AbstractReuse of materials in ancient Egypt is neither a new nor novel concept. The ancient Egyptians reused a variety of materials and certainly any resource that had spiritual, ideological, or economic value that was available to them. Yet, reuse of certain raw materials has not been thoroughly examined, notably timber. This manuscript explores the modes, preferences and implications of wood use, specifically reuse, in Egypt’s Pharaonic Period, using ship timber as the illustrative example. This synthesis suggests specific preferences for commodity consumption and conservation existed, revealing cultural and behavioral trends.

Alga is a marine resource of potential to fisheries and marine sector. It has an important economic value to promote the economy in Indonesia. Nowdays, algae have been used as a relatively high value fisheries commodity since it has been used for food, industrial, pharmaceutical and cosmetic raw materials. This important potential needs to be supported with understanding of its biology and ecology, so that its utilization could increase the livelihood of the coastal villagers. This study was aimed at inventorying and identifying the members of genus Caulerpa found in North Minahasa Regency waters and studying some biological and ecological aspects of the algae in the area. Resuls showed that there were 7 species recorded, Caulerpa racemosa, C. racemosa var. macrophysa, C. sertularioides, C. taxifolia, C. serrulata,C. lentillifera and C. peltata. Ecologically, the environmental parameters, such as water temperature, salinity, pH, dissolved oxygen, turbidity, were in tolerable ranges for algal growth. Bottom substrate supported the growth of genus Caulerpa as well© Saat ini alga dijadikan sebagai komoditas hasil perikanan dengan nilai ekonomis yang relatif tinggi karena manfaatnya sebagai bahan makanan serta bahan baku industri, farmasi, dan kosmetik.

Waste management is still defined as limited to collection, transportation and garbage disposal. The follow-up of the meaning is the provision of facilities such as garbage bins, garbage trucks and waste collection land. Waste management has not included waste separation. Segregation of waste can minimize the amount of waste that must be discharged to the final place. Segregation of waste can supply recyclable raw materials and handicrafts made from garbage. The manufacture of handicraft products from garbage is still local and requires socialization and training. It is needed to increase the number of craftsmen and garbage absorption on the crafters. Through careful socialization and training, citizens' awareness of waste management becomes advanced by making handicrafts of economic value from waste materials.

AbstractThe increase in the world population leads to rising demand and consumption of plastic raw materials; only a small percentage of plastics is recovered and recycled, increasing the quantity of waste released into the environment and losing its economic value. The plastics represent a great opportunity in the circular perspective of their reuse and recycling. Research is moving, on the one hand, to implement sustainable systems for plastic waste management and on the other to find new non-fossil-based plastics such as polyhydroxyalkanoates (PHAs). In this review, we focus our attention on Tenebrio molitor (TM) as a valuable solution for plastic biodegradation and biological recovery of new biopolymers (e.g. PHA) from plastic-producing microorganisms, exploiting its highly diversified gut microbiota. TM’s use for plastic pollution management is controversial. However, TM microbiota is recognised as a source of plastic-degrading microorganisms. TM-based plastic degradation is improved by co-feeding with food loss and waste as a dietary energy source, thus valorising these low-value substrates in a circular economy perspective. TM as a bioreactor is a valid alternative to traditional PHA recovery systems with the advantage of obtaining, in addition to highly pure PHA, protein biomass and rearing waste from which to produce fertilisers, chitin/chitosan, biochar and biodiesel. Finally, we describe the critical aspects of these TM-based approaches, mainly related to TM mass production, eventual food safety problems, possible release of microplastics and lack of dedicated legislation.

The economic value of the Abaca banana is on the trunk which contains fiber for valuable textile and paper industry raw materials. The multipurpose fiber and its prospects are quite good, so the abaca plant gets a lot of attention from various community groups both private, state-owned, cooperative and farmers. Propagation through multiplication humps is very low, planting material is easily damaged in transportation, is not durable and requires large space so that transportation costs are high. One alternative to overcome the provision of healthy, large and fast seedlings is to use seedlings from tissue culture. The aim of the study is to get the right thiamin and leaf fertilizer concentrations at the acclimatization stage. The experimental design used was a 2-factor Complete Randomized Design, Thiamin concentration (1 ml / l, 2 ml / l, 3 ml / l) and leaf fertilizer (0.5 ml / l, 1 ml / l, 1.5 ml / l). The data obtained were analyzed for diversity at 5% level and further tests using Duncan Multiple Range Test (DMRT) level of 5%. The results showed no interaction between thiamin and leaf fertilizer, Thiamin 2 ml / l gave the best results on all parameters and 1.5 ml / l leaf fertilizer could increase plant height and the number of leaves of abaca banana plants.Keywords: Thiamin, leaf fertilizer, abaca banana, acclimatization

Geological Phenomenon

In geochemical prospecting for gold a major difficulty is that many values are below the chemical detection limit. Tracers for gold thus play an important role in the evaluation of multivariate geochemical data. In this case study we apply geostatistical methods presented in Wackernagel (1988) to multielement exploration data from a prospect near Limoges, France. The analysis relies upon a metallogenetic model by Bonnemaison and Marcoux (1987, 1990) describing auriferous mineralization in shear zones of the Limousin. The aim of geochemical exploration is to find deposits of raw materials. What is a deposit? It is a geological anomaly which has a significant average content of a given raw material and enough spatial extension to have economic value. The geological body denned by an anomaly is generally buried at a specific depth and may be detectable at the surface through indices. These indices, which we shall call superficial anomalies, are disposed in three manners: at isolated locations, along faults, and as dispersion halos. These two definitions of the word "anomaly" correspond to a vision of the geological phenomenon in its full continuity. Yet in exploration geochemistry only a discrete perception of the phenomenon is possible through samples taken along a regularly meshed grid. A superficial anomaly thus can be apprehended by one or several samples or it can escape the grip of the geochemist when it is located between the nodes of the mesh. A geochemical anomaly, in the strict sense, only exists at the nodes of the sampling grid and we shall distinguish between: a pointwise anomaly defined on a single sample, and a groupwise anomaly defined on several neighboring samples. This distinction is important both upstream, for the geological interpretation of geochemical measurements, and downstream, at the level of geostatistical manipulation of the data. It will condition an exploration strategy on the basis of the data representations used in this case study. A pointwise anomaly, i.e., a high, isolated value of the material being sought, will correspond either to a geological phenomenon of limited extent or to a well hidden deposit.

Uzbekistan is paying great attention to the textile industry as an industry offering a traditional production advantage, coming to the conclusion that it is necessary to establish and implement effective policies. In Uzbekistan as in other developing countries, whereas there are many strategic directions and development strategies to be considered for key industries, investment resources are limited. Therefore, it is necessary to prioritize and to apply limited resources accordingly. Even though research on the textile industry in Uzbekistan is ongoing for a long time, most of the resultant literature concerns only general industrial trends and pertinent investment and advancement strategies. The present study examined sustainable, concrete, and effective development strategy directions for the Uzbekistan textile industry using strengths, weaknesses, opportunities, and threats (SWOT) analytic hierarchy process (AHP) model. The SWOT-AHP model was tested in a case study on Uzbekistan’s textile industry. In the case study, the results were presented in an illustrative way by utilizing the quantitative information achieved by the model. The results indicated that the weakness and opportunity (WO) strategy had the highest importance, and suggested accordingly that priority should be given to that strategy for Uzbekistan’s textile industry development. The results further suggested that the Uzbekistan government should endeavor to upgrade obsolescent technology and solve the problems of high-priced imported raw materials and workers’ low education level, which are weak points of the textile industry of that country. Also, Uzbekistan should gradually shift the industrial structure from raw cotton to finished textile exportation, which offers relatively high added economic value. To achieve this, the Uzbek government needs to promote joint ventures and strategic alliances with foreign companies wishing to enter the textile industry through foreign direct investment (FDI) schemes.

Potential and opportunities for cassava development are still very broad along with development of companies in livestock, processed food, and other industries. Added value of cassava commodities resulting from development of downstream industries (processed products) is far higher than upstream industries (primary products), so that development paradigm in agriculture sector in future should be directed towards product expansion including its waste. This study aims to examine the economic value of cassava as a future crop from direct as well as by-products and their development strategies. Data was collected from small-scale tapioca flour farmers, ranchers and entrepreneurs. SWOT analysis was used to determine relevant development strategies. Analysis shows that cassava has an potential, especially as a raw material for food and feed industry. In short term, developing cassava strategy as an industrial raw material is to use new technologies i.e. varieties and cultivation techniques for planting arrangements. Cassava potential economic value is relatively high in terms of farming aspects, food raw materials, feed and industry. This potential, apart from main product, is also by-product that has been neglected at 29.7% of cassava main value. By-products potensial has not been used optimally and a bioeconomic value of biomass that can support integrated agriculture in the future.
