Abstract:

In this study, an experimental bio-grease formulation composed of soybean and cottonseed oils (SBO &CSO) as base oil, lithium hydroxide thickener, and sugar cane filter cake wax (SCW) as an additive was presented. Properties such as viscosity, penetration, drop point, wear, and coefficient of friction (COF) for the formulated samples of bio-grease, were evaluated using standard methods, and the results were compared to the mineral grease. A mixture composition involving the lowest levels of relevant fatty acids in the base oils showed a good structure in the development of film formation a

Abstract:

One commonly used lubricant in rolling bearings is grease, which consists of base oil, thickener and small amounts of additives. Commercial greases are mostly produced from petrochemical base oil and thickener. Recently, the development of base oils from renewable resources have been significantly focused on in the lubricant industry. However, to produce an entirely bio-based grease, the thickener must also be produced from renewable materials. Therefore, this work presents the design and evaluation of three different bio-based polymer thickener systems. Tribological tests are performed to cha

Abstract The dominance of plastics in the packaging market is due to their low weight and thickness, which save transportation costs. However, their non-biodegradability poses a significant threat to the environment. Paper, on the other hand, is considered as a safer alternative due to its natural composition and biodegradability. The porous structure of paper limits its application in packaging, and its poor water resistance further restricts its use in humid environments.

Pada awal pengembangan Perumahan Citra Gran mendesain clusternya dengan fitur laguna. Setelah beberapa tahun beroperasi, kondisi air dari laguna tidak tercapai pada level rencana. Salah satu upaya dari estate management, adalah dengan mengisi laguna dengan air sungai yang diangkut dengan mobil tangki. Namun hal ini menimbulkan biaya mahal. Untuk mengatasi masalah tersebut, maka perlu dibuat rencana desain intake air limbah rumah tangga dengan sistem pengolahan bio teknologi. Pengolahan bio teknologi yaitu mengumpulkan air limbah dari rumah warga, kemudian dilakukan pemisahan antara air dan lem

Abstract:

Poultry slaughterhouse wastewater (PSW) is laden with fats, oil, and grease (FOG), as well as proteins. As such, PSW promotes the proliferation of filamentous organisms, which cause foam formation. In this study, the production of biological defoamers (biodefoamers) uses a consortium with antagonistic properties, i.e., 1.39 L of wastewater/mL defoamers, as reported in our previous study, toward foam formers and their application in the treatment of PSW using a bench-scale activated sludge (AS)-supported treatment system consisting of an aeration and clarification tank. The foam produced was sl

Biochemical products have been widely used for treatment of various types of wastewater. The treatment processes with the addition of biochemical products are quite attractive because of their simplicity, minimal use of equipment, they are environmentally friendly and are suitable for the removal of organic pollutants. The purpose of these products is to enhance the activities of beneficial microbes in order to improve treatment performance. This study was carried out to determine the potential of applying biochemical products in assisting and improving the performance of sewage treatment plan

The separation of oily wastewater is one of the main processes in the water treatment field. A biological approach that can replace the use of chemical coagulants hazardous to human health is an efficient solution in treating oily wastewater. However, bio- coagulants have a time limit that can affect their effectiveness in treating oily wastewater. Thus, this paper presents research for the aging effect of bio-coagulant for treating oily wastewater. In this study, G-Treat was used as the bio-coagulant, which was produced from chitosan powder, acetic acid, and deionized water. The experimental

Abstract:

The treatment of poultry slaughterhouse wastewater (PSW) with an Expanded Granular Sludge-Bed Bioreactor (EGSB) is hindered by the washout of activated sludge, and difficulties associated with the operation of the three-phase separator and the determination of the optimum up-flow velocity for sludge-bed fluidization. This results in a poor reactor functionality, and thus a poor performance due to pollutants such as fats, oil and grease (FOG) in the PSW being treated. Hydrolyzing the FOG content with a bio-delipidation, enzyme-based agent in a pre-treatment unit would significantly improve the

Abstract Horeca Food Waste is waste from the hotel, restaurant and catering sectors. The hotel industry generates 0.8-1.2 kg of food waste per guest. A bioconversion process can be used as a technique for treating food waste. The oil content of BSFL constitutes 35-45% of their whole weight. Research must be conducted on the bioconversion of horeca food waste (from hotels, restaurants, and catering) into oil derived from black soldier fly larvae. The study utilised horeca waste bioconversion to investigate environmental parameters, analyse the bioconversion properties of food waste, extract BSF

To reduce plastic pollution, it is of interest to develop biodegradable molded fiber products from recovered cellulose-containing residues as an alternative to single-use plastics. Primary questions to be addressed include how to compound molded fiber products from the recycling of paper or cardboard and agricultural residual wastes via combined vacuum thermo-forming and post-drying or synergistic cold and hot press approaches. In addition, consumers will have high expectations regarding barriers for moisture and grease. It is proposed here to produce uniform barrier molded fiber products via

Sunflower oilcake flour (SFOC) resulting from the cold extraction of oil is a rich source of valuable bio-components that stimulated the development of novel, biodegradable and edible films. The films were prepared by incorporating different concentration of sunflower oilcakes (0.1–0.5 g). The obtained films were characterized in terms of physical, water-affinity, antimicrobial and morphological properties. The edible-film properties were affected significantly by the presence and the level of SFOC added. The water vapor permeability and water vapor transmission rate improved with the amount o

In wastewater from small communities, institutions, hotels, camps and tourist areas the major pollutants such as organic matter, oil and grease and organic nitrogen are mainly in particulate form, while the soluble fractions of organics and nitrogen are low. This is due to the short residence times in the sewerage systems preventing decomposition and lysis. Such wastewaters are also characterized by high variations in pollution load, mostly in the particulate fraction. Small plants, treating wastewater for discharge to lakes or rivers, have to remove organic pollutants and nutrients, mainly ph
