An Economic, Technical And Environmental Feasibility Study for Slurry Injection for Biosolids Management In the Dallas Fort Worth Metroplex
In Dallas Fort Worth (DFW), sewage is treated with a combination of anaerobic digestion, effluent filtration and lime stabilization to create biosolids which are then composted, landfilled, or land applied. The current treatment procedure has certain concerns including emissions or accumulation of odors, pathogens, nutrients, metals, and pharmaceutical ...

Effect of Incorporating Tire Rubber Waste on the Mechanical Behaviour of Railway Ballast Layer: Experimental and Modelling Studies
In order to delay the degradation of railway tracks, several techniques have been developed in recent years; the best known of which are: under sleeper pads, geogrid and the use of polymers as elastic elements between ballast particles. The objective of the research described in this paper is to evaluate the effectiveness of incorporating tire rubber waste into the ballast layer in reducing its ...

Efficiency oOf Municipal Solid Waste Collection Systems in Ghana
For purposes of establishing a benchmark against which performance of municipal solid waste (MSW) collection systems can be evaluated by sector regulators, investors and managers, this study assessed the cost efficiency of MSW collection systems in Ghana, using stochastic frontier analysis (SFA). Data from seventy municipal solid waste collection systems were used to estimate the parameters of a Cobb-Douglas cost function. ...

Experimental Research on Construction-Waste-Classification Algorithms for a Hyperspectral-Camera System
A large proportion of construction waste has a high recovery value, and some of the existing recycling-classification methods rely mainly on physical properties for vibration screening. In order to effectively recover construction waste, an industrial near-infrared hyperspectral camera is proposed in this paper to distinguish the spectral characteristics of the objects. The testing results were verified using an extreme learning machine, an ...

Household Solid Waste Management in Monrovia, Liberia: Influencing Factors, Characteristics, and Management Solutions
The ineffective management of household solid waste (HSW) in most developing cities in Africa including Monrovia has become a major issue threatening the environment and public health. In response to these waste challenges, developed countries have embarked upon major environmental reforms, and have made advances in best practices and sustainable management of their Municipal Solid Waste (MSW). However, in most developing countries like ...

Mineralogical Analysis of Portland Cement Pastes Rehydrated
Hydrated products, such as (hydrated) cement pastes, decomposition through physical-chemical alterations when submitted to high temperatures. One of the main factors that lead to microstructural changes during calcination up to 800ºC, is the dehydration phases of hydrated Portland ...

Recycled PVC as Material for Natural Fiber Composite Manufacturing—Study of Mechanical Performance and Durability
Manufacturing wood plastic composites from polyvinyl chloride (PVC) construction waste is one of the options for its continuously increasing scrap utilization. The aim of this study is to estimate the mechanical properties and durability of composites manufactured from recycled and commercially available PVC ...

Selecting Sustainable Technologies for Municipal Solid Waste Treatment and Disposal: An Expert Based Mcdm Approach
Selection of appropriate municipal solid waste (MSW) treatment and disposal technology is a complex multi-criteria process. This paper demonstrates the reliability of the use of multi-criteria decision-making (MCDM) framework for the purpose of selecting the best MSW treatment and disposal alternatives. In this paper, a modified fuzzy Delphi-AHP-TOPSIS methodology is developed for the selection of the most appropriate MSW ...

Solid Waste Management Policies in Kenya: The Silence on the Plight of Women and Children
Building on available evidence that there are differences of exposure to solid waste among men, women and children, it follows that effective solid waste management (SWM) policies need to recognise such variations, as a prelude to rolling out programmes to address associated socio-economic and health risks. However, this logical scenario does not seem to be the case in many middle- and low-income countries. In this paper, we ...
