  • Designed for generations, water & wastes digest

    Nearly 25 years ago, the consulting engineering firm Banner & Associate, Inc. designed an efficient wastewater treatment facility for the city of Madison, S.D., that featured process control, flexibility and treatment efficiency while minimizing operating and maintenance costs. Key to the system was the aspirator aeration system that supplied reliable oxygenation and mixing to the oxidation ...

  • Waste quantification models for estimation of construction and demolition waste generation: a review

    Quantification is crucial for construction and demolition waste management. Accurate estimation can be satisfied by developing waste quantification model that is applicable for regional or nation–wide C&D waste generation. This paper presents a review on quantification models for C&D waste from literatures and how they correlate. Most studies combine the empirical waste assessment data or waste ...

  • Urban Food Waste generation: challenges and opportunities

    Greater economic activity and a wider economic gap between rural and urban areas is leading to accelerated urbanisation and the generation of 35% more Urban Food Waste (UFW) from 2007 to 2025. Besides landfilling, this paper examines the advantages of introducing onsite composting and anaerobic digestion for the environmental recycling of UFW and the lowering of handling cost. For Asia and ...

  • Biomedical Waste Generation in Puducherry Government General Hospital and Its Management Implications

    In India, not much attention has been paid to the management of biomedical waste (BMW). The present paper describes the collection and disposal of BMW in the Government General Hospital (GH) of Puducherry, India. The authors document (a) the lack of segregation between infectious and noninfectious BMW as well as a failure to implement the prescribed rules for proper management of BMW; (b) ...

  • Is it better to burn or bury waste for clean electricity generation?

    The use of municipal solid waste (MSW) to generate electricity through landfill-gas-to-energy (LFGTE) and waste-to-energy (WTE)projectsrepresentsroughly14%ofU.S.nonhydrorenewable electricity generation. Although various aspects of LFGTE and WTE have been analyzed in the literature, this paper is the first to present a comprehensive set of life-cycle emission factors per unit of electricity ...

  • Analysis of the generation of household solid wastes, household hazardous wastes and sustainable alternative handling

    In the southern part of Mexico City, household solid wastes (HSWs) were examined qualitatively and quantitatively. The purpose of this work was to determine the dynamics of HSW and hazardous waste generation and create in households a responsible attitude towards environmental conservation. For this analysis, the population was categorised into three socioeconomic strata (lower, middle and ...

  • You Don’t Need to Generate Waste Oil to Save Money with a Waste Oil Furnace

    Waste oil furnaces can save on energy expenses for businesses who convert their used petroleum products into fuel for heat. Cutting costs by recycling waste oil makes good bottom line business sense. And waste oil heaters also help companies act on their commitment to preserving the environment by reusing potentially hazardous waste and preventing it from entering the eco-system. For companies ...

  • Vanuatu government – Containerised general waste incinerator - Case Study

    TodaySure™ has recently constructed the installation of a containerised incinerator for the island of Vanuatu in the South Pacific Ocean. Permanently mounted into a modified 20′ ISO shipping container, which incorporated internal lighting, electrical sockets etc. The incinerator was fully tested and fired in our works and with the exception of the chimney, which is stowed in the ...

  • Generation and management of industrial waste in Small and Medium sized Enterprises

    This paper contains the results from the study and analysis of 100 Small and Medium sized Enterprises (SMEs) located in the Region of Castile and Leon (Spain), regarding generation, management, valorisation, treatment and final disposal of their waste. This study is an attempt to analyse the problems caused by industrial waste. To do so, an environmental survey was carried out on a random and ...

  • Assessment of major solid wastes generated in palm oil mills

    Two multivariate statistical techniques, viz. Discriminant Analysis (DA) and Principal Components Analysis (PCA) were used for the analysis of amount of solid wastes generated, such as Empty Fruit Bunches (EFB), potash ash, fibre and shell, in five different palm oil mills. DA identified two functions responsible for discriminating the mills on the basis of solid waste generated in these mills. ...

  • Survey and evaluation of household solid waste generation and compositions in Kuwait

    The objective of this study was to carry out a field survey of the solid waste generation profile in Kuwait. In addition, the paper examines the compatibility between household-estimated and landfill site-measured percent compositions of the daily solid waste. The true composition of daily household waste was determined via measurements of random waste trucks at the landfill sites. Hand sorting ...

  • Effect of different waste recovery systems on the overall waste generation rates for an Advanced Life Support System

    This work demonstrates how studies of life support systems can be used to advance the understanding of environmental principles. Efficient waste recovery systems that are developed for the Advanced Life Support System used in space explorations can be utilised on Earth. As an example, we explored three different ALSS scenarios, each having different waste recovery technologies. The results are ...

  • GIS-based modelling for the estimation of municipal solid waste generation and collection

    In the present paper, an innovative model for the estimation of municipal solid waste generation and collection is proposed. This model is part of an extended solid waste management system and uses a spatial Geodatabase, integrated in a GIS environment. It takes into consideration several parameters of waste generation, such as population density, commercial activities, road characteristics and ...

  • Pumps with extended service life for generating biogas from organic waste

    When regular commercial pumps are used to process organic waste, they typically wear out after only a short period of time. Liquids pumped under these conditions attack pumps from two different angles: first with highly abrasive additives and second with liquids that have highly fluctuating pH values and therefore a high level of chemical aggressiveness. These conditions are very tough on seals ...

  • Adsorption characteristic of As(III) on goethite waste generated from hydrometallurgy of zinc

    In this paper, goethite waste from hydrometallurgy of zinc was used as a raw material for arsenic adsorbent preparation. The goethite waste adsorbent (GWA) was characterized with scanning electron microscope (SEM), X-ray powder diffraction (XRD), and particle size distribution analysis. The adsorption of As(III) on GWA was studied as a function of contact time, pH, and coexisting anions. The ...
