Introduction: Surfactant or surface active agents are slightly soluble in water and cause foaming in waste treatment plants and also in the surface waters into which the waste effluent is discharged. During aeration of wastewater, these compounds collect on the surface of the water bubbles and create some problems in waste treatment. Methods: In this study, surfactant, turbidity and COD in the...
Reuse of agricultural wastes and industrial by-products for building materials has been gaining popularity in the recent years. Agricultural waste material; namely rice husk ash (RHA), and industrial by-product; namely expanded polystyrene beads (EPS) are discarded in large amounts globally, causing increased environmental problems. Therefore, this paper introduces innovative efforts of the com...
CONTEXT Industrial waste (which is composed of various toxic chemicals), changes to the disposal process, and addition of chemicals should all be monitored and controlled carefully in the industrial waste industry to reduce the health hazard to workers. CASE PRESENTATION Five workers in an industrial waste plant developed acute toxic hepatitis, one of whom died after 3 months due to fulminant...
accumulation of unmanaged industrial solid waste, especially in developing countries has resulted in an increased environmental concern. in view of utilization of industrial solid waste the recycled paper mill waste (rpmw) – cement composite bricks were designed and developed. in order to investigate the environmental performance of sustainable construction materials two small scale model house...
introduction: countries around the world are looking for an appropriate, stable, and affordable replacement for the natural energies. therefore, the waste is considered as an available resource to produce energy, which by controlling, its effects on the environment could be minimized. methods: to conduct this review article, all the scientific data related to the topic were gathered from scient...
Waste sorts were conducted during each of the four quarters (or seasons) of 1996 at the City of Columbia Sanitary Landfill. A detailed physical sampling protocol was outlined. Weight fractions of 32 waste components were quantified from all geographic areas that contribute to the Columbia Sanitary Landfill using a two-way stratification method, which accounted for variations in geographical reg...
Several proprietary industrial symbiosis software tools have been developed, however, without long term financial commitments these endeavors fall short of creating generalizable and sustainable tools. The recent development of virtual globes such as Google Earth (GE), an information service that provides imagery and three dimensional data depicting the entire physical earth, provides an opport...
Controlled low-strength material (CLSM) is slurry made by mixing sand, cement, ash, and water. It is primarily used as a replacement for soil and structural fillings. This paper presents the findings of a preliminary investigation carried out on the performance of industrial waste incineration bottom ash as CLSM. CLSM mixes were designed using industrial waste incineration bottom ash, and cemen...
Dyes are one of prevalent types of chemicals used by human being today. Dyes are organic compounds which have complex aromatic molecular structure that make them toxic and harmful. When these dyes introduced with water due to textile dyeing and printing industrial waste water may cause problems to all living organism. In these dyes highly toxic metals are used as mordents so the removal of thes...
Industrial Symbiosis (IS) is a sub discipline of Industrial Ecology that aims to bring together companies from different sectors to share resources, namely energy, materials, water (Chertow, 2004)(Jacobsen, 2006). The main goal of IS is to improve resource efficiency and lead to environmental benefits to participants. Benefits are generated by the reduced intake of virgin materials, reduced amo...
