Showing papers in "Waste Management in 2009"

TL;DR: Although primary and secondary recycling schemes are well established and widely applied, it is concluded that many of the PSW tertiary and quaternary treatment schemes appear to be robust and worthy of additional investigation.

TL;DR: The main conclusion of the overall assessment of the literature is that the evidence of adverse health outcomes for the general population living near landfill sites, incinerators, composting facilities and nuclear installations is usually insufficient and inconclusive.

TL;DR: Qualitative analysis of all 23 case studies identified barriers or incentives to recycling, which resulted in the development of factors influencing recycling of MSW in developing countries.

TL;DR: This literature review discusses specific issues related to handling of waste containing nanomaterials to highlight problems related to uncontrolled release of nanoparticles to the environment through waste disposal and to introduce the topics of nanowaste and nanotoxicology to the waste management community.

TL;DR: This paper conceptually evaluate issues surrounding the sustainability of SWM and proposes a multi-pronged integrated approach for improvement that achieves sustainable SWM in the context of national policy and legal frameworks, institutional arrangement, appropriate technology, operational and financial management, and public awareness and participation.

TL;DR: The results show that both fly ash and bottom ash can be utilized as source materials for the production of geopolymers and the moderate NaOH concentration of 10 M is found to be suitable and gives fly ashand bottom ash geopolymer mortars with compressive strengths of 35 and 18 MPa.

TL;DR: It is concluded that further research on the phase development during cement hydration in the presence of heavy metals and thermodynamic modelling is needed to improve effectiveness of cement-based s/s and extend this waste management technique.

TL;DR: Due to the large volumes of waste generated, the high moisture content of the waste and the changing waste composition as a result of process conditions, recovery methods are usually expensive and their environmental impact is still uncertain.

TL;DR: Evaluating the generation, characteristics, and management of solid waste in Malaysia based on published information finds that in general, the per capita generation rate is about 0.5-0.8 kg/person/day in which domestic waste is the primary source.

TL;DR: An ongoing study on the use of prefabrication in buildings and its impact on waste reduction in Hong Kong revealed that construction waste reduction is one of the major benefits when using prefabrica compared with conventional construction.

TL;DR: In this paper, an assessment of the existing situation of municipal solid waste management (MSWM) in major cities in India is presented, and an action plan for better management has been formulated; both are presented in this paper.

TL;DR: The mortar bar tests demonstrated that the finely crushed waste glass helped reduce expansion by 66% as compared with the control mix, and the results proved 80% pozzolanic strength activity given by waste glass after 28 days.

TL;DR: A waste generation and composition analysis is described and a comprehensive review of municipal solid waste management (MSWM) in Pudong is provided and the current situation will be evaluated, and its problems will be identified.

TL;DR: The state-of-the-art of waste management in Southeast Asian countries will be outlined in this paper, followed by waste generation rates, sources, and composition, as well as future trends of waste.

TL;DR: Results indicate that PET-filled concrete, when volume proportion and particle size of PET increased, showed a decrease in compressive strength, splitting tensile strength, modulus of elasticity and ultrasonic pulse velocity; however, the water absorption increased.

TL;DR: The P-bioavailability was significantly increased due to the formation of new mineral phases such as chlorapatite, farringtonite and stanfieldite during thermochemical treatment, which shows that these objectives have been achieved with the proposed process.

TL;DR: This paper focuses on waste-to-energy and especially its current status and benefits, with regard to GHG, dioxin and mercury emissions, energy production and land saving, on the basis of experience of operating facilities in USA.

TL;DR: The present work describes the waste management model that has inspired this decree: the Alcores model implemented with good results in Los Alcores Community (Seville, Spain), and a detailed model is provided to estimate the volume of waste that is expected to be generated on the building site.

TL;DR: More is possible and more is needed before Dalian can be designated a true 'eco-city', according to the approach used in implementing the circular economy concept in Dalian, which can provide guidance for other Chinese cities.

TL;DR: This paper shows that recycling rates already achieved by the informal sector can be quite high, typically in the range from 20% to 50%; often up to half of this is in the form of clean, source separated materials collected directly from households and businesses by itinerant waste buyers.

TL;DR: Investigation of the fresh and hardened properties of lightweight aggregate concretes that are prepared with the use of recycled plastic waste sourced from scraped PVC pipes to replace river sand as fine aggregates finds that the concrete prepared with a partial replacement by PVC was lighter, was more ductile, and had lower drying shrinkage and higher resistance to chloride ion penetration.

TL;DR: This paper proposes the use of geographical information systems (GIS) 3D route modelling software for waste collection and transportation, which adds one more degree of freedom to the system and allows driving routes to be optimised for minimum fuel consumption.

TL;DR: This study proved that the dewatered sludge melting scenario is an environmentally optimal and economically affordable method for sewage sludge treatment.

TL;DR: Lack of suitable facilities and underestimates of waste generation rates, inadequate management and technical skills, improper bin collection, and route planning are responsible for poor collection and transportation of municipal solid wastes.

TL;DR: The aim of this study is to compare the three methods, keeping in mind the costs that would be incurred by the respective governments, and identify the most economical and best option possible to combat the waste disposal problem.

TL;DR: It is recommended that an inventory of all construction waste generated in the country be carried out in order to assess the feasibility of large scale recycling of construction and demolition waste.

TL;DR: Composting scenario, S3, is the more environmentally preferable alternative to the current waste management system and might be supported with other decision-making tools that consider the economic and social effects of solid waste management.

TL;DR: An overview of current municipal solid waste management in Rasht city, Gilan Province, Iran, is presented and recommendations for system improvement are provided.

TL;DR: The study shows that increased solid waste generation of KL is alarming and it has been observed that the city is still lacking in terms of efficient waste treatment technology, sufficient fund, public awareness, maintaining the established norms of industrial waste treatment etc.
