, where the cold stream temperatures are plotted on the X-axis while the driving forces for each exchanger are plotted on the Y-axis. This graphical technique can describe the energy analysis problems in term of temperature driving force inside the heat exchanger, which is an important factor in the design process as the differences in these driving forces are involved in calculating the area of heat exchangers, and consequently affecting the cost.

Planting densities influence several aspects of forest formation, including management practices, timber yield, quality, and extraction, and consequently its production costs. The objective of this study was to evaluate Mimosa caesalpiinifolia and Gliricidia sepium growth as a function of planting density (400, 600, 800, 1000, and 1200 plants ha-1) and plant age. The species were evaluated every 90 days for plant height (PH), crown diameter (CD) and root collar diameter (RCD) (10 cm above the ground), with the first evaluation performed at 90 days and the last at 720 days. When plants were one year of age and beyond, evaluations were conducted also for stem diameter at breast height (DBH) (1.30 m above the ground). A randomized block design with split-plots and three replicates was adopted. Species were assigned to plots, planting densities were assigned to subplots, and evaluation ages were assigned to subsubplots. The four traits in both species had their values decreased as planting density increased, but continually increased as plant age increased. For PH and RCD there was an alternation between species superiority, with gliricidia being superior to sabiá at some ages, while the opposite occurred at other ages. As to CD the species only differed in the last measurement, gliricidia being superior. With regard to DBH, gliricidia was superior starting from the second measurement. There was an effect of the species × ages interaction for the four traits and also an effect of the densities × ages interaction for CD and DBH.
