Intensive manual labor enterprises in the developed world face challenges competing with products imported from countries where manufacturing costs are low. This reduces the volume of domestic production and leads to rapid loss of knowledge and experience in production processes. This study focuses on the Israeli footwear industry as a case study. Qualitative methodologies were applied, including in-depth interviews and field observations. A literature review on previous research, and contemporary trends was conducted. The field research examines challenges along the value chain in small factories. It finds that mass production paradigms impose a decentralized process between designers and manufacturers and therefore do not leverage local potential into a sustainable competitive advantage for small factories. The proposed solution is a digital and technological platform for small manufacturing plants. The platform mediates and designs the connections between production, technology, and design and enables the creation of a joint R&D system.

Overall Resistance

Foundries in manufacturing plants are characterized by hazardous working conditions. The paper makes an assessment of industrial health hazards, identifies groups of diseases dominant among the examined individuals. It is clear that gastrointestinal diseases make the largest percentage. The effect of destabilizing industrial factors that lead to the intestinal biome restructuring, help reduce the dominant microorganism’s group and increase opportunistic flora has been determined. The severity of this indicator correlates with professional working experience. Along with the fecal matter bacterial flora of the examined people, the protozoa that belong to the parasitic group (blastocysts, lamblia, amoeba) were identified, and Blastocystis spp. has the largest proportion. The biological properties of blastocysts were studied exemplified by anticarnosine activity (AcrA), which allows them to colonize the intestinal mucous membranes and helps displace obligate symbiotes against the decrease in the overall resistance of the macroorganism. The data obtained make it possible to forecast human health state under the conditions of anthropogenic-disturbed territories and plan measures to improve and protect workers’ health.

Nine strains of yeasts capable of decomposing oil were isolated in order to directly treat wastewater from oil manufacturing plants with no pretreatment. The oil decomposing ability of these yeast strains was evaluated in terms of lipase activity and β-oxidation activity. Since the mixture of the isolated yeasts was superior to any single strain in the oil removal rate, a pilot plant utilizing the mixed strains was operated at the soybean oil factory. Following a one year pilot plant operation, it was found that 10,000 mgℓ−1 of hexane extracts in the raw wastewater could be reduced by yeast treatment to a concentration of about 100 mgℓ−1. This concentration was further treated by the activated sludge process to 2 mgℓ−1. The dominant yeasts in the pilot plant were found to form mycelial or pseudomycelial pellets and have low fermenting ability.
