Life Cycle Assessment of Internal Wall Panels: A Case Study of Sumerbank Kayseri Textile Factory Restoration Process

This study presents a case study that aims to select the ideal internal wall panel option causing less environmental impact for the Sumerbank Kayseri Textile Factory restoration process, which is now used as part of Abdullah Gul University’s main campus. Since the university has an environmental agenda, examining the environmental impacts of the materials used for the ongoing restoration process has the potential to contribute to these goals. For this purpose, the three most used interior wall panels in the Turkish building material industry, gypsum, reinforced gypsum, and cement-based panels, were selected within the scope of the case study. The life cycle assessment (LCA) method was used to compare these options, and analyses were conducted using SimaPro software. The data required for life cycle impact assessment (LCIA) were obtained based on market analyses and also from the EcoInvent Life Cycle Inventory Database. At the end of the study, damage assessment, weighting, and midpoint and endpoint data of the characterization results provided by the ReCiPe method were compared and interpreted. According to the overall results obtained for the described case conditions, reinforced gypsum panel causes the most adverse environmental impacts, followed by cement and gypsum panels, respectively.

Effects of agro-waste resources on characteristics of Fe/nanocellulose hybrids and their applications as novel Fenton-like catalysts in dye removal from wastewater

Herein, a novel, effective and bio-based Fenton-like catalyst by in situ incorporation of Fe2O3 nanoparticles on the surface of nanocellulose (NCs) was synthesized from sugar beet pulp (SBP) and utilized for efficient removal of three different dyes. Firstly, different NC samples were synthesized by acid hydrolysis of two different biomass (SBP and Q-quinoa husk) at various concentrations of H2SO4. The characterization analyses of samples showed that SBP-based NCs prepared using 60% concentration of H2SO4 (1 h string at 50 °C) showed the highest crystallinity (56.7%), lowest aggregation, highest surface negative charge (−38.5 mV), and largest surface area (13.9 m2/g) compared to the Q-based NCs. Both SBP and Q-based nanocatalyst utilized for degradation of dyes (methylene blue (MB), crystal violet (CV), and congo red (CR)), and SBP-based sample (Fe/NC-S3) displayed the best results in dye removal due to its larger specific surface area (39.8 vs. 9.2 m2/g), and higher content of magnetic nanoparticles (6.7 vs. 3.7 at% of Fe) than Q-based catalyst. At optimum conditions, Fe/NC-S3 nano-catalyst (2 g/L), in the presence of H2O2 (30 mM) removed MB, CV, and CR dyes (30 mg/L), in 30 min, at neutral pH, with 98%, 96%, and 62% removal efficiencies, respectively. Kinetic studies revealed that pseudo-first-order model was appropriate model to explain the decolorization of dyes at these conditions, and the rate constants were 0.0217, 0.018, and 0.0113 min−1 for the degradation of MB, CV, and CR, respectively. Moreover, raising the temperature from 15 ºC to 35 ºC resulted in enhancement of removal performance of nano-catalyst for all dyes. Fe/NC-S3 nano-catalyst showed proper reusability (just around 20% decrease for removal of all three dyes after ten consecutive reuse runs). Treatment of real water effluent (collected from a textile factory) containing mixture of all three dyes by Fe/NC-S3 and H2O2 approved the practical application of nano-catalyst in dye removal from complex matrixes even after nine reusing cycles. The results confirmed that SBP biomass could effectively turn to valuable NC nanocarriers for synthesis of advanced and innovative catalysts with proficient catalytic activity, stability, and recyclability.

The Acoustic Performance of Natural Composites in Reducing Stress Levels: Textile Industry

The porous characteristics of recycled natural fibres make them suitable for use as acoustic materials. Straw and water hyacinth fibres are natural materials that can potentially be used as composites in damping devices. This study evaluated the acoustic performance of two types of reinforced composites containing natural fibers (water hyacinth and rice straw) and gypsum adhesives in reducing stress levels in the textile industry. The evaluation was carried out through laboratory tests using impedance tubes and direct testing in a textile factory to reduce the stress level of production machine workers and operators. Rice straw and water hyacinth fibres were thoroughly mixed in proven mass ratios of 10% and 30% with water and gypsum plaster as a binder. The mixture was pressed into a mould at a pressure of 3 MPa before being heated in an oven at 900ºC for 5 hours. Perforations measuring 4 to 8 mm in diameter were then made at equal distances on the panels. Acoustic panel performance tests were carried out with impedance tubes according to ISO 10534-2 standards at sound frequencies ranging from 0 to 6400 Hz. Field tests were also conducted at a textile factory, with each machine unit generating a sound source of 100 to 110 dB. Heart rate data was collected, and noise measurements were carried out before and after the panels were installed in the area around the operating machines. The results showed that the rice straw-gypsum composite with four perforations performed the best, achieving an α coefficient of 1.0 at a frequency of 1500 Hz and an NRC of 0.50, indicating effective noise reduction. The installation of acoustic panels around the noise source in the textile industry reduced noise levels by up to 9.8 dB and was found to affect workers' heart rates, indicating reduced stress levels. The questionnaire results also showed a significant effect on the stress levels of workers. The use of natural fibers in composite materials has the potential to be an eco-friendly and sustainable solution for soundproofing applications. Doi: 10.28991/CEJ-2023-09-06-02 Full Text: PDF

Theoretical Study of The Use of Lfscs in Terms of Energy for Textile Factories: The Example of Saint Louis in Senegal

Senegal has a high potential for solar energy but mainly depends on fossil energy resources. Industries, particularly the textile sector, could benefit from the use of alternative energy sources to reduce costs and improve the environmental footprint. This study focuses on the use of linear Fresnel solar collectors (LFSC) coupled with an Organic Rankine Cycle (ORC) system to produce energy in textile mills, particularly in Saint Louis. The objective was to size a Fresnel solar array and evaluate its energy production for two different periods: the sunniest month (April) and the least sunny month (August). The findings demonstrate the substantial solar potential of the region, with significant sunshine throughout the year. The maximum direct solar radiation recorded on August 15 and April 25 was 898 W/m2 and 945 W/m2, respectively, at noon. The maximum energy production for one row in August is 24.4 kWh, and in April, it reaches 25.7 kWh. It is noted that, for the use of the Fresnel linear system, the number of rows will depend on the energy needs of the textile factory.

A Feasibility Study on Textile Sludge as a Raw Material for Sintering Lightweight Aggregates and Its Application in Concrete

This study aimed to investigate the feasibility of textile sludge as a raw material for sintering lightweight aggregates (LWAs) and its application in concrete. Three samples of different components were taken from the textile sludge, which came from different textile factories in Taiwan. The analysis of the chemical composition of the sludge shows that the total content of SiO2, Al2O3, and Fe2O3 in the textile sludge was far lower than the recommended value in the literature, and that glassy melt could not be produced and sintered into LWAs alone. Therefore, the water purification sludge obtained from a water purification plant owned by the Taiwan Water Supply Company was used as the main raw material, and the textile sludge was used as the auxiliary raw material in addition amounts of 7.5%, 15.0%, and 22.5%. The test results showed that the LWAs sintered by adding textile sludge to water purification sludge could reach the particle density that is generally required for LWAs (between 0.2 and 1.8 g/cm3). The 14-day compressive strength of the lightweight aggregate concrete made from textile-sludge-based LWAs was between 20 and 25 MPa. This means that textile-sludge-based LWAs can be used in secondary structural concrete.

Analysis of verification results of protective effects of hearing protectors in different industries

Objective: To get insight into the current practice of noise reduction effect of workers as they wore hearing protectors in different domestic enterprises and the possible affected factors. Methods: From October 2020 to April 2021, using a random sampling method, 1197 workers exposed to noise in petrochemical factories, textile factories, and parts manufacturing factories were selected as the study subjects. The noise reduction effect of hearing protectors worn by workers in daily use was tested using a hearing protector suitability testing system. The personal sound attenuation level (PAR) was compared among workers in three enterprises, Targeted intervention and repetitive testing were conducted for workers who did not meet the noise reduction effect required by the enterprise, and the changes in PAR of workers before and after the intervention were compared. The comparison of baseline PARs between two or more groups was performed using the Mann Whitney test, the comparison of baseline PARs with post intervention PARs was performed using the Wilcoxon signed rank sum test, and the comparison of qualitative data between two or more groups was performed using the Chi square test. Results: The median baseline PAR for all workers was 15 dB. Men, age<30 years old, education level at or above college level, working experience of 5 to 15 years, and those who used hearing protectors for 5 to 15 years had higher PARs, with statistically significant differences (P<0.05). The median difference in baseline PAR among workers from three enterprises was statistically significant (H=175.06, P<0.01). The median PAR of subjects who did not pass the baseline increased from 3 dB to 21 dB after intervention (Z=-27.92, P<0.01) . Conclusion: Some workers wearing hearing protectors do not meet the required PAR, and low PARs may be related to incorrect wearing methods and incorrect selection of hearing protectors. As a tool for testing, training, and assisting in selection, the hearing protector suitability testing system is of great significance for worker hearing protection.

Where Things Go

In the mid-60s, in the small Belgian town of Verviers, most of the textile factories that had contributed to the town’s prosperity closed down. On witnessing the end of an epoch, the town council decided to put together a collection of old textile machines that is now stored in an old industrial shed. The film portrays a group of retired men spending their free time repairing the machines and creating a Lieu de mémoire where they relive their former professional activity.&#x0D; Imitating their passion, I created my own collection of former industrial objects. By buying old weaving shuttles from flea market sellers that wanted to get rid of them, I sought to give a sense of the fragile collective memory of the city inhabitants where memories compete with oblivion.&#x0D; Like the warp and weft of a fabric, these two filmic materials weave together to form the film Where Things Go—a film that questions the attachment we have to things, to memory, and to the past.

Relevance of Ecolabel Scheme on Textile/Textile Product to Support Sustainable Consumption and Production Pattern in Indonesia

&lt;p&gt;Everyone has the right to have access to sufficient, safe and physically accessible water for personal and domestic use. River is one of the water resources, which is highly necessary for the people who live in close contact with it. In the past few years there have been several law cases of water pollution in some Indonesian rivers caused by textile factories, who had been releasing untreated wastewater into the river. The wastewater had become harmful to humans and river life mostly due to toxic synthetic dyes chemicals used in textile production. This research aims to provide the reasons to apply ecolabel scheme on the textile/textile products in regards to sustainable development especially the Sustainable Development Goal (SDG) number 12: Sustainable Consumption and Production, which requires that people urgently reduce ecological footprint by changing the way they produce and consume goods and resources. This is a qualitative juridical normative study with statute approach, historical approach and philosophical approach, conducted by using secondary data and are collected by using the method of literature review. According to this research, ecolabel scheme on textile/textile product is relevant to support sustainable consumption and production pattern in Indonesia because it is a way to protect and preserve the environment especially river water in accordance with the international environmental laws regarding sustainable development, Indonesian legislation regarding sustainable development, and Dignified Justice (a justice concept based on Pancasila, the Five Principles of Indonesian State).&lt;/p&gt;

Sorghum-grown fungal biocatalysts for synthetic dye degradation

The synthetic dye discharge is responsible for nearly one-fifth of the total water pollution from textile industry, which poses both environmental and public health risks. Herein, a solid substrate inoculated with fungi is proposed as an effective and environmentally friendly approach for catalyzing organic dye degradation. Pleurotus ostreatus was inoculated onto commercially available solid substrates such as sorghum, bran, and husk. Among these, P. ostreatus grown on sorghum (PO-SORG) produced the highest enzyme activity and was further tested for its dye biodegradation ability. Four dye compounds, Reactive Blue 19 (RB-19), Indigo Carmine, Acid Orange 7, and Acid Red 1 were degraded by PO-SORG with removal efficiencies of 93%, 95%, 95%, and 78%, respectively. Under more industrially relevant conditions, PO-SORG successfully degraded dyes in synthetic wastewater and in samples collected from a local textile factory, which reveals its potential for practical usage. Various biotransformation intermediates and end-products were identified for each dye. PO-SORG exhibited high stability even under relatively extreme temperatures and pH conditions. Over 85% removal of RB-19 was achieved after three consecutive batch cycles, demonstrating reusability of this approach. Altogether, PO-SORG demonstrated outstanding reusability and sustainability and offers considerable potential for treating wastewater streams containing synthetic organic dyes.

An Overview of the Level of Temporary Hearing Loss or Temporary Threshold Shifts (Temporary Deafness) in Workers of PT. X Undergoing a Standard Threshold Shift (STS)

Noise is unwanted sound or sound that interferes with hearing originating from work tools or production process equipment at a certain level that can cause hearing loss, can come from the textile factory industry, milling factory, iron and steel industry and most commonly in places aircraft maintenance.

Kara Walker: A Black Hole is Everything a Star Longs to Be

Following exhibits in Basel and Frankfurt, Kara Walker’s show A Black Hole is Everything a Star Longs to Be: Drawings 1992–2020 is on display in the De Pont Museum for Contemporary Art in Tilburg, The Netherlands. New works on paper alongside a selection from Walker’s private archives compose a treasure trove of well over 600 drawings, experimental writings, personal notes, dream narratives, sheets of textual and visual play, found objects, and scrolls. Incontrovertibly finished pieces appear side by side with try-outs, gestures, studies, and sketches. Occupying the halls of a former textile factory, they proclaim the ongoing process of making, a lot more making, and then trajectories of other kinds of making: new forms, new directions. The viewer soaks up the existential inquisitiveness permeating the artist’s encounter with language and the world: with concrete political developments and incidents in the news but also with the colonialist tools, identity constructions, and racial and gender elisions honed by centuries of Western art. A spirit of playful investigation and rambunctious humour hails from many works. Lightness is seldom absent. It is an aspect of the works’ depth of curiosity. Gravity and levity fuel each other in engagement with ferociously difficult subjects, carried by form and language (Figure 1). A compellingly anti-heroic notion of cultural agency emerges from this subjective richness, which veils neither pleasure nor racial and sexual atrocity. One expects this affective intensification and conceptual rigour from Walker, but it is a stunning accomplishment when it flows forth from a massive turn to the artist’s archive.

The occupational distribution of foundling apprentices during the English Industrial Revolution

ABSTRACT This article presents a new analysis of the distribution of apprenticeships brokered by the London Foundling Hospital, England’s pre-eminent charitable foundation in the eighteenth century for orphaned and abandoned children. It explores the similarities and differences between charity apprenticeship and parish apprenticeship systems in supplying pauper children’s labour during the critical first phase of the English Industrial Revolution, within a wider European context. The results of this analysis illustrate that foundling children were set to work in agriculture, mainly in northern England, and in a variety of small manufacturing and retailing industries in the London area. For a short time, foundling girls were sent in batches to work in textile factories in the North and Midlands, but this practice was soon ended over concerns for children’s welfare. The extensive patronage networks of Foundling Hospital Governors and inspectors, the location of provincial branch hospitals set up to cope with the high volume of so-called ‘General Reception’ children, and gendered expectations of the life courses of the labouring poor were the most significant factors in determining where foundling children were sent as apprentices, and how they were employed.

Fabric yarn detection based on improved fast R-CNN model

With the rapid development of modern computer technology, and gradually combined with the textile industry, the application of modern computer technology in the field of textile is increasingly extensive, which makes textile production gradually move towards the road of automation development. This paper proposes an automatic detection method of simple weave fabric density based on computer image vision. Computer vision and digital image processing technology are used to analyze and identify the simple weave fabric's warp and weft yarn information and calculate the fabric density. To avoid the phenomenon of warp and weft yarn skew, a method of fabric skew correction based on the Radon transform is proposed. The optimal decomposition order of these four fabrics is k = 2, k = 5, and k = 3. The decomposition series is k. It is found that the relative error of both warp and weft density is about 1.00%. Most of the data obtained by the method of correlation coefficient curve to determine the optimal decomposition series are consistent with the results of the energy curve method. The relative error of the density test results of No. 3 fabric, No. 6 fabric, and No. 7 fabric is higher than 10%, and the relative error of No. 3 fabric is the highest, reaching 66%. This shows serious errors in these three fabrics' warp and weft density. To solve the problems of simple weave fabric density detection, the corresponding algorithm is used to solve the problems. Finally, good results are obtained, which verifies the feasibility of this method. It is significant to realize the automatic measurement of fabric density in textile factories.

Impact of Hiring Contractual Workers on Sustainable Supply Chain in Exporting Textile of Pakistan

Textile industry is one of the major sources of revenue generation for Pakistan. For the last two decade this has been the key source of the inflow of foreign exchange through export of garments and textiles goods. Many global retailers and brands like Tesco, JC Penny, Wal-Mart, and Next etc. are sourcing their goods from Pakistan. These Retailers purchase garments and textile on some specific conditions such as cheap merchandising, quality standards and social and environmental compliance. In order to comply with social standards these multinational buyers enforce their vendors to follow the land law and their own code of conduct. The severity of issues varies from violation to violation. For example, nonpayment of overtime violations is taken as serious issues. In contrast, failure to pay legal benefits to labors as EOBI, group insurance and leaves are less threatening. Hiring contractual employment especially on piece rate is one of the core factors that lead to these non-compliances (NCs). A total of 60 unpublished social compliance onsite audit reports of textile and garment factories working with foreign buyers in Pakistan were analyzed. Chai-Square test applied to test the hypothesis. The result reflects that there is an association exists between hiring contractual piece rate workers, employment old age benefit, and group insurance and leaves violation. Current study may be helpful in exploring the major factors that may lead to overtime, employment old age benefit, group insurance and leaves violation. The findings may also help NGOs, government and global buyers to develop policies that provide better control over workers’ rights in developing countries like Pakistan for sustainable business growth.

Developing Sustainable Methods for Softener and Fixing Agent Application in HT Dyeing Machines

Global warming, which is one of the problems brought by the increasing population day by day, and the rapid depletion of water resources have increased the restrictions on water use. Thus, more environmentally friendly and sustainable production processes are developed by producers and consumers. The number of studies carried out to minimize the use of raw materials in textile dyehouses is increasing day by day. The high chemical load, waste water usage rate and energy cost resulting from pretreatment, dyeing and other processes vary according to the processes used in textile factories.&#x0D; Our company aims to support environmentally friendly studies that contribute to the economy in production processes. While producing in the paint shop, energy, water, chemicals, etc. It also aims to use raw material resources sparingly. In this study, the efficiency studies carried out in HT dyeing and finishing processes in the dyehouse of our company were examined. By optimizing the post-processing performed in HT machines after dyeing, softener and fixator chemicals applied in HT machines were carried out by using double pads before drying in stenter machines after trials. Obtained results were compared with old methods. A sustainable new method has been developed without any color, fastness or touch difference between the old system and the new system.&#x0D; With this new process study, our company's water, energy and chemical savings and the company's impact on the environment have been reduced, while time savings have been achieved by shortening the process time. In the test results, there was no problem in washing, color and rubbing fastness efficiency. No change was observed in the touch of the products after the application of the softener step with the impregnation method instead of shrinking. As a result of the study, while the water consumption was reduced by 20%, the process time was also reduced by 19%.

The relationship between iron deficiency anemia with restless leg syndrome and sleep quality in workers working in a textile factory in Iran: a cross-sectional study

BackgroundThe aim of this study is to investigate the relationship between iron deficiency anemia with restless leg syndrome (RLS) and sleep quality in workers working in a textile factory in Iran. This cross-sectional study was conducted on 216 workers working in a textile factory in Iran. In addition to demographic and occupational variables, Pittsburgh Sleep Quality Index (PSQI) and RLS questionnaires were used for the data collection. To investigate iron deficiency anemia, 2 CC of blood was taken from the brachial artery with the help of a 10-CC syringe with a blue or pink tip. Then, relevant data were entered into SPSS26 and analyzed.ResultsThe mean (S. D.) age of the workers was 32.23 (6.14) and 60.6% of them were women. The prevalence of iron deficiency anemia was 21.2 and 69.5% in men and women, respectively. Most of the workers were in moderate condition in terms of RLS severity, and 78.2% had sleep disorders. There was an inverse and significant correlation between age (β= −0.200), work experience (β= −0.160), hemoglobin (β= −0.149), and ferritin (β= −0.186) with global PSQI score (P value<0.05). Also, an inverse and significant correlation was observed between age (β= −0.164), hemoglobin (β= −0.548), and ferritin (β= −0.410) with RLS score (P value<0.05). However, there was a direct and significant correlation between TIBC level and RLS score (β= 0.227) and global PSQI score (β= 0.395) (P value<0.05).ConclusionsIntervention programs to reduce iron deficiency anemia and periodic screening programs to identify sleep disorders and RLS in textile factory workers seem necessary.

Mobile financial services and household welfare in a developing economy: boon and bane

PurposeThis study aims to investigate whether the introduction of innovative financial products increases welfare for low-income households working in the manufacturing sector. Specifically, the authors measure the impact of mobile financial services (MFSs) on economic opportunities and wellbeing of garment factory workers in Bangladesh.Design/methodology/approachThe study is based on Amartya Sen’s Capabilities Approach. Close to 400 textile factory workers were interviewed about their experience using Bangladesh’s most popular MFS, and how their household welfare has changed over time. Results were tabulated and analyzed with simple statistical tools.FindingsWhile there remains an abundance of friction in the system, financial innovation still assisted low-income households in savings, and expedited and secured their fund transfers. The introduction of the new technology, especially when it is made mandatory, seems to have disempowered married women by reducing their financial independence from their husbands.Originality/valueThis study should help policy makers and international bodies in their efforts to design and support the inclusive growth of mobile financial technology.

Industrial Water Demand and Wastewater Generation: Challenges for Bangladesh’s Water Industry

Bangladesh has experienced massive industrial growth in the past century. With the impressive industrial development, the country struggles to meet the demand for water and manage the wastewater generated. This paper critically analyzes Bangladesh’s three significant industrial wastewaters: textile, tannery, and landfill leachate. The textile and leather industries are major freshwater consumers and wastewater generators in Bangladesh. Most textile factories across Bangladesh operate without effluent treatment plants, causing severe water pollution. Unlike textile plants, most tanneries are located in Savar, Dhaka. Savar’s newly constructed central effluent treatment plant has serious design flaws and cannot meet discharge standards. Bangladesh has only three sanitary landfills for municipal solid waste disposal. With inadequate leachate collection and treatment facilities, the landfills have become point sources of surface water and groundwater pollution. The pollution of water resources is devastating as Bangladesh depends on surface water for irrigation and groundwater for drinking. Although Bangladesh has mandated laws and regulations for water pollution control, the lack of implementation is a significant problem. To get a better handle on industrial water demand and wastewater treatment, the Bangladesh government and the Department of Environment should work together to implement stricter laws and regulations and emphasize technical workforce development and stakeholder training.

The relationship between noise-induced hearing loss and cognitive function

Introduction NIHL may affect some domains of cognitive function. This study was conducted to assess the relationship between NIHL and working memory, attention and response time. Materials and methods This was a cross-sectional study on 154 textile workers with exposure to noise higher than 85dBA in a textile factory. The participants were divided into two groups: with and without NIHL and some domains of cognitive function were compared between two groups. Wechsler working memory test and Stroop color-word test were used to measure working memory, selective attention and response time. Data were analyzed by SPSS (ver. 24) using student’s T test, and multiple linear regression model. Results Totally, 154 workers entered the study (77 with NIHL and 77 without NIHL). All participants were males. Working memory score and response time were higher and interference score was lower in NIHL group, although only the difference in working memory was significant. Due to the significant difference of age and work history between case and control groups, cognitive parameters were compared between two groups after adjusting for these two variables, but the significance was not changed. Conclusion This study showed that noised-exposed middle-aged males with NIHL had probably a lower working memory span than their counterparts without NIHL.

Development of Food-Based Recommendation and Nutrient-Dense Meal for Female Shift Workers in West Java, Indonesia

Introduction. Some manufacturing industries employ not only male workers but also female workers, who are required to undergo shift work. Given the altered eating habits as well as metabolic and endocrine profiles of shift workers, this will affect their nutritional needs. Considering that anemia that occurs in female workers is primarily nutritional anemia, this becomes a challenge in the field of occupational nutrition, especially in terms of preparing food for female workers in accordance with their nutritional needs. The aim of the study is to develop a set of FBR for female shift workers using the Linear Programming (LP) approach. Methods. Dietary data were collected in a cross-sectional survey of female shift workers (n=106) working at a textile factory in Sumedang District, West Java, Indonesia, and a market survey in two local markets. Optifood software was used for LP analysis particularly to identify problem nutrients, and nutrient-dense foods, and compare alternative FBRs. The nutrient-dense menu was developed using the identified nutrient-dense foods. Results. The problem nutrients were iron (absolute) and calcium (partial), and the remaining nutrients were still dietary inadequate. The nutrient-dense menu including iron-rich and folate-rich foods can fulfill the nutrient gap for iron from the final FBR (15% RNI of the 7% RNI). Conclusion. The inclusion of a nutrient-dense menu for the female factory workers helped to meet the nutrient gap for iron which is the absolute problem nutrient in the optimized FBR. The promotion of optimized FBR and the provision of a nutrient-dense menu should be part of the occupational nutrition program.
