Abstract:

This paper evaluates the effectiveness of waste management systems in Maramba Tea Factory in Kiambu County, Kenya. Performance of the already existing systems is therefore critical in sustaining our environment. Tea processing generates different types of wastes. A waste management system design should at least begin from a clear characterization of these wastes, the quantities and qualities of the wastes and identification of sources. This study attempted to bring these challenges to the fore. It evaluated the waste management systems for Maramba Tea factory in Kiambu County, Kenya. Primary d

Policy on the management of the living environment in Indonesia changed with the promulgation of Act No. 32 in 2009 on the protection and management of the environment. While Act No. 18 in 2008 specifies the policy on waste and trash management. In accordance with the concept of environmental ethics the application of environmental ethics in North Sumatra is vital to develop good waste management (Keraf, 2012). The concept of environmental ethics reviews human, nature and environmental relationship between people with the natural environment (Keraf, 2004). The purposes of this writing are: (1)

Abstract:

Food waste is a critical issue affecting the world, and more research is needed to find ways to reduce it. Much of the existing research has examined supply chain inefficiencies and plate waste in restaurants and homes, while few researchers have studied the food waste which occurs in factory cafeterias. As many factories are in Asia, examining factory cafeteria food waste behavior in an Asian context is a good starting point. With this in mind, the authors research drivers that influence Taiwanese factory workers’ behavioral intentions toward food waste reduction. To do so, a conceptual frame

Abstract:

Waste is a by-product resulting from a process. Waste if disposed of freely without prior processing can harm the surrounding environment. Proper waste management makes waste more friendly to the environment. There are even several categories of waste that can be reused. A sugar factory is a company that processes sugar cane into crystal sugar that can be used for cooking. At the sugar factory, there are problems that occur, namely the absence of waste processing that is produced as a by-product of the production process. Therefore, in this research, the design of by-products of the sugar prod

Abstract:

Cluster analysis is a method for grouping objects that have the same characteristics. One of the methods in cluster analysis used to group data is the K-Medoids method. In this study the K-Medoids method was applied to classify provinces in Indonesia based on environmental pollution. The variables used are: the number of sub-districts/villages that experience water pollution from factory waste, the number of sub-districts/villages that experience water pollution from household waste, the number of sub-districts/villages that experience soil pollution from factory waste, the number of sub-distr

Abstract:

It is a well-known fact that the use of agricultural wastes in cementitious composites by turning them into ash provides both ecological and economic benefits. Tea factories in Türkiye are located in the Eastern Black Sea region. Tea waste generated in factories locally causes environmental problems. This study focuses on the usability of the wastes left over from the products processed in the tea factory. Tea waste from Artvin, Türkiye was turned into ash at 850 °C. Physical, chemical, mineralogical, thermogravimetric and morphological properties of tea waste ash were examined. Pozzolanic act

Abstract:

The tofu industry is currently expanding in Indonesia, especially in Purwogondo Village, Kartasura District. In the village, the majority of the population produces tofu. Tofu production is still carried out using traditional and simple technology. This causes the level of efficiency in the use of water and raw materials is still low but the level of waste production is also relatively high. Based on the research that has been done, the human resources involved or the workers in the tofu factory in the village generally have a relatively low level of education, so that not many workers and the

Abstract:

Factory made steel fiber and steel fiber derived from worn tires was used to develop cement concrete, which was subjected to torsional forces. A dedicated stand for torsion tests, allowing for the measurement of force, deflection, and torsion angle, was used. The test results showed that both the factory-made fiber and the waste steel fiber significantly improved torsional properties of the concrete matrix. The test results of specimens made with waste fiber were characterized by slightly worse results compared to factory-made fibers, but there was a significant improvement in torsional proper

One of the home industries located in Martapura, Banjar Regency, is a tofu factory. The raw material for making tofu is soybean seeds which are processed so that the main product is tofu. In addition to producing tofu, the factory also produces by-products in the form of liquid waste and solid waste. So far, liquid waste is not used, but solid waste is used as animal feed. For this reason, in the application of science and technology, skills are given in the form of training to utilize liquid waste from the tofu industry into a new product, namely Nata de Soya.

Abstract:

To prevent the formation of salt from fission products of high-level radioactive liquid wastes (HLWs), a certain amount of acid is added to maintain the acidity of liquid waste. This study analyzes the accidents associated with the addition of acids in a factory by using the hazard and operability analysis (HAZOP), while elucidating the corresponding defects and risks of this approach. By improving the design of the system, the possibility of an accident is significantly reduced. This study can provide guidance for adding acids to treat other high-level waste liquids.

Abstract:

There are many environmental problems caused by factory waste. Sugar factory waste, in the form of bagasse ash, and PLTU factory waste, in the form of fly ash, are currently in the spotlight of science studies. This study used waste bagasse and fly ash to substitute Portland cement as the main ingredients for mortar. Baggash and fly ash waste were collected, processed, and then used to replace cement by up to 40% to determine to what extent they could be used in brick masonry work, wall plastering, and masonry paste. Experimental tests were carried out on mortar cube samples measuring 5×5×5 cm

The basic ingredient in making tofu is soybeans which have high nutritional value and can be a healthy protein alternative for the community. Tofu is made from coagulated soybean seed sediment, so that the processing produces water which becomes waste in the tofu-making industry. In increasing production it is necessary to have attention to environmental performance. The aspect of environmental performance is in the form of liquid waste resulting from a large number of tofu production processes. The purpose of t

Abstract:

Tea processing is an energy-intensive process. However, high agricultural productivity and subsequently the growth of the green revolution have been made possible only by a large amount of energy inputs, especially those from fossil fuels, wood fuels, and electricity. With recent price rise and scarcity of these fuels there has been a trend towards use of alternative energy sources such as waste (agricultural waste) to energy that could solve both energy and environment issues. Moreover, these energy resources have not been able to provide an economically viable solution for agricultural appli
