An inventory of material and energy consumption during the construction and operation (C&O) of a typical sanitary landfill site in China was calculated based on Chinese industrial standards for landfill management and design reports. The environmental impacts of landfill C&O were evaluated through life cycle assessment (LCA). The amounts of materials and energy used during this type of undertak...

Various nations in the world have developed technologies and strategies for appropriate waste disposal, and to abate waste generation and greenhouse gasses. Alternatives like recovering materials can help, but they require reliable information to improve planning and management. This study quantifies the Carbon dioxide (CO2) emissions produced by the lack of valorisation of materials in a Mexic...

In Romania, the waste materials problem is becoming more and more acute due to the increase in their quantity and of the negative impact on the environment. An important waste category is represented by the medical solid waste materials that belong to the high contamination risk category. The source of these waste materials is hospitals and clinics typical units from the point of view of the ge...

The main aims of solid waste management are to protect the environment and human health; and, to conserve natural resources. However, increasing consumption, environmental issues and resource depletion threaten its sustainability. Solid waste management policies usually fail to reduce consumption, decrease environmental impacts, conserve raw materials and develop sustainable products. These pro...

Building energy efficiency and urban waste management are two focal issues for improving environmental status and reducing greenhouse gas emissions. The main aim of this paper is to compare economic costs of new building envelope structures designed by authors reusing and upcycling municipal waste in order to decrease energy demand from the building sector and, at the same time, improve eco-fri...

Solid filtered or centrifuged potato processing wastes were obtained from three potato processors in Idaho. The waste samples were dried and ground to pass a 2-nun sieve and added to soils at rates of 0, 2.5, 10, and 25 g/kg. The 100-g samples of Portneuf silt loam soil containing the waste material was incubated at 26 °C and decomposition of the added wastes was determined by measuring CO, evo...

The flow of fluids in complex geometries like porous media [1] plays an important role in a wide variety of technological and environmental processes including chromotography, oil recovery, the degradation of building materials and the spread of hazardous wastes in soils. The complexity of such flow processes makes their theoretical and experimental study a great challenge. Recent developments ...

Recently, issues concerning the sustainable and harmless disposal of organic solid waste have generated interest in microbial biotechnologies aimed at converting waste materials into bioenergy and biomaterials, thus contributing to a reduction in economic dependence on fossil fuels. To valorize biomass, waste materials derived from agriculture, food processing factories, and municipal organic w...

Hurling a successful Construction and Demolition Waste (C&DW) recycling operation around the globe is a challenge today, predominantly because secondary materials markets are yet to be integrated. Reducing, Reusing and recycling of (C&DW) have been employed over the years, and various techniques have been investigated. However, the economic and environmental viability of its application seems l...

Lightweight ceramic materials in the form of bricks and blocks are widely used in modern construction. They may be obtained by adding of rice husk, rye straw, etc, as porous forming materials. Rice husk is a major by-product of the rice milling industry. Its utilization as a valuable product has always been a problem. Various technologies for utilization of rice husk through biological and ther...
