The emerging model of waste disposal, develops an integrated approach based on waste reduction, selection, recycling, energy recovery and residual use of landfill. Here we discuss the fundamentals of a proper planning of waste disposal system, specially the thermal recovery, the integration and the methodological approach, either from the environmental and economic point of view. The growing demand for energy, the resulting environmental problems due to satisfy the demand for energy and the complex-economic system, necessitate the study of new technologies such as energy from municipal solid waste (MSW) obtaining as a result of decrease huge mass of solid waste to sanitary landifill and emissions of landifill gas as (CH4 and CO2 ). Therefore, we propose to validate a technical, economical and environmental analysis of waste-treatment systems with enphasis on generation of energy. The recovery of heat from a waste-to-energy plant, can make a useful contribution to the city energy needs. Whilst we have been slow to exploit fully this resource in Sicily, economically in urban areas.

Recent studies have demonstrated the high spatial, economic and ecological stakes of solid waste management in remote island environments, like Hawaii, but also suggested ways in which conceptions of risk and identity have factored into stakeholders' decisions regarding particular waste management technologies and processes. Through an analysis of historical and archival documents, this article examines linkages between a declining sugar plantation industry and the development of a major waste disposal project, and shows how an ecological identity narrative which combined an understanding of Honolulu as a place needing to reduce reliance on imported resources with an understanding of metropolitan Honolulu as a major centre for plantation sugarcane agriculture resulted in a plan for combining waste disposal with sugarcane processing. Focused on the historical case of the HPOWER facility on the Hawaiian island of Oahu, I argue that ecological identity offers new insights for understanding how environmental infrastructures are conceptualised and resisted, and that explicit consideration of ecological identity in the analysis of environmental governance may lead to improved scholarly understanding as well as improved outcomes for governance itself.

Engineered Landfill

The increasing volume and complexity of waste associated with the modern economy as due to the ranging population, is posing a serious risk to ecosystems and human health. Every year, an estimated 11.2 billion tonnes of solid waste is collected worldwide and decay of the organic proportion of solid waste is contributing about 5 per cent of global greenhouse gas emissions (UNEP). Poor waste management - ranging from non-existing collection systems to ineffective disposal causes air pollution, water and soil contamination. Open and unsanitary landfills contribute to contamination of drinking water and can cause infection and transmit diseases. The dispersal of debris pollutes ecosystems and dangerous substances from waste or garbage puts a strain on the health of urban dwellers and the environment. India, being second most populated country of the world that too with the lesser land area comparatively, faces major environmental challenges associated with waste generation and inadequate waste collection, transport, treatment and disposal. Population explosion, coupled with improved life style of people, results in increased generation of solid wastes in urban as well as rural areas of the country. The challenges and barriers are significant, but so are the opportunities. A priority is to move from reliance on waste dumps that offer no environmental protection, to waste management systems that retain useful resources within the economy [2]. Waste segregation at source and use of specialized waste processing facilities to separate recyclable materials has a key role. Disposal of residual waste after extraction of material resources needs engineered landfill sites and/or investment in waste-to-energy facilities. This study focusses on the minimization of the waste and gives the brief about the various initiations for proper waste management system. Hence moving towards the alternatives is the way to deal with these basic problems. This paper outlines various advances in the area of waste management. It focuses on current practices related to waste management initiatives taken by India. The purpose of this article put a light on various initiatives in the country and locates the scope for improvement in the management of waste which will also clean up the unemployment.

Pulp Production

The use of recovered paper as a raw material for paper production is by far the most economical and ecological strategy for the disposal of waste paper. However, paper production from recovered paper furnish generates a great amount of residues, and the higher the demand requirements for the end product, the higher the amount of rejected material. The reason for this is that the selectivity of the deinking process is limited; therefore, some valuable components are also lost in reject streams. The rejection of usable components affects the economics of recycled paper production. As the cost of waste disposal continues to increase, this issue is becoming more and more severe. This paper summarizes the current state of the resource efficiency in recycled pulp production and provides information on the volumes of rejected streams and the usable material within them. Various means to use these reject streams are also discussed, including the main findings of a recent thesis by the main author. This review summarizes current internal and external use of reject streams generated in the deinking operations.
