ABSTRACT

PurposeThe purpose of this paper is to determine the amount of different kinds of solid wastes produced, segregated, collected, stored, transported and disposed off by the different industries/business in Kuwait.Design/methodology/approachAvailable industry information along with the use of monitoring data from a waste management system were used to analyze the generation, type and composition of industrial waste. Industrial activities were classified as follows: crude oil and chemical products industry; food and beverage industry, textiles and leather industry, wood industry, paper and printing industry, non‐metallic mineral products; metal industry and other industries. The wastes generated were classified according to their composition.FindingsKuwait has more than 5,000 industries and as a result more than 47,169 tons of industrial wastes are produced every year in Kuwait. It was observed that paper and cardboard, plastic, wood, and metals were the most common types of waste, mainly generated from packaging (45 percent of the total volume), as well as material used in containers and for wrapping products.Practical implicationsIn the management of these industrial solid wastes, it was observed in most cases they were disposed of by dumping, and very rarely did businesses resort to reuse, recycling or valorization.Originality/valueThe paper systematically assesses the obstacles in the existing industrial solid waste management system in the different industries and businesses in Kuwait. In addition, it examines the legislation set by the Environmental Protection Authority (EPA) in Kuwait. Subsequently, recommendations and improvements are suggested.

There are a variety of techniques for estimating the parameters x and K of the Muskingum method of flood routing. One common difficulty in all the approaches is that different storm sequences along the same river reach would typically yield different parameter estimates. The a statistical analysis of these parameters also shows that they are highly variable. As a result achieving of a high level accuracy may not be the principle issue in describing x and K. This paper presents two approximate methods for estimating these parameters rather easily. The first method requires the computation of the slopes of the inflow and outflow hydrographs at their point of intersection, and the computation of the maximum storage within the reach. The second method requires the computation of the inflow and outflow hydrographs at two specific points. Three case studies investigated show that the first method gives estimates for the Muskingum parameters comparable to those derived by traditional estimation procedures for hydrographs showing linear characteristics.

Purpose -The purpose of this paper is to determine the amount of different kinds of solid wastes produced, segregated, collected, stored, transported and disposed off in the governmental hospitals of Kuwait. Design/methodology/approach -The research in this paper shows that all governmental hospitals were assessed in a period of six months (
